What are people doing about the center speaker on top of the dash? Are people hooking it up and does the adapter allow for this? Does it require a 5th line?

WaLieN

I'd like to know this as well -- I've heard taht the center speaker isn't a true ch. anyways, it's just a mix of the front L&R speakers.

I just talked to Crutchfield tonight and they now recommend this adapter...
http://www.crutchfield.com/S-rEZeJgv...sp?i=142C4MA02



I'm buying the Alpine CDA 9815 for my FD


With this adapter it should be just plug and play! It doesn't utilize RCAs but speaker level inputs, but I'll be getting all new speakers eventually. I've been driving around with no radio or CD player for 3 months, so it will be nice to have music again!

BTW: I'm not buying the HU from Crutchfield because they want $499! I found another large retailer online that will sell it for like $360 and I'm buying an "extended warranty" for $30 since they are not an authorized Alpine dealer.

hey guys, the best way to do it if u can't find the right adapter is to test everything as u go and install it right. take a voltage meter and put it on dc current. test for 12 volts. ok put the balck probe on ground and the red probe on any wire u want to. when u get close to 12 volts with the car off, that is ur battery. turn the key and test for ignition. it should turn 12 volts on and off as u turn the key on and off. amp turn on is the grn with black stripe. and in order to use a high level/lo level adapter for rca's u need to hook up the speaker outputs from the radio to the adapter and out from the other side u have ur rca's. if its only for a sub then keep the speaker wires hooked up to the speakers as well as the adapters. if u need any further help let me know. good luck

Though I ordered that adapter from SoundDomain, they ended up sending me this one...
All in all, this was a better solution anyways. Though it is quite large, it does fit very well even if you have a little cubby below your deck.

if your new deck has pre amp outs why not just use them with a $5 radio shack adaptor?

Maybe this post I did elsewhere will help, maybe not, but check it out.:

Because the purpose of the adapter is to lower the output of your radio so that it can be channeled through the Bose Amps.

The trick is to put your radio on FULL blast and have the gain on the adapter as LOW as possible. Slowly turn up the gain on the adapter until the music starts sounding like ****. Then slowly turn it back just before it sounds like ****. Now you can turn up the radio as much as you can knowing you won't be destroying the stock amps or speakers.

the centr channel isn't a true channel unless maybe you get a DVD player with a dolby decoder. then the center channel would work out nicely. Anyone done this?

Of course the center channel isn't a true channel. In the original Bose system, it was designed as a tweeter which filled in the highs.

I got a quick question and this will probably be retarded but I'm still learning a lot about audio systems and wiring.

My new headunit (Pioneer DEH-P8600MP) has this harness with the 12v+, ACC, ILL, and front (W, W/B, G, G/B) + rear speaker (Gr, Gr/B, V, V/B) leads. I'm assuming these are the pre-amp outputs that dont utilize the internal HU amplifier?

It also has a connector that plugs into the rear that splits into RCA connectors for FRONT, REAR and SUBWOOFER and says in the manual "Use these connections when using the optional amplifier".

Now I have the Schosche adapter as well, do I want to use the W, W/B, G, G/B, Gr, Gr/B, V, and V/B on the first connector or do I want to cut the RCA connectors and use those lines for the 'optional amplifier'?

I didnt see this discussed yet but I may not of looked hard enough. It would look like I'd use the first lines since the colors match up on the Schosche adapter but the 'optional amp' lines look specific for a subwoofer which may be better for the BOSE snake.
Thank you very much for any help you can offer,

I didn't use the RCA connections -- I used the wires on mine.

JaNusSolSumnus

Oh okay, so I'll just wire the rear WAVE system to the rear outputs on the HU line-level outputs then.

I cant remember what the exact reasoning behind needing the adapter was. I mean I know the BOSE system has the amps on each speaker and a wacky 1.5ohm impedance but I cant remember what was said about the effects. Wiring the system up to a headunit without the Scosche adapter; will it fry the HU or amps/speakers -- or will it just sound shitty? I read in the manual for my HU it requires speakers with a 4 or 8ohm impedance so I'm assuming it is damage that will occur to the amps directly wiring it?

