I have 2 4 ohm dual voice coil Legacy's. I can't show a pic or anything , but would this sound right? I have the + wire hooked up to the positive on the farthest left side ( as you're looking at it), and I have the - wire hoooked up to the farthest right side. Same goes for the other sub. There is one positive and one negative on each sub that has NO wire connected to it. I get bass, but it just doesn't seem right not having wires hooked up to the open terminals. The woofer wiring diagrams just screw me up more. Could someone please tell me if I have them hooked up right?

what resistance are you looking to end up with at the amp?

you should use all 4 terminals to get a 2 ohm load connect the [sub] + to + and - to -, then connect the corrisponding amp wires to either terminal to get a 8 ohm load connect the + of coil 1 to the + on the amp, then connect the - on coil 2 to the - on the amp then you have to jump the - on coil 1 to the + on coil 2, this makes the power go from one coil to another before leaving the sub I hope that helps, sorry for spelling it is early here.

Depending on the load stability of your amp, there are many options for wiring those woofers.
Post the amp models as well, so we can look at your setup as an overall, and we can give better information to you.
Lastly, NO, YOU DO NOT have to use all four terminals. You do not have the same power handling without using all four (it is reduced to slightly more than half), but using all four is not a mandatory thing!

yea, it is just more efficent if you use all of them, but you dont have to. just like it is more effectient to run it at 2 ohms if your amp can handle it

if amp is 4 ohms stable... and subs are dual 4's...then. sub one - (+) of vc 1 to(-) of other vc creates 8 ohms same on other sub run (+) of both to (+) amp, then (-)'s to amp .......ta-da, 4 ohms ------------- Uncle Gumby

LWF12X - Legacy "L" Series - 12" 500 Watt 4 Ohm Car Audio Subwoofer https://images.amazon.com/images/P/B00005Y6OS.01.LZZZZZZZ.jpg Here is a perfect picture showing the terminals. It's 500 watt by the way, not 300.

Ok, that tells me what kind of woofer you have, but I asked for the amp... I already knew the woofers were dual 4 ohm, you said that in your opening post.

ummmm, hold on there turbo... No, it is NOT more efficient to run at two ohms "if your amp can handle it". Whether your amp can handle it or not, it is NEVER more efficient to load an amplifier all the way to its maximum safe load. Ever wonder why an amplifier gets hotter when loaded with a lower impedance? That's inefficiency at work. ------------- It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Sorry, it's a Boss C-450 (300 watt x 2)

Here's the diagram... Use the bottom one, and bridge the amp - your instruction manual will describe that process. You will have a load of 2 ohms (per channel - it's maximum safe load), which will give you maximum power capabilities. I wouldn't worry too much about sound quality - that amp has none. I would also not even come CLOSE to believing that amp makes anywhere NEAR it's advertised power - probably more like 200 watts... Total... You might be able to push it to 300 watts bridged into 4 ohms. ------------- It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice.

I ditched the 2 Legacy's and bought one: Kicker CompVR 05CVR122 12" subwoofer with dual 2-ohm voice coils So, I'll work with that. Maybe get a better amp too.
