Rockford fosgate usually work best with 2 ohm speakers. Depending on the resistance of your speakers, will then give you best connection. Check the resistance for the subwoofers. If the subwoofers are two ohm then connect them directly right and left. But if they are 4 ohm connect them parrallel (positive to postive, negative to negative and bridge the amp.) Good Luck, please rate.

I need to wire up a rockford fosgate punch hx2 12" subwoofer to a 500 watt single channel amp and i need to know how to wire the dual voice coil properly ??


Wire it in a series. One wire from amp positive to one positive speaker terminal. One wire from amp negative to negative speaker terminal. This should leave one positive and one negative termianl on the sub. Use one additonal wire to connect these two, this wire should not be connected to anything else other than the two remaining terminals. This will allow you to have the music up louder with higher amp settings without having to worry about blowing the speaker as easily.

This means you have a dual voice coil sub. It is probably a dual 4 ohm voice coil. If you hook up the left channel to one input and the right to the other you can safely push the sub but the amp will be running at a lower efficency. In other words it isn't the best amp for the job because it can't push max power to a dual voice coil speaker but it will work.

Subs


Hi,

First of all you need to check if your amp can support this type of speaker setup? If you are simply going to wire 2 subs up to the amp (assuming a 2 channel amp) it's pretty simple. Just connect the + & - cables to one channel of the amp & the other ends of the cable to the sub, making sure that they are the correct polarity on both sides (ie speaker & on the amp).
If on the other hand you want to 'daisy chain' the subs onto one channel of the amp (this effectively drops the load down to half that of the speakers (usually 2 Ohm)), then you do as the name suggests. Simple connect one speaker cable to the amps channel 1 + ve output to subs_1 +ve input. Then from sub_1 -ve connector to subs_2 +ve. This leaves you with only 1 more to connect sub_2 -ve back to amp channel 1 -ve.

NOTE: make sure that your amp can support this first! If it can't then it's will auto switch off in most cases but can also damage the amp if there is no fail safe circuit built in.

Trying to wire my amp to my subs


no thats not it you are lucky you havent burned it up like that. wire each speaker to its own source positive and negative, you loose power when you bridge an amp and use two speakers, its best to hook up without bridging you will get more volume that way.
