2 15's hitting 150's daily on music isn't going to easily happen. You'll have to push the subs too hard and for long listening periods shit will get stinky and fail.
Why not step up to 2 18's or 4 15's as cone area is your friend. You want to overbuild: meaning lots of cone area and plenty of power, so you're not running on the ragged edge. Tis way different to burp then to play loud for long periods of time.
Sleepy is set up for daily. Plays low and sounds good. He can play all day long and does 148+ and "sounds" louder to the ear. It hurts to sit in his car //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif
I just thru 4 15's in a wall in my Altima. Box is way too small and on 1500 per sub I did a 149.7 and I could push the subs hard all day long on that kind of power in that small of an enclosure.
What does your current set up do on the TL? What's the loudest vehicle you've heard? I ask because the 2 I mentioned are fine for 2-3 minutes at a time, but no way in hell could you sit in them on full tilt for any real amount of time.
