How do u bridge a 2 chanel amp and two subs?

Question

i need a wire diagram and also i heard that you subs need to be dual voice coil in order ti bredge them is that true

Answer 1

your subs do not have to be dual voice coil to bridge them to an amp

hope this comes out right:

wire = -------------   (ignore the periods i used that to space the wires apart)  Note: it's not spacing it out as i'd like it to be.

basically your going to take the positive lead from the first speaker and put it into the pos. input of the amp. then your going to take the neg. lead from that same speaker and connect it to the pos lead of the second speaker, then take the neg lead of the second speaker and connect it to the neg input of the amp.

(+)  speaker 1  ( - )    ----------------------  (+)  speaker 2 (-)

+ amp input...................................... amp input

this is called a series wiring between two 4 ohm speakers to connect to your amp if it's mono capability is a 4 ohm load.

if your amplifier is capable of handling a 2 ohm load then just connect the positives leads of both speakers to the pos. input of the amp and both neg. leads to the neg. input of the amp.

Answer 2

It depend on your sub and amp spec.  If your sub is svc 4 ohm, you can wire each sub straight to each channel of your amp and get 4 ohm load.  If you wire 2 sub together in parallel (+ to + and - to -) then to your amp, you'll get a 2 ohm load.  If in series (amp - to - 1st sub, + 1st sub to - 2nd sub, + 2nd sub to + amp), you get 8 ohm load.  

For DVC sub, the wiring is basicly like 2 svc sub for each driver/speaker.

Normally, your 2 channel is running at 4 ohm for each channel. If it's bridgeable, then it can either run 2 ohm load (double power) for each channel (non-bridge) or briged into one channel at 4 ohm load.
