I have a 4 channel amp, and all i have are 2 subwoofers, how do you bridge that to get the most watts out of it as you can( its pointless to just use 2 channels of a 4 channel amp right?) and do you bridge it all together or bride 2 channels together twice(that probably sounds really confusing but i don't know how else to put it)
ok you have 4 channel's right! you take the front two channel"s and bridge them to one sub then you take the rear two channel's and bridge them to one sub when you do this you have to make sure that your amp can handle the impedence loads(ohms)
