Cavy vs. Sunfire - My friends Cavy with 2 sealed 12's on 750W had more in-your-face bass than my Sunfire with a ported 12 on 1500W. Mine was louder at most frequencies but I still prefer Cavy bass, it feels like the sound bounces off the dash better. 154.2 at what frequency?

have you considered switching to a single 15" that might solve the cone loading off the motor issues and also move more air... i know my single 15" did 154.2db more than 2 years ago... all equipment in the trunk... and only 2 group 31 optima batteries with engine off
Well to be honest I have no idea what the tuning is. I believe its starting the high 50's lol

dude... measure the car for me.. Ill design something... but you gotta step down a level in subs..the motors are just too big! they totally kill the back wave and too much compression on the cone thats why you're blowing out the surrounds

measure from the trunk lid furthest point to where the sensor goes in the front windshield

then give me dimensions of the lagest box that can fit in your trunk
