my system worked the other day, wont now.

so the other day i bought 2 10 inch xplods, a box, all the wiring, and an amp. my friend tony came over and put it all in, and it worked all day. the next day comes along and first my car wouldnt start until i unconnected the power wire, and now that it starts with the wire on the system WILL NOT work. all of the wiring is right and there are no loose connections, the amp is getting power. the subs just dont want to work, someome please help me, im starting to get fed up with it.

this is all in a 92 oldsmobile eighty-eight. the amp is a 1200 watt red top. i know someone on here can help me!

what sort of equipment do u have? Do u have a DMM? or some other way of testing for power? test light? Where was the main power cable from the amp hooked up to?

If all of the wiring is right and there are no loose connections then either your subs are blown, your amp is dead, or your head unit is fried.Kevin Pierson
