How's it going guys, I am doing my first system, and i have worked with Dj equipment for a while. i Just bought 2 Orion HCCA 12.2. I own a 2000 BMW 528i. I just bought also a pioneer 4100 dvd cd player. i researched that these speakers are best ported.i have decided i want to use 2 sundown 3000 or atomic 3000. i am also ordering tomorrow a High Output Alternator and using extra batteries "optima" One for each amp.
so the advice i am looking for is my trunk is completely sealed and wanted some advice on what to do for a box and get bass out of it, i guess i need to build a custom box, so what specs do i need to tell someone to build it, and also do i just port it through the ski trap? i dont need the trunk so the whole trunk can be gone.
I would invest in a better battery if you plan on doing one per amp, like one Powermaster D3100 or Kinetik 2400 per. I would seal the box off from the trunk with the subs and port facing forward. Others more familiar with those subs may be able to help you with exact size and tuning.
yah i have gotten alot of people telling me that for the batteries, but im getting the optima batteries dirt cheap so thats why i am going with those, ill try them and if i have to change them i will.... soo are you saying a sealed box is my best bet? or port the box but keep the trunk sealed?
have both subs and port facing forward into the cabin, but seal the rest of the box off from the trunk. Yes, port it.
I replaced 5 optimas with 3 d3100s and they hold my voltage much better. It may be cheap but what if you need twice as many batteries? Good luck with them.
