Great subs and box

The subs sound great. They deliver the perfect amount of bass I was looking for. Well worth the money for sure

Way worth it

The photo is when I first got them had to much stuff in the car lol. But I got these not knowing about the 8 inch subs and I just wanted something small and that will perform I had to 12 inch subs and these 8’s out perform them and look better and save space but I’m only running a 500w amp because that’s all I have but it still is way better then what I ever thought they could be so I give this a 9/10 rating

Daniel Bramstedt
Love ‘em

Fast delivery and they sound amazing I’m going to save up and get another set for my other vehicle and fits perfectly in the back of my Yukon

Greta little speakers!

Got these at a great price online. Read reviews. Gave them a shot. Have them running on a JL500/1. After some tuning and positioning them for the best sound in my Excursion, yes, the biggest SUV ever made, they sound great! Hard to believe that much bass comes out of that small of a box in such a large vehicle. I’m very happy. May get one for my other car too.
