[QUOTE="RMDecker, post: 8846233, member: 689162"] My GF has a a 2019 Jeep JLU Wrangler with the standard head unit. We wanted to insall a sub and amp yet keep the stock head unit for the time being. Also for theft reasons as its often without the doors. (the cargo area locks). I have installed the SoundQubed Active 5-Channel Car Audio Line Out Convertor. [URL]https://soundqubed.com/q-loc5-active-line-out-converter/[/URL] . Ive cut the wires that come from the head unit to the speakers and run them to the line out converter. Then the amp to the speaker wires. With the converter installed nothing plays from the head unit speaker outputs. What I have discovered is on power up the head unit looks for a resistance from the speakers before turning on that channel.

Can anyone tell me what effect a resistor will have on the sound and their thoughts on the value of the resistor? amplifier is an Audopipe 5ch amp and it doesn't have line level in. [/QUOTE]
