well if your worried about space dont get a rex! thats why I'm getting rid of mine. 155 on the tl isnt worth it unless you are competing. but I always took a pop-up,2 chairs ,big charger, my weight cans for the pop-up,laptop, meter,cooler,power cords. thats not including amps, box ,changer,areo ports mounted external etc etc shoot it's a tight fit and the car would'net play music that loud because the amps were at such a low load.
but if you want to compete in street a,b,c a crx is a great start. dont expect to get alot of help with them either. most of the stuff that wroked for other people wont work for you in most case's. ive had 2 crx's both were 89 si's and a 154.7 with 4 messed up konaki 12's was the best i did. it was loud as hell but played music like sheeeet. anyways goodluck with your purchase and future build pm me a link to the build thread and dont be scared to put sound dampening in that car //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
