I am trying to design my sub box for my truck. I have (4) 8" DD608 D4 subs, which are rated at 300-600 RMS each. I'm assuming I can wire them series parallel down to 1 ohm. I believe I need a 3.25^ft box, with a 52sq" x 20" long vent, which should tune it to 35-40Hz, according to DD website.
I will also be running a 3-way active front stage with about 500 watts or so.
My truck is a 2014 Chevy Silverado Crew Cab, if that helps with my questions.
My questions are:
Will cabin gain come into play, such that I need to figure it in before I build my box? If so, how do I do that?
Can I manipulate the box tune to go lower, and should I, if I can?
What size amp, or amps would you guys recommend for the subs? (One big amp, or 2 smaller ones)
What will I need as far as extra battery or upgraded alternator requirements, if any? (I have done a big 3 upgrade with 1/0)
Any ideas on the best way to attach an MDF amp rack to the back wall of a truck without drilling any holes in the cabin?
As always, thank you for your assistance, and your patience with my ignorance!!!
