bassrace Posted May 6, 2011 Report Share Posted May 6, 2011 And you would want you ports on the same side. i would say for 1 sub i wouldnt put the ports on opposite sides. I would do a 6" port or two 8" but thats just me Quote 145.9@40hz 145.3@34hz big 3 X2 group 34 Deka Group 31 All 0/1 awg jl meta wire Alpine CDA 7894 Orion HCCA D5000 2 AQ HDC312's Crunch gpv1100.2 (for 6.5"s only) AQ pro audio 6.5" - 3 sets AQ supertweeters - 2 sets 2000 Slamry Link to comment Share on other sites More sharing options...
bassrace Posted May 6, 2011 Report Share Posted May 6, 2011 Alright with 2 4" straight ports the lenght would need to be 8.132" long and 2 4" flared ports would be 9.132 long thats tuned to 35hz with 5 cuft for the box. Btw 35hz will kill the lows with these subs! I have 2 hdc312s in my trunk rite now tuned to 35hz and murder the lows Quote 145.9@40hz 145.3@34hz big 3 X2 group 34 Deka Group 31 All 0/1 awg jl meta wire Alpine CDA 7894 Orion HCCA D5000 2 AQ HDC312's Crunch gpv1100.2 (for 6.5"s only) AQ pro audio 6.5" - 3 sets AQ supertweeters - 2 sets 2000 Slamry Link to comment Share on other sites More sharing options...

bassrace Posted May 6, 2011 Report Share Posted May 6, 2011 Well if they are flared make them as close to 9.1" as you can and like i said you can use pvc pipe and save some money and flare them yourself(there vids on youtube that will show you how b/c theres diff methods). Or you could just buy the ports. Justmake sur to seal around the ports real good with silicone or some good glue. And yea i would put the ports right next to each other. You could do sub facing the back of trunk and ports facing drivers side or subs to back of trunk and ports to the back of trunk all on the same side. This works best in my camry.

bassrace Posted May 6, 2011 Report Share Posted May 6, 2011 O and make sure that the ports arent getting suffucated try and leave atleast 5" of clearance to the wall theyre facing( it shouldnt be a prob if the ports are on the side).

Well I tried flipping my box around and having the subs facing the back of the car, it didnt make them louder but made them not as loud. The box is squeezed in there so theres not that much room for air to flow into the cabin of the car so thats why I think they're louder facing the driver. I'll probably buy some 9" ports and put their holes on the opposite side, ports facing the back. Ill put 2 ports, one ontop of the other, 9 inches long.
