Help connecting external subwoofer - Page 2

post #11 of 26
you really DONT have to bridge them if you dont want to.

A dual voice coil speaker is just a speaker with two voice coils, it is in effect two speakers in one

But, you can use just one voice coil if you want...just make sure whatever you do the impedance is correct.

Ok, how do I check impedance

I have no idea what that amp could possibly be putting out, and I have no idea what the subwoofer is expecting in, but I could check that. Lets see if I can find that manual...

As far as i know..it is ok to bridge them...but first try from just one of the connectors..if it works fine..then just leave it..no need to bridge.

Ok, here is my external subwoffer manual. It says nothing about impedance. So I assume it's not importiant?

Anyone else notice that he has a CNT output on the speakers? Just use that. Plug an RCA cable from your speakers CNT out, into the RCA in on your extra sub. That'll work just fine. CNT=Center, which is the EXACT same as a subwoofer....just a mono channel.

Instead of splicing wires and ****, do that. And NO it is not okay to just run one coil. It can be done...yes, however its bad on the speaker. It'd be like running your car with two flat tires....it can be done, but its not good on it.

Good idea, that would work with music, but it doesn't work in games or surround movies. If I did that then I would only get bass for things that happened exactly in front of me

Alright, well go down to a local RadioCrack and get a RCA Y splitter. Double female to single male. Then connect your FL and FR (front left/right) outputs from the speakers to your in on the sub....again making it mono. However I think the CNT out would be the best. My sound card uses one headphone out for CNT and Sub..and both sides sound EXACTLY the same to me. I don't think it would matter...but if you felt better about it, just use your FL and FR through the y splitter. That'll work just the same. And yeah, I've jimmy rigged quite a few extra subs and what not to my computers....usually you can do it with a simple RCA cable or Y splitter....

Oh and if you have one (or a few like we do)...check the dollar store. 2 out of 3 of our local dollar stores carry simple RCA Y splitters and extensions, and other various audio cables. If not...there's always Wal-Mart..I know they have them.

Same problem. I already tried this but then you only get bass when things are to the left and right of you. If there is an explosion in front or behind you then there's absolutely no bass unless you turn so it's to your side.

Then just use the front left and right. That's all that is used in 5.1 anyway. Because its still 5.1 without a subwoofer (technically not...but still)....and big 10-12" speakers.

And when you're using only one coil, the other coil is still getting power, which is bad. You're only heating up half the wire...and both coils are wrapped together. I can't really think of how to explain it....but its pretty much the same as driving your car with 2 tires on one side flat. That's the best I can think of ATM for describing it. ALOT of stereo shops say its okay to run just one coil....but if you check the manufacturer's they list a dual 4ohm coil as either 2 or 8ohms....not 4. If you need the load the the single coil is, either get a single coil, or another identical dual voice coil.

I could go into WAY more detail.....but its difficult for me to find the words right now.
