Make sure you have good solid connections on your power and ground wires. Make sure the ground wire is touching bare metal if it is grounded to the chassis.

google the brand and model number and then look for owner manual online. Should be something there or at the Kenwoodwebsite on it. Ask tech support

Bad Ground

Or

Good Luck!

make sure that you have a good ground, make sure you have the right amp turn on wire, and your power wire is fused, best solution is to have it professionally installed! Amp install is very basic if you are having a hard time with that, I wouldn't attempt to try it or have one of your buddies install it! FRIENDS DONT LET FRIENDS INSTALL!

Check your wired connections going from your amplifier to your sub-woofers.

Could be your RCA's? Make sure theyre plugged in properly behind the head unit..

REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL DOES NOT POWER UP, VERIFY THAT THE POSITIVE AND ESPECIALLY THE GROUND CONNECTIONS, ALONG WITH THE REMOTE CONNECTIONS ARE 100%, THEN TRY AGAIN. IF STILL NOT POWERED UP, MEASURE THE REMOTE WIRE VOLTAGE TO INSURE THAT IT IS NOT LOWER THAN 11 VOLTS. IF YOU CANNOT MEASURE IT, THEN DISCONNECT THE REMOTE LEAD FROM THE AMPLIFIER AND TEMPORARILY INSTALL A JUMPER WIRE FROM THE POSITIVE POWER TERMINAL TO THE AMPS REMOTE TERMINAL WHICH WILL FORCE IT TO TURN ON. IF IS STILL DOES NOT POWER UP, THEN IT WILL HAVE TO BE SERVICED. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V
