I'm planning on drilling through the metal floor of my 99 TJ just beneath the rear passenger seat (to secure an amplifier). Am I gonna hit anything down there or should I just drill away?
Once you drill into the gas tank, make sure you grind all the burrs off and make lots of sparks.:flamethro Seriously though, there is a lot of useful stuff under there like brakes lines and the gas tank. You might remove the tank and make the job a lot safer.
I mounted one under the rear seat (above the gas tank) a long time ago and like 3 Jeeps ago. Make sure you know whats down there and be careful not to penetrate through the hole and into something else after it is made. It's a good idea to use plumbers putty or something simular to keep out moisture when you tap the screws. Just my 10 cents.
Soon my new project will have an amp to i thought glove box center councel or under the seat, you need to think dry and hidden from thieves for when the top is off everybody seems to think under the seat is the best option.
My amp is hidden under my backseat and the place i had it installed at put some kind of clear caulk underneath to seal it off from water. Seems to keep the heat down well enough under there. Better than a closed trunk i'd think(especially with my top off). What speakers you plan on putting in? i'm running 2 4x6 2way and 2 6x9 4way pioneer, 2 memphis 10's, memphis pr500 amp, and a sony gt-400 head

Listen to everyone else and just look under the spot you plan to drill. It would be very difficult for us to give you an exact measurement of the location of every component under there.
