I have a 2017 Toyota Corolla and will be using the stock radio. My question is what kind of line output converter should I be using if I am using a sub amp, 4 channel amp, and a Clarion eq?
If you are using the clarion eq. You can use just one quality loc. Run that into the eq and pull your sub/front/rear from the eq. I'm not sure of the audio system in the corolla and what frequency's are sent to each driver. You may need an loc that sums the signal and does a little restoration to get good sound quality and for it to perform as you want
