Amp stopped working. Help plz.

[Lil Webb 225]

I recently got my dads 2006 Nissan Frontier. Me and him installed four Polk audio 6 1/2" door speakers and put them on a old school punch 300s( gangsta a$$ amp btw). When I got it I installed my subwoofers and ran my amp and cap. When it was done I tested everything before I picked up but when turned the remote knob for the sub amp the highs amp killed. I checked the fuses and changed the fuse for punch amp just to be safe but no luck. This morning I pulled up to gas station I hit a bump and all the speakers came back on but when the back wheels hit the bump it cut back off. But all the connections are tight and no stray wires sticking out of the connectors. Can someone help me out maybe I'm overlooking something, I did the basic troubleshooting but should I maybe run punch amp off my cap too?

Thank you any help

If you went over a bump and your system came back on, that's your answer right there. You must have a loose connection somewhere. The extreme exception would be some type of relay or other mechanical device that has failed and the vibration from the bump made it work temporarily, but that is extremely rare. I would start by pushing in on all your connections to see if your sound comes back while playing at a lower volume level so you don't burn anything up.

The power, ground, and remote wire are snug I didn't yank on them but gave them a reasonable tug. Should I try to run it from my cap instead?

Sounds like you have loose connections like stated or you could also have a broken solder joint inside the amp itself.
