20 Most Recent Rockford Fosgate Punch P2002 Car Audio Amplifier Questions & Answers


this amplifier is a 2 channel 50watts rms per channel and would not really be powerful enough to drive a subwoofer of any substance for car use, however , bridging it would give you 200watt rms into 4 OHMS but your subwoofer would have to be a single 4 OHM voice coil. Best you use this amplifier to drive a pair of speakers.
Hope this helps. let me know if I can further assist you

If all of your wiring is right, then that's a protection circuit telling you it's time to have your unit serviced by an authorized service center. Sorry for the bad news.

It sounds like you either blew a fuse, or you cooked your amp. The fuse on the P200.2 amp is a 30A fuse, and it sits right next to the power, ground, and remote wire connections on the end. Pull the fuse out and see if it's blown. You should also check any other fuses that you have in the car before the amp.

make sure the ohms add up from the 6x9's to the amp it sounds like theohms are to low

1) Make sure a bridged load of no less than 4 ohms is applied.
2) make sure both the left & right channels are working.

Do you have the amp bridged first off? if you do unbridge it. Next,

1) Turn all the settings all the way down on the amp.
2) Turn your bass on the radio into the negatives (-2 or-3)
3) Turn the volume up to the point where your highs start to not sound good, then turn them down just enough to where they sound good again.
4) Turn your crossover to about half if your box is ported, or three Fiths if its sealed.
5) Raise your gain slowly untill either the volume doesn't get any higher or you hear the subs start to sound funny. Now turn it down just a hair.
6) Turn your crossover up a hair then down a hair and see what happens, if it gets a touch louder with out distortion then leave it. If it losses clarity then place it back to where it was.
7) Listen to a couple songs you know well and stand in front of your subs at volume to be sure theres no distortion.

You should be good at this point let me know if you need something else.

Hello tejano71, I would suggest that you check your grounding and if possible run an extra ground from the battery ground just to make sure. Then I would use an DC line voltage filter between the power supply and the AMPs. If this does not work. You may have an issue inside of the fosgate AMPs. To troublehoot these you will need a voltmeter (set to the AC setting), audio tone generator (multiple settings from 20Hz to 20 Khz), two dummy speaker loads (set to proper impedance and wattage), and an oscilloscope (to see if clipping is occuring). After you have these items, connect the dummy loads to the AMPs and then connect the ground wire to the AMPs, and connect the power supply to the Amplifiers. Put one of the oscilloscope leads across one of the dummy loads and the other oscilloscope lead across the other dummy load. at this point connect the Audio Frequency Generator and set it to 20Hz and increase it to 60Hz as you also increase volume at each frequency looking at the oscilloscope for any signs of clipping continue to increase as you get higher in frequency. You should see very little clipping. If clipping is seen the actual unit may have a voltage regulator problems. If the unit has voltage regulation problems, I would suggest that you take the unit to a repair shop for further investigation, I have repaired quite a few of these units and for the most part regulation on these items sometimes can go bad with very little warning. Let me know if this solves your problem, or at least points you in the right direction. Thank you, Shuttle83

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 are driving it too hard. If continued, the amp will go into protect mode to save you from yourself.

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.

Please be more specific. RF doesn’t share schematics

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
