I got this a couple weeks ago and spent the longest modeling a box that would fit in a 1990 Chevy K1500 Regular cab, finally put the box together which took a loooong time, like 2 days non stop cuz there was alotta wood to cut and stuff and alot of problems i had to find ways to get around. I put it in and hooked it up at 2 ohms to a Sundown SAE-1200Dv1 after i did all the wiring and big 3 upgrade, and let me tell you, THIS THING POUNDS. It absolutely destroys deep bass and in a smaller cab its even louder. I would recommend this product to anyone for its price and quality. Overall an amazing product, i will definitely be buying RE Audio again. Only thing i didnt like was that the terminals required an allen wrench, which isnt a problem because it comes with one that fits, but it would be nicer to see spring terminals in the future
