I didn’t want to remove the stock JBL amplifier and rewire a new amplifier so I improvised.
There was a small portion of me that thought only replacing the door speaker is with components that were higher wattage would sound a lot better and the highest amidst it but the bass was not there.
I was spending some time researching the best option to add a subwoofer to the car without again modifying too much the OEM harness. after removing the amp and measuring the clearance, I found a low profile small Built-in amplifier subwoofer for the Toyota Prius, that fits right underneath the passenger seat. Now I had the base that I was looking for the system actually sounded how I thought good or decent.
The head unit, not an American brand like Pioneer has some quirks. I haven’t received the OEM backup camera adapter yet and when I am on a phone call, I can’t open or do anything else on the head unit. The OEM GPS antenna connector I am also waiting on and I purchased a microphone to use with the unit as the built-in is useless.
With new door speakers, this head unit really makes the JBL system come alive!
A HDMI to RCA converter was also installed and connected to one of the en video/audio channels, this way if I ever need an HDMI monitor, I have one in my dashboard.
This radio with all needed connectors can be found on PriusOveranding.com
It’s a China radio with quirks but I love it! Also, it has 360-degree birdseye camera viewing in augmented reality.
