20 Most Recent Rockford Fosgate T20001 bd Car Audio Amplifier Questions & Answers

Disconnect your subs. Chk the impedance with an ohm meter. They should read apx 4 ohms or 8 depending on woofer. If they chk ok chk the remote turn on for voltage when system is on.

that is gonna be the place to start but you also want to check the pc board for burn damage, and test your capacitors. unless you are electronically savvy i would bring it in as you could cause more damage. doesn,t hurt to get an estimate, you can always take it home and do the repairs yourself if you feel up to it.

what about the remote terminal?

its blown send it in

If you're running the amp into a safe ohm load, it's likely that the amp is cutting out due to low voltage. You need to check the voltage with a multimeter connected directly across the terminals of the amp. If the voltage is dropping below ~10v, check the voltage across the main battery terminals. If the voltage is essentially the same at the amp and at the battery and it's dropping below ~10v, you need a larger alternator.

In most of Rockford's amps, the low voltage detection is connected to the remote input. If the remote voltage is too low and they use the same circuit on this amp, it could trigger the protection circuit.

 

Disconnect the head unit's remote from the amp. Use a fuse holder with a 3 amp fuse to jump between the B+ connection and the remote terminal of the amp. If the amp powers up, the head unit's remote output may be defective. If it blows the fuse, the remote input or part of the power supply is damaged. Do not try it with an unfused jumper.

Recheck wining setup for proper connection

Internal or external short. Disconnect everything but power, does it still blow? If it does, you need to take it in for repair..

Hello a_brake11,

The P325.1 is relatively small to power a pair of P3's. You'll only get 325 watts RMS at 2 ohms (162.5 watts per sub). The P3's power range is from 100-500 watts, so they will work, but don't expect them to be really loud.

For best power, your subs should be wired with the voice coils in series and then the 2 subs paralleled to the amp resulting in a 2 ohm load.

Hope this helps.

First off will the fastener turn ? If not try using a bit of wd-40 and letting it "soak" for a little while . Also be sure you are using a good proper sized Phillips screwdriver . If the fastener still won't turn try using a can of "computer duster " inverted so the liquid comes out , note this will be well below zero degrees , and freeze the screw head , then try turning . If the fastener is stripped and the ttol slips you will have to remove the amp cover and grip it with a pair of vise grips ,pliers or a flat blade screw driver .

You may not have enough ground connection or your are running too much power for your amp

Yes. Wire the two 2 Ohm speakers in series and connect them to one channel. Connect the 4 Ohm speaker into the other channel. This will give you a balanced 4 Ohm load on each channel.

In series, yes

i have a punch 45 but i'm missing the speaker wire connector.... were do i go to get one...

Please be more specific. RF doesn’t share schematics

Check fuses first

You may have a blown speaker. I would check for that.

IF you are looking for a schematic diagram on the amp, you wont find it. IF you need the connection information you can look on their site, There is a repair video on that unit attached . Rockford Fosgate Car Stereo Amp Repair
