2/4 Ohm Question

New guy, first post, but a silent reader for awhile now.
OK, I'm sure a simple answer to the majority of you, but confusing jargon to me. I'm running a MTX TC510 (4 ohm 300 watt) combined with an MTX TC4001

http://www.mtx.com/caraudio/products/amplifiers/TC4001.cfm

Now what I'm wondering is, to run the amp and sub together at 2 ohms, do I bridge the 4 terminals on the sub as pictured?
Thanks in advance!

Yes, you do.
Can you verify that your sub is a 4 ohm dual voice coil configuration? I'm trying to find out myself, but can't. Even MTX's site doesn't have that model listed in their product archives.

Thanks Tragic, that is/was exactly what I've been trying to figure out as well. The speaker doesn't say whether it's a DVC or not. But it does have 4 terminals. So I am assuming it is a dual?

OK...I'm at a loss...I started to rewire the sub this morning and after studying the terminals, I think this sub is a SVC as although there are 4 terminals, the pos and neg are really both connected to each other as it is. I hope the pic better explains what I mean, (please excuse the blurriness). My assumption is the speaker is like this to be able to wire multiple speakers together in series or parallell?
So does this mean I can't run and get the most out of my amp wiring it as a 2 ohm sub?

That is correct. You either need another of the same subs or change to a entirely new sub if you only want to run one sub.

It's only a single voice coil. You can only wire it as such. One pos & one neg. The others are to allow you to wire more than one sub together. Remove the extra wires.

OK, great. Thank you both for confirming my thoughts.
Out of curiousity, if I did run the amp wires to the sub as a 2 ohm (the amp is capable of doing 2 or 4 ohm)...Will it blow the amp? Blow the speaker? I'm just curious what (if any?) problems would arise.

Assuming your sub is 4ohms... Your amp will only see 4ohms if thats all your sub is. You need a second identical sub to get a 2ohm load to your amp.

If you put the extra wires on the sub and cross them you could blow your amp or sub. Just wire it like normal. Pos on amp to Pos on sub, neg on amp to neg on sub and forget about the other 2 until you buy another sub.

Thanks again. No, I have the wires off with no intention of trying that.
