UNBOXING: Massive Audio Hippo XL12 + SPL Test + Music Demo 

I put 2 of these in a VW GTI, powered with a 2,500 watts RMS Crescendo amplifier. I tapped out when I gave the owner a demo, but it really didn't sound that loud. Custom 4.5ft3 birch plywood box built by me. 10" Massive pro midbass in MDF/fiberglass enclosure (also built by me) with TW44 horns, 4 PRV 6.5" in doors on MTX Thunder 75 × 4

Love seeing new subs on the channel cant wait to see whats all in store also do you do box designs by chance

I had a pair of hippo xl 64 that I never got a chance to build a box for. I wonder how those would do.

I would love to see 1 avatar stu 15 on your channel or american bass hd 12 🔥

I got a 99 Durango. I can’t wait to put a high powered single sub in it. Biggest I had is 800 rms subwoofer. I like to be able to run a solid 1500 rms subwoofer that will actually run that. At least a continuous 1000rms on any given song. Ported enclosure. Then maybe, 6 Ten Inch subwoofers in my Santa Fe. Something around 400 rms a sub.

What the name of that app?

The best sub they had before boa came out was massive gordo 12s 15s and 18s hippo bows to the gordo they was not to be reckoned with.

nice video
