Custom Trunk enclosure specifically made for the e92.
One of the best ways to make sure you get the bang in the cabin with no rattles.
Not to mention the awesome stealth/OEM look!
Sub is JL 13TW5 sub
Amp is Massive Audio 1000.2 amp
Works perfectly and bangs hard.
Comes with special harness for hifi logic 7 connection, all necessary wires/fuses/cables.
Direct plug and play. You need nothing extra!
PM me for price.
Otherwise I will continue to enjoy this amazing setup.
