i need help with my system

[hitman490]

i have 2 10 inch Kenwood subs p-w1000 hooked up to a Kenwood Kac-7205 1000watt max amp. im using 8 gauge wiring, with an alpine radio. while i listen to subs they are really loud sometimes and other times the bass just cuts off and its like at half and it will stay there for like 10 min or so and come back to full power. it cuts in and out like that all the time. does anyone know what is wrong? do i need a new amp or what?

Double check your wiring. A bad ground or loose RCAs come to mind...

8G wire may be the problem...but a loose wire or RCA as mentioned seems alot more likely...

but the KAC series amp that you have:

RMS Power Output @ 4 ohms (Watts x Channels) 170 x 2

Peak Power Output (Watts x Channels) 500 x 2

Power @ 2 Ohms (Watts x Channels) 250 x 2

Bridged Power 4 ohms only!!! (Watts x Channels) 500 x 1

your subs should be single 8 ohm iirc been awhile since I sold KW stuff...so wired to 4 ohms you should be fine but those amps are very notorious for over heating when bridged....if you had the single 4 ohm subs run 1 to each channel and it helps but you need to check you wiring and the amp/sub configuration as well

test the subs coils ect...
