    MTX is a great brand it's the brand that I choose
    I have two sets of these Terminator 12 inch sealed boxes connected to my Jh1500.1 MTX jackhammer series amplifier inside of my 2012 Toyota sienna and I definitely be thumping sound quality is absolutely amazing no matter what genre of music that I play in the future I plan on adding two more boxes that will eventually get me to a total of 8 12 MTX Terminator haven't decided the final configuration for my final own load but I will definitely make this happen I've only had one minor issue one of my boxes made of cracked and it's giving me distortion at the moment think I pushed it a little too hard with this exceptionally powerful amp and the things not even turned up

    Ported these subs and DAMN, these things POUND!!!
    I put these two subs in a pro ported box, and they f****** thumped hard. I was blown away at the quality of the sound. I had the mtx thunder 500 amp, and the pro ported box swap was the huge WOW factor. I was amazed !

    Best budget bass package from Sonicelectronics and price!
    I can’t believe the amount of bass for this price and how small the enclosure is and the subs and box enclosure looks great, I would buy again!

    Amazing Budget System
    This is a great system for those that are just wanting to add a some “oomph” to their car. For what I paid, these sound amazing in my wife’s Camry.
