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!

Amp burned out but fuses still good?


this is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....

check and make sure all powers (12v) and remote ground are were they should be then check signal outputs is in the right spot comeing from (THE Radio) to THE AMP imputs.THEN CHECK ALL OF THEM AGAIN. if thats not it you will have to bring it to someone like me and be charged around $30 an hour to fix.

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

What Hz do i use


The best way to set up an amp is to start with everything on 0 Turn your gain all the way off, then turn the stereo up as loud as u would normally listen to it. With the stereo on, slowly turn the gain up until it sounds the way you want it. As for the Hz settings, for a sub you should have the crossover set to lpf, and the z knob adjusts what frequency your sub will play. Since you have a 10" sub, I wouldn't put it much below 125, because tens can't produce ultra low bass and it could damage the sub. Hope his helps :)

Subs fading out briefly but speakers working fine


Holy mackerel you have a ton of power i bet that ****** is loudddddd-sounds like your charging system isnt quite keeping up with the amount of current draw that your amps can pull.Upgrade your alternator and look into a dual battery system using an isolator-that way your alt will charge both batteries but your amps will only pull off the one battery-you can look online into how to set that up its not that hard for someone that has managed to install the gear that you already have- Some folks if not most would encourage you to get some sort of capacitor to store power blahblahblah-BUT a dual battery system has waaaaayyyy more storage capacity than a capacitor does-check out the pro competitors online they arent using capacitors to run their stuff they use banks and banks of batteries to get their power-brother you need more juice

Amp clickin in and out


Had a similar problem, mine was a power problem.
Power meaning voltage.
Those big bass speakers draw lots of power. My original alternator couldn't keep up.

Question: Do your headlights dim in rhythm to the bass hits?

If so, your sound system wants more power than your vehicle is producing.

My first solution was a high output alternator. It worked great.

Then I added another amp. Not great anymore.

My second solution was to tie in a large capacitor to the amps power supply. (These a big (1 farad), about the size of a Pringles can)

Your amps power consumption is not uniform. Each time your amp punches the bass, it draws extra power. If that power isn't available, it starves and shuts down (if only for a second) then restarts.

The higher the gain, especially using a low pass filter, the more power needed for each thump. Thats why when you turn the bass down, you can get higher volume from the rest of the system.

How a capacitor can help (simply put):
In this application, the capacitor acts like an auxiliary battery, smoothing out power fluxuations. The capacitor builds up its charge literally between bass hits when power demand is low. Then releases it's charge when the demand is high. Think of it as an on-demand power boost.

Hope this helped

Is the master/slave switch set to master? Have you tried feeding the signal into a different amp to make sure that there is signal reaching the amp?
