Amp + 6x9 enclosure help

[trancehead]

Im about to strip the back of my car and put buckets + harnesses in..

The rear or the car will be completely stripped and i have bought 6x9 enclosures that im planning to sit on the floor behind the seats with the amp in the middle..

How safe is it to drill into the car on the floor for the boxes and into where the passengers would sit for the amp?

I'm no expert but I know that the fuel filter access panel is under the rear seats, which would suggest the fuel tank isn't far away. You don't want to be drilling holes into that.

i defiantly wouldn't be drilling deep into them if i were due to the previous comment
