You cannot parallel two subs AND run them on the Bridge. You must have at LEAST a 4 ohm load on the bridge, and 2 4 ohm subs in parallel equals TWO OHMS. BAD!!! Move each sub to it's own channel or your amp will soon fry.

I have to hook up 4 amps in my car. 4 channel 700 watt ken wood, 2 channel 800 watt Sony, 4 channel 740 watt Jensen ,and a 2 channel Rockford fosgate. Which is best way to hook them up so I'm not ki

Pace posted on Saturday, March 05, 2005 - 01:08 GMT Your subs are dual 4 ohm voice coils so if you want to bridge your 2 channel amplifier to your two subs then wire them parallel, meaning the + to + and - to - ( Do this to both subwoofers), Then run a wire from one positive and one negative on each sub and bring the two positives together and the two negatives together and hook both positives to the far positive connection on your amp and connect both negatives to the other negative on your amp,

This will create a 4 ohm load on your amp.

Although if it's a two channel and you have two subs it's usually pointless to bridge them because if you use one channel per subwoofer its going to be the same as if both subs were bridged. example) 800 watts x 1 bridged power of your amplifie (4 ohms) is the same power as 400 watts x 2 at 2 ohms.

Xm-2002gtr amp keeps kicking protect light on

check your amp and speakers and make sure their both hooked up 4 ohm instead of 2 ohm because if you have 1 set of voice coils on your speakers they can only be hooked up four ohm and not bridged to your amp because if you keep trying this you will lock up your speakers if the speakers are only 4 ohm than just hook them up regular to each channel on your amp if your trying to brigde four ohm speakers to your amp it will keep going into protect or worst case scenario you will fry your speakers and you can check your ohm with a ohmmeter trust me my brother owns a stereo shop

I have 2 1100watt sony xplods will they run off a 1000 watt amp

yes it will work, but it will only put out the power to the sub that the amp allows, ie : 100 watt amp puts out 100 wats.
you can also try reconfigering your wire to your subs, if your amp is 1ohm stable and your subs you can come off the amp with a bridge and run subs in series or parralell, this will dramaticly improve the bass

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
                Two
            -          +  
            |           |
amp (L) - + (R)- +


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

Protection mode override

If you have your subs wired to the amp in a bridged configuration, try wiring one to each stereo channel instead. Also, make sure your ground wire is secure and connected to a clean, solid metal part of the vehicle body with the paint scraped off. If this doesn't work, disconnect both subs and try connecting only one at a time; one of the subs may have a problem that is shutting down the amplifier.
