Amp cuts out, whats up?

[Shotty]

I've got a PPI Sedona roughly 7 years old runs at about 330 rms bridged and have it hooked to a single 12" sub at 4ohms in a regular truck cab. It has always run smoothly and strong but recently has been cutting out at about 70% power push. I turn the volume down and it resumes. It still bangs descent, but I'm obviously bumming. I have some skills at soldering on these these things; anyone have any clues or should I retire it?

I work at Best Buy car audio department. If I had a customer walk up to me with your same problems I would recommend a capacitor.

I've run the same amp for 5 years without a capacitor, I couldn't imagine it suddenly needing one (I've changed alternators within the past year too.) Truck amps generally push a pretty strong load. Maybe I spilled some beer on it or something.

You're retarded.

Where do you have the gain set at?

Gain is about 2/3rds. Like I said amp worked well for years, I tried a different sub same response. I tried new power wires, ground. Acts the same truck on or off, capacitor has nothing to do with it, not short of voltage/amperage. thanks

thats why you work at best buy. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

well its a long shot but it might be the rca's. Have you changed hu. Some people taht use the factory amp with the Alpine have had to run 10gauge power wire to the hu. I always run my internal amp off so I never had that issue.

you definately dont want a cap, all this will do will put a draw on your cars electrical system, and then it probably won fix your cutting out problem, i would try RCA's like green machine said, check all of your connections, and then i would say look at the internal components of the amp
