Can I run 2 12 inch 2ohm fosgate and a 4 ohm 12 on a rockford fosgate 401s 1200 watt amp

In series, yes

Rockford Fosgate 401s 400 watts RMS x 1 bridged

Dynamic Power Rating (measured at 14.4V):

• Bridged Into A 4-Ohm Load: 450 watts x 1
• Per Channel Into A 2-Ohm Load: 225 watts x 2
• Per Channel Into A 4-Ohm Load: 115 watts x 2

yea you could run a single fifteen it would be a good combination

rockford fosgate doesnt have watts its considered monoblock it gives off watever the speakers want....it gives them the power they need

Hello ronnieyannon,
A single 4 ohm speaker wired to each channel, like you have them wired, presents a 4 ohm load. And it appears that you have them connected properly. The 401s is only stable to 4 ohms when bridged, so if you were to parallel the 2 4 ohm subs in bridged mode, the load would be 2 ohms and the amp would most likely overheat and go into protection.

I'd wire them the way you have them wired.

Each channel of the amp outputs only 100 watts into 4 ohms. That is adequate for regular full-range speakers, component speakers, mid-range drivers, and even some small subs. But it is a little low on power for most subwoofer applications.

Hope this helps.

Power caps store power from the battery and they feed constant power to the amp so you dont get no drainage! this could be one reason..

have you bridged both subs and wat gauge wire are you using.

these amps can only handle one bridged sub at 4ohms and this amp is recommended that u use 8gauge or higher. if your running to subs i normally reccomend using 4 gauge power wire as you get more rms power feed to the amp

you can get a power cap or anyother accersory cheap online at my suppliers.. caraudiosecurity << click to enter >> hope this helps and please rate me :)

if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

Can somebody email me the schematic for the Rockford Fosgate 401S?

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.
