Stereo & Electronics - Speaker rewire question
03-25-2012, 10:05 PM
So I am rewiring my speakers to the head unit to bypass the bose amp, so they do not distort. I cannot figure out where to wire the speakers at the head unit harness. So any directions or install knowledge please help me out.
Also I tried running the wires through doors and the wires did not want to go through the accordian, so I am moving them into the sail panel. Any tip on how to get them through tried with the coat hanger, it just to tight of fit.

This is for the 94 and it is a 3 speaker bose stereo. What wires do I splice the new speaker wire into.

There is no "Bose amp"... at least not as a single device. The Bose head unit puts out low-level, high impedance signal to each of the three or five speakers (depending on model) which each have individual amps attached. Also, the Bose system uses common ground rather than the floating ground found on the majority of car systems.
Just rewiring won't do you any good - partly because the HU doesn't produce speaker-level (amplified) output but mainly because your new wires would still be connecting to the Bose amps at each speaker so you haven't eliminated anything.

I have an aftermarket hu , when i would turn the volume past half way it would distort.

That's exactly because you have an aftermarket head unit. The HU is providing speaker-level output to individual amps that expect low-level (pre-amp) input. As you turn up the volume you very quickly reach a level that the amps can't handle. You probably also notice the volume goes up very quickly with only small changes of the volume knob.
Get yourself a PAC OEM1 adapter (or equivalent) to properly match the head unit output to the Bose system and your problem should go away - if you haven't already damaged the speakers.
BTW, who told you that you could just plug in an aftermarket HU to a Bose system? I hope it wasn't somebody on this forum.

no one, it came installed when I bought it
I did not use the new speakers much and kept them turned down because they distorted. Under probably 2weeks of use, So do you think the speakers are ok?
WhiteBird00, I was looking at the description of what the PAC OEM1 does and was wondering. Since he has an aftermarket headunit couldn't he use the aftermarket headunit's RCA pre-out instead (if it has them)? Or would that not work?

you can bypass an oem1 altogther and use preouts on the radio if you splice in rca's

how would I do this?

Also I was saying for rewiring, new wire all together from the speakers directly to the head unit, bypassing the bose equip. Wouldnt that work? Splicing RCA's meaning get some rca wires, then cuting them about a couple inches back and conjoing the wires to neg and positive?
I will hold off on buying the pac oem for one more day. Until I figure out for sure.

Yes, you can use the pre-amp (RCA) output of an aftermarket HU to power the Bose speaker/amp combinations although it's not ideal. The OEM1 is basically an adjustable line out converter. It's the adjustability that makes it so useful for matching aftermarket head units to OEM amplified systems.

Well I ordered the pac-oem
