Everytime I get in the "family truckster" I'm a little disappointed... Most new GM vehicles have "pretty good" stock bass... this one however doesn't have any punch. (It's new to us and I rarely drive it, let alone by myself,) So really haven't given it a workout. But the bass is set higher and is really lacking. It has the 8 speaker premier package with DVD for the young'uns. She won't stand for a HU, amp, and speaker upgrade, and anything I install will have to be compatible with the entertainment pkg. w/steering wheel controls. I've always installed my own sh*t, and recently re-did my system in my summer ride. I havent really had much luck in the past with those high-to-low pass converters that you gotta use for a system without rca's. Q. Can I hook up a small amp and sub that will not disappoint, maybe a couple 6.5's or one 8, and not hack into my wife's "new" ride???
