Question about Car Audio & Video
Without looking up the individual specs of your speaker and amp, I'll offer a few basics when it comes to bridging an amp.
Most important...find out what impedance (ohm) that your amp can handle bridged!! If you go below this rating, you will run the risk and most likely eventually overheat and short circuit the amp. You must also know the impedance of your sub (which can come in a variety) to be able to match them. Depending on this impedance match-up, it may be less beneficial to bridge the speaker to this amp. For example if there is an impedance mismatch you'll either get less power from the amp or short circuit the amp. If you know these I can help you come up with the best solution.
If you know bridging is the best option, then you'll have to know which terminals on the amp to use in order to bridge. This is how it normally works. On a 2 channel amp...you would normally take the positive from one channel to the positive on the speaker, and the negative from the OTHER channel to the negative on the speaker...and this is how you bridge the amp. The other two channels would remain UNCONNECTED. BUT!!! you have to make sure you use the correct 2 channels...it varies from manufacturer. But take heed not overload the amp...and not to overpower the sub. There are a few different ways that you can configure the subs if you find it beneficial to bridge your amp, these would take long to explain and would depend on the impedance of your subs and specs of your amp...these wiring configurations is how you match the impedance of the speakers input to the amps output (and is very important to do correctly) Look up "parallel and series" wiring configurations. Let me know if this helps, or if you need further help. Find out the impedance of your subs and the specs of your amp and i'll be able to assist you more. Hope this helps.

This will allow 2 channels to run 100 watts each @ 4ohms with an additional single channel with 250 watts @ 4 ohms.
The single sub channel is created by bridging channels 3 & 4
