Hello guys. I'm just another audio fanatic trying to look see whats the best route for my goals. I am definitely looking and wanting SQ, I'm just not sure about which brands work, and what brands to stay away from. Also, I'm looking into upgrade my amp, but I guess overall, looking for a system thats not too taxing on the electrical system. Looking at the FI Q's, seem to be very tempting. My vehicle is an 01 tahoe.. Currently, I have a beginners system... Kappa Inifinity Comps w/ jl 4 channel, 2 punch HE's in a sealed box(dont flame, I did't know any better) w/ old pioneer amp, and a poineer h/u... Any advice or suggestions is greatly appreciated... Thanks..
