Massive Audio GTX122

I come from the rockford fosgate family as far as subs those were my 1st choice. Bought these because i just wanted to try something different. And for the price its worth every penny. I came from 2 t1s and when i say these are neck & neck. Definetly buy again

GTX122

I love this sub it did well sealed but became a different beast once ported and even better once I inverted it, It has been in 2 cars of mine and still going strong. Massive GTX122 has been doing really well on what I would guess my electrical system is giving me close to RMS.

Not bad

Not too bad I only had them for two weeks... It doesn't bump as hard as I thought honestly even with the gain and knobs set correctly. But will do for now till I get some Rockfords.

Budget banger!!!

For the price you can't beat it. These subs definitely do thier rated power. I put these on my JBL GTO 1200.1 and they handle all my amp has to offer no problem. Planning on getting 2 more and running them on 3k rms.

Fantastic subwoofer!

I have 8 of these on a taramps hd8k 2 ohm version @ 2 ohms in a 16ft cubed ported box at 31hz. At full tilt on music I move decent air and it hits 147.6 db. Very loud and take rated power no problem. Would HIGHLY recommend!
