Could anyone recommend a good system? Like the Amp, Subs, Wiring Kit, Etc. Etc. I was looking at getting (2) MTX Subs and then a dual box to hold them but I'm not sure on the Amp size and stuff. Do you have any other recommendations? I'm not wanting to spend a whole lot of money but I want it to sound good. I have a DUAL head unit with rca outputs for an amp. Thanks!
