This is a build i did a while back for my father van. just had pics of the bulid laying around on my pc an said i'll put it up there to see wat u guys think of it. Box is .75cuft before port and speaker displacement tuned to 35hz. center console also holds the switches for the power locks and windows, switch for strobe ligths and a stinger voltmeter for amp.
a few weeks ago we change out the rockford p18" and put in the new REX 8"
the RF played louder had fairly good sq,played the hi notes well but on low notes the bass seemed lacking. when we switched to the RE, it was a day and night difference with the low notes. it plays well in to the 20's with power and controll,u could actually feel the seats vibrating when the lows hit.The sq is grate, plays other frequencies powerful as well.
