Question about Rockford Fosgate Punch 301S Car Audio Amplifier

1 Answer

Amp will not turn on

I as well, was just listening to some music and my long time working sub just stopped. I has a solid ground at the terminal and 12v from the battery and at the remote wire. I'm running it bridged into a 4 ohm load and not pushing the amp too hard. The light on the amp won't even turn on let alone any sound from the amp. It is totally dead. Has anyone else encountered this problem and found a solution? Thanks.

    When I said "terminal" I meant the terminal on the amplifier. All of these things check out. They both read between 13v and 14v.

You need to confirm that you have voltage at the amplifier.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

You may have touching speaker leads going into the amp. Make sure the tinsel is not touching across the speaker inputs on the amp. Also check your ground. It should be solidly connected to the vehicle chassis in a paint-free location. Finally, make sure there are no exposed speaker wires touching the vehicle chassis.

I cant hook up my amp


Hello cesar199064,

These are the steps you required to install your amp and subs:

1) Purchase an amp wiring kit with 2 or 1/0 gauge power and ground wires.
2) Decide on a location to mount the amp where it will get proper airflow and will not interfere with operation of the vehicle. Closer to the battery is better. Decide on the location and install the sub enclosures.
3) Locate a place on the metal body of the vehicle within about 3" of your amp for the ground. Connect the ground wire to the amp ground terminal and to BARE METAL on the vehicle.
4) Run power wire from battery positive (+) using one of the amp kit ring terminals through a 100A fuseholder to the amp positive terminal. DO NOT install the fuse yet.
5) Run a "remote" wire from the remote turn-on lead (usually blue or blue/white) of your dash mounted head unit to the amp turn-on terminal. Run a set of RCA cables from the preamp or subwoofer outputs on the head unit to the amp inputs.
6) Run speaker wire, preferably at least 12-gauge, from the amp output terminals to your subs.
7) Check all of your wiring. Make sure that no insulation was damaged or peeled off during the running process. Make sure there are no loose strands touching adjacent terminals or bare metal.
8) Use a multimeter set to read "ohms" and test from the negative battery post to the amp ground terminal. You should read "0".
9) Install the fuse.
10) Turn on your head unit and listen to those big Kickers thump.
11) Adjust the amp settings according to your manual.

The best place I've found for in depth information on audio installs is The Install Doctor. You'll find step-by-step procedures, color photos, wiring details, and even the tools required. I recommend that you begin with the "tech docs" link and read through some of the PDF documents.

Hope this helps.

Subwoofer works at high volume, doesnt work at low volume


You had the settings set incorrectly and overdrove it. The voice coil leads are burn't open. If you look at the little flexible braids by the terminals I'll bet they are black/brown and maybe even burn't in half. It's toast.
