jballin2010 Posted December 12, 2011 Report Share Posted December 12, 2011 ok i got two 18" Fi Q's in a 15cuft box in my ext cab. tuned at 30hertz. i am running them off one Alpine MRP-2000 at the moment (which is 2000 @ 2 ohm), but I wired the (dual 1) subs in series-parallel for a 1 ohm load, which is 'unhealthy' for my amp. So whats the best one amp set-up for my system? or should i get another alpine and wire them at 2 ohms a piece to separate amps? really wanting a single amp setup though (and may possible upgrade to BTL's later, so i need some extra POWAA down the road!)

I have mine on a Soundstream TX12600.. it pushes them pretty damn good and is .5 ohm stable. Buy one of those and then if you upgrade to (2) BTLs then you can just buy another amp and run one amp to each sub.

jballin2010 Posted December 14, 2011 Author Report Share Posted December 14, 2011 ok thanks guys. . . and also, my subs are bottoming out on me now anything below 30 and im wanting killer lows in the 28-23 range. tips on achieving this? i have four 4in PVC pipes, two on both sides, cut to the correct length (based off 12volt.com). could it be the amp? box? port? . . . . .

bassrace Posted December 14, 2011 Report Share Posted December 14, 2011 (edited) That's not near enough port area for a 15 cuft box..... Give me your dimensions on the box and I'll give you some suggestions.... Edit: if you are at 15 cubes then you would need something like 12 4" ports to be in the right port area range....lol that would be super innefficient imo. Maybe more like 5 6"? Or 3 8" Edited December 14, 2011 by bassrace 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...

jballin2010 Posted December 14, 2011 Author Report Share Posted December 14, 2011 what about 4 6" diameter ports. . .that way i could just widen the already cut holes now. just a thought Quote Link to comment Share on other sites More sharing options...
profundus-sanus Posted December 14, 2011 Report Share Posted December 14, 2011 4 6's would work just fine. Quote Link to comment Share on other sites More sharing options...
