We are in the process of upgrading/replacing the head units/subwoofers/amplifiers/speakers in all four of our vehicles. This one went into one of my teenager’s cars. Since it’s an older model hiding the wires was easier. We’ve found installs are harder to do and take more time on newer cars. This car was a 2002 so it was easier. With that being said, you will want to buy an amp install kit to help do the job if you plan on installing this yourself. As for the quality, this honestly works better than some amps that I’ve used that cost twice as much. It really amplifies the bass well. The only thing is, and the reason this is getting 4 stars instead of five is because if you turn it up more than halfway it’s going to get hot. If you’re installing this keep that in mind and make sure there is plenty of airflow to the vents so it won’t get too hot. You may even need to run a fan. Other than that I have absolutely no complaints about this amplifier.
