I want to upgrade my headunit, add in front/rear component speakers, and a subwoofer but unfortunately I have the JBL system in my 03 4Runner. :bash:
Is possible to power my front and rear speakers with an amp and have a separate amp for the subwoofer?
Do they have to rewire the whole sytem? Strip the truck and start from scratch pretty much?
I've been doing a lot of reading but I am rather confused, do I have to buy the Metra Toyota harness designed for the JBL systems or buy the regular harness for the SR5 4Runner?
I'm not sure now if its even worth it upgrading everything now after my research. Worse case scenario, I just upgrade my headunit, buy the Metra harness designed for the JBL systems, upgrade the speakers and buy the Soundgate Line Out Converter, add in my amp/sub and call it a day.
