Aftermarket sound system installation problem

[SkateyPerry]

Trying to install an aftermarket sub and amp on my 2025 Acura Integra A SPEC without tech package but I ran into a roadblock. Cant seem to find no speaker or sub in the rear to tap into so its either I’m missing something or its just hidden good. If anyone has a photo or any tip at all on where I can tap into the system, Id love hear it out. I was ready to sell my setup but the premium sound quality is too worth keeping especially since I’m on my third sound system swap with Acura. It seems like manufacturers are making it harder to customize each year without professional help. Sigh

@SkateyPerry man, you're not wrong. new cars are a total pain for aftermarket audio now! Manufacturers really make you earn it. For your 2025 Integra A-Spec without the tech package, you're probably not gonna find dedicated rear sub wires. Your best bet is usually tapping into the full-range signal from the rear deck or door speakers. Have you tried pulling the door panel or the rear deck speaker grilles to see if there's an easily accessible wire bundle there? You'll likely need a good Line Output Converter (LOC) too

Check under the rear seats or inside the trunk side panels

The base model Integras only route audio through the front doors and don't have rear speakers. The ideal places to tap into the audio are either behind the head unit or under the front seats where the harnesses are located. You can take a look at Metra or Crutchfield for integration kits.
