for the small one now your probably fine with that ground...when your talking 2 2500 watt amps...that ground is questionable
it may work, but in the long run, your amps will run hot and could possibly damage them over time. plus, not get the output you expect.

A tip that always helps me is to look for spot welds. That means there is another sheet of metal right behind it. Dont screw directly into a spot weld, just next to it. The screw will hold MUCH better than if you were to use a location with only one sheet of metal. Grind away the paint and use a star washer as mentioned above. I find that using a large self tapping screw (or a regular screw, but you have to pre-drill a hole) with a hex head works best. Something with deep teeth that can grab more metal. They have somethign called a 'thread-forming' screw that looks a bit triangular from the end, it presses threads into the sheet metal instead of cutting them which gives you a stronger hold.
