MTX TERMINATOR tn 250-1 mono 400watt max
 
I just ordered this amp for my two ten inch kicker comps and i already have the kickers in my truck box, the box came with a terminal on the left and right sides, i am just using the driverside terminal and have piggy backed of the drivers side to the passenger side for a mono amp, my question is the mtx amp although a mono has a two channel output? do i just bridge this for maximum power or just use one channel? thanks

I'm sure someone else that might have a for sure answer, will answer you..
I THINK that mono amps with two sets of outs are just one chanel split two ways (in side the amp.) and no different that just running two pos/two negs out of a single speaker out.. it's just done inside the amp...

at least that's what I think I learned here on this forum.... lol...

Re: MTX TERMINATOR tn 250-1 mono 400watt max
 
So can i bridge it to just a straight mono amp?

Vegas is right...Ignore the fact that the amps speaker outputs look like it's 2 channels, it's only like that to make wiring easier for certain applications.

I'm not sure what you're kickers are (2 or 4 ohm, or SVC or DVC), but you're amp isn't stable at 1 ohm, so here's you're wiring options:

If the speakers are DVC:
Series/parallel = 4 ohm load
Voice coils wired in series, speakers wired in parallel
http://images.the12volt.com/12voltim...m_dvc_4ohm.gif
This shows a 4 ohm speaker, but if yours are 2 Ohm, it'll just produce more power, either way, this is the only way you can wire it with a DVC set up and your amp. If you wire it the other way, the Ohms will be 1 or .5 and your amp cannot handle that.

If the speakers are SVC:
Parallel = 2 ohm load
http://images.the12volt.com/12voltim...m_svc_2ohm.gif
If SVC, wiring the speakers in series would result in a higher ohm rating and less volume output.

DVC=Dual Voice Coil where your speaker has 2 spots to connect speaker wires to.
SVC=Single Voice Coil where there's only 1 spot to connect speaker wires to.

Ok the kickers are 4ohm so how do i wire them for 2ohm and get 200watts through each channel?

oldblue72c10 01-09-2012 09:15 PM

Re: MTX TERMINATOR tn 250-1 mono 400watt max
 
Because it is a mono except split for two sub hook ups straight of the amp. I have two kickers in a truck box with one terminal on each side for each sub.

are the subs "single" or "dual" voice coils? you might not want to "piggy back" you might be under 2 ohms that way but can say for sure since I dont know enough about your subs

you can not get 200 watts per sub with that amp you can only get 200 watts RMS total @ 2 ohms

This is ONLY possible if your speakers are SVC...if they are DVC, you're only option is to wire them at a 4 ohm load.

If your speakers are SVC, just connect speaker wires from the amp to the terminals and it will be wired as 2 ohm.

If they are DVC, you'll need to pull the speakers out and run a "jumper" from 1 negative to the other coil's positive, and connect opposing +/-'s to the terminal and then hook up the amp just like the above (see the diagram I posted for 4 ohm load).

I thought the way it works is that if the amp puts out 200 watts at a 2 ohm load, it will be 200 watts to every speaker it's hooked up to as long as it's a 2 ohm load...am I wrong?

it depends on the amp this amp states 200 watts RMS x1 its a mono amp regardless of how many speakers you hook up its still x1

now if this amp stated 200 watts RMS x 2 it would be per channel for a total of 400 watts

Ok guys sorry, i didnt state that it is a single voice coil here are the specs on the amp.

MTX TERMINATOR tn-250-1 mono 400WATT

Primary ratings-
4ohm rms output: 100w 1 channel
signal to noise ratio (1watt):>73db
Secondary ratings-
2ohm rms output: 200w 1 channel
THD+N (distortion)(1watt):<1%
Frequency Respionse(-3db):20HZ to 85 HZ
maximum input signal: 4V
maximum sensitivity:200mv
crossover: 18db/octave@85 hz lp
bass boost: switchable 0,6, or 12 centered @ 40hz

its not a 400 watt amp thats peak power witch really means nothing the RMS rating is the constant wattage it will produce in this case 200 watts RMS x1

you should never buy an amp by what the "max" or "peak" power rating is, its really is all about the RMS rating ask around or maybe some one else will chime in.

if you look on the MTX website it does not even have the peak wattage listed only the RMS, dont get me wrong its not a bad amp its just not what your thinking

Re: MTX TERMINATOR tn 250-1 mono 400watt max
 
Cool...then all you need to do is connect the wires from the amp to the terminals on the box! This is where the amp's dual terminals would benefit you since you can use 2 wires and it will still be wired at 2 ohms so the speakers will be getting 200 watts.

Re: MTX TERMINATOR tn 250-1 mono 400watt max
 
Thanks guys im new to audio. So do you think this amp will be a decent amp for two ten inch svc comps? and does this mean each sub will get 200watts?

its hard to answer that LOL, if you like a lot of bass that hits hard then its not going to feed your hunger, its all about what "You" want not what I like this amp will only put out 200 watts x1 so its 100 watts per sub

oldblue72c10 01-10-2012 08:15 PM

Re: MTX TERMINATOR tn 250-1 mono 400watt max
 
Well it better put out more then the stupid jensen 100 watt two way its replacing due to the jesen exploding haha

oldblue72c10 01-10-2012 08:16 PM

Re: MTX TERMINATOR tn 250-1 mono 400watt max
 
And when you say 200x1? its a mono but has a two channel hook up?

if you was happy with the Jensen amp you will probably really like the MTX amp its better quality and more true power

the amp is internally bridged and the 2 terminal hook up is just to make hooking up the subs simple

Re: MTX TERMINATOR tn 250-1 mono 400watt max
 
Yeah the jensen wasnt too bad i mean it got everyone in the parking lot at schools attention i had it bridged and then piggy backed of the 1st to the 2nd sub

Each speaker will share the 200 watts bridged power. Now, the kicker is how good of a box you have. If the box was not built to spec for the Q and appropriate breathing for your subs, you won't get exactly the sound you want. In all honesty, do not expect a ton of bass from two 10s in a truck box, unless you make done adjustments:

Add an electronic crossover to enhance and multiply the low frequencies, tune for the low pass, and cut the mids and highs. Then use the rest of the crossover to tune the bass out from your mids and highs, and clean up the signal. Remember, garbage in, garbage out...make sure your head unit is a good one, and you have ground loop isolators to eliminate alternator whine, and you will be good
