MTX Mono Amps
 

Anybody have any experience with these amps?

thanks

yep, which model do you have or are you wondering about?

MTX Thunder X 300
i want to pair it with a 10" MZS 1004

i believe the amp is 200 watt RMS at 4 ohm and the sub is 150 watt RMS.

thanks for any help

MTX makes excellent equipment and the combo you're looking at is compatible.

thanks for the reply.

as a matter of fact, i called MTX this afternoon.

i asked if this pair would be a good match and the sales rep said not really.
he said that the MZS 1004 is a single voice coil sub and that the X Thunder 300D is better suited for a dual voice coil.
he said that for the MZS 1004, the best matches would be the TC 3002 or the TC 2002.

Do you agreee?

I checked the amps that the rep at MTX recommended to me for the MZS 1004. Its wierd but they are 2 channel amps. Why would he recommend a 2 channel amp for a single 10" Sub?

I also downloaded the manual for the MZS 1004. In the specifications, it says 150 - 300 Watt RMS.
In a case like this, what wattage should the amp be RMS.

Thanks for any help on this

it may be a two channel amp but he likely plans on you bridging it, with mono amps to get them really working you need really low impedence most two channel amps make there max power bridged at 4ohm. most people here are likely runnng amps that make alot more power then the subs are rated for, but wither way try to atleast stay to the high end of the power range.

My single 12 is rated for 600RMS and its getting around 700RMS

I dont understand why they would rate the RMS with such a big gap.

It does not even state what the peak is!

Should i be looking for a Mono amp that puts out 300W RMS for best results?

Thanks
Jazz

it doesnt state peak because peak is kind of a mythical creature, RMS is the amount the amp can continuously deliver and the amount the sub can continuously handle :) the minimum number is the minimum recommended, under powering is often worse then over powering...

If you plan on staying with this sub forever then yeah something that maxes out a 300RMS will be fine, what you will notice when looking at single channel amps is that they have ratings for 4ohm 2ohm 1ohm and when you get into the real high end stuff they have .5ohm and .25ohm ratings. If you plan to run one of these subs then look for something that makes around 300RMS at 4ohm, and if you are buying a mono amp you'll be much better off in the long run when it comes to adding more/bigger subs, because as you increase the amount of drivers or switch to different voice coils you' ll beable to wire to get more power out of the amp, alot of 300RMS at 4ohm are often also rated around 600RMS at 2ohm, etc etc. this way you can stay with the amp as your system grows and your demands increase. Instead of having to buy a new amp every time you want to change up the subs :)

Great response, very informative, thank you.
The sub that i am looking at is a single voice coil. How does this come into play when looking for an amp? I dont really know how its different from a dual voice coil.
Thanks
Jazz

dual voice coils allow you to wire for different levels of impedance, it also changes the level power of you can use, if one voice coil is rated at 300w then two of the same in a sub let it handle 600, more power more sound, basically. Also when you have 2 4ohm voice coils the sub is wired for either an 8 or 2 ohm load depending on if you wire the voice coils in series or parallel, and if you only have one then you can only produce a 4ohm load. i hope this makes sense its 5am i just woke up hahahaha.

Example, my amp makes the most power at 1ohm, so i got a sub with 2 2ohm voice coils this way when i wire it parallel it provides a 1ohm load to the amp allowing me to get the most power possible from it. with the 2 voice coils i get about 700rms out of the amp, if i only had 1 of them then id only get about 350w.

ohms are the level of resistance created by the voice coil, the lest resistance the more power that can flow, but not all amps are 1 ohm stable and alot of multi channel amps are only 4ohm stable. it's not to tricky to get a handle on, there are lots of right up on the web about, just google 'ohms' and find something related to audio, then do some reading up, a good understanding of this will be a big help through out the entire time you spend with stereos.

There is no doubt that i will not be upgrading. The single 10" will be staying there for a long, long time. Therefore, is it safe to say that i should buy a momo amp that puts out 300Watts RMS at 4 ohms?
Thanks again
Jazz

if you plan is to stay with the one sub you'll likely find it cheaper to buy a 2 channel amp that can be bridged at 4 ohms, find one that makes around the 300RMS mark when bridged into 4ohm, these are generally much smaller the mono amps and you have to understand that a mono calls d amp rated at 300w at 4ohm is more then likely designed to put out over 1000RMS at one ohm so its gonna be like $1000 there are some small single channel amp you could consider..

Here are some examples of what to look at getting.... some are 2ch some are mono... just read the specs for them and you'll get an idea of how the 2ch stacks up next to the mono


MTX Thunder TC3002 2-channel car amplifier 75 watts RMS x 2 at Crutchfield.com
Rockford Fosgate Punch P325.2 2-channel car amplifier 80 watts RMS x 2 at Crutchfield.com

Alpine MRP-M500 Mono subwoofer amplifier 500 watts RMS x 1 at 2 ohms at Crutchfield.com

also when buying it might not be a bad idea to browse the classifieds on here... there is some kick ass gear for ridiculous prices!!!!! plus then you get the info on how it would work from who you are buying it from...

That would be why the TC3002 and TC2002 were suggested for 300 Watts RMS and 200 Watts RMS (respectively) when they're bridged at 4 ohms.

shameless plug...

That amp would work beautifully.

It will be cheaper to buy a 2 channel that will do 300 watts rms at 4 ohms then it will be to buy a mono that does 300 watts at 4 ohms. However, if you are planning on adding another sub, then you will want to look for that mono that can do 300 watts at 4 ohms for upgradeablility.

Ok
I have narrowed it down to 5 amps that i can get locally for my price range.
They are all 2 channel amps like most of you suggested.

1. Exile X300.2 $199 CAD 300W Bridged at 4 ohm(seems like alot)
2. MTX TC 2002 $183 CAD 200W Bridged at 4 ohm
3. JBL GTO 75.2II $183 CAD 97W Bridged at 4 ohm
4. Phoenix Gold Octane R252 $139 CAD 150W Bridged at 4ohm
5. Pioneer GM 3300TT $112 CAD 150W Bridged at 4 ohm

Which of these seems to be the best deal?
They will be powering an 8" single coil 4 ohm sub of 150- 200 Watt.
I will not be adding more subs in the future.

Thanks
Jazz

get the mtx, it seems to be the best bang for the buck, and thats whtat you have been looking for so it's probably the one that will keep you the happiest.

The Exile and the MTX would be your best choices (MTX is a little less expensive for similar "real" power)

Are you changing your woofer now? You had posted it was an MTX MZS series woofer (handling 300 watts RMS).

i to noticed the driver change, it used to be a ten inch to i thought.

yes, after much measuring and pondering, i can only fit an 8" in my Corrado. I will build a custom box that will fit behind the shock tower. The box will have a trapezoid shape. space is VERY important to me.

i made a mistake in my earlier post, the JBL GTO 75.2II is 290 Watt Bridged at 4 ohm. its 97 Watt x 2 channel.

i have read a few different reviews online regarding the MTX TC 2002. More than one review complained about overheating.

at this point it would seem that JBL, MTX and Exile are in the lead.
the things i read about the MTX overheating has be concerned about going with that choice.

not sure what brand of 8" sub that i will purchase as of yet.

Thanks for all the input

Jazz

For an 8" sub look at Elemental Designs 9kv.2 Its getting only positive reviews, is designed for small enclosures and is a great price. I believe part of their business runs out of Quebec as well.
