1: Thank you for READING them... We get so few that do!

2: They can't. That cabin is so small, relative to those wavelengths, it's an impossibility if they are all phased correctly. How do you have your woofers wired presently?

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

i would think a ramcharger would have plenty of room maybe your thinking its a pick up its like a K5 blazer just dodges version. im not trying to be a pain or rude but most people dont seem to know what a ramcharger is.

any ways there dual 2 ohm hooked to a kenwood 900 wired to 2 ohms at the amp since kenwood amps arnt really 1 ohm stable (tryed it with a set of dual 4 ohm subs)

do i really need to go as far as a wall in this thing i really dont want to because i like to see out my back window lol the total room in the back that i have is 5 foot wide 42 in high and 6 foot long

i know what a ramcharger is, when you had all four of them in and you said you were getting cancellation, which way were they facing and were they all in separate boxes? 2 subs per box? one big box? you dont need a wall to get plenty loud in that truck, just the right box and you can make them all fire upwards and either port upwards too or port to the rear. if your subs are in prefab boxes right now thats probably half of your problem. oh and you can get the SPL meter by doing a search for Term-Lab meters

ok sorry about qestioning you about know what the truck is. i have 2 boxs with 2 subs in ech box custom built to memphis specs. i tryed facing them up, stacking them one on top of the other, one behind the other and every time they sound like total crap all most like there blown and 6x9s could pound louder lol take 2 out and its loud so loud it hurts a subwoofer ventrins ears. now i have be installing systems for years but never did a 4 sub setup ony 1 - 2 - and 3 sub setups all side by side facing the same direction and never had this problem. but of corce i cant put all 4 of these side by side.

try this, put all 4 subs back in and wire one box backwards and see what that does.

i should give you some more info on what im trying to do. im starting my own bizz and using this truck so people can hear what my subs can really do. but at the same time if some one wants there subs right after they hear my setup i can take 2 of them right out and put them right in there car. that seems to be the best way to sell these subs since all the kids around here only know the cheapo wallmart brand subs lol i mean i had a set of 14 year old 12" crossfire subs rated at 200rms ech and that was about the loudest any one around here has ever heard. lol
