What to do

I am one of those people who had an suv and tried to get it loud for 3 years and then finally got a rex.
So let me tell you this, if you havent broken 150 in your suv, dont go buy a crx, it will be a HUGE waste for you. Im not cuttng you up, but obviously you have many more things to learn. CRX doesnt mean instant loud, i bet you wont be more than db louder in a crx than your suv if you just transfer all the gear, and maybe make a better box.
get your suv to 152'ish and then consider a crx. otherwise you'd be doing 151 WITH a crx, which is pretty hurting.
my grand cherokee did 151 with a single 10 and one 3k amp. guess what my crx did when i put the same set up into it? lol 151 db exactly.
with 2 10's and two 3k amps my jeep did 152.5, with 2 10's and same pair of 3k amps my crx did 153.5 (which is kinda hurting for a crx considering a Yaris can do 154+). This was all in 2007.
Only after I've gotten my jeep to do over 153 with with a pair of 10's I actually fully switched to the crx. I can tell you that at the most, a crx is 2 db's louder than any mid size suv with the same gear, and thats ONLY if you know 110% what you are doing.
get the escape to do 151 with one amp and 152+ with 2 amps and then consider a crx.

so yuli and brian agree.. work on the escape a bit more.. well my weakness is obviously my box since it isnt even meant for spl.. but building a box for the escape will definitely not work in a rex since their frequencies will be off by about 10hz.. sure you would learn from it but at the same time i'd be better off putting research into a rex

oh yah u dont put the same box in an suv as you do in a crx, thats a given. a crx and your car wont have a 10hz peak differance. you can always retune the box too. you'd have to make a totally different box altogether.

my peak frequency is 47hz right now.. (47 and 49 are very close but 47 seems best) figured a rex would be more like 60
i know my peak is low but like i said, its cuz the box i am using right now is meant more for daily..
imp of the drivers is dual 1ohm

the rex i built peaked at 59-60 hz. Makes enclosure design much easier because you can get much more port area and still fit the port length within the vehicle.
