loganuf Posted April 14, 2008 Report Share Posted April 14, 2008 I wanted to ask you guys what you think about adding two more 12's to my current setup. I currently have 2 12 inch L7's in a 6 cubic ft. ported box, and i wanted to know if i could add 2 more 12's in the same box? I was gonna add them 2 the top of the box. You can see my box in my profile pic....im not sure if i have enough room in the box or not, i hope i do cus i dont want to have to build another box, so if you guys have any suggestions on how i could make this work i would appreciate it.

dmanson Posted April 14, 2008 Report Share Posted April 14, 2008 it might get a lil bit louder but no as loud as having all four of them in the proper size enclosure. you'll need at least a good 10 cu ft for four 12s Quote 2-DC 15XLM2 D.7s 1-DC 5K amp (1) XS Power D6500(UNDERHOOD) and (1) XS3000(REAR) 3 runs 1/0ga for power and 2 runs of 1/0ga for negative.

PaulO2288 Posted April 14, 2008 Report Share Posted April 14, 2008 Dont do it. Then you wont have enough air space for the subs and your probally be louder with the 2 you have no with that because its deffintally not enough box space for 4 12"s. For the 2 12"s that really good. You would also have to get another amp also, more wireing etc. Quote Link to comment Share on other sites More sharing options...

My friend did it and he lost 3 dbs. Box was way too small for it, box is louder subs back port back, amp ohm wont make sense and 2 subs up and 2 subs back dont do much either. Your better off getting as much potential as you can out of the 2 subs you have now. My suggestion would be to get a better amp. Something that pushes more power and really lets that box and postition get the most out of it. Quote Link to comment Share on other sites More sharing options...

If i do it im gonna do it right and just build a new box and run one of the same amps that i already have. I'll make the box like 10-12 cubic ft. and have each sub gettin around 750 rms....i just gotta figure out where im gonna get the money to do all of this lol Quote 2000 Eddie Bauer Expedition: Alpine CDA 9883 2x 18" DC lvl 4 D2 10.7 cu ft box 33hz knu 1/0 wire amp: Kicker ZX2500.1 Kinetik Link to comment Share on other sites More sharing options...

PaulO2288 Posted April 14, 2008 Report Share Posted April 14, 2008 Like you said another amp. Around 12 Cubic feet for the box, well built and designed box and you should get good results. Quote Link to comment Share on other sites More sharing options...

cichlidfort Posted April 14, 2008 Report Share Posted April 14, 2008 anyone with any suggestions on how the box should be built? I saw all 4 subs facing up with 8 4 inch aero ports facing the back tuned to 32 hz.

PaulO2288 Posted April 14, 2008 Report Share Posted April 14, 2008 Your going to have to do subs up port back to fit all the subs. What kind of music do you listen to? And any chances of the meter or want it to get really loud for the meter? Quote Link to comment Share on other sites More sharing options...
