Add another $650 in labor thats what I paid. Sometimes you have to pay for quality work and products. Cheaper is not always better. I had the exact same amp wired into my TSX and those fukers butchered the hell out of the wiring. It had knarly engine noise and sounded like shit. He of course blamed the cause of noise from a faulty amp. This same faulty amp is now in mt ILX. No Engine Noise at all. I could have probablt put in Kicker Components and still be happy but I'm really happy with the wide range that Hertz provides.
