I have a non-GPS, non-JBL system, which has

Bluetooth Phone connectivity
Bluetooth Audio streaming
AUX input
USB input
With steering wheel mounted controls for audio and phone

It has good features but the audio sounds just really bad, So I was thinking of upgrading the amplifier and the speakers. Without changing the head Unit. Has anyone out there done this upgrade and how did you go about it. Inputs will be really helpful, thank you.

 

simple, your local car audio shop will have a peice that connects to your factory radio, and has outputs for your amp. cost about 70 bucks for the peice alone. they started making this peice when they added the controls to steering wheels. anyone who changed the factory radio loss the usage of the controls. i havent done this to mine yet, but with install of that peice and wires for the amp i was quoted at 150 for my 07 let me know how it goes

 

does anyone know what that piece is called ....

 

its called a line output converter.
