[s-cars] stereo upgrade

Fri Mar 2 01:27:20 EST 2007

I have the popping but not the ground problem.  Did the ground problem come
when you put the in line converter in?  The best ground I can find is the
wire that goes to the original head unit...it is a very good ground.

I am running a new alpine head unit to the stock amps and speakers through
the stock wiring using a fabricated connector.
The volume/gain and pop turn on problem was solved with an in-line converter
for about $25.
The problem I am having now is bad ground noise. I have tried grounding the
head unit directly to the chassis but no change.
I assume there is a bad ground in the harness somewhere for the three amps
in the stock "BOSE" system.
I had to piece back together the factory wiring since a previous owner had
cannibalized the stock common ground speaker wiring to use as speaker leads.
Has anyone had this bad ground noise problem with a new head and stock amps
and speakers? Maybe it is just my crapped out wiring.

Thanks,
Aaron Ryba

[ author ]                   In actuality, you can run Bose speakers with
after aftermarket amps,
provided they high end or 1 ohm stable amps. As for keeping the radio info
in the IC, good luck finding that unit, as those were Blaupunkt units and I
don't believe you can find any new Blaupunkt unit with the same interface.
If you were to find maybe an older aftermarket unit, it won't have any good
features that newer radios have. As for using an aftermarket headunit on
Bose, I use high/low convertors. If you try using the Metra RCA adapter kit
only, you'll get the pop noise when you change stations or modes in your
radio. You don't get that with the high/low convertors on speaker lead
inputs. I currently run an Alpine unit on stock Bose system in my 93 S4 with
high/low convertors, and I just finished running my 95 A6 Non-Bose, with
Alpine headunit direct to speakers on front and RCA to rear speaker (Active
system) with an installed Bose Avant subwoofer on high/low convertor on rear
speaker leads. System in the Avant sounds great. Almost as good as Audi Q7,
but with less bass since it has smaller speakers.
