Question about Rockford Fosgate Punch 300S Car Audio Amplifier

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

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.

You probably have too much hooked up for the size of your power supply which is presumably a small car battery. You either need to get:

A) New, better bigger battery.
B) Capacitor in series with battery.
C) Both of the above.

If it is the power supply use IRF3205 and change the gate resistors to 47 ohm. Also replace the 4 power supply drivers.

hi, some car amps need a high current remote supply to turn on. first make sure that you are using the proper gauge b+ and gnd cable for this particular rockford amp. then try switching the remtote turn on to this amp thru a simple Relay.(use the remote supply from your headunit as a trigger for the relay). do these connections without connecting any spks or rca line inputs. once amp is switching on then connect all other cables. OR lastly check the main fuse on the RF amp?? cheers
