i got my new power aucoustik BAMF 2000 watt amp. i hooked it up to my old subs and they wont move! I have hooked up two amps in the past so i know the basics. I have no idea why my subs are not working. I got a new 4 gauge wiring kit. the amps power light comes on and everything. the only thing is the speaker wire is 18 gauge i think, but could that prevent the amp from working? the fuses are good thanks
