Do they sell amps with only on port?
thanks

well when i said the bridge head units part i dont know how, because from all the head units i played with the have 4 speaker wires front right front left rear right rear left, and u CAN power a sub with those, but they are generally made for speakers, and im not really sure exactly how much an amp would cost to make 300rms, but for the most people 300rmsis enough
and yea the amp i had was 150 x 2 at 4 ohms, it was made for speakers but since it could power my old subs then i just used it when it says x 2 there are 2 channels most of the 2 channels can be bridged into a mono channel usually taking a positive from one channel and a negative from the other channel, my friend is actually bridging his 4 channel amp and it makes 200 rms x 2 at 4 ohm
i dont know why but multi channel amps usually cost less than the mono amps, i think because the mono amps can push more power, and they are ment for subwoofers
