custom sound system includes everything you need to install and play, ive had this system in my 135i for about 6 months and i just recently sold the car so i need to sell the system now as well. the system is composed of:
Digital design 10" 3510 series sub
digital design 1000watt amp
custom light weight enclosure
all wires needed for install
and a brand new optima yellow top battery
total msrp for this system is well over $1200 but since i need to sell ill take $600. my lose is your gain. the system still has a 8 month full warranty. i use to have a JL w7, but replaced it for this sub, this sub hits harder and cleaner than anything else out there.
