Who's replaced the Bose head unit? I've done all the searches and can't find my answer.

I have the converter with all the speaker wires soldered, and the head unit turns on fine, but with no sound. Calling tech support, I was informed that somehow, the amps are not being turned on in the car (makes sense) and that usually a pink wire is used to turn on the factory amp. When I removed the stock head units, the antenna and other main cable that's attached with it had the few little wires (with white connectors inside the head unit discussed in other threads) and they uhh, ripped. However, one is PINK and one is GRAY, so I hard wired the blue/white amp/antenna turn on wire from the new head unit to the PINK wire as directed by the tech support and still no sound. I see the Bose wiring diagram, forgive my inability to make 100% sense out of it. What else do I need to do, or is that wrong? Is that gray wire a ground that need to be connected? ~ I have none of the antenna stuff hooked to the new head unit, I plan to buy a different antenna, because I see no way to hook it to the new unit (even though I have a male/male adapter that Crutchfield said I'd need and that I've read about in other threads, I can't find any connector at all on the antenna, just thos wires w/conn inside the old units).

How do I turn those amps on????? Thanks boys and girls!

Hey, I'm going through the same thing you are right now. I'm getting power and all, but no sound no matter what I do. I was unsure of where my antenna would plug into too since the connection flew back into the head unit area somewhere. I finally found it deep in the right side of the head unit area and this happened because the connection is too short. So, search around deep in the right side to see if you can find it. I tired to go to Circuit City today to get some help, but the stupid roadshop guys all went home early so now I have to wait until Wednesday to get this crap sorted out. 7-sins responded to my post in this section and he said that a wire was missing out of his harness, so maybe it's not us at all and just that everything is not right with the harness itself. Anyway, good luck with your problem and let me know if you do figure something out cause I'm completely stumped.

Guys, look at the bose wiring diagram I have up.

There is a wire that triggers a relay which then sends power to the bose amps. An aftermarket radio obviously wont have the connection for this wire. What you need to do is bridge it with either an amp trigger connection on the radio or to ignition. Don't hook it up to constant power because then your battery will drain overnight.

I see the diagram I assume it is the "radio relay." I have the amp turn on wire from my head unit located no problem, but on the wiring diagram, does it go to the L/W (blue&white) wire on the relay, and is this wire in that bundle of shielded wire clipped to the antenna cable?

Thank ya

Ahh, no, I am thinking the LG/B wire?

Flybye

Yep yep
If you notice, the cable on the left side of the relay is attached to direct power. Once the relay is activated, the connection is closed thus sending power to the amps.

Everything works now

Just to make it very clear for others, connect the power ant/amp turn-on wire from the new stereo's wiring harness (BLUE with WHITE usually) to the LIGHT GREEN/BLACK wire on the larger of the two factory wiring connectors, and Enjoy the boom.

YEEEEESSSSSSSS!!! I LOVE YOU FLYBYE!!! I JUST WANNA KISS YOU ALL OVER!!!! I gave the LG/B wire some power and my car started filling up with sound! Worked like a charm! I owe you a brand new Bathurst Type R RX-7!!

One more thing, where would you recommend I put the wire that controls my power antenna?? It goes up whenever I have the unit on tuner or cd, but it's not wired into the ignition connection. I forgot exactly where I put it, but I think it's a solid blue wire that's labeled as the one for a power antenna from the head unit harness.

Merciless

you are correct...th blue is always the remote tune on wire for amps/antenna

Flybye

The antenna power wire is the Green wire with the Orange Stripe. Disconnect it from the harness and attach it to the antenna wire, and you should be ok

Hey Guys, is the converter from Crutchfield the one that everyone is using?? The price they gave me is $49.99 and part # is 142CMA02.
Also, they told me I need a connector for my antenna. Is this correct? Should I order that connector along with the Converter???? Thanks guys.

badass7

alright, this is where I'm at now. Waiting on the converter and antenna connector from Crutchfield that should be in tomm. So, I took out the Bose head unit and cd player and what I see are two harnesses and one wire which is the antenna wire to the right. Now where do I go from here?? I don't have the parts yet but what I take from reading this thread is that everything will hook up except for a wire that powers the amp...which doesn't even exist?? Does this mean I run that wire to the ignition power. If so, where is that located??Also, do I have to rip those clips off the stock harnesses and splice the wires together or will the converter deally from crutchfield just plug into that??

I know the Mazda BOSE adapters we sell (AAMP/Best Kits) have the harness to plug directly in to the Mazda one, all you have to do is match the colors from the deck harness to the adapter and BAM you are done, no cutting no nothing!!!

I'm kind of confused as to which adapter I should be using..

or

one is $29 and the other is $49

I wouldn't be worried if yours looks a little different. Mine certainly does, but I got mine over 4 years ago.

This is what I had done. Since my new deck does not have a dimmer control, I removed the pin from that slot, and hook it in where the amp power supply should have been. It made for a clean install. Thanks for the thread guys helped alot.

OK, simple question. This adpater looks like it's for speaker level outputs from the deck. What if you want to use RCAs from the deck...? Is there an adapter for that, or do you make your own using some Radio Shack RCA to wire converters? That's what I did for my Legend's Bose system to convert the pre-amp wires to RCAs for the sub.

Flybye

You would have to make your own adapter for the RCA jacks. I've never seen an adapter that converts from RCA to speaker wires.

Flybye

Honestly, they both look like they do the same thing! Both are 4 channel capable and both are adjustable, but it DOES recommened the $50 one for the Bose system. The Bose System works at about 2ohms. Maybe the 2nd one has better clarity. Did you ask Crotchfield?

This is the adapter to use for head units with 4.5V or higher RCA (line level) outputs.

P.I.E. (Precision Interface electronics)
Model: PDC-LOC4 to do all 4 speakers.

It is best when the aftermarket head unit has an adjustable subwoofer output so you can wire that to the bose tubes instead of using the rear speaker outputs.

Also, you will want a head unit with DSP, EQ, crossover and sub woofer control so you can fine tune your system.

Combine the above adapter with a typical Mazda wiring harness adapter, if you want to plug right into the stock harness.
Buy two harness adapters though, because you will need to borrow a contact from one and add it to the other, in order to connect the Amp Turn On lead.

The RCA method is the better way to go (versus speaker level) because you get a cleaner signal to the Bose amps and you get to utilize the line level subwoofer output to your bose tubes.
Just remember pre-out voltage must be 4.5V or higher.
This will limit your chouce of head-unts, but there are still several excellent models to choose from.
(Kenwood Excellon models for instance)

what is the voltage input for the Bose system anyways? Is it more than 4.5V?

Lunar7

I do not know the awnser to that.
I do know, that when using the diferential converter (PDC-LOC4), a 4V input will not give you enough volume.
4.5V will give you ample volume.
If you had 5-6 volts that would allow more volume and probably work even better.
Hope that helps.

ahhhh so someone tell me which adapter chose one someone!! hahah
