Ordered a few months ago along with a Meso 8" subwoofer. This thing is heavy so I know it is going to push the Meso 8" beautifully! CT for the win.

This amp pushes

This 900.1 pushes out way more than it claims 👍🏻, this amp strokes the hell out of my 2 12s and gives them a hell of a workout. I recommend this amp to anyone who doesn’t want to spend a lot of money on a big amp this amp throws down!!! Worth every $ spent on it. keep up the good work CT Sounds👍🏻👍🏻👍🏻

The amp works great

I'm pretty sure it puts out more than it's rated power at 1 ohm.

Built like a tank

Solid Build. Haven't pushed it to its RMS yet but sounds great.

Tropo xl 12 inch

These subwoofers are by far the best product I've bought. The price for the performance is staggering and i need to line more panels in my car with hush mat because of the rattling. Definitely a recommended product and planning to purchasing some 6x9 meso series.

This thing pounds!!

I love it and I am waiting for an amp to be available to go with the sub!!! Kicker has some competition!!

Nice

Super fast and nice

The Best Subs for the money period

Bought two tropo xl 10 d4’s wired them to 1 ohm on a 1000 watt amp. These subs have exceeded every expectation I had for them in every aspect Coleman Thedinger is doing great things for the CT Sounds Community. Looking forward to many more of these great products.
