Thought this might be helpful for the thread. This comes from the tutorials at the JLAudio site. They have the single voice coil also. There's also pics at the site.

Wiring your subs: Dual Voice Coils
With multi-driver sub systems, which often feature dual voice coils (DVC) on each driver, the level of wiring complexity can be enough to turn-off even the most adventurous of car audio do-it-yourselfers. Fear not though, for we have compiled wiring diagrams of several configurations for dual voice coil (DVC) drivers.

Please note that when wiring multiple drivers it is recommended that series connections between drivers be avoided at all costs. This does not include series connections made between voice coils on the same driver. For more information, please consult our dual voice coil tutorial.

Additionally, if you have an idea for a wiring configuration and you do not see it here, chances are you should re-think its implementation (in other words, don't do it). You will more than likely find that the results will be less than optimal.

Just so you know, if im not mistaken those jumpers can be attacked through the top of the terminals aswell

 

Give me a budget to work with for the new amp please.

 

You might be better off money wise finding an amp that runs at 0.5 ohms and then beefing up your wiring/power situation to support the increased amperage.

 

I plan to spend around 400-500 max

 

You're right, I forgot thats actually how they're supposed to be wired. Everythings back in the box.

I feel so ripped off..
The 10 inch type-r's cost around 250 each, and 12 inch type-x's are 239 online. Same thing with the amp. The 2000w version of my amp costs the same price online at sonicelectronix.com

The plan is to sell most of the components and buy new online. If I have to add a couple hundred, so be it. Any suggestions on whether or not running the door speakers off the Head-Unit would be a good idea?

 

Your amp is over heating due to the fact that you have it wired down to 0.5ohm
Wire each sub up to 4ohm.
Leave the rest of the wiring as you have it.

 

I would get the wiring issue sorted out before you decide you have been ripped and go out and spend more money. Once the subs are running properly then work on the rest of it.

Your comps will sound like poo running off the deck compared to the amp. If you are planning on adding more bass at some point you might as well leave the amp in there unless your goal for the system is a bass machine only......2kw of bass and it's going to take some sturdy mids and highs to keep up.......
