i have a 600watt subwoofer with 2 -'s&2 +'s on each side i guess its a 4channel,howdo i bridge it 2channel amp

Question

my subwoofer is a 600watt planet audio (model vxp108) it has two negatives and two positives on each side so i dont know if its a 2 channel or 4 channel you tell me, and my amplifier is a 760watt pioneer(modelGM-5200T) 2 channel. I have bridged before and i know im suppose to connect 1 negative and one positive frome each channel but im confused with this sub i dont know how too wire the speaker ... and will it sound ok,is this sub good for this amp,or the other way around...help

Answer 1

what you have is a dual voice coil sub, run a wire form one positive to one negative on the sub. this will wire it in series, then look on the amp, it should be marked as to what connects go bridged, but if it does not, just use the pos and neg on the out sides of the connection panel ({+} - + {-}) { } represents the ones to connect to. just make sure it;s a positive and negative and they are from different channels

another option is to just wire it as if you had two subs, but this can cause distortion

Answer 2

Unfortunately your subwoofer isn't a great match for the amplifier. Your sub type is called a dual voice coil, and each voice coil is 4 ohms. You can wire the sub to be a total 2 ohm load or an 8 ohm load. If you bridge the amp, it can't be connected to a 2-ohm load, so you'll have to wire it for 8 ohms. This actually won't be too bad; the amplifier will probably put out about 200 watts RMS bridged to 8 ohms.

If you were looking for a better amp to run one of these woofers, you'd want a mono amp rated for around 300 watts RMS into 2 ohms.

To wire in this way, you'd connect a wire from the negative terminal on one side of the subwoofer to a positive terminal on the other side. This should leave you with two unused terminals, which you'll connect to the positive and negative outputs on the amplifier. This is called series wiring.

If there are actually two positive and two negative connections on each side of the sub (for a total of eight connection points) then it's probably just for wiring convenience. There's a single positive and single negative terminal on each voice coil, but the terminals may each have two connectors for wiring.
