i recently bought a factory offered single clarion unit with the electronic tuner and tape deck. the factory also included a graphic equilizer although it was not included with my purchase. i plugged the radio in hoping that it would work.. when i turned it on and off the power anntenae goes up and down but there is no sound.. if i push the tuning button in the station frequency shows but will disappear when i let go.. also when i push two times quickly and hold the clock shows.. maybe the connection is bad for the electronic tuner? even if i hold the tuner button with the frequency showing there still is no sound.. maybe it works only if the equilizer is plugged in also? any help would be greatly appreciated.

almost forgot.. behind the unit has a 3 prong solenoid shaped like a plug.. one prong solendoid like a rectangle (both are white outer shell that have edges.. no curves) then there are 2 white circular solenoids... one 8 prong and the other (which had a cap on it) a 6 prong. another circular solenoid is black also with 6 prongs. also an anntenae outlet to recieve radio signals.. some punk stole this exact radio a few years ago and now im buying the same parts back to install.. i believe when this punk stole my radio he cut one of the solenoid plugs ( the single rectangular plug). so i plugged in the black 6 prong to a black 6 prong and the anntenae male to the female on the radio and the 3 prong plug shaped from my radio to wires behind my dash... it has power but no sound...

i have another more basic radio also from clarion which is an analog one where u have a needle to point to the frequency... i just need these 3 plugs and it works fine.. so i dont see why this one i bought doesnt work.. unless u got it handed to me..

the premium radio relies on two dual channel amplifiers to power the speakers... the large 6 pin din connector coming out the back is the line level audio that should be passed to the EQ, which feeds line level audio to the "joystick", which splits the audio front to rear and drives the amps..

you dont have amps, thus you dont have sound. i doubt the premium deck has any power amps in it, cuts costs (my supra is exactly the same.. no joystick tho

I have an extra stock amp laying around if you want it. Only one though. For some reason the previous owner removed one and left the other when he upgraded the sound system. PM me if youre interested.

i talked to my dad about this since my RX-7 used to be his.. back when he still had his whole premium sound system intact with deck and eq and amp and joystick balancer he told me that he could turn off the eq and still have the deck on and play music. temporarily i have another clarion unit that was a standard one offered by mazda also which is the one **** on the right side which is all manual. on the back has a 6 prong solenoid and 8 prong and the 3 pin and single pin plugs on the back. i plugged the black circular 6 prong plug and the 3 pin plug with the anntenae plug and the whole unit works with all the speakers and also with the joystick balancer... so i dont think i need a new amp.. im thinking the premium deck is not working.. or it needs an eq to play along with it.. im not sure but if anybody has a factory premium sound system that works with the eq thats all i need and pm for an offer. thanks.

i have the entire system and im just about to remove it from my car

it works fine, even the tape deck

when you move the volume control it makes a scratchy sound
but its only when you move the volume. once you have it where
you want it it sounds fine.

make me an offer. i can sell you everything including the speakers, amps, etc

what kind of sound system is your "entire system"? are they factory clarion units? one complete unit includes electronic tuner/cassette deck and the bottom is the graphic equilizer? all my speakers work as of now but some are stronger than others... i dont think i need an amp.. but would be nice to have one i guess.. and i have a functional joystick balancer.. so reply back to confirm with me what your system is and if its posible to just get the deck and eq. thanks.

i appologize that i did not make this clear in the first place but my car is a 82 gsl

oh crap, i just grabbed my old, cannibalized deck... looks like the eq signal is pre-fader, meaning sound is passed to the eq, then BACK to the deck for the myriad controls, then passed to the joystick, then amps.

your deck will need a bypass connector that just shorts the input and output of the eq together to simulate an eq doing nothing, then it will work find.. kinda like a blind plug. nobody will make or sell you this. this is not a stock option.

the black plug should go into the eq, and thats the guy you'll have to reverse engineer to get sound out of the deck... or get an eq.

poop on the stock stereo!!! I couldnt pick up a station even if I was right under the brodcast station! Sorry I just had to get that out!!

But yea I agree with spakien up there. You need to make it think that there is something there to complete the loop. Kinda like your head lights switch there in your console. It needs to be pluged up in order to keep the loop of electricty so the headlights will go down!

nothingbutrotor

Thats definately no lie. The stock radio has crap for reception, if I want to listen to the radio I get 2 stations, classic country, and classic rock. But before long, I will be changing that out with my JVC deck and polk speakers.

