Rockford Fosgate Punch 150a2 Car Amp wiring manual


Sub amps are pretty straight forward.....Hook up you rca cable....then all thats left is you positive (B+) that goes to your battery....the negative that you should hook to a good paint free bolt in your trunk and the remote wire which connects to your stereo.....

Im looking at this rockford fosgate p700-1bd amp brand new for $300 it comes with a birth sheet it says 750 rms on a 1ohm load. i cant find any reviews about it 225 rms x 1 @ 4-Ohms 450 rms x 1 @ 2-Ohms...


You can't go wrong with Rockford, in my opinion. Everything they make is well built and high quality. I personally have two Rockford p500-1bd amps hooked up to four 12 inch subs in my car and those amps make those subs slam. I have them wired down to 1 ohm and the specs say that they should be pushing 500 rms a piece at 1 ohm so that p700-1bd amp really packs a punch. Depending on what you're hooking up to that amp I would defenitely recommend it to you. - Ryan in Alaska

How many svc subs at 4ohm does it take to get this amp to 1ohm stable and can you reccomend a good sub combo for this amp whether it be dvc or svc


It depends if your sub is 4ohm svc, or 2ohm svc. 4ohm would take 4 subs wired in parallel, 2ohm would take 2 subs wired in parallel. But for a amp that big, subs that'll handle it are definitely gonna be dvc. I'd recommend 2 Orion 4ohm dvc hcca's. They come in either 15in or 12in. the 15s are louder if you have the space for them. As far as wiring goes, wire the voice coils on the subs in parallel to 2ohm per sub, then wire the 2 subs in parallel to 1ohm. Goodluck and congrats on the equipment, Orion is about as good as you can go for subs and amps. just be ready to lay down some dynamat cuz this system'll bloww your vehicle apart! good luck...

I have a rockford fosgate punch 150 and it will power a small 5 1/4" speaker, but doesn't seem to push my 15" subwoofer. I am reading 4ohms across the sub so I'm assuming that it is fine and that there is...


amp is way too small to power a 15 inch sub. But you should get some sound out of it, not silence. You can use a 9 volt battery to test your sub, if the sub pops when the 9 volt is placed across it's terminals then it's ok. If it does not pop then your sub may be bad, or the coil may be frozen. (It can still read 4 ohms if frozen). If your amp powers smaller speakers fine, you know it's not the amp. If the sub tests ok, then verify your connecting it properly to the amp's correct bridging terminals.

How do i hook them up to work for 2ohm's


Hello rcantu76,

If your CVR's are 2ohm (model Nr. 07CVR122), you connect the voice coils in series and then parallel both subs to the amp. If the subs are 4ohm (model Nr. 07CVR122), they cannot be wired to 2ohms. Your choices are 1ohm or 4ohms. According to Rockford-Fosgate's data on the P1000-1bd, it is stable at 1ohm.

To wire the 122's at 2ohms, you would connect the sub voice coils in series (jumper one positive to the other negative on each sub), and then connect the remaining positives and negatives to the amp.

To wire the 124's at 1ohm, you would connect all of the positives and all of the negatives together to the amp.

Hope this helps.

Need amp for 2 15 l7 4 0hm


Hello jasonjohnson,

There would be more amp choices if those L7's had the 2ohm voice coils, allowing you to series the coils and then run the subs parallel to the amp for a 2ohm load. As it is, you'll probably have to run them as either 1ohm and have limited amp choices, or as 4ohm and settle for a little less power.

An absolutely excellent amp to use at 4ohm would be the Alpine MRP-M1000. At Crutchfield this one is on sale for $347. For more power, and an amp stable to 1ohm, I would recommend the Rockford-Fosgate Punch 1000-1bd, a "factory refurbished" model is available at Crutchfield for $349.99. It's $700 new.

Both of these amps have adequate power for 2 L7's, but the RF will definitely be the better power choice. Both are also well respected names in mobile audio and the prices are reasonable.

If you have deeper pockets and want to push the subs really hard, a Rockford-Fosgate Punch 1500-1bd will put a full 750 watts RMS to each sub.

Hope this helps.

Sub hook ups


There's a lot more factors involved than that.
  • Power capability of the subs
  • Type/size of the sub box
  • Allotted space in the vehicle for the sub box
  • Voice coil impedance of the subs versus the capability of the amp
  • Etc.
