ok i recently had problems with my bass sound so i figured there might be a short on one of my wires...

all the wires were good and i found out that my amp is having problems..
i would get no bass at all and when i give it a little tap it works again...then turn off then hit some more turn on..repeat..

if i had the money i would like to get a whole new setup of the subs but really short on money these days..especially when i have two speeding tickets i need to pay..-.-;; 65-84($390 including school and $40 for the school) 55-81(dont know yet...)

i just would like to buy a pretty decent amp that works better than the previous one and that wont blow out my speakers and small enough to fit in the backseat where in belongs.. any suggestions? THank You.
