I bought 8 of these subs for a wall build. I had all 8 in a pac man style wall center port tuned to 33Hz powered by 2 Audiopipe 1500Ds and did a 149.x with stock battery. I later installed 2 Kinetik HC1800s and 2 runs of 0ga and did a 152.4 on the dash on TL with driver window down. They are the best bang for the buck sub on the planet!

I Bought four of these and only have three of them in a box because I could only afford a box that fit three and it still knocks i got three of those and 2 other twelves and two 10s plus my two 10inch mid range and 6 tweeters and after market 6x9s in the back. all in my ford windstar. soon enough im gonna build one big box to fit in the back of the van and put all my subs in it and itll bang pretty good. i only got two amps. one for the highs and one for the lows so im going to have to by another amp. and itll deff be from here
