My last car had a 650W Rockford Fosgate system w/sub (from the factory). The stock stereo on my LT can't really compare to that, but I guess it's to be expected. It's not awful or anything, and it's nice that at least it has 6 speakers. I've been playing around with the EQ settings, and it's sounding pretty nice. Not gonna be blastin' bass and shakin' windows or anything, but that's not really my style anyway
The GM sub that can be added looks pretty cool, but hell, it's like a grand or something:(
