Bass Boost Gain Mod works in G8

How sweet. Now I can live with the stereo. The sub-amp is in the trunk next to the battery. remove all the covers, slide fingers below amp and feel for bias control and give it a turn. I am happy now.

Taken with Blackberry phone camera. Now I am off to get sunroof installed.

Bass Mod

vhato: Nice work! This is perfect. I planned on keeping my stock head unit and amps. If I was going to replace anything, it would be some of the speakers. Like 6x9's and 3 1/4 ones.

Thanks again, great find!

In another thread here, a GTO guy said how they do it. So I hoped the sub-amp was the same.

It ain't perfect. Country, Pop, Rock all sound MUCH better. However, Rap music doesn't. The Deepest Bass, sounds overdriven. Either the amp can't push it, the subwoofers can't take it or both. It is good enough for me to not spend any money doing anything about it though.

Thanks, it is gain control, my mistake.

I dunno what that amp is connected to in any detail. Rear door speakers sound the same so I assume is was just for the woofers. I could be wrong.

Reminds me of my Bonneville, except they were nice enough to put a sliding knob on the dash by the radio. It controls just the woofers.

Sorry it was a little off topic. Just trying to relate with my own experience...

subs in the rear of the G8 should be the same as the GTO's? trying to remember if the GTO's were 6 or 8"

i'd say the amp would be very similar too

I'm a bit lost. Does this simply up the amount of bass the system puts out?

It's the gain control which will increase the amplitude of the signal going to the speakers.

I am not even an audio prosumer, but based on what I hear...yes. It only sends more power to the two sub woofers.
