Likely fuses to check for no sound from aftermarket stereo?

[KMeloney]

Hey all,

Had to replace my battery and BCM, and now my aftermarket stereo is not playing (the amp and crossover are not powering, and so there's no sound anywhere but through the factory center channel in the dash). I'd imagine it's a fuse issue, but I'm not sure where to check.

1. Am I checking the fuse box just inside of the driver's side door, or am I checking the under-the-hood fuse box?

2. Which fuse slot should I likely check? (Which fuses slots are typically used for stereo installations?)

Anything else I should check? Does this sound like something other that fuse-related?

No, I didn't check to see if there's an on-off switch on my amp... I don't believe there is, but it's been a while since I dealt with a stereo power issue. Anyway, every nav/stereo/blinker/etc. sound runs through the amp, and so I need to figure out why it currently doesn't have power.

Thanks!

If it's an aftermarket amp then I'd look under the hood. I'd look for a heavy gauge wire running to the battery that doesn't look factory. It should have an inline fuse holder and inside of that should be a blown fuse keeping the amp from coming on.

Thanks for the reply!

Will the fuse be at the battery-end of the wire, or elsewhere?

It should be within 18" of your battery.

Thanks. It appears that I have a relay with a reset button at the battery -- but the reset button isn't resetting anything.

So... I have an appointment to have it checked out. I'll report back on the findings in hopes of helping someone else.

Ok, so it was, in fact, the relay by the battery that needed to be reset. Problem was that it was installed tight behind the battery, and so when I thought I was pushing in a red reset button (and that it didn't resolve the issue), I really needed to be throwing a switch that I couldn't see.

Between the engine bay bracing and the battery proximity to the relay, it's tough to get your hand in there if you don't know exactly what you're looking for.

Thanks for the input, folks.
