4 channel amp is the problem. You need a mono or 2 channel. Stay way from boss, legacy, pyramid, crunch GPV, lanzar (cheap stuff).

What sub is it and what ohm voice coils does it have

M4 audio, 4 ohm

is it single 4 ohm or dual 4 ohm and how do you have it wired to your amp.

Your not gonna get full power from a 4 channel.

Too low of impedance is why. You really need a mono or 2 channel amp. 4 channel is for mids/highs

alright, what about a 500 or 600 watt 2 chan?

What kind of box? What kind of Vehicle? What is the ohm load of the sub you are using? Are you talking about peak watts or rms watts? There is a big difference and that alone is most likely your problem. That 4ch is prob putting out 30-40wrms per channel and you are trying to run an unstable ohm load to the amp. I see noobs trying to do this all the time //content.invisioncic.com/y282845/emoticons/banghead.gif.8606515f668c74f6de0281deb475b6fd.gif
