ill try to descibe it the best i can..the sub is only outputting bass you can feel that its moving but its realy soft and doesnt move much at all.the normal speakers bounce more than it does lol.the speaker wire from the sub to the amp is roughly 2 metres and the power wire is still the same length (8m i think) because i havent cut it,the earth is bolted onto the front seat brackets as the amp is under the seat.all the power wire,ground and that is 8 gage.
I feel shamed because my mate has a smaller sub and smaller amp and his pumps..
thanks for any help.
