ok I currently have 3 12" JLs in a sealed box. My box is messed up due to moisture from when i strip my jeep down. So I'm looking to build or buy a new box for my 4 door 2014 Jeep Wrangler JK. I have a few questions first. 1. Sealed or Ported? 2. Upfire or downier? 3. Should i just use 2 or can i use all 3 again? 4. Should i add horn to the box? Im looking for a good sound with some good bass i listen to all types of music. Also, want it to hit hard when someone tells me theirs will hit harder than mine lol. FINALLY. i want to continue to have good bass even once i strip my jeep down and its all open. Thanks for your help in advance.
