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. ------------- Support the12volt.com

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?

Oops, you're right. Good catch. Can you hear me smacking my head?  Still, I say upgrade everything. Throw that POS MA amp in the trash (i.e. sell it on eBay.) ------------- Support the12volt.com

So what's so bad about the MA?

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.

MA Audio is a low-end product with unreliable ratings and short life expectancy. For what it costs or maybe a bit more you can purchase much better equipment. I do not think MA Audio stereo amps are designed to be bridged into a 2-ohm load, but I could be wrong as I've not looked at them for a while. What is the model number of your amp? ------------- Support the12volt.com

the subs are 300w rms and thats what you are feeding them? I guess I dont understand. Get new subs with more power or port a box.
I would get duel 4ohm subs and wire @ 2 ohms

The products I went with are to conserve space I have the shallow mount subs in a box that is 11 1/2 x 10 x 32 and the MA audio amp is the HK-898 because of its size it fits behind the front seat of my corvette. Does anyone know of a better product that would fit in the space behind my seat and a box that has 1.5 cu ft. I would appreciate it
