AMP WON'T WORK POWER SUPPLY?

Hi, My Rockford 300s amp was working fine (running a little hot , but still playing loud). Anyway stopped working yesterday. LEd will not light up, fuse is not blown, everything else checked, ulitmately I opened it up, and it looks like a couple of wires in the "big circle of wires" right behind the power supply, a few look burnt. I believe that may be the problem, but I'm not sure. Any suggestions. Thanks

That big coil of wires ytou described is the transformer for the switching power supply. Sounds like you over heated it and blew out the supply or the output section. From what you described you should take or send this unit into be serviced as there are no user serviceable parts in this unit except a fudse maybe and if thats blown theres more problems as thats there ( the fuse) just so the whole bloody thing dosent burn up your car! Good Luck

Rockford Fosgate P3002 stopped working


push down and up on your subs and see if they make a starching noise, if they do then they are blown. take a test light to the amp, on the power and the remote and see if it lights up. if it does then turn the amp down and with a small speaker plug it in to the speaker outs on the amp and see if it plays if not then your amp is bad.

I have a hifonics Zrx1200.2 amp. I am running 2 Rockford fosgate p3 12s with it. The specs on amp and subs match perfect. So I have everything wired correctly, it least I sureeee think so. Subs are dvc...


u could just not have enough battery power or the load on the amp is to much. if the amp is in stereo mode it should work but if it is in bridge mode the ohms would be to low .. best thing is to get a sub amp with a 1 ohm stable capacity.. and you amp should be at least one third more powerful than the subs..eg: if the 2 subs is 1000 w each the the amp should be 2500 rms and up to prevent the amp from maxing out and over heating etc.

Were is the fuse located on the punch 300s?


I just read all the information about this amp on crutchfield and never saw anything about a built in fuse or external fuse. I don't think it has one.

I have a rockford fosgate x7 amp and the fan stop working and a little while after playing it shut off what do you think


replace the fan in the amp, sounds like the amp is overheating and the cut off is kicking in... you can try the amp while not driving and the car parked, put a fan, like a desk fan where the amp is so it flows over the amp fins, and run the amp turn it up and let it work, see if it still shuts off after that, if so then it could be something internal nut sounds like it is the fan to me... and i have worked with many an amp and system in cars and trucks... hope this helps you

Quick question, amp problem


make sure you ground wires arent shared, meaning run each ground wire from each amp to its own grounding point

There are two LEDS. One on top and one on the end. Did both light up? If not, which one lit up?