But I still think you need those 2 amps that are underneath the storage bins, otherwise the speakers won't have enough power to play. Turning the equalizer off has nothing to do with it, that just makes the signal bypass that and go straight to the speakers. Like one of the first people said in this forum, you need those amps.

my dad said there is an amp (im not sure if there are 2) under the driver seat.. never bothered to check.. anyways maybe this one is different from the standard ones that have just one **** for volume/power/station changer. because the standard one that i have right now is connected with 3 plugs ( the round black 6 point plug to another of the opposite sex plug, a white 3 flat pin to another of the opposite sex plug, and the anntenae plug) btw this standard radio works fine with pretty good receptions am and fm.. i guess the premuim radio deck since it needs to have a more complete circuit than the standard because it was paired with an eq... thanks for all your help so far and if anybody has a 81-83 premium sound system with the electronic tuner/cassette and eq ill make an offer.

ok i took some pictures... can anybody tell me what these plugs mean and where do they plug? i know what the antenae plug is.. and i know the 3 pin and single pin plug and 8 pin kuz theres only one of each.. but what do they all mean? and what about the 2 6pin prongs? what does the black one mean? what does the white one mean? thanks for all your help!

Connectors are as follows if you were looking at the back of your clarion premium stereo unit:

white 6 prong left side- front amp
white 8 prong center- EQ
black 6 prong right side - rear amp
white 1 prong - battery -
white 3 prong - antenna relay/illumination/battery +
black antenna connector
*not sure about your random plugs but they probably go to the "joystick" balance control and you should have another 8 prong connector for the tape deck. The tape deck connects to the EQ and the EQ connects to the tuner.

You have shown that you do infact have the connectors for each of the two amplifiers. Each amp, front and rear, provides power (25w X 2 per amp) to the 4 speakers. You need to check if the amplifiers are still behind the storage bins, if they are not there or if they are there and not getting power then there is your problem. Find out some more information about the amplifier under the driver's side seat.

You can refer to section 15-62 of the Mazda Rx-7 Workshop Manual, in the link below, if you have anymore questions about the wiring and/or connectors :

Couldn't load the 82' workshop manual, so I had to use the 85' workshop manual. Hopefully your stereo's set up isn't that different. Sorry

After 12 beers and 6 whiskeys: I gotta say onj a non premium sound I fiound an amp behind the driver side cargo area.

hey thanks for all your help guys!

when i check my amps what do i check for? so theres the front amp under the drivers seat and second in the back under the drivers storage bin.

also i cant seem to find the single pin plug inside my center consel. if it is missing can the radio and eq still function? i found a wire that seems to be cut. can i buy a plug and solder it to the wires?

ok i got some pictures of my counsel. it seems like i dont have sufficient plugs for the radio... interesting because my car came factory with the premium sound system..

these are the plugs i plugged to this radio: http://i3.photobucket.com/albums/y89...er/file-11.jpg
back:
and everything works fine! even the joystick balancer!

looks like it plugs to something.. the battery (-)???

plugs into the EQ? theres a spot for it on the radio pictured above but seems like its not needed for the radio above to function..

black and white plugs from the joystick balancer seems to be plugged right.. maybe leads into the amps...

closer pic.. and both these plugs are PLUGGED to other plugs maybe amp plugs..

thanks to everyone who have helped me so far! i found the amp behind the driver storage bin and the amp under the driver seat.. so the white plug (left 6pin) goes to the front amp and black 6pin (right) goes to the rear one.. can i run on just one amp with the premium? seems like i can with the more standard radio.. but the three plugs (black 6pin, antenae, and the 3 prong plug is all i have behind.. maybe the EQ has the white 6 pin plug.. then im still missing the single prong plug and the 8 pin plug.. basically i only have half the plugs to match up to the premium deck.. well once i get an EQ i will find out more..

