[V8] planning a new stereo upgrade

Tue Dec 9 22:11:27 PST 2008

Before everyone goes marching out to match line levels... The output of 
a Bose head unit is NOT a simple line level left and right output of pos 
and neg. It is a blended output of left and right AND front to back that 
requires a specific 'decoupler' to match up to the individual amps. Even 
with the correct device the quality is not good. I've yet to hear one 
I've even liked for talk radio...
Added to this is the fact that the stock speakers are absolutely nothing 
to write home about - and the newest ones are 15 years old for a 93.
I like Bose - I've had 101s, 201s, 301s, 901s and currently have a set 
of AM5s at home. I have 2 V8s with perfectly working Bose systems and 
the system still sucks. The bass is way too high and muddy. You only 
start getting decent sound out of it when its cranked to nearly 
earsplitting levels with the bass dialed way back and the treble turned up.

Reality is the only 'right way' to do this is to chuck the ENTIRE 
system, bypass the wiring and run everything new with at least 14 guage 
wiring. Go with Infinity Kappa and/or MB Quart. Add a sub if you want, 
amps too. Drop kick the crappy diversity antenna system and if you don't 
have a factory electric rip out the analog cell antenna which is already 
useless and put a nice one in there.
Then select a decent head unit and call it a day.
