Ok guys! Well I got 2 12" FUsion Powerplatns wired up in 4ohm mono powered by a Audiobahn A8002V amp in a ported to 37hz box. What if i bought another fusion powerplant 12" and put all 3 in a sealed box and used the same amp but still at 4ohm mono! Would it be any louder? Which set up would hit harder and be the loudest? It is in Ext. cab sonoma! thanks everyone ------------- 1 15" Memphis Mojo,

You are not going to be able to get 4 ohm mono with 3 subs, back to the drawing board you go.

That amp is 2 ohm stable on EACH channel, not when bridged like you have it.

EWW. so is there any other way i could wire this? 3 subs DVC 4ohm and keep it above 2ohm or higher. But which setup do you guys think would hit harder? ------------- 1 15" Memphis Mojo,

Well, first off, going from vented to sealed, you'll lose around 3dB, add 1.5dB back in for the third woofer, and you are still at a 1.5dB defecit. Do the math... you would need a fourth sealed woofer, just to be equal to the 2 woofers in vented enclosures... Sealed woofers SHOULD go deeper in response, but are not generally as loud.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
