for good SQL u will want a nice sc player with 3 sets of pre outs and around 4+volts per pre out...... for speakers get a set of components, put the bigest onces u can in or afford in, run them off a small clean amp, for ideal sound imaging u only want fron speakers...... not subs get a pair of 12" subs, and and nice class d amp...........
i am runnig 2 12" BA inhumans ans a PH-D2 and am hitting 153 and they will keep up to any other sub in the sq department. i have a shitty kewood deck, and no speakers right now(cant afford them) i comepete in street 1-2 with that set up and do very well........
hope this helps........ email me at
crsicpash@hotmail.com if u want anymore info on BA subs
