All Night Long

Sorry, I don't have the 12's yet I am waiting for them to get back from being reconed into 12's from 10's that score of 141.4 is from the two level 4 10's.

I agree that 1500 is pretty good for that sub. I have 2 level 4 12's with the level 5 coils and I run them with a Crunch Groundpounder Pro 3000D and they slam. For two 10's in a trunk car they do 141.4 on the dash.

I don't think that it would work out that well anyway. I never use two different ports for a single sub. It is best to keep the airflow going into one port for maximum spl.

I agree that Crunch is more of an entry level Hifonics except for the GP Pro 3000D. That amp has the same quality components and same quality board as the Hifonics XXV line. There is a thread on Termpro that discusses the power of the groundpounder amps is anyone is interested I'll look it up.

2500 watts may be possible with a 16 volt system and this amp, but I'm only getting 2800 out of my Crunch GP Pro 3000D at 1ohm. The impedence rise is from 1 ohm to 2 when played and is seeing a constant 14.8 volts. The 3000D is capable of 4000-5000 watts on a 16 volt system and a low reactive load.