Thanks,
~Kris

WaLieN

Yes, your wave subs are considered your "rear" speakers.

The basic function of it is to convert the amplified signal sent by the Head Unit into a non-amplified signal. It is to protect your speakers/amps.

JaNusSolSumnus

Well that is where I am confused -- if I am understanding this correctly, the RCA's are amplified by the internal amp in the HU. The regular wires are 'pre-amp' so they shouldnt have any amplification at all... agh, sound systems are teh confusion. :/

~Kris

WaLieN

I'm not sure about your RCAs, but the RCAs on mine usually aren't amplified. Think of it this way -- if you were to get an aftermarket deck on a base/R1 audio system, how would it power the speakers? The wires coming from the harness are amplified, which is why you need a line converter.

I have a 93 and am in the process of replacing a dead HU with a Pioneer that I have had lying around and can't quite get it all working. I have the scosche adapter that is reccomended from my stereo shop, I wired everything up according to the diagrams but got no sound. I clipped out the black/green wire and hooked it up to the blue/white wire and I have sound, but only in the dash and door speakers, nothing from the rear tubes. Also my antenna now goes up whenever it is on instead of only the tuner. Also how are people hooking up the antenna, I have 2 plugs (no idea what they are) that go into 1 big *** wire thing that was directly into the radio? I would ap[preciate any help as I have been working on this for around a week now and I am going nuts.

WaLieN

The one I got had a manual that told you which wires go into which slot. I have a Sony headunit, and it worked fine with the power antenna (only goes up when the radio is on). I would check with your manual to determine whether or not you have it wired up correctly. Also, you might not be getting sound from your Bose subs because the amp/speakers might be blown.

If I were you, I would recheck your wiring with the manual. If all of that is correct, then it might just be that your rear amp is blown.

idogg

I double checked the manual and everything seems to be hooked up correct as far as I can tell. The rears worked fine before hooking up the new stuff. I am prob just going to take it into a shop because I am sick of messing with it....stupid Bose systems...

WaLieN

Your rear amp is probably blown. Switch up the wiring on your harness so that the rears are in a working channel to test if the rears are in fact blown.

I want to replace the factory BOSE system with a relatively simple system of my own. If anyone on this site is familiar with Crutchfield, then I will tell you that I found a nice JVC head unit and speakers that I like, which according to Crutchfield will fit in the car. Before I go out and purchase these items, I wanted to get as much info as possible from others who might have done this already. Please fill me in on anything I should know or look out for. Hell, even a complete set of instructions on how to do it would be great!! Thanks.

this thread pretty much told you everything you need to know

Dane

Questions:

1 - Is your Bose system having problems, or are you simply wanting to change the deck?
2 - How serious are you about sound quality?

By the way, I wouldn't put much stock in Crutchfield's advice, however they are a good company as far as shipping, availability, etc (if money isn't an object). However, I have had a few dealings with them directly and indirectly due to my customers being initially given bogus info about what will and will not work or fit. Luckily after a few letters, I was able to apparently convince them to put a "we don't know" comment on a few items they originally said would not fit at all - when in fact I had installed the exact item in the car they said this about in many cases.
I run a company called zmaxsystems, and I build custom Bose replacement systems mainly for 300ZX's and Maximas, and have also built a few custom setups for 3rd gens. However, to be totally honest with you, the stock Bose system sounds much better than anything on this side of $XXX (when it is working properly). Sure, you can spend some big bucks and add a true subwoofer (read-heavy) and make a killer system, but for most intents and purposes, you should just run with what you have. Obviously I am being honest because I could potentially sell more custom systems if I were to say the Bose systems were crap. But then again, I guess someone could say I also might say this to sell more Bose parts (:
Anyway, let me know more about what you are looking to do, and I will try to advise you a little more.
