Is there a decent place to ground an amplifier under the driver seat ?

2019 big horn. Base non amplified system. Looking for a good ground for an aftermarket amp under the driver seat.

if you lift up the seat rail mount you can get a large connector under it. I removed the factory sub in the alpine system and use the pre-existing bolts to ground my amp. Willing to bet you have the same bolt hole locations behind the rear passenger seat where the sub would go

Agreed - use the seat bolt (just make sure there is no paint between your connector and the rail.
