hi guys. I'm getting ready to add amps and a dsp to my 2018 SE non jbl. im wanting to get a plug and play harness for the radio. so i can avoid splicing into wires. i purchased an amppro 4 ap4-ty13 cause it was plug and play and im able to get optical out for the dsp. the problem with the unit is that it is for camrys with factory amps. my Camry doesn't have a factory amp. unless its different for non jbl units. i didn't see an amp under the passenger seat or behind the radio. is there any plug and play harness solution out there?
