I currently have 2 pioneer 12" Dual 4ohm voice coil subs(they only come in 4), and a 2 channel MA Audio amplifier, right now the subs are wired just one sub to each channel at 4 ohms where I'm getting 300w rms per channel, and I want more power, the amp is stable at 2ohms x 2 @400w rms, or 1ohm x1 @ 1200w rms, and the subs are 300w rms and 1200w max. What would be the best way to wire things up to get more. Your help is appreciated. Brandon

You have them wired the best way to get the max out of your equipment. If you want more, you will either have to have a custom ported enclosure made for the speakers, or upgrade everything.

How are you getting a 4 ohm load on each channel with dual 4 ohm voice coil subs? It should either be 2 ohms or 8 ohms. Parrallel all the coils together and see 1 ohm, 1200W RMS? Dyohn have you had your coffee yet?

There is no such thing as free installation!

Oops, you're right. Good catch. Can you hear me smacking my head? 2 subs 2 channel amp -- posted image.

Still, I say upgrade everything. Throw that POS MA amp in the trash (i.e. sell it on eBay.)

Ok if I look at your site and the wiring diagrahm says I can wire them in parallel and the amp would see 2 ohm mono. And I wire the amp to bridge the two channels or would you not recommend that.

Yes bridge into mono and parallel the voice coils.
