  • As a customer I would have asked for the un aesthetically pleasing sound material so I could sound good now instead of later

  • Why would you put a false wall when you want the most bass to go through to the front? That false wall is just another obstacle for the bass to penetrate. As pretty as it may look, physically it has no place in helping bass output to the front. WASTE OF TIME AND DUMB IDEA!!!!!!!!

  • 😳 no sound test

  • Idk why they couldn't do the big 3 upgrade and the sound dampening .More labor costs for the customer, instead of just having everything ready when they come back

  • Man I wish you guys would've dropped a Link to where we can still Buy those ol' skool JL Audio W3's in the description! My friend had those same ones in a Bandpass Enclosure, an Alpine Amplifier, and like 4 gauge Wires. It was a Good, Clean install that I can remember. Oh yeah this fool was running like 12 gauge speaker wire too. Overkill? I think Not Lol

  • Looks good. But if im ganna spend that kinda money imma need my shit to bloe the trunk off. Those subs arent making any noise. But hey he could prefer ot that way

    bassheadray 03/24/2020 5:20 pm Reply
  • Never orient your subs this way in a trunk. Aim them upwards they will sound way better and way less if any fart.
