Hello,

Im going to be mounting my subwoofer box down to that small ledge/shelf in the trunk of my 01 GS300. Im going to be using small l brackets from the box to the floor board portion so the sub fires upwards through the factory sub location. My question is, Im pretty sure the gas tank is underneath of that ledge, but how far under, and can I safely drill my box into that surface without causing problems.

Thanks in advance
