skavenger Posted November 8, 2009 Author Report Share Posted November 8, 2009 It's right on the FI website btw- Sub displacement(18" BTL) = .26ft3... Kinetik makes very good batts but tests have proven that XS does perform better with direct drop in testing. I'd also look into Northstar(which is what I run now) and I was very impressed with the differences after I switched from kinetik.Btw what vehicle is the 18 going into?? I'm hoping the Tahoe because in the Altima it's going to be very very tight if that's the route you're going. If so I'd suggest just sticking with a 15 in there or running an 18 that can still perform well in smaller boxes like a Sundown Nightshade. but ive made the box thats in there 2.9cbft .1 short of recommended an id like it to be louder on the 15 in there now..its louder but id like louder http://www.youtube.com/watch?v=HzHkPv149hQ http://www.youtube.com/watch?v=HA83EeTzZeI Quote Link to comment Share on other sites More sharing options...
Marlo Stanfield Posted November 8, 2009 Report Share Posted November 8, 2009 That is a very small box for a that 15, especially on only 2000 watts. If you just made an enclosure like 4.5ft3 @ 34hz w/ 65in^2 of port you would likely see a significant difference in output. Just by raising the efficiency by making a bigger box + more port area you should see a pretty big difference. Trust me spend $30 first to see what kind of output you can get from the 15, before you got out and buy a bigger woofer. It seems like you won't have enough room to build a proper box for an 18" BTL or the power to counteract and inefficient enclosure. Quote 1998 Ford Explorer Eddie Bauer... New setup, old ride...
