Question about Rockford Fosgate Punch P2002 Car Audio Amplifier

1 Answer

Amp Issues Suddenly my subwoofers are not outputing much power. But when they are outputing, at decent volume but full at full bass settings, the subs knock rather than thump. sounded like the subs were blown, so i had a warrenty on the subs and exchanged them, reinstalled and the same problem is still there. i have triple checked the wiring, all fuses, even popped the lid of my amp to make sure i didn't smell any "dead electronic smells." off the amp i am running two infinity 10' subs, infinity product number w1052. but the set-up worked fine for a few years and now something went haywire. Help?! Back to discribing the sub output noise, it is okay under real low volumes of bass but when the speaker has a heavy load on it, it seems as if the speaker is making a popping sound.

Can i use my jensen jxp340 amp with my one 800watt 12" 4 ohm subwoofer?


Yes, technically you can, however you will be putting both your sub and your amp at risk. One of the worst things you can do to a sub is underpower it. The easiest way to explain it is n ot giving enough power to the sub leaves it starving for power. The motor structure ends up working too hard to try and move the cone properly and what happens is the sub will usually seize up rather than blowing out in the term you usually hear (ie, I had my system cranked up and I blew my subwoofer).

Secondly, in an attempt to get any real sound out of the under powered sub, you'll probably end up cranking the gain and bass boost on the amp which ends up overworking the amplifier quite a bit and can in turn lead to fried out amp chips, burnt up circuit boards etc.

Thirdly, by maxing the gain bass boost you're going to end sending a lot of distortion through your subwoofer in an attempt to get some decent bass. Distortion kills both subwoofers and speakers alike.

So to answer your question, yes you can hook up your subwoofer to that amp and yes, it will probably play for a while but I wouldn't recommend it. Look for a class d or mono block amp to push your sub as these will give you the most power and best heat dissipation. They are designed to push subwoofers specifically and you will get better sound and longer life out of your equipment. A good rule of thumb is look for an amp within 100-150 watts of both your RMS power handling and your Peak power. Remember, when it doubt, always go a little bigger on the amp side of the spectrum. It's easy to "tune down" an amp by having the gain and bass boost at a lower level (50%, 25% etc), than to turn 'em all the way up just to get some bass and end up prematurely blowing out your sub, amp or even worse, both.

NO BASS!!


1) Check the Subwoofer for continuity - At the subwoofer, one at a time, test the terminals for Continuity using your Digital Multi-Meter; if your DMM doesn't have a Continuity test, use the Resistance, or Ohms, test and check for Resistance in the Subwoofer Coil (be sure to disconnect the subwoofer wiring before performing these tests).
2) If they test out good, hook the wires back up and test the terminals at the terminal cup or at the Amp hookup if you didn’t use a terminal, don't hook it up to the amp yet. Sometimes the wiring inside the box can be a problem if it has come loose, or isn't making a great connection.
3) If you have a Sub or multiple Subs with Dual Voice Coils, or multiple Subs with Single Voice Coils, make sure your wiring is correct by checking here:
http://www.the12volt.com/caraudio/woofer_configurations.asp
4) Make sure there are no Hi-Pass filters, crossovers, or multi Channel switches enabled.
5) Replace your RCA cable/s with known working RCA cable/s from the Source/Head Unit to the Amplifier/s.
6) Check your Head Unit settings; make sure the Bass is turned up and/or the Subwoofer setting is turned On.
7) If you are still getting no or low output, try plugging in an MP3 player or CD player using a headphone to RCA adaptor and check for sound output. If there is still no or low output, your Amplifier outputs are probably burned out.

Bass cut off when volume is too high


When an amplifier shuts the Bass off that means its going into protection mode otherwise it will burn out the outputs. One way is to turn your gains down, Pioneer amps are not the best amps for bass out there, they are more for car speakers, I personally wont use a pioneer amp to run my subwoofers especially if they are hard driven subs like JL , Kicker Solo's and MTX subs. But for now just turn the gains down to 3/4 and that should help u, you can also install a fan to keep your amp cooler, if this never happened before in 5 yrs and now it does then that means your amp is just tired and the inside components are overheating easily, thats common with Pioneer and Sony amps.

Good luck buddy.

Only powers subwoofers when at high volume


Well, make sure that the output level on your head unit is up, and also try adjusting the gain NEVER EVER PUT IT ON FULL GAIN BECAUSE THAT WILL CLIP THE AMP AND MAY BLOW AMP AND/OR SUB!!!

Amp is on, but sub wont produce any bass


Make sure the subwoofer is set to low frequency, make sure subwoofer and bass are enabled on the headdeck. Make sure the gain is turned up on the amp, make sure the rcas haven't come out of the back of the head deck.

Legacy Amp 2600 watt HELP


Hello e_cody_e,

The settings you have will not break anything and may sound OK.

But they may not be optimum for getting the best bass from your system. The SubSonic setting filters out frequencies below the threshold of hearing allowing the amp to put more power into the frequencies that can be heard. So, it should be set to about the same frequency that your enclosure is tuned for or just a little lower. If your enclosure is tuned for 35Hz, then the subsonic should be close to maximum.

Similarily, the low pass sends all frequencies below the setting to the subs, (other than those blocked by the subsonic filter) and is commonly referred to as the "crossover" frequency. Typical crossover frequencies for subwoofers are 60Hz, 80Hz and 100Hz. For a ported enclosure, lower is probably better.

The phase shift should be set to the position that best synchronizes the bass with the music. Because of the additional wiring required for the subs, the signal to them is sometimes slightly delayed causing the bass to be "out-of-sync" with the rest of the music. The thump of the bass comes just a little sooner or later than expected. If the bass sounds out of phase, turn the phase shift on, otherwise leave it off.

The "gain" or level control allows you to match the amps input to your head units subwoofer output. The best setting is usually as high as possible without distortion. Set it by turning up the head unit volume to about 3/4 maximum and then advance the amp gain until your subs just begin to distort. Then back it off slightly.

These settings should allow your amp to put the most power into the frequencies that your subwoofers are designed for and hence produce the loudest and lowest bass.

Hope this helps.

Volfenhag zx-8400 amp and ZX-4712DVX subs


First of what you have should work great together....now the next thing is: does the bose system carry powered speakers if so the spliced speaker wires should be put onto a converter(a small box with RCA outputs) then you should make sure the levels in the little box is not set to full but 75%, if set to full you can be looking at distortion. Then they should set the amps to full range and see what you get.........oh and by the way you don't have to use that little controller(with the telephone wire) for the bass. You can control the bass with the frequency controllers on the amp or your head unit. And it's not a german thing trust me they come with nearly all amps now. These guys are full of ****. If you don't get the punch you want they should try bridging the amp for more of a punchy sound. Oh and you can use that decent sized box with the vent holes......that should work fine.

Is it good


If you are using a GM-7200 amp, it should sound great. Both the amp and the subs are rated at 800 watts so be careful not to overload the bass by turning them on full power. It is good practice to have a slightly lower watt amp than the subwoofers. If you can power your rear speakers from the amp, that would take away some power to prevent the subs from overloading. Overall, you should get a nice THUMP!!
