Our GTX Series subwoofers are rated at 250-1000 watts RMS / 500-2000 watts MAX power with a 1.5-2.5" voice coil configured for dual 2/4 ohm impedance. All GTX subs use tight Red stitching that’s sewn through a UV treated non-pressed paper cone onto a EROM foam surround. Then it’s bonded to a heavy gauge steel basket that’s bolted to double stacked high flux Y30 70-150oz Strontium ferrite magnets with a 10mm top plate. Then everything dances on a springy poly cotton spider with high powered woven tinsel leads that connect to spring loaded 5-way binding nickel plated speaker connectors. These woofers scream sound quality and truly represent Massive Audio's commitment to value and performance.

  • Would you have any speaker recommendations for a 1997 F350 CrewCab? I have a new receiver that's great now I really need some good sound. What I have isn't bad but it needs something better. Thank you for your time and help.

  • can I use the GTX122 - DUAL 2 OHM SUBWOOFER in a 1997 F350 crew cab?

    You can use this subwoofer in any system but it requires a box so the space needed would be your only unknown. We have different suggested box sizes in the manuals that you can view on this page. 

  • This comes with 2 speakers or just one?
