EXPOSING a Cheap Subwoofer w/ Rockville K9 Version 2 vs V1 | Blowing Subs on 1000W & Best SPL Test?

#Subwoofer #Bass #CarAudio
It's time to expose the truth behind the popular Rockville K9 subwoofers! We all remember last year when the infamous version 1's came out, right? They ended up having lots of problems with defective voice coil enamel shedding off, then blowing smoke on rated power. So this big question is... Will the new K9 version 2's perform any better with improved glue, or will they get stinky all over again? After all, that 5,000 watt peak wattage rating makes me a little nervous! So let's find out shall we!? They supposedly improved and upgraded the 10", 12" and 15 inch woofers with bigger and better voice coils! But.... we'll be the best judge of that!!!

$100 Budget Subwoofers Tested:
W10K9D4 10" 3200w = 134.3 decibels @ 56hz (prefab box)
W12K9D4 12" 4000w = 141.9 db @ 40hz (custom ported)
W15K9D2 15" 5000w = 140.3 db @ 40hz (prefab box)
