  • GREAT SPEAKER!!!!!
Size: MTX 10" 35 Series 4ohm 250 Watt RMS Subwo...
One of the best things about MTX, is they consistently underrate their products. This sub is " rated " for 250 watts rms and 500 watts peak, but can easily handle 300 watts rms and around 600 watts peak. For those on a tight budget, but still wanting to add great bass to their car audio, I definitely recommend this sub. ... show more

  • Dont Go Above RMS
Size: MTX 10" 35 Series 4ohm 250 Watt RMS Subwo...
Ive had 2 of these subs for about 8 months, and the first 6 or 7 I only had a 550 watt amp hooked up to them and they sounded pretty good, but i thought they had more in them so i upgraded to a 1000 watt amp. After about 2 weeks one had a power cable melt off the push terminal for it, which I fixed myself. Then a week later, the other one did the same. Now they don't quite sound the same as they used to but i've just decided to get a different brand now. ... show more

  • Check serial number
Size: MTX 12" 35 Series 4ohm 250 Watt RMS Subwo...
The sub I received had a sticker on the back claiming only 200w RMS, so I checked with MTX, and they verified the serial matched a 2021 model which is rated for 250w RMS. if you get one that says 200, check with MTX

The reviews speak for themselves. A new design that's ready for years of heart pounding thunder. I'm running two of these at 300 watts rms each in a sealed enclosure that has approximately .6 cubes of space per side. In a nutshell...I'm over the top satisfied!!!
