87accord Posted June 25, 2009 Author Report Share Posted June 25, 2009 yes two 18's i still have not done the 45's yet so i dont know how much that will use up Quote new system in the works (3) DC lvl 4xls 15's (one of three are here) (2) DD z1 (done) old kenwood four ch 4 runs of 2/0 (done) ? 200 amp alt may two ??

1976 Silverado Posted June 25, 2009 Report Share Posted June 25, 2009 yes two 18's i still have not done the 45's yet so i dont know how much that will use upok well sorry but did a bit of searching and came up with nothing. The 18 Fi BTL is .26cft displacement. And they are close to each other on the specs so that SHOULD give you SOMETHING to work with. Sorry that its not exactly what you wanted but hope it gives you an IDEA of how much space it will take. Quote Link to comment Share on other sites More sharing options...

1976 Silverado Posted June 25, 2009 Report Share Posted June 25, 2009 thanks for that what do you think about my air space should i throw another layer of 3/4' mdf on itdo you mean on the inside?.. to reduce the amount of air? or on the outside for extra support? if its for the support i say just brace it properly and it should be fine.

1976 Silverado Posted June 25, 2009 Report Share Posted June 25, 2009 yes on the inside to reduce the airspacewell at 19cft and with the 45's you could make it around 18cft (just make them beefy). then with lets say .26 per sub thats .52cft.. which will it make it a total of 17.48cft which should be ok.. after all suggested spl is 8cft per sub. but thats just recomended (please someone with experience with dc subs chime in if im incorrect). so the extra .75cft should be ok for the subs.
