SOURCE: Rockford Fosgate 501bd question

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.

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.

SOURCE: Rockford fosgate 800 a2 amp power?

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.

SOURCE: Will my car handle a rockford fosgat 801s power load?

Hello dreww1005,

If your alternator and battery are in good condition, you probably don't need a capacitor. At maximum output, the 801S will need to draw a little over 30 amps at 12.8V. The specifications call for 8-gauge power and ground wiring and a 40A primary fuse. The Vibe's electrical system should be able to handle it OK.

Hope this helps.

How do I hook up one sub to my rockford fosgate p3001 amp


Hey i have looked over many rockford manuals,(i own a 300.1 my buddy owns a 325.1) and for there mono(.1) amps there hooked together on the inside so channel A+ and B + are cencted on the inside the amp. So you ither hook one 2ohm sub to channel A or you can hook 1 4ohm subs to channel A and 1 4ohm sub to channel B. There 2ohm stable so any lower will eventualy burn the amp out.

Rockford Fosgate T15004 The Amp still powers up with the


Check you inputs to verify you have a signal coming in, if signal then check outputs try a speaker that you know is working and plug it in if that speaker plays then the subs/ or speaker wiring is bad, if it doens't play then you probably have a blown output transistor on the amp or possibly a terminal ground/positive has come loose on the inside..

Connect rockford fosgate amplifier & speaker together


Assuming your P3 has a single voice coil (it will have only one place to plug your wires into) you will be running this in a bridged mode. You will take the left (+) coming off the amp and plug it into the (+) on the P3. Then take the right (+) from the amp and plug it into the (-) on the P3. This will make your amp push 500 watts to your sub. Now on the amp make sure your adjustments are as follows: Signal input switch is set to unbalanced for RCA input. Left Phase switch is set to 0. Right phase switch is set to 180. your X-card should be set to low pass. And adjust the gain for both R and L equally so it has equal power from both channels.

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.

Is this ok?


yes 2ohm should be fine for that amp no problem

But dont bridge it any lower than 2 ohms.
