yall are crazy... using one VC is fine

with that being said... do not put the combined RMS of both coils on one.

a lot of people use one voice coil and then do various other things to the second (leave it open, short it) to change the QTS of the sub. This was the idea behind the AA sub (the model slips my mind)... it was nothing new, just a little different spin on the idea

The above poster actually gave some insight as to why it should not be done.

It changes the parameters of the enclosure you need to put it in, a.k.a. you probably will ruin it because the box has an extremely high chance of being too big or too small.

A common misconception with regard to dual voice coil speakers is the assumption that nothing changes if you power only one of the voice coils. With only one coil hooked up, a dual voice coil speaker will suffer a loss in reference efficiency of about 3dB (only half the coil windings are being energized) as well as a significant shift in its Thiele/Small parameters. This renders any enclosure calculations inaccurate unless you remeasure the speakers parameters with only one coil hooked up. Failure to account for the different parameters of a dual voice coil speaker with only one coil powered can result in very poor performance.

i believe you could do something to the effect of changing the ohms on a Ava from 2 to 4 and it raised the efficieny of the driver....i dunno WTF i am trying to say....

on the atlas you could change the qts ofthe sub, but the second VC used was not te same as the first. Thats what make teh Atlas different then a normal dual VC sub

hmm this thread made me wonder if i wired my arsenal wrong. i have the speaker wire hooked up to the right terminal and nothing hooked up to the left one. the sub is 2 ohms and the amp is putting out 750w at 2 ohms. is my sub hooked up right?

im thinking should i have it hooked up like the top right sub http://mobile.jlaudio.com/support_pages.php?page_id=161

because right now i only have wire going to one of the terminals and nothing to the other. would it be best for me to hook it up + to + and - to- like the diagram. thanks all for the help

correct, you should wire it like in the top right picture. then you would have the vc's in parallel and give you a single 2 ohm load for that amp. you should be pleased with the results when done, if you havent already messed up the driver from only having one voice coil hooked up.

IMPORTANT NOTE! EVERYONE, QUIT WINGING IT WHEN HOOKING UP SUBS. IF YOU DONT KNOW EXACTLY WHAT YOU'RE DOING, GET HELP. QUIT ATTACHING SOME WIRES TO SOME TERMINALS AND HOPING FOR THE BEST! GOD!
