Powering a sub and all door speakers without replacing the stock entune head unit?

Finally have the door speakers, tweeters and sub installed. Sound deadening added to doors and behind the rear seats. Night and day difference even without the door speakers amped. I went with a kenwood 8 inch sub for the premade truck enclosure and this thing is loud.

Cant wait to install the key amp to finish the whole process.

 

I'm sure you will hear a world of difference between where you are going and stock equipment. Changing the speakers alone makes a big difference.

 

Does anyone know of a line out converter with the adjustment knob that will t into the harness? I'd like easy on the fly adjustment for my amp

 

This is not something you would want to be adjustable on the fly. Amplifier input signal is a set and forget. Set your amplifier sensitivity on the amplifier when you install it and use the volume knob for fader. Otherwise you’re just asking for trouble.

 

I added tweeters, door speakers, a 10" sub, LOC, crossovers, a bass knob and two amps all while keeping the stock head unit. Visit the "My Audio Build" thread to see my build and how I did it. Not easy, but doable. This is on my 2014 so your 2019 might be slightly different.
