MTX Audio JackHammer JH4512X2D

Jackhammers 12"

These are some sick subs hit hard in my bronco. I will go bigger next time because my car is big and needs big subs but if you put these in a small car these subs will blow everyone else out of the water. I say get em they r worth the money!

They bump in my trunk

i have had many beginner subs since i got my first subs, but these things are something else! the moment i connected these, they started shaking my entire car! i was like "WOW! my car has never rattled before until i got these bad boys".. i recommend these to any one starting out ...this box is all quality!

Great subs, so so box

Im sure this box would go good in a car with a trunk, as for me i own a hatch back and it just didnt fit my personal taste with the position of the vent, so ive made a new box, owned the subs for about 1 1/2 years now in a daily driver and i am NOT nice to these subs.
they will float out but ive never managed to make them distort or rattle.

these subs are wonderful i've never regretted buying them especially for the price, they punch pretty hard, and i suppose depending on your vehicle/set up still have quite a bit of clarity (remembering this isn't rated in there box)

the box shown looks fairly well built, not divided internally.
i suppose this is fine for a mono block but i like some depth\clarity to my system which is kinda hard to get on this set up, i'd recommend using a separated box, i've had these in ported, sealed, and that vented box, the subs do pretty good either way.

Makes my whole car shake!

Have this enclosure in my SX4 along with a MTX 600XD amp. Excellent sound and products from MTX. Makes everything in my car shake and vibrate! I see why this item is usually out of stock. But Sonic is quick to replenish their supply. Am more than happy with this product and Sonic customer support. Would recommend both to anyone. Thanks, again Sonic!!!

Bumps!!

I thought the low RMS would be junk but they bump so hard! They mad my whole car rattle. My trunk door was literally pumping in and out. I love these!!

Great subs

I had this company subs from last 6 years and i had best experience with these ones and this company and now i am just searching for jack hammers just love them.

ive never had a ported box before

so i have never had a ported box before, generally sealed and one probend comp RT bandpass box.

so far this is my favorite box . i had the jackhammers on an RT500D mtx amp.
