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.

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

No sub woofer output or very little


Your sub amplifier is detecting an overdrive condition and reducing volume to prevent the output stage from burning up. When reduced volume doesn't work, output is cut completely for 10 minutes until things have cooled down.

Why is my deck not controlling my subwoofer level?


If your Sony receiver has a separate sub output, it probably has a fixed level for application to a powered sub. Your mono amp can only boost the fixed signal level it receives from your receiver. The receiver can't drive that mono amp harder

My sony STR-DE475 has no bass. The bass just went out after running it for 6 hours.


Either the subwoofer speaker or its amplifier failed - they couldn't handle the extended use. Simple test to find out which: put the volume really low, connect another subwoofer (or a large normal speaker) to the bass output on the receiver and play some music. If you get sound then the original subwoofer is faulty, just get a new one. If you don't get sound then the amplifier for the subwoofer channel has failed. You could replace it yourself if you have enough electronics repair experience, otherwise it will be cheaper to just get another good sh low end receiver from a site like Ebay.

I am looking for a replacement sub amplifier,


Or you could just write of the built-in amp, disconnect the sub from it and run the driver's leads outside the box, buy any decent amp, connect it to the LFE feed for inout and the bass driver for output and carry on.

That's what I did when a second copy of a powered sub died the same way the first one did.

When my RCAs are hooked up to my amp, my subs start hitting without any volume turned on


1. Check Grounding system (Player and Power Amp).
2. Ensure your RCA cable is OK
3. You might adjust volume or bass volume on power amp to maximum, just set all to 50% while you are tuning.

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!!!

Can I use front preouts for subwoofer?


First, you have to have a self-powered subwoofer (or two) with this reciver. That means the sub has its own amplifier. These are usually capable of accepting either Line Level (RCA) input or direct L and R amplifier channel speaker wires from your receiver from which it will react only to frequencies in its range. It doesn't actually use any if the power from your receiver's amp.

That is why you can extend your front speakers from the sub. Again, understand this - it is not playing any part in amplifying them. The amps in your receiver are just passing through it.

Setting your speaker 'Type' definition to Large will tell your receiver that they are capable of real bass (as opposed to small satellites) but won't necessarily steal anything from the subs. Set your LFE/Bass Out setting to Both if your front speakers are capable of handling real bass. Why would you want to deny them bass if they can handle it?

This part is confusing "If I can get the sub working on taking the lows out of the front speakers if I set them to large on the receiver then that is one thing less to send to the other sub on the LFE channel". The crossover feature allows you to define what bass goes to the sub. You would use the various points to smooth out the transition between your sub and the rest. Your quote of 47hz spec for something doesn't suggest your other speakers are great bass reproducers. One needs to see the +- db spec with less than x% distortion for that number make any sense.

Your receiver has two RCA Subwoofer Outputs but I'm sure they get the exact same level. If you're having trouble matching two different subs doesn't at least one of them have an adjustment for volume? Or maybe you could use physical positioning to adjust their comparative volume.

Very low ouput from subwoofer preout


The problem was that some subwoofers (inluding my velodyne model) cannot process the LFE signals through the line level inputs on its amps, so the other way to run your subwoofer is to run the front left and right speaker outputs from your receiver to the speaker-level inputs on your sub, and then plug your front and left speakers into the soeaker level outputs on the sub. you have to set the onkyo receiver to "Subwoofer: No". that way the LFE signals are sent through the front speaker channels and you will get the same BASS output as if using the line-level input. O So yes it does require a bit more speaker cable, but it works fine now.
