yep I run it daily like that, its a little edgy on the bass notes when playing rock...sometimes doenst play the real low lows on rap very well (like lower than 30hz) but when kickdrums kick around 50 hz, your vision blurs. Ive had pretty high end systems in my cars for the past 20 years, and this is the first one that gives me a headache when I drive around with it turned up any....my inner ear actually hurts after a while.
I did a MECA extreme competition over the weekend (won 1st place too) where they let you do whatever music you want for 2 minutes and take rolling averages by two mics in different places such as the kick and the port...and the 4hp did the 2 minutes flawlessly and never got hot even though I was throwing all my amp had to give at it. This is a well made woofer, TC Sounds FTW //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
I'll be putting the 4hp up against the RE MT here soon, i'll post pics and stats of how each did and the variables for them.
