my amp was cutting out and i assumed it was because it was overheating(alpine v-12 4 channel(150 per channel). so i went out and bought the new sony 1200 watt xplode amp and its doing the same thing. i got the amp running to two brand new rockford fosgate P1 12 inch subs. is overheating the problem and what can i do about it?

its not overheating. first of all are you using the correct ga. wire? for a 1200 watt amp i recomend 4ga. if you are you using that ga. you might wanna look into a cap for your system . you might have alot of resistance using thin power wires

Should also check the speaker load on the amp if it can handle 1, 2 ohm etc

Do it right the first time or don't do it at all.

The way you have the subs wired could be the cause. Have you checked the ground wire to make sure it is free of rust or paint? There could be other causes also. Does it get "hot" to the touch?

Are the subs 8ohm or 4ohm? Single or Dual Voice coils?

Don't bridge it. Run a wire from each channel to each speaker, + to +,- to -.

Most amp cannot load 2ohm resistance when tey are bridge. so you have to connect one wire for each woofer. i think tha is you problem try it and post reply.

Good Luck
