Best amp for my Rockford 15 subs
David P on Dec 8, 2016
I chose this because of the RF name, 1200w, and low price.
Paul B on Nov 26, 2016
Been using fosgate components for 30 years. Always
Satisfied with performance. Very reliable.

I am hoping to get these with 2 p3 12s will my car battery be able to power it if i don't push them hard all the time, or will i need to get a additional battery?

Best Answer: If you do not have a very "beefy" battery then you may need either another or a Capacitor. with extras the size can be as big as you want for your budget but if you do not have either then your amp WILL make your headlights dim and electronic dim if it is turned up too high. I had a 3 Farad capacitor with my 2 p3 d-4's and the amp and I still managed to make my headlights go dim. Just make sure to remember that you get what you pay for in the car audio world and if you buy a high capacity cheap capacitor it may end up doing very little for your problem.

Does the Rockford Fosgate R1200 prime amplifier come with the pictured remote bass controller?
Scott p on Mar 25, 2015
Best Answer: Yes. It is wired though, it comes with a long cord, long enough to reach from the trunk to the dash.

will this push my 2 kicker 15 " cvr dual voice 4 ohms?
xavier t on May 18, 2016
Best Answer: Do the math.. I thibk those are 500rms a pop right? Dual 4ohm? Wire both subs down to 2ohm, then wire them together at 1ohm total load. The amp pushs well over 1200 watts at 1ohm and your subs support up to 1000watts.. It will definitely push the ever living crap out of those subs... Amps a little too powerful though so you would need to be careful with the gain setting.

is the heat syc good on this amp?
A shopper on May 25, 2016
Best Answer: I haven't actually installed and used THIS amp yet (I'm accumulating gear for a system build), however, I have installed and used 4 of the R500X1D amps on two builds and have had no issues with overheating the amps. In one installation they are mounted under the mid-row seats in a Suburban and the other has them mounted under a rear deck lid of an open top Jeep. There is not a lot of air circulating under the rear deck lid, but they have not gone into thermal protection mode. (I live in Central California and we get 100+ degrees in the summer.) I would expect similar results with the R1200-1D.

Since it has dual outputs how do I wire only one sub to the amp?
Dillpickle299 D on Oct 5, 2015
Best Answer: That gets into "bridging" connections. Depends on the ohm rate and true rms of the sub you are using. If you connect one positive and one negative (one from each output) from the amp to the sub then you will have a higher output rate than if you just used one output side. All depends on what the sub can handle. Research and wire it the right way or you will be blowing your sub in less than a year.

Best Answer: Yes it will just make sure you run them together into the amp, that's what I am using it for. 2 12" P3 and it works amazing, just make sure your power supply getting to it is sufficient.

I'm wanting to power 2 alpine swr10d4's, how well would this amp push these subs? How does it compare to the rockford fosgate prime 1200.

Alpine SWR-10D4-OB
Best Answer: depends on your electrical system. the p1000x1bd will require a very upgraded charging system but if set up correctly it will have more sound pressure than the r1200-1d. On the other hand, you can get away will very good pressure and sound with the r1200-1d with just a stock charging system and a cap. The difference in price and free bass knob is why i would choose the r1200-1d. The R1200-1d is no wimp by any means and is a great value for the price

So since the amp shows two channels for speakers how do I wire a 1ohm load to this amp? Do I wire both speakers at 4ohms n then place each sub into their own channel to make 1ohm?
Thomas F on Jul 12, 2015
Best Answer: Hello Zack,

This amplifier does NOT show two channels. It shows two outputs, yes, but no where does i suggest they are channels, they are only outputs. Intended to make wiring of multiple subwoofers easier. Assuming your subwoofer have the ability to be wired to a 1ohm load, then you would simply wire each individually to a 2ohm load , give each on its own output and the amplifier will bring the connections together, thereby showing a 1ohm final load.

Please consult the manual and/or a professional installer for further assistance.

Will this amplifier work with 4-TS-W3003D4 subwoofers?

Pioneer LS-TS-W3003D4-OBI
Best Answer: Chad,

As said before, you seek an amplifier providing ~1200 - 2400 watts RMS @ 2ohms. This amplifier says "2 ohms: 800 watts x 1 chan." , which doesn't fit within the recommended power range. Two of these for each pair would be fine, but not one. (At the moment, Nothing in the Rockford Fosgate line has the power output you seek.)

I suggest giving our sales team a call to help you find what you're looking for.

Will this be a good amplifier to power two of the Rockford Fosgate Punch P3D4-12 subwoofers, if wired in 1 Ohm configuration?

Best Answer: You will get just enough power to run them. A ported box would allow this amp to do well as the box will allow easier air movement allowing the subs more excursion with less power. For the price you will be happy

I have 2 P3D2-12 sub and not sure how to wire them for this amp. Can someone tell me how to do this?
David J on Dec 23, 2015
Best Answer: Hi David,

Before clicking on the links below, we have to stress that we are using the pictures to show you the wiring, DO NOT WORRY ABOUT THE FIGURES (numbers). Again, SIMPLY FOLLOW THE WIRING. Yes, the impedance is different, yes we understand that. Again, we are sharing these to answer your question. Also, it does not matter which of the two methods you use, they provide the EXACT same results, a 2ohm final load (Yes, one of the picture suggests different, we get that, trust us.)

http://www.sonicelectronix.com/product/img/subwoofer_wiring/2_subs_DVC_2_ohm_2ch.jpg

Again, neither is "better" than the other. It all depends on which you are able to manage.

is it brigdable?
A shopper on Dec 21, 2014
Best Answer: Hello,

The Rockford Fosgate R1200-1D is a MONOBLOCK, which means ONE Channel. Therefore, it is impossible to bridge. There needs to be at least two channels to "bridge", to have the feature. This is why the description doesn't refer to the ability to "bridge" . Do not confuse the multiple outputs as being "channels" , they are Not, they are simply outputs wired in Parallel internally.

How do I wire my dual 4ohm woofers to 4 ohms on this amp? Or this isn't possible
A shopper on Nov 7, 2014
Best Answer: Hello,

1 Dual-4ohm subwoofer CANNOT be wired to a 4ohm final load. That is, in fact, impossible (without warranty-void modifications) . Your options are 2ohm or 8ohm .
