Question about Car Audio & Video
The problem is the Kenwood isn't stable to 2 ohms and that's why is causing the thermal cutoff to avoid smoking your amp. From the 3 subs and 2.66 load I'm assuming the 3 12's are 8ohms each? The only cheap solution is for you to run them at the 6ohms (series/parallel). The correct way to do it would be purchase an amp that is stable to 2 ohms in mono mode or to get different ohm subs. You can only drop the load to 4 ohms mono if keeping the amp and you will need 3 dual 6ohm voice coil subs to run at 4ohms mono. When you are putting a system together you always have to consider the ohms before buying the speakers and amp otherwise you end up having to settle for whatever configuration you have with what your got. Most people with cheaper amps it just gets fried from overheating and there is no shut down. Also if the volts drop below 9 the amp will not have enough to run and will shut off. You car should never drop this low with the motor running. 1800 watts is not possible to run with a stock alternator. The rule of thumb is every 1000 watts requires 100am alternator so 1800 watts reguires 180amp alternator (just for the system) and then whatever your car requires to run as well. Multiple batteries and capacitors are required for the sytem to perform properly otherwise you will be going through alternators very quickly.
