    This subwoofer is very well built and looks amazing. I haven’t had the opportunity to install yet since I’m waiting on my box design but I know it’s going to pound!!

    These subs surprised me. I never knew an 8 could sound like a 12”. These little guys are not to be taken lightly. I have a SKAR 2000 watt hooked to them and it’s not even keep up with them. Very unrated speaker at 800 watts

    I have 4 in a gately underseat box in a 2014 ford f-150. Wired to 1 ohm on a scv2000d. Still breaking them in but they hit the low notes well. I was surprised that some comments were saying that they were not an all around musical speaker. I listen to rap,rock, pop and country and these little sundown's do it all well. Not sure if it's just the Gatley box or what but I am having good all around sound. They are not earth mover's! But they do get low and loud.
