hey right now i have 4 12in memphis power references in a sealed box. i am powering it by a jbl bp1200.1 right now the amp is turned down quite a bit becuase i am over powering the subs they are only rated at like around 250 each. I am not sure what to do with setup, i am thinking of a few ideas. either porting the box or adding 2 more 12's and jsut going with 6 sealed. I might even be able to port the 6 12's, so if i could would taht be my loudest setup? And also i know taht just adding subs and not giving them more power is not gonna really be louder but if i added the 2 more 12's and turned my amp up alot more would i eliminate that? thanks alot

If you added more cone area and more power, you should have a noticable increase. If you also went with a ported box you would gain that much more. Just the box would make a good bit of difference. ------------- Nik

ok ya so i guess im deff. gonna port the box but now would recommend going with 4 12's ported with my 1200 watt amp turned down even more cuz now the box is ported or going with 6 12's ported with the same 1200 watt amp but just turned up more. would the 6 be louder then the 4?

are you going to have the correct ohm load with the 6 subs?

don't know. maybe wiring each sub in series to 8 ohms & then running all in parallel to each other. not sure what ohm load this would achieve. does anyone know how to configure this?

Look to the left of the screen there is a woofer wiring section.

ya ill prolly go with the a little over 1 its like 1.33 i think which means i would get more out of the amp then im gettin out of it now. so what should i do port 4 or 6 with the same amp?

go ahead and wall off your dakota with 4 15" PR's and port that box at around 38 hz. You should be set there. Also buy a HO alternator and a yellow top for under your hood. Keep the amp and your set.
