DB.sickest.kid Posted November 27, 2012 Report Share Posted November 27, 2012 Ok I have a setup in my 04 gmc extended cab. It's 2 dd 9515g in a pwk box that's tune to 28hz. I have a single dd m3a pushing the subs. My question is would it be better to.do 3 15s or 2 18in? And what feq. Should the box be tuned. The catch is I don't want a wall. Any info or input will be grateful. Ps everything is stock in the electrical department but will upgrade Soon. So have another dd m3a that I can strap Link to comment Share on other sites More sharing options...
john253a Posted November 27, 2012 Report Share Posted November 27, 2012 it all depends on the sub and what u want to active? Link to comment Share on other sites More sharing options...
Blackedout Posted November 27, 2012 Report Share Posted November 27, 2012 3 15s = 530 sq inches of cone (about) 2 18s = 510 sq inches of cone (about) Both of these setups are going to take a wall to get the proper airspace. If you can't build a wall, stick with 2 15s. Trunk Build Log Link to comment Share on other sites More sharing options...
TeamHT Posted November 27, 2012 Report Share Posted November 27, 2012 Incorrect. I would do three 15"s. I don't have extensive experience with DD equipment, but I built a box for three 15" BTLs on 12,000 watts 10.5^3 net 14^2 port per tuned to 35hz. Only up to the window line sub forward port up in an 03 Silverado extended cab Tell me...does this smell like chloroform to you? Link to comment Share on other sites More sharing options...

Bump4life Posted November 27, 2012 Report Share Posted November 27, 2012 ^^ that one. 3 15s can kick. more power handling. but if you are going with DD 9515s you gotta run more than 1 M3. id consider 3 m2bs or 3 m3bs even. maybe 4 m2bs strapped up somehow.

Bump4life Posted November 27, 2012 Report Share Posted November 27, 2012 problem is for that setup you need a minimum of 10.5 cubes net with a shit ton of port. 4.5 net per sub would be bettter. so 13.5 net plus your port.

n8ball2013 Posted November 27, 2012 Report Share Posted November 27, 2012 and tune it higher. 28 hz tuning iwth DDs just goes to confirm my thoughts with your box designer.
