Question about Rockford Fosgate Power 1050S Car Audio Amplifier

I need help real bad!! what would be the best way to wire this subs to the amp? because i dont want to burn the amp or the subs because of my negligence

Sorry:

Sensitivity: 87.6 Db

RMS Power range: 400 Watts

Peak Power handling: 800 Watts

Impedance: Dual 2 ohms

Low frecuency responce: 25 Hz

High frecuncy responce: 500 Hz

I'm not sure what you mean... there's generally only one way to wire a sub to an amp.. unless you mean wether to bridge the connection or if you have multiple subs and want to know wether wire in series or parallel. Please explain your situation.

Send me your email account and i will draw you a diagram and send it to you there. I will need to know if the ohms of each sub as well as the amp. I'll also need to know if the subs come with one or two voice coils.

It has two speaker terminals which allows you to wire muliple subs to the amp easier than trying to cram the wires all into one set of terminals. The two sets of terminals are wire in parallel internally on the amp, so it matters no which + or - you use on it. However, you need to remember they are already wired in parallel internally, so if you were to wire up two 2 ohm subs, the amp would see a 1 ohm load (which it's not stable at), not a 2 ohm.

your kicker cvr subwoofer should have a max power of 1600 watts therefore your amp is not too much for the sub because the p300-1 amplifier has a max output of 900 watts. if anything your amp would not be enough to produce max power out of your subwoofer. your sub should not produce an odor unless you have your amplifier bridged which doubles the watts pushed to your subwoofer and if that is the case your amp is pushing 1800 watts to a 1600 watt sub which could be causing it to fry or possibly blow soon. other than that if thats not the case there shouldnt be a problem.

Hello a_brake11,

The P325.1 is relatively small to power a pair of P3's. You'll only get 325 watts RMS at 2 ohms (162.5 watts per sub). The P3's power range is from 100-500 watts, so they will work, but don't expect them to be really loud.

For best power, your subs should be wired with the voice coils in series and then the 2 subs paralleled to the amp resulting in a 2 ohm load.

Hope this helps.

depends on the sub rating.

if subs are 2 ohm rated you can ONLY get 1 or 4 ohms..

2x2=4ohm series

2/2=1ohm parallel

if subs are 4 ohm rated wire in parallel

4/2=2ohm

look it up google for diagram if you need one.

Hello desperate2le,

Watts delivered is a function of the voltage times the current. If the amp was 100 percent efficient, it would need 33 amps at 12V for 400 watts. At 14.4V, it would only need 28 amps. Of course, amplifiers are NOT 100 percent efficient, only about 50-60 percent in many cases, but somewhat higher for monoblocks, maybe 80-90 percent. So you're looking at a fuse in the 60-80A range. In the absense of a specific fuse size from the manufacturer, I'd start the primary fuse at a 60A and if the amp blows it on power up/immediately/frequently, move up to an 80A.

All of the Rockford-Fosgate 2-channel bridgeables I've ever seen show using the left positive (+) and the right negative (-) for bridging. But if it's not shown right on the amp, I'd call or email RF for the correct connection. The new amps do show it.

Hope this helps.

Hello jtkpay,

Rockford-Fosgate claims their latest V-power 1500bd is stable to 1 ohm, and I would think that your Oldschool would also be. The 2 wiring options for 3 subs with 2 ohm dvc would give you a 1.34 ohm load and a 3 ohm load. The 1.34 ohm option would mean more watts to the subs, but the amp will run hotter. The diagrams look like this:

Using just 2 of the Kickers, you can wire 3 different ways, with final impedances of 0.5 ohms, 2 ohms, or 8 ohms. You do not want the 0.5 ohm load. It's bad for the amp. You don't want the 8 ohm load. It doesn't allow the amp to produce as much power. So that leaves only the 2 ohm, with coils in series and subs in parallel. It looks like this:

Hope this helps. If it does, please rate as "FixYa".

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up without the thermal LED being lit, the wiring needs to be checked. If it still indicates that it's in thermal protection, it needs to be serviced. A local repair shop will be the quickest. Rockford will email you the schematics.

Ok.. Bridge the two sub into 4ohm than bridge to amp.

So. this how it goes.

sub1 + -

to | |

sub2 - +

= 4ohm

From Sub

Two

- +

| |

amp (L) - + (R)- +

This will use the full potiental of RF 800a2 amp. I believe it like 1153 watts max out.

that amp should work fine with those speakers,just make sure that they(speakers)are wired for 2 ohms.at 500-600watts coming from amp, you should be getting 250-300 watts per speaker,just dont crank your gain too high on the amp.

First of all thanks 4 answear , sorry bout my english it might b kinda rough..

Well i dont know how to wire the subs as in parallel or serial or how because i think the amp pushes 1050 watts on bridge but the subs each one pushes 800 watts and i got 2 the problem is how to conect or wire the subs in a safe way, meaning not to burn the subs or the amp if you can show me some kind of diagram would be perfect if is not to much to ask

This are the details on the amp:
