Sub + amp = 200? Thats kind of tight if you want quality with tight bass.
Heres what I got
Alpine Mrpf240 4CH i think 360 Watts from Panasonic HU. Speakers are Infinnity Kappas and my sub is a JL Audio 10W0
I think i got around 180 on the speakers 400 for amp and wiring and the free Sub was 100.
Its a decent system Plenty of SQ but for 200 dlls I dont think you'll go too far.
