hey guys just got a new sub yesterday and am looking to wire it up myself this afternooon...it has 4 terminals, 2 + 2 neg, with these jumpers connecting them...any idea what I should do with wiring them up?

Well, is it a dual 4, 2, or 8 ohm sub? That's kind of important....as well as the amp you will be using.

12<b>4</b>2 denotes 4 ohm.....its the mrd m605 v12 600 watt amp.

so you are saying it's dual 4 ohm?

ok, what are the specs on the amp?

you could wire each voicecoil to a channel on th amp, you could bridge the amp and run the sub in series for a total load of 8 ohms, or parallel for 2 ohms if the amp can handle it bridged.....

its a mono amp and i have 2 of these subs now....

Still not exactly full of information. I'm done trying to draw it out. I suggest you post all information on drivers, amp, power system, signal feed...etc before asking for help.

The MRD-605 is 600X1 @ 2 ohms.

You have two dual 4-ohm subwoofers and you are trying to connect them to a 2-ohm stable amp. Unfortunately, this is not going to work very well. You can hook the subs up in one of two ways; first is to wire the subs' VCs in series and wire the subs in parallel to the amp. You would do this by connecting the + terminal of one of each woofer's VCs to the + output of the amp, connecting the - terminal of each of the woofer's other VCs to the - output of the amp, and then wire the remaining terminals on each woofer togther. This gives you a 4-ohm load at the amp, which is going to give you only 400W between both woofers.

Or, you wire everything in parallel by connecting all of the woofers' + terminals to the + terminal on the amp and all of the woofers' - terminals to the - terminal on the amp. This gives you a 1-ohm load at the amp, which will ensure that the amplifier has a short and miserable life.

What you need are two dual 2-ohm woofers which, when wired up as in the first example, will give you a 2-ohm load at the amp. So, return those sonofabitches and get the dual 2-ohm version.

---------------EDIT---------------

You may be okay with only 400W to split between the two woofers. However, they are rated @ 300W RMS and they have a relatively low 87db/W sensitivity, so you would be better off giving them the whole 300W, I think.

You can hook them up but youre only gonna get ~300watts total from the amp. Maybe even less if thats rated at 14.4V

The amp is rated 400X1 @ 4-ohms (@ 14.4V.)
