HEy i need help with my trucks sound system I got 2 Amplifiers that are 400RMS 2x 2ohs. And i just got 3 12" Subs 475RMS. I was look for a way to use the 2 Amplifiers with the 3 SUBS.
Is your amp bridgeable? If so you can combine the 2 channels into one and power one of the sub, and power the other 2 with your 2nd amp. Make sure you don't exceed the amp's ohm requirement. You can also power all 3 with one amp bridged (within the amp's ohm requirement).
your best bet, if these are all 4 ohm single coil subs, is to get a third amp and bridge one amp per sub. otherwise just use one amp for the subs, and one for your components
