brsteinbach Posted December 23, 2009 Report Share Posted December 23, 2009 (edited) I am building a box for a friend of mine and I need some help/advice. Well first they are 2 8" subs from a couple house speakers (he doesn't listen to a lot of rap). They'll be powered by a Dual 2 channel bridge at 4ohms so he'll get about 150wrms. But I need to get the most I can out of these 8's. The problem is it is going to be in a Chevy Ex cab but it's going under the seat so I only have 20" of width 9" of Height and 13" of depth. That is max guy's so I need help, I wanna give him the best output as possible so I was thinking a small circle port tuned to around 40-45hz? Any advice appreciated, Thanks guys.

Bad thing is I can only get a little less then 1 cube.

BanginOnABudget Posted December 23, 2009 Report Share Posted December 23, 2009 why dont u do a quarter wave that slides behind the drivers seat? does he have many people in his back seat? heres a vid of my kicker 8 in a quarter wave. Quote im taking out my passenger seat, battery is disconnected, going to unwire and take out the three amps, take out the 70+ lb box, then the platform so i can crimp 1 wire. Almost as bad as those fegs that put those horns in their grills and roll down the street distorting the block.... 1990 Jeep Cherokee 2 Dr. Big-3 in 0g on Stock Alt. Pioneer 6.5" and 5.25"s temp. until i can afford the new crescendos. Pioneer 6000ub Reciever NO amps at the moment. SA-15 on 1kw coming soon. MSG Me for a free enclosure design!!

AI James Posted December 24, 2009 Report Share Posted December 24, 2009 first off you have 1 cube and 150rms, your nots going to be getting much sound out of 2 in that space and power, best bet is to run 1 and make the best box you can in that space which will suck too in the space you have total. second they are house speakers they are probably full range 8s rather then dedicated subwoofers Quote Link to comment Share on other sites More sharing options...
basshead4life Posted December 24, 2009 Report Share Posted December 24, 2009 couldn't you put a box under each seat? Quote Team S.M.D. Maritime Car Audio- (2) 18" SSA ZCON D1 - American Bass 500.1 - 60 ft of 3/0 -480 Ah of battery - (2) stock alternators (70 +90) - Kenwood Excelon x-794, 4v preouts car audio is just a LOT more complicated than "this amp does this power" or "this sub will be this loud". its like 2 + 2 = banana. (if that confuses you then you get the point) lol Link to comment Share on other sites More sharing options...
OrionStang Posted December 24, 2009 Report Share Posted December 24, 2009 just do them sealed... keep it simple This, since he doesn't listen to alt of rap and probably isn't looking for the LOW lows.
