I'm buying two of those 10 inch steathbox's from subthump. I want to get these one audiobahn subs because I've heard them before and liked the quality, also because they are relatively cheap. The problem is they are 4ohm dual voice coil and I'm not sure how to wire them up together. If I were getting one sub it wouldn't be a problem, but I'm not sure on two. Do I wire them together +/+ and -/- for each coil and run that single wire to the pos and neg of each channel of the amp or is there some other way to go about it? I had a single dual voice coil sub running bridged off my amp in a steathbox and it sounded awesome, would I be better off doing that again, getting two single voice coil subs, or going with the two dual voice coil subs I'm considering. Amp is an MTX 2160. Rated at 80w rms per channel and 320w rms bridged. I bought it new though and it came with a birth certificate and was actually rated at 121x2 and 484x1. The subs are the AB AWC10T subs rated at 50-400rpms(200 for each coil) with a sealed box volume recommendation of .58-1.16. The steathboxes are supposed to have a cf of around .5-.7. So these subs should be about perfect for the boxes. Thanks for any help.

 

Thats good that they are dual 4 ohm subs, that way you can run the individual subs voice coils in series, and connect the subs to run them in parallel. This will still be able to run the amp at 4 ohms. Heres what you do...Wire each sub with the + from one coil going to the - of the other, then you connect the empty + from one coil and - from the other coil to the box. Do this for both subs. This creates a 8 ohm wiring by wiriing it in series. Now, connect the positives from both sub boxes to the positive on the amp on one channel, and the negative from both sub boxes to the negative of the other channel. This is how it should be:
(same for both subs) BOX ------ + / - ------- + / - --------BOX
AMP+(left channel)-----both + from boxes
AMP-(right channel)-----both - from boxes

That is option number one by running the amp in bridged mode.

The other option is like you said: Wire up +/+ and -/- on each sub, then connect each sub to its own channel on the amp. I kinda like the first option better though, but thats my personal preference. I rather run both subs together and not on seperate channesl. I don't know if its bad or not, but like i said, its my preference.

 

Thanks for the info. I was wondering if I could do it that way. Now an added question. Would running the subs in parallel allow me to get more power to them since I would be having the amp in bridged mode? I want to get the most out of them without going with another amp. I believe this amp is sufficient since I've run solobaric's,RF punch powers,etc. with it without a hitch. I was just concerned if I did it the way I mentioned if they wouldn't really be playing to their full potential. The way you described seems like the way to get the most out of my amp and get the most to the subs. Thanks again, greatly appreciated.

 

I think to get the most power the first option is the best. I would run each sub into 8 ohms, and run both subs in parallel to get the ohms that the amp sees down to 4. You know what...this link might help you out... http://www.sounddomain.com/sku/ABNAW1000Q ...go to the where it says "Subwoofer Specifications" and youll find a link that says subwoofer wiring options.

Hope that helps.

Thanks for the info guys. Hey megabass those subs look pretty sweet. I'm not certain without looking into it but those subs have to be a lot better than the audiobahns I was looking at for a similar price. Are those the higher quality subs they offer? Also now that I've did some research myself here's what I'm down to. Running the subs in parallel. Each voice coil + connected to one wire and to the + of one channel of the amp, and each voice coil - connected to one wire and to the - of the same channel. Then the other sub connected to the other channel the same way. That would drop my amp to 2ohms which it is stable at and will get a little more power out of each channel doing things this way. The other option I've looked into is wiring the subs in series/parallel. I don't feel like typing out the whole schematics of that setup but basically after all is said and done both subs and all 4 voice coils will be wired up to one wire and to the + of one channel and another wire to the - of the other channel in bridged mode. The way the wiring is setup it will create a 4ohm load on bridged mode which the amp is obviously stable at. Given the power output of my amp as stated earlier which option do you think would get the most power out of it? Given the amp runs at 121x2 at 4ohms, it should be at 242x2 at 2ohms, each coil getting 121 watts. In bridged mode it will be at 484x1 at 4ohms, each coil getting 121 watts. Atleast that's what the #'s say. But how much does a 2ohm load vs a 4ohm load effect the amp and it's power output? I know this is a lot of questions but I just want to make sure I have this all planned out before I start buying everything. Thanks again.

 

I would still wire it the second way, which I explained. I would leave the amp in bridged mono 4 ohm. That way the subs are pretty much synchronized always. My thought is that if you wire them into two seperate channels, they might not hit at the same time due to the balance part of the music. I'm sure that you'll get more output out of it by wiring it in bridged 4 ohm. It doesn't matter what watts each coil sees, its what the whole speaker sees. The way it works is that your still getting 282 watts to each speaker, no matter what, but they are still synched together. I'm not an expert and someone else might be able to back this up.

 

i'd run it like the other ppl have already stated, with the voice coils in series and then the subs in parallel. the difference in resistances if 2 ohms had 500 watts then at 4 ohms it would be 250 watts. unless you have a multi-impedance amp like i do, but u probably dont' wanna spend the money for that.

 

Running those subs series/parallel is normally how I would do it as well. In fact, my subs are wired that way on my power 800.2. But remember you are going to be using two stealthboxes. Meaning one sub on each side of the car. And if you wire them series/parallel, then you will have speaker wires running back and forth across the back of the car. It might just be easier to run one sub per channel. Something to think about.

 

I guess I'd drop by to raise my post count.

 

That's what I was considering. Although they would be safe, I don't really want wires running back and forth across the car to complete the setup. Plus somehow I'm convinced the sound quality would suffer running wires back and forth 4 feet from each side of the car, maybe not though. I think I'll just run the subs in parallel off of each channel, that way things will be nice and clean. I was just curious if the series/parallel option would give me more with what I have. If it will sound similar, or the difference is minimal it's probably not worth it to me. I'm not going to competitions or anything. Thanks again.

 

Its the same thing in terms of wire length. Your not running both subs in series, just the voice coils inside each sub. Your still running a regular speaker wire to the amp from both ends. Its all in how you wire the voice coils on each sub inside the box. If you wire each sub to its own channel, your running the same length of wire, without having them go back and forth. If you were to wire the subs in series...then yes, you will have wires going back and forth. What you do by running both subs in parallel is connect the positives together and the negatives together on the amp.
