hi guys, i have a ford explorer and im debating etiher putting in 2 15" soundsplinter rl-p's in a ported box, 7 cu ft tuned to 28hz, 92" sq. of port area. Or doing 2 18" Rl-p's in a sealed box at a total of 8-10 cu ft. Either would be running off a soundstream pca2000d amplifier putting out about 1500w or so. i've never done anything this big in car audio so i was wondering if anyone had any knowledge on what my advantages and disadvantages would be
you have an explorer so plenty of room for a box 14 cu ft.. go with 2 18s ported! im guessing your wanting to be just as loud as possible, so go with that. i would say the choices you said would be very close in output, but the sealed box will sound a little cleaner, but if your going big you want to go big, i know when i jump in a car with big subs and when i hear it doesnt pound i get disappointed and think wow thats it for 2 18s.. do it big with 2 18s ported so when people jump in they jump right out because it was just too much for them to handle. thats the right way to do it! good amp too is that the one with dual inputs for power and ground?
i'd like to have some room still to haul things, so im limiting the box to those sizes. i know ported boxes are much louder on the low end, but i just love the ideas of 18's and have never had sealed. i figured the 18's would compensate for the sealed design's poor low extension? correct me if im wrong
The ported 15's would have a better chance of metering higher if that's what you're looking for. 2 18s sealed would still be fairly loud and sound good. I agree with cwruck though, when you tell people you have 18s there will be that wow factor until the guy with less subs pulls up next to you and is louder.
With my experience with the RL-p, I agree with Troy. The smaller 15's ported, will probably be louder then the 18's sealed. The RL-p is more at home in a small to mid size ported box.
my picasso 2000d got a cold solder spot on it after about 3 mths however a vehicle in my country uses 10 of these on 10 15" Treo ssx & it sounds KILLER , it never goes on the meter since all the owner cares about is music playing but its the loudest sound vehicle i have ever heard
i wonder if MS is thinking about the short lived picasso 3500D which had faulty power supplies & was recalled ...
11.5 might work, i would try a little bigger if possible. but 100 sq in of port is no where near enough, you want 12-16 sq in of port per cu ft, so thats less than 9 per cu ft
