I want to connect my two rock ford fosgate power hx2 tens to a boss pd-4000 amp.Can someone please tell me how many watts will be going into each sub. One power hx2's rms is 1000 watts and its peak is 2000 watts, it has dual 2ohm voice coils. The amps information can be found in the link below. Please help.Help with amp wattage. - Last Post -- posted image.

Assuming you are referring to the RFR3110 Power HX2's, and the specs on the Boss site are correct, then the amp is a decent match (RMS wise anyway).
The RFR3110 subs are 1000RMS 2000Peak 2ohm DVC's, so wire Bridged at 2ohms and throw the 900RMS to each sub. You'll be slightly underpowering the subs, but you shouldn't run the risk of blowing anything. Here's how to wire two 2ohm DVC's into a 2ohm Bridged/Mono load...

You could also wire in Stereo with a 1ohm load at each channel and throw 1500RMS to each speaker, but be careful not to have the gains too high with this type of configuration as you would be running above the RMS rating of the sub. WARNING... If you wire like this, you are running a serious risk of blowing your subs, even with the gains turned down. Here's how to wire one 2ohm DVC per channel into a 1ohm load (each sub would look like this)...

You'll never get the 0.5ohm load since (according to the Boss site) you have to be in a Stereo configuration (not Bridged) to get the 2000RMSx2. But that wouldn't be a good idea anyway since your sub's Peak rating is 2000 watts!
