Question about Rockford Fosgate P3001 Car Audio Amplifier

1 Answer

P3001 System work working fine but all of a sudden, my 3001 is not longer power my sub the way it used to. I still feel some bass coming out but something is wrong. Even with the gain all the way up, it is hardly 20% of what it used to be. Checked all the cables and everything seems to be fine. What do you think?

    Hi, Thanks for your reply.



    I had cleaned the ground wire attached to the chasis, however, did not sand the body of the car. There was a little rust there so I sanded it out and reconnected. I noticed that it got better but not completely.



    So, I then took out the ground wire from the amp side and noticed that there was this greenish dry powder on the copper end that connects to the amp. I used a wire brush and rubbed some of the powder off. There was still some left but when I reconnected, the sub is working much better. Not sure if it is 100% but there is definetly a huge difference.



    What do you think that powder is, should I replace the wire and or should I open the amp's terminal to clean that out too? And, is there a way to know if the amp/sub is working at 100%?



    Thanks in advance. I really would not have gone this far if it weren't for you.

Tighten very good the ground wire to your amp, then clean the metal where the ground attaches to the car chassis. Then tighten the ever lovin' bejesus out of the chassis ground. Yeah, I'm from the South :)
Good Luck!

My powered subwoofer no longer works through the receiver


if you have your front and centers set to 'small' you want your Bass out to be subwoofer only, and the rca jack labeled 'sub out' is the only place to connect your sub to if you want to control the frequencies with your reciever. I dont know the brand of your sub, or the inputs on the back of it to advise you where to connect, but it sounds like it worked for you at one time, but suddenly it does not

Is the p3001 bridageable?


The Punch P3001 is a 2 ohm stable monoblock amplifier. It therefore has only 1 channel. Not bridgeable.

Below are the specs off the rockford site.

  • Punch P3001 - 300 watt mono amplifier

    150x1 @ 4 ohms, 300x1 @ 2 ohms, 12dB/oct HP/AP/LP crossover variable 40-400Hz, RCA inputs, RCA pass thrus, cast aluminum heatsink, military spec PCB, and remote Punch Bass EQ with 0-18dB @ 45Hz. H 2.4" x W 11" x L 11.7"

  • If you are using your amplifier at a 4 ohm impedance then you will only have 150 Watt delivered to your woofer or woofers. If you are running your amplifier at a 2 Ohm load you will be recieving 300 Watt to them. This however will also draw more current to deliver this power.

    If you are certain that you can deliver the correct current to the amplifier and you are running a 4 Ohm configuartion. Then consult a Rockford delaer for a sub upgrade.

    Playing music for about 2hours and bass amp shuts down


    You have maxed out the amp! if your running one 4ga. pwr wire to all your amps, it's choking. Going to Wendy's buying a frosty and sucking it thru a straw!. Your amp is starving for more Voltage and current. That amps peak output is 1200w @ 1ohm, not too shabby! Now onto the next issue: Grounding!, just as important as power! Your amp MUST be grounded properly. Don't ground it to a seatbolt or side wall of the vehicle, go directly to the floor, hopefully less than 2-3ft tops. using the same gauge wire as power. If your power is longer than 12 feet, and in most cars it is, you loose alot of voltage and current flow to the amp the longer the run, the more you loose. That's just how DC power works. What's happening to your amp is it's working itself to death and creating massive amounts of heat. "enough to cook dinner" Run a 2ga or 1ot power wire to a distribution block at the amps. Wire in your other amps, then use the stiffening cap just for the sub amp. Not a cheap answer but it will solve most of your problem. Next, set the gain on the Sub amp NO HIGHER than 1 o'clock. Beyond this, and there's no help for it, there's no more gas pedal to push!. Enjoy your system but don't kill it! Hope this helps

    Sounds like your original and this sub have bad amps. The amp for the sub is not the same as the amp for the other speakers. The old unit has a dead amp and this new one is on the way out. (Pulling too much current on high bass)
