no bass from subs

[spencerS 10+ year member]

what could cause this? everything is hooked up fine was working fine for about a week, sub looks ok no burn marks on the spider. also the power is on on the amp. when i turn on the deck the bass plays for about 5sec. then it bumps and the bass goes off. does anybody know what could have caused this?

any info woould be greatly appreciated.

thanks

Perhaps your amp is going into protection mode due to too high a gain setting? Why not try putting it to a minimum then slowly start working from there?//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif At least that's how I sorted out my mistake...

Same thing happened to me... amp would turn on for a second or two then turn off. Make sure it is property grounded. Try putting it to a different grounding spot.

Sounds like grounding problem indeed. Perhaps you should also check your amp's Ohm driving capability. You could be running your subs at lower impedance that amp can handle and jumps into protection mode.
