| How do you install amp and subs to a stock headunit?
hey
i just got my 2002 330ci about 4 months ago, and i just went out the other day bought 2 10's (700w each) and an amp (1800w). i just want to know what I need for this stuff to get installed into my stock headunit, and then afterwards some direction on how to install it. i need 4 gauge wires and a line in converter i think? is there anything else? if anyone can help me out and tell me what i need and give me some installation tips that would be appreciated. thanks |
