I got two DUAL 2omn speakers and i just need to know best way to wire them for a mono block amp. i have them wired parrallel in the box

you need to wire each sub down to 2ohms then wire them together like the one in this pic http://m.seimg.net/product/img/subwoofer_wiring/2_subs_DVC_4_ohm_mono_variation2.jpg witch will give you 1ohm so you will be getting every bit of power that amp has but you should get a bigger amp for thos speakers

need more info,what ohm load are spkrs? are they single voice coil or dual? if dual what ohm dual 2 or dual 4? what amp are you planning to use? stereo amp or mono block? if mono block what make and model? what style box are you using,sealed or ported?

If you need further help, I’m available over the phone at https://www.6ya.com/expert/stephen_fa62cb6d50fe05e8

this is a mono block amplifier ,both positives are the same inside the amp and both negatives are the same ,there is 4 terminals to make it easier to wire 2 speakers . Use either positive and either negative ,with this speaker ,inside the box you can wire both positives together and negatives together (parrallel) this should be 3 ohms and the amp should run smoothly ,maybe a little warm but that amp can take it .

The Soundstream Class A 5.0 will deliver its full power at 1 ohms mono.
I think your subs are two dual 4 ohm voice coils.
If you wire the voice coils for each sub in PARALLEL, that's 2 ohm for each sub. To get 1 ohm mono, you need to hook up the subs in PARALLEL to the amplifier, in bridge mode. That's the way to get to 1 ohm mono. Please add a fan to your setup as the amplifier will get very hot. You will need to use a relay to hook up the amplifiers and fan(s) to or you will damage the remote ouput of your HU (if you hook up the fan straight to the remote of the HU) as the remote output of the HU is not designed for the amount of current a fan draws.
Good luck. If you need help with the relay issue, have a look here: http://www.caraudiohelp.com/newsletter/multiple_amplifiers.htm

run it all series and bridged

it all depends on what kind of box the mtx subs are in as far as wiring the subs. The best way would be take the speaker wire from both sub boxes and run the positive into the right positive then the negative into the left negative. and run 8 gauge wiring kit to the amp because 10 might be to small and 4 is to big 8 gauge is perfect for this amp.

If you are wanting to run them bridges, I'm going to assume each voice coil is 4 ohms, then what you want to do is as follow


+1 -2


+3 -4


So on the diagram here, I know its silly, but you'll hook a wire from lead 3 to 1, that will bridge the positive side dow. Then you will hook a wire from lead 4 to lead 2. From lead 1 and 2, run your speaker wire to the terminals on the box. Now if you have a mono block amp, its not going to affect. If you have a 2 channel amp that is bridgeable, be careful. Some amps are not 1 ohm stable. Try and see. Good Luck.

4 ohm voice coil? on the mono amp it should be from left to right ++ -- you want to go + x x -

Your amp based on what you say would have no problems whatsoever with an 8 ohm load, not even if it actually has dual 4 ohm coils and you wire them in parallel giving a 2 ohm load (don't know your particular sub).

Every good car amp has protection circuits to prevent itself or the speakers from damage from too low loads so it shouldn't be a problem even if you screw up with your calculations. A good amp should even be capable of dealing with a dead short on a channel, zero ohms, activating protection of course.

Good luck and don't worry!

Te dual inputsm are tied together on the output side thus having a "MONO" amp. Most class D anps are stable down to 1 ohm (check your manuel) therefore, 2 2ohm subs are a 1 ohm load. 2 DVC (dual voice coil) 4 Ohm on each voice coil will give each sub a 2 ohm load so 2 dual4 ohm V's will give you a 1 ohm load as well. Parrallel all conections.

What subs do you have? Is this amp 1 ohm ono stable?
