Thought I'd share my other rides with the Crossfire family.1996 Dodge Ram.4 Atomic 5,000 watt amplifiers(2 amplifiers per subwoofer)10 Kinetik car audio batteries,2 320 amp Ohio Generator alternators,Eclipse head unit,2 custom built DC audio 15 inch subwoofers in a blowthrough enclosure.Pic of the box is a test fit;no gaps between box and truck bed after the install,accordion boot gasket so it doesn't leak.my best score so far is 159.6 decibels.There's more in there though;just a matter of fine tuning some more.
