Excellent sound quality

I hooked a pair of these up to a AT60.4 and I was very impressed on how loud and clear they are on that.....i can't wait to see what they do on an AT125.4!!!! Very high quality and shallow mount so it's easy to put just about anywhere.

Great sound

Very happy with my purchase. Will be buying from CT Sounds again very soon

Stratos 6.5

Shipping was fast,installed speakers,they sound wonderful,going to do a review on my YouTube channel,will buy more for my jeep and lexus


Had this amp about 2 years now and man let me tell you this amp is beast. I killed my old old DD9012 only because the sub was old. Now I'm running it on a SQ HDC.3 12" and it's crazy windy in my single cab truck anyway great amp highly recommended
