Amp won't turn on after getting bumped around

[ckunke002]

I had to pull my sub box out of my car to fix some wiring inside the box. My amps are screwed into the side of the box, but due to size restrictions only 2 corners of the sub amp are screwed in so it can rattle around if shaken. It got bounced around a bit from all of the work and now when i plugged my amps back into my system and fired it up, the other amp reluctantly started up but the bass amp won't start up at all. This is the first time it's ever done this since I bought it about a year ago.

I don't know the first thing about amps, or what I would look for inside one. I have a few car audio stores around me including the big guys like Car Toys and Best Buy, which I usually don't like to go to..but if that's what it comes to I will.

Any advice highly appreciated. Need some direction here.

For the record, the amp is a Boston 500m.

BTW the amp was bought under a non authorized dealer (ebay) and is not under warranty.

Have you tested the voltage at the amp terminals? Is it getting power to it? Check your grounds also. Do you have the remote turn-on lead properly connected both at the amp and head unit, and is that giving sufficient voltage?

How much voltage is the remote lead supposed to be giving?

sounds like something came loose, but hopefully not.
