I have a 200a4 watt rockford ampp that I want to push 2 10 inch rockford woofers in a band pass box.

I want to bridge the amp to push the speakers. I would like to know if this is right.

pwer wire to positive on one channel and negative wire to negative on the other channel. This shold combine the 2 channels together and make it 100 watts. Is this rights?

Also should the amp be on low pass and I should adjust the gain once I have listened to subwoofer paly.

I also ran a 2 gauge wire to a distribution block and ran a ground distribution..........

this is not right my friend:

you need to figure out the ohm load of subs first, and then look at a your amp as two seperate ones. one is your A channel, and one is your B channel....you can bridge each channel down seperately, one to each sub.

hope this helps
