This plug n play is absolutely amazing. Super simple to install and no need for any additional wire running throughout the car. Used it on my 2019 Rav4 XLE.

I replaced the factory speakers in my 2010 Prius with new speakers that were connected to the original BLU LOGIC ECU DSP. However, the new speakers couldn’t receive enough power, resulting in distorted sound in the right speaker only. I spent weeks troubleshooting the issue, but the PUZU solution was a game-changer. It provided a perfect solution at an affordable price. Thank you for your help.
