Hi

I have a Phoenix Gold Octane R8:0.4 (4x75W RMS at 4ohm)

I am going to get a 8" Dual Voice Coil 4ohm Rockford Fosgate Punch HX2 RFD2208 which is rated at 400W RMS (200W per channel)

If I bridge 2 channels to the sub and wire it in Parallel will it run at 2ohms Ok?

I was told that I may need to get a 2ohm DVC and run it in serial to get 4ohms for the amp to run in a bridged mode. Is this true?

Thanks

 

looking at this page:

it looks like the PG R8:0.4 will peak at 400 W x 2 when bridged, and is stable only to 4 ohms when bridged.

this sub will work fine as it has a peak power handling of 800 W total and each coil is 4 ohms. you'll want to brdige your amp to 2 channels, then run each bridged pair to 1 voice coil. be sure to send a MONO signal to the amp.