AGAIN THANKS FOR ALL YOUR HELP! i hope to resolve this problem soon and have a working premium sound system again.

alright i took some more pictures with a better digital camera this time. here there are:






when i bought it, the white 6pin came capped.. and i dont see a white 6 pin in my car's radio harness to match up either. only a black 6pin to match up.




the wires i have hooked up to the more simple radio and with these 3 all speakers work, am/fm works, joystick works, basically everything works. obviously i want a premium sound like i originally did. and want it working too.

dont have a plug for this for the premium deck, but can plug to the more simple radio. dunno what it does tho..

wires out of joystick

closer

closer.. notice they are plugged already so i guess i dont have to touch those..

eq slot


driver storage bin amp (rear)

another view

driver seat amp (front)

so these are the pictures ive taken today. hope this helps. again i greatly thank all of you for all your help and info provided. once i get my eq in i have more wires to plug up to and ill update when i get it in. thanks again and have a happy new year!

alright! today i finally got my last piece to the puzzle. my equilizer finally came in!! pics!!:


complete system

another view



notice where eq plugs into

3 circular plugs (top to bottom): 6 pin black (front amp), 6 pin white (rear amp, capped), antenna plug (correct me if im wrong please). also u can see 3 pin plug, battery back up plug (not used), and eq pluged


ok the outcome was that everything had power: radio, eq, and joystick balancer. not sure if rear amp gets power because i cant find a plug for it and the radio came capped too. i think there is a bad connection or ground for the tuner because i have to hold it for it to display a station 87.9 FM. if i let go it goes back to static and screen goes blank. i cant change stations either because when i hold it turning the **** wont change stations. ill look into this and if i cant fix it, i will buy another one. so if anybody has one collecting dust and it must WORK ill buy it!

i want to also thank everyone who has helped me out! everything was all new info which i appreciated to learn! i cant thank everyone enough! thank you to everyone on this forum and especially those who made an effort to post a reply and helped me out! THANK YOU!

so i recently bought another complete factory premium sound system which includes electronic tuner deck, eq, joystick balancer, and 2 amps all complete with their wiring harness. i have the same problem again. that is when i have hooked up everything which includes the black 6 pin cannon which feeds to the joystick balancer and from there to the 2 amps. then back to the deck i connected the white 8 prong cannon to the eq. then i connected the 3 pin plug and the eq lights up red and the tuner deck has power and the power antenna moves up when on and down when off. except there is no digital display. only when i hold the tuner **** there is a station display and if i let go it goes away with static. i cant tune to a radio station when i hold it in i guess because thats just the way the recall works. is this a ground problem? am i not getting a constant to the tuner ****? what is wrong with my deck/tuner ****? any help is greatly appreciated. i have the factory repair manual but i cant understand the wiring diagram that much because i very minimal wiring knowlege. i understand that black plugs go to black and white to white and what fits fits and it seems to work. this problem has also occurred with my other deck except after i air cleaned it and hooked it back up when i hold the tuning **** there is no display at all. maybe a bad connection. and by the way there is a blue yellow wire that looks stripped of a pin... i cant find where it would go or see it in the radio wiring diagram. dam im so frustrated.

anybody have any idea? i know not too many people care much about the old outdated sound system but i am doing a complete restore as close to factory specs as possible for my car. please any help or tip would be greatly appreciated! thank you all and have a great day!

i have a feeling that the "random cut wire" (pictured way above, LY (blue with yellow stripe)) is missing a harness or one of those single-hole-white-box-plug-looking thing which is pictured in the 1983 factory repair manual is connected to the radio and it is the battery or constant. if i am wrong please correct me. i believe i am missing this plug to plug to my stereo system which is causing me to hold the tuning **** for a display and sound. when i hold the tuning **** i cannot change the frequency. when i let go the display goes away and no sound. please help me out here if you can. otherwise i might have to try my luck at a junkyard and find an RX-7 with a premium sound system attached and see how it is wired. and maybe bring a battery to see if it works as it should. thanks for your time.

i found a picture of what i think is missing



it is the second harness.. the single pin one. i think i am going to radio shack to pick up the white plastic housing and pin because i am missing just that piece and do not need the kit. people that have or had stock premium sound system like i am trying to put back together please if you recall let me know that by having this one more plug i do not see on my car make my stereo system work. i did have the premium stereo system in my car before until it got stolen. i see a spliced blue with a yellow stripe wire which in the manual says i have to connect so im pretty sure with this plug it will work constantly. thanks in advance.
