has anyone here had experiance with the pioneer w3001 d4 subs, I got a buddy wanting to use 4 in a ported box and I am wondering if he should be looking at something else. He'll be using 1 powerbass 3000d amp on each pair. any thoughts?

I have one in a slot ported box with about 1200 watts going to it. Its fuckin loud and still pretty accurate for a ported sub. You are going to need a HUGE box if he wants to do four of them though. Hope its an SUV or wagon or it ain't gonna fit

it's a 94 fullsize bronco, I fiqure about 3.6 cf per pair, sound about right ? want to tune @ 40 hz with a sub sonic filter around 25 hz.

Sounds right. I think I did 1.75 cu. ft. @ 38 hz, but its been a while since I built that enclosure because I had a different woofer in it before
