Connecting amp and sub

I am new to Audio. I’m about to add sub and amp to a factory system and I’m wondering how to wire this. I've read this article https://soundrating.com/how-to-hook-...ut-rca-cables/ and I have a question.


High level input vs Line out converter.


Is there any quality difference? I'm using factory HU.

No difference if your amps accept high level in. If they don't, you will need some type of loc.

What amp and sub do you have and what vehicle are you putting it in?

Thank you! I have a 2018 Ford Escape SE, non-Sony system. Alpine MRV-M500 and Kicker comp R 12" sub.

That amp accepts high level in so no loc needed.

Make sure to tap the front speaker signals though. I know the f150 platform has bass roll off on the rear and I am assuming something similar in the escape.
