    I recently upgraded the speakers in my 2017 Jeep Wrangler, but the power from the stock stereo just wasn't cutting it. I purchased this amp in combination with a couple of harnesses to easily plug right into the stock head unit. I have this amp mounted between the head unit and the glove box. This amp absolutely brought the sound system to life! Best bang for the buck. Oh and the best part is I didn't even have to buy an amp kit to wire to the battery. Easiest amp install I've ever done.
