I highly recommend getting a male and female wiring harness for this thing so you don’t have to cut any factory wiring. (Metra 71-1761 and metra 70-1761 for my car.)
I replaced my factory speakers with kicker speakers and I just wasn’t able to drive them effectively with the stock head unit. After installing this, I can easily fill my car with clear powerful sound. It’s a bit pricey for what it is, (2/3 the cost of a new head unit) but if you want to keep your radio stock, it’s the best option to get useable sound out of the radio.

He told me he can make it work and that the amplifier itself looks new but this is poor practice considering the amount being spent on a "new" unit.
