* Factory system (if equipped): Most likely, a factory amplifier (if one was included) would be located under the passenger side of the dashboard, possibly tucked away behind some trim panels. It's often a small, relatively low-profile unit. However, some models might have had it in other locations, so checking the wiring diagrams is vital.
* Aftermarket amplifier: If it's an aftermarket amp, it could be virtually anywhere. Common places include: under the seats, in the trunk or cargo area, behind the rear side panels, or even hidden in other areas.
To find it (assuming it's a factory amp):
1. Consult your owner's manual: This is the best place to start. While it might not explicitly show the amplifier location, it may have diagrams of the audio system components.
2. Check the wiring: If you can trace the speaker wires, they will likely lead you to the amplifier. Use caution when working with car wiring. Disconnect the battery's negative terminal before starting any work.
3. Visual inspection: Carefully examine the areas mentioned above, removing trim panels as needed. Be gentle to avoid breaking any clips or fasteners.
Without knowing if your Tahoe had a factory amplifier or if it has an aftermarket one installed, a precise location can't be given.
