i got mine done at Division R, monterey park.

they're off of the New Ave. and Valley Bl. intersection, across the valley bl from JR cafe. installation price: $70. (HU, subs, amp, all wiring)

i got all my shiet donated for free so i didn't have to worry about cost. they sell their products for quite high. the install price and quality is good though.

email me if you still need more info. i rarely check my pm.
