I'm giving two stars only for price that's worth one extra star other than that it gets one. My tech guy put this 10"sub together with a sound ordnance box and a mrv-m500 alpine amp to add to my wife's factory system in her 2013 dodge srt8 superbee package. First off with seats not folded down no base gets to cab of car! Which means you can here the bass better from inside the house than in the car! I've poked pin holes in back dash and took rubber material off where factory sub mounts in back dash if we had beats package. After doing all this and buying run knob and still couldn't get bass to cab moving box facing up down backwards forwards didn't matter. Just to find the other day it had a rattle so I turned up the alpine amp from nominal to 3/4 and heard blown rattle clearly rated for 250 rMs @4ohm the amp can only produce 300w at 4 ohms so should never have blown since I never turned gain to full power and broke sub in at nominal never pushing it hard once thru 20hrs listening break in period. So I would spend an extra the extra money per sub and get a product that does what it says!
Pros: Great price
Cons: Great price cheap crap won't handle RMS EVEN WHEN PAIRING AMP SAME BRAND!
