hey, im new to the forum and i have a problem with my subs/amp/deck


they worked fine for almost 2 years and then one day i turned the car on and music was playing all fine and dandy, and then it cut out for no reason and every once in a while i get a random bass hit thats completely unrelated to the music... even if i turn the music down low or shut the subs off (via the deck) it still gives a wierd bass hit every 30 seconds or so...

the only way to get it to stop is if i turn off the subs and hen shut the car off and turn the car back on and leave the subs off...

so ive been driving around with no bass for the last few weeks and its really starting to bug me.... any sugestions?
