I got a new sound system (a sub, a amp, a capacitor, 4 gauge amp kit, stock head unit, all of which makes for a sound system that bumps hard as hell), and I don't know if its just me, but my car seems faster. Like its really jolty, i barely touch tha accerlarator and it wants to zoom zoom. And actually up top (6-7k rpms) it seems to be slower. How much of a impact either negative or positive does a sound system have on ur car's performance? My it does weigh down my trunk quite a bit, but nevertheless the car seems more jumpy. And my friend's type-s has a sound system and he jus has an intake, but he is a lot faster than all the other type-s's? What's the deal?
