If you do actually want to play music from it, do not tune so high. //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

CRX's don't peak above 60 hz. As a matter of fact, they peak at 53-55 hz stock.

i was wondering... i didn't think they peaked that high but idk much about resonant freq of vehicles tho either.

what they're saying in laymen terms:

if you plan to compete strictly with vehicle: box tunning should be rather high (40+ hz) straight competition vehicles will tune to 55ish hertz and posts good numbers; the draw back is a large peak at the freq its tuned to and in turn results in a not very musical setup.

for daily use/abuse: tune in the 30's, dependant on tastes/music: anything from 30-40hz will result in a good daily driver( for the most part)
