I have 2 10" Fosgate power DVC's and a punch 250a2 amp. I have the amp bridged, one wire to the L- and one to the R+ then a "jumper" from the side the amp is hooked to going to the other sub. My problem is that when I turn up the volume, the subs kind of pop when they hit, but they don't sound distorted. The Punch 250a2 is a small amp for the subs, they can handle 800 watts RMS each. What is the deal? Should I have another set of wires jumping to the other terminals on the speaker itself, since there are two sets on a DVC? What would that do anyway? please help!

Sounds as if you've only got one set of terminals hooked up on each sub. Both of them have to be hooked up for it to sound right.

Assuming you have the subs that have 4 ohm voice coils, you're gonna want to hook them up like this: http://www.rockfordfosgate.com/rftech/wiringwizard/index.asp?WoofQty=2+woofers&WoofImp=Dual+Voice+Coil+-+4+ohms+x+2&image.x=17&image.y=7.

(bottom diagram).

You'll need to use the positive terminal for the left channel and the negative terminal for the right channel to send to the single bridged output as shown in the diagram.

If you do all this correctly and it still does that wierd popping stuff then you might have something wrong with the amp or with the subs.
