My mono block took a dump and I have my 4 channel that's powering my doors how do you wire my subs to the 4 channel for the lowest impedance I have 2 svc 4ohm subs. Does bridging lower draw or just cause extra heat?
Typical 4 channel amp can drive 4 ohms at bridge mode (1&2 or 3&4). Lower impidence is not going to work in bridge mode, except for very few multi channel amps that can drive lower impidence.
