ive always used nothing but the best brands, and i like to switch things up quite a bit so i though i would give 2 of these a try in my 08 silverado. at first i was hesitant but after hearing these in my truck, i was blown away by the sound clarity and bass these sub give. great sound quality with excellent deep bass at the same time. i am using a orion 800.1 on them. awesome subs,especially for the money. i put them up there with the jl w6's with the right box. you wont be disappointed.
