I have a Buick Reatta and love high quality sound. My issue is one that may
people face while tring to keep a factory radio and improving sound. Any way
I want to find some one that is capable of getting rid of the bass roll off
of my factory radio brain. I do not care how it is done. Maybe remove the
factory amp and replace it with a decent aftermarket or just disable the bass
roll off. I just want to keep the treble and bass controls.

Anybody here willing to take on the project? I do have the delco prints for
the radio.

Back in 1977 I used a Pioneer tuner and built my own amplifiers...
bridged, to up the available power... for my Nissan 280Z. I still
have the drawings. If there's interest I'll post them.


Up to available power meaning until the ignition coughed?

Naaah! It was around a "true" 12 Watts (into 8 Ohms) per channel...
quite adequate in a small cab.

I am just
picturing you driving down some boulevard, in your 280Z, windows rolled
down, stereo on 10. Tchk .. tchk .. *BOOM* .. tchk .. tchk .. *BOOM* ...

Mostly classical in those days... you couldn't get '50's and '60's
rock 'n' roll on the radio then. Now you can.



You can probably easily break into the radio prior to the power amps
and basically get a line out function.


Or just use the regular speaker outputs,

Most radios today have single chip power amplifiers... distortion out
the wazoo :-(

spiff them up in frequency
response to your liking,

I don't know for sure what the OP means by "bass roll off"... maybe
tiny speakers. I cut out the original speakers in the Z and put in 6"
x 9" ovals.

then drive one of those monster amps. Like the
ones the kids use in their lowered Hondas with the mag wheels.

I'd like to find a "killer signal" for those... really aggravating to
stop at a traffic light and feel my car shaking to the beat of some
low-rider scum car :-(

I found that the really high screeching violins on one of the tracks
of the 2001 soundtrack album does a pretty good job. But you have to
crank it. Some good horn speakers could really help as well as a
couple hundred watts like they have.
