mhuck123 Posted June 11, 2009 Report Share Posted June 11, 2009 Sooooo I am preparing to place my order for 2 fully loaded BTL 18's and I was measuring out my available space. This led me to an interesting problem, I realized that I have 5 MAYBE 6 cubes to work with after displacement (internal volume). I know that polyfill will work to some degree but I mean really is this even possible without sounding like shit!?!? It will be a "wall" completely sealed from the trunk and I have not purchased an amp yet so I am open but I really want to use the 2 18's. Anyone got any bright ideas!?!?! I need :hairtrick: !!!!!!!!!!!!! Quote Starting From Scratch!! Link to comment Share on other sites More sharing options...

David Posted June 11, 2009 Report Share Posted June 11, 2009 yeah way to small for 2, but perfect for 1 if your feeding them good juice (power) Quote Link to comment Share on other sites More sharing options...

What does anyone think is the minimum for 2? I do mean absolute minimum. If I redo the trunk mount and go with a fiberglass box to fit the contours of the trunk I could possibly get up to 7.5 total for both after displacement which is only off by 25% of the recommended volume. Maybe fill the shit out of it with polyfill. Anyone else?!?!?!?! Quote Starting From Scratch!! Link to comment Share on other sites More sharing options...
Beanz Posted June 12, 2009 Report Share Posted June 12, 2009 minimum for about two would be 10cuft and thats on the small side too Quote That's why they don't deliver. Yer ass better go sit along the side of the road and wait. You can't expect them to travel up some dirt road in a hick / back woods town. Thats how horror movies start I explain things very simply and use analogies in terms of Pickles, and grape drink, pool noodles and jackhammers...if you can't put 2 and 2 together there man, There simply is not much more I can do.

E a r t h Posted June 12, 2009 Report Share Posted June 12, 2009 cant do 18s bro. you are pushing it for 1 18'' alone. youll have more perfomance with smaller woofers in that space period Quote Link to comment Share on other sites More sharing options...
mhuck123 Posted June 12, 2009 Author Report Share Posted June 12, 2009 Well I guess then I am going to have to do a shit load of fab work then that I was trying to avoid. It's gonna cost about 5 grand but I want the damn 18's in there and if I completely redesign the trunk hinges and do a custom fiberglass and wood enclosure I can squeeze out over 10 cubes and then fill it with polyfill and get the level of bass I'm looking for. Anyone know if with the right amount of power (full rated RMS is what I'm planning) I can get a hairtrick with just 2 18's? Quote Starting From Scratch!!

If you somehow make enough space for those subs, and tune it low in a good enclosure with good power and voltage, you better do a hairtrick lol. :hairtrick: If I were you, I would stick to one 18, build it an ideal box for the amount of power your giving it, keep voltage up, and you will be plenty loud.

E-Train Posted June 12, 2009 Report Share Posted June 12, 2009 Personally with 2 BTL's I would never run polyfill with as much as you need to push those 18's might make a little heat Quote 1997 4 Runner Alpine CDA-9886 4 Fi Audio X Series 12's 1 Crunch GP3000D Pro DC Power Inc.

David Posted June 12, 2009 Report Share Posted June 12, 2009 I did 9.5 cubes after displacement on 2 BTL 18s with around 8kw on them they were fine. Quote Link to comment Share on other sites More sharing options...
