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.

Well you really can't run both speakers on one term. because you will over heat the amp , unless your amp is rated at twice the capability of your subs , Then if so , Try positive to one sub , then neg. to the other sub , then bridge the remaining positive to the remaining negative terminal , But it is really best to get a two channel amp for your subs !!!

I would bridge down to to 2 ohm mono.

the sub is a dual voice coil, and depending on how you wire them, gives you different bass response as it drops the ohms in your amp. it can be wired for 2 ohms one way 4 ohms another way or 1 ohm depending on what ohm the coils are. to learn more about this got to rockford fosgate.com, click support, then click woofer wiring wizard, this will answer all your questions about dvc subs.

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".

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:
