are they DVC or SVC subs?

from what i'm reading they are non-bridgeable amps, so your wireing choices are limited.

the words that say "these" are hyperlinks....but my amps are bridgeable, cuz it says it on the + and - s on the amps..it says bridge....but on he subs. scroll down in the hyper link it has all the info.

It wouldn't matter if you could bridge the amp or not. It is not rated for 2 ohm bridge so your only option is to place the subs on seperate channels. The left channel for your left sub and the right for your right sub. You will only be getting 90 watts rms to each sub. Unfortunately, that is what I had with my dual voice coil sub last year. I didn't have the money to upgrade my amp and was stuck for a year with a bad pairing. You will benefit with the fact that you have two subs opposed to my single. But you will either need to upgrade the subs or amp later. Since you have a underpowered sub, be sure to place the subs in the most efficient box as possible. I like the sound of sealed, but you loose alot of wattage them. I noticed you have a phaze switch on your amp. Nice option but be certain to keep it on normal phaze unless you experience a large drop in frequencies.

the site says they cant be bridged...what gives with that? they can do 2ohm stereo but not 4ohm mono? i doubt that, must be a typo. they can handle a 4 ohm bridge, like you said the amp says you can.

if you posted the right sub, they are single 4 ohm subs. so i dont see the problem in bridging a amp for each sub. or maybe mikegett saw somthing i didn't and they are dual 4's or single 2's.

mtx subs are under rated, 360watts rms wont hurt those subs if there in good condition, especially if you like sealed boxes.

so basically....bridge the amp and run + to + and - to -, then wire the other sub and amp seperatly doing the same thing.

ok well if your positive they have two sets of posts then that link up there is wrong..........and as far as your pictures 2 & 3 would show your amp a 8 ohm load which you dont want to do, and picture 1 you are going to be running all channels at 4 ohms so that seems like the best out of what you showed me......

with a dual 4 ohm sub, you can wire it to 2 ohms or 8 ohms. 8ohms and you wont get much power, 2 and your amp will most likely shut off and go into protect.

so really, your only option is to do what mikegett said, and just run one voice coil to one channel of the amp, one voice coil to the other side, but like he said, thats only 90x2 for each sub...not a whole lot, but i think you should be able to push them if the amp has bass boost, if not maybe your deck has a "loudness" or somthing to that effect, because you'll want a little extra punch.

since you'd basically be running them in stereo, make sure the amp is set to mono, if it doesn't have that option, only run 1 signal wire into the amp and split it (you have a red and white, split the white and run both "whites" to one amp, both reds to the other) that way your voice coils wont be trying to do different things at the same time.


you could grab a multimeter and ohm out the voice coil just to make sure its 4 ohm nominal, if your lucky its actually a 2ohm sub. because right now you'll get just as much power running 1 amp as you will with 2.

Sorry about the first post. I thought you had the single voice coil from your link and one amplifier. Unfortunately, if your subs are dual voice coil it won't matter. You will end up with the same situation just as Mike2002 stated. The MTX site shows these models available for that sub. They only made dual 4 ohm and 4 ohm single. They appear to be a pretty nice sub. I would suggest posting the two amps on ebay and see if you could get enough for one 4 ohm mono amp rated at 800 watts rms. You could then wire the subs coils down to 2 ohms and the subs themselves back up to four ohms.

T8104A 10" Subwoofer 4 Ohms 24 Hz-150 Hz 800 400/800 84.2 dB 2 1/2" 102 oz. 5"
T81044A 10" Subwoofer Dual 4 Ohms 28 Hz-150 Hz 800 400/800 84.3 dB 2 1/2" 102 oz. 5"
T8124A 12" Subwoofer 4 Ohms 24 Hz-150 Hz 800 400/800 86.6 dB 2 1/2" 102 oz. 5.625"
T81244A 12" Subwoofer Dual 4 Ohms 24/150 Hz 800 400/800 86.5 dB 2 1/2" 102 oz. 5.625"
T8154A 15" Subwoofer 4 Ohms 24 Hz-150 Hz 1000 500/1000 89.5 dB 2 1/2" 102 oz. 6.938"
T81544A 15" Subwoofer Dual 4 Ohms 25 Hz-150 Hz 1000 500/1000 90 dB 2 1/2" 102 oz. 6.938"

I apreciate all the help seriously. I don't know alot about amps, subs, and ohms and all that jazz. This helps a bunch. How i have my speakers wired I have them wired like the picture in number 2 I have a speaker running to each amplifier, and the speaker is wired in a series. (picture 2). If i get rid of my amps. I would need a mono amp? I am not sure what this is. maybe some suggestions to running these, mind you I plan on runnning 4 of these subs in my trunk. What would be the best amp for this. thank you.

My buddy usto have 2 mtx thunder 8000 12's he had a audiobahn amp and was pushing about 1500rms to them, i would suggest an amp with the ability to do i ohm stable, pushing about 6-800wrms at 1 ohm.
In small sealed boxes they should sound good.

Have you purchased the other two subs? If not, will they come from the same person and be the exact model? Your choice on amp or amps will deepend on the amount of voice coils the new subs will have.

I have 4 subs now, I went to my buddys store and got them today, I have 4 now of this same model all in 12" inch cubed sealed boxes..so i plan on building a fiberglass to mold them all together.. but yeah, just what i want to do is maybe get two mono amps to push these four 10" inch subs...that sound right..mono amps?
