i am thinking of building a custom subwoofer using a mmats pro audio 12" subwoofer. It is called the procast or p3.0...

It is dual 4 ohm voice coil. I am trying to sell them but not having any luck so i was thinking of building boxes for them.

i Don't know what i should use for amplifiers... Any suggestions would be great. 500watts and up can be handled by these beasts.. here are the specs.. If i sell these i'm looking at a sunfire sub or a klipsch rw-12d

P3.0 12

Voice Coil (Ohms) 2 x 4
Fs (Hz.) 26
Vas (Liters) 84.0
Qts . .18
SPL (1W/1M) 92db
Power (Wrms) 750

See pic attached. On the bottom off the remote you can hit CH Sel button until you see subwoofer come up on the on screen display on the onkyo. The use the plus and minus to increase and decrease the level.

The better way is to go into the setup menu, then speaker set up and level calibration and adjust it from there.

This way it records it in so when you turn the receiver off and on again it doesn't change back to what you had previously which is what happens when you just select the CH Sel button on the remote.

You can use the CH Sel button just to get the levels correct.

cheers

Hey mike p. I’m wondering if you can help me design a new box design again?

been many years with the build you helped me with and I’ve purchased two more subs.

Im either building two more separate boxes and stacking them or looking to build two big boxes with two subs in each..

I still don’t have a laptop to access winisd and iPhone wont support it..

I did find our old conversation with port size so i can duplicate the box but wasn’t sure ifa new box built with two subs together and one port would be better.

thanks jon
