1-12 running both voice coils, or 2-12 running one voice coil??

[ajax012400]

I've 2 MB Quart RWE 304s that will be powered by an Infinity 611a. My question is about the SQ and SPL of running both coils on one or one coil on both, eventually I'd like to get another 611a and run both coils on both speakers.

need more info... are you talking about only using one coil on each sub?

 

[ajax012400]

Yes, trying to keep a 2-ohm load..

runing the amp at 4 ohms and using all the coils would most likly be louder and sound "better"

Um... dont run just one coil on each sub it its ment for 2...

I've an ohm meter and wire.....need guidance on achieving 8 ohms per sub properly.

You can run only one coil...you have to cut the RMS in half though. I dont recomend doing that unless you really know what your doing.

no, dont run one coil if its a dual vc, period. EVER. PERIOD

Yeah running 1 coil changes the parameters of the sub. Actually i ran my apxx off one coil for awhile because i thought the other was fried...when it wasnt.

And the logic behind this is...?

Its possible, and you can do it without hurting the sub, but you have to know what your doing. As Mikey said it completly changes all of the t/s parameters of the sub.

Thanx for the input and the Fosgate link.... After I build a box for the Quarts I'll be constructing one for a couple of Fosgate Punch DVCs (old school) that have been collecting dust in my closet.... Thanx again...
