i wanna put a nice sounding system in a wrx when i get one this spring/summer. i am looking at the 10w7s by JL audio. would want 2 of those. i know you can hook it up to a stock radio but will it affect the quality of subs alot? i will also be running a equlaizer so idk. Also... what amp should i run, i only wanna run 1 amp. its a 3ohm single voice coil sub. i was told to get a 1000/1 jl audio amp . but thats alot of cash there for 2 subs and that amp.
