Rockford Fosgate 501bd question

Would my Rockford Fosgate 501bd amp (300 x 1 @ 4 ohm, 500-600 x 1 @ 2 ohm) push two 10" Kicker CVR subwoofers? They handle 50-300 watts RMS at 2 ohm.

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

Can i use a 300 watt amp for 2, 800 watt woofers

yes, but you would not get the same performance as you would if you gave them the suggested power. I have found that it is always better to use a more powerful amp than your subs are rated for (as long as it is clean, high quality, low distortion power). I have had the best luck with name brand amps (kicker,rockford fosgate,phoenix gold,etc...). I hope this will be helpful to you.

I had Rockford Fosgate P300-1 Amplifier installed professionally with a Kicker CVR10 10 in Subwoofer in 2010 Comaro. My problem is that it causes an odor in my car. I took it back to Mothers window tint...

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.

How do i wire a kicker cvr if it has two reds and blacks

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, click support, then click woofer wiring wizard, this will answer all your questions about dvc subs.

Overheating amp problem...easially fixed, i think....

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

look it up google for diagram if you need one.

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.

Sub Wiring

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".

Rockford Fosgate 800a2 To 2 SVC 2ohm subs

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

So. this how it goes.

sub1 + -
to      | |
sub2 - +
=      4ohm

           From Sub
            -          +  
            |           |
amp (L) - + (R)- +

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