I did a small search and notice somethign about a code.

Let me give you the diagnostics.
I get static sometimes but I only hear the bass from the subwoofers.
The radio says Err which I guess means Error. Do I only have to put in the code will this fix it? Thanks

 

Ok i inputted the code, now its spitting CDs at me. I at least got the clock on it.

 

Bump
I got the code in and it stopped giving me the error message now I just cant make it read a CD. The radio wont work for now since my brother broke the antenna.

 

i have the same issue with the stock cd player. it tries to read it but it spits it out. tried using a brand new cd, a cd drive cleaner, cd-r, and nothing. the cd drive cleaner does not stay in long enough to clean.

 

Let me know if you fix it anyway.

Bump to get info.

 

looks like its time to just invest in a mp3 cd player and new speakers.

CD player does not accept CD's, accepts but won't play, spits CD's back out
$150-$190

 

I heard you cant use the bose speakers with an aftermarket deck is that true?

 

i believe theres a hack or something to use bose speakers with aftermarket radios. too lazy to search maybe someone thats not as lazy can find the site to what wires to splice.

 

how do I disable it?


I no longer have the stock stereo so I have no place to input the code, if thats where the code was once put...

 

get a new headunit, I replaced my stock headunit and the entire system sounds SOOOOOOOOOOOOOOOOOOOOO much better... it actually makes the boze liveable.

 

and you can use the bose speakers with an aftermarket headunit,

i got the wiring harness at best buy, however the problem is that the harness dosent pass through a power for the bose amplifiers, so you have to locate which wire in the stock harness isnt being used with the new harness and jump that wire to a switched power on the headunit (remote lead)

it will work perfectly after that.

carstereohelp.com is a really decent honest shop. Once my stereo didn't sound right. it lacked bass and the sound levels were uneven left to right. I sent the 2 front and 2 rear amps in to be refurbished. Bob at carstereohelp.com called me back and said he couldn't find anything wrong with the amps. he even refurb'd one to see if it made a difference...it didn't. He only charged me for shipping back. He told me to send in the head unit as the problem must have been there. Somehow when I hooked it all back up it sounded okay again. There was a rattle from one of the bass tubes. Turned out the dust screen was loose and was rattling and popping so that it sounded like a distorting amp or blown speaker. I took it off and replaced it with a piece of panty hose. Works great. Now if I could only hear it over the single turbo, and straight through exhaust!

 

i talked to bose last week, they wanted like 40 for each speaker, and 40$ each to refurbish the amps.

not worth it IMO cause bose blows :P

 

Sooo which wire is for the bose amplifiers? I'm trying to troubleshoot why my new headunit doesn't work. The seller sold me the car with a deck, which powers on but doesn't have any audio. I'm guessing that the wire isn't hooked up, so does anyone know which color it is?

Oh and where is the center bose amp located? Center console maybe?

Bose typically fails in two ways:
1) the amps in the speakers blow out, caused by failure of a capacitor. Bose used Nichicon caps, which are junk. Sometimes the failure just causes bad sound or something less dramatic. There are maybe 12 caps per speaker amp, and you can buy Panasonic brand replacements for around $2.00 per amp total. You just need to know how to solder and replace them all. I've done this myself on my Nissan Maxima's Bose system, and all four amps required under $15 in parts. It took me about an hour per amp to do; an interested little project actually.

Edit: I saw the details of the RX-7 Bose system on the link - it appears in the 7 the amp is not on the speakers, so repair may prove to be even less labor intensive.

2) the headunit has a similar failure. I know people have fixed it, again for dirt cheap. The cost (www.carstereohelp.com's prices basically are just shipping and labor) is nearly nothing if you do it yourself. The error codes you see indicate a problem with the headunit - I don't think it will detect a speaker problem. I haven't attempted fixing one, but I do know of some links on the Internet which describe the procedure.

You can install an adapter to use Bose speakers/amps with a normal headunit. One is made by Scosche and runs around $50. I use one in my Maxima and it works just fine.

Well thanks for the replies. Turns out previous owner (I've had the car less than a month) removed all the Bose and installed custom speakers with a 300w alpine amp . Frustrating to find out the amp was under the plastic in the back seat, yet rewarding at the same time. Thanks for the help.
