Hey, I am adding two 8s along with an amp and cap to my existing bose system. I have all the wiring as well as the hi.lo converter. I was quoted by Zippos on Route 22 in Plainfield, NJ for $140 to install everything. Can anyone tell me if thats a good price, or should I go elsewhere? Is there anyone on this board in NJ who would be willing to install my stuff for a cheaper price? Thanks.
