hooking up a dual voice coil sub?
hooking up a dual voice coil sub?
hey guys, i have a 12" memphis sub, ported box, and a 760w sony amp. the amp is 2 channel and the sub is dual voice coil. so... i was wondering... how do i hook the sub to the amp with the dual voice coil. i was thinking that you hook the two positive connections on the amp the separate positive connections on the sub.. and then you take the negative and hook it to the opposite negative on the sub. is this right? ill put a picture of what i just described... i appreciate anyones help. thanks

I'd hook up one voice coil to each amp output. That's how my current one is configured.
You have to consider impedance if you are going to hook them up in series or parallel. If the coils are 4 ohms, and you hook them up in parallel, that's a 2 ohm connection now. You would use your amp in "bridged" mode for this and does it drive 2 ohms okay?
If you hook them in series and go bridged, that's 8 ohms and you might not get the full power of the amp in that configuration.
Tell us some more about the amp model and speaker specs and then folks can tell you better.

go here and select your specs for the sub, amp, and configuaration, this will give you a diagram:http://www.rockfordfosgate.com/rftech/woofer_wizard.asp

That's good. Now if you get the voice coil ratings you can use the link that Brandyn gave you to determine what works.
The link doesn't give a minimum inpedance bridged, but it does use 4 ohms as the value they tested at. If you have a dual 8-ohm voice coil sub, then you can hook it up just like they did (parallel and resulting 4 ohms). If you have 2 ohm voice coils, you can go series.
if you have 4 ohm voice coils, you will want to use one speaker per amp and switch the amp to a mono input configuration if that's possible.
