Drilling under the driver seat...

So, I'm prepping to do a dual band commercial radio in my 98 ZJ grand cherokee. I've decided to install the radio under the driver's seat since there is plenty of room and it's a nice location to feed the antenna and power wires to.

My question is this... can i drill the radio mount bracket into the floor panel? Is there anything under there I should be worries about and how do I check to make sure the area I'm mounting the screw to wont be hitting anything important? I could probably get away with a single screw but I'd prefer two for a more secure mount.

thanks for the help... I'm new to Jeeps and love reading these forums

I would just make sure you seal it, and make sure you aren't drilling in to your exhaust. You should be fine. You can see where your seats bolt in to the floor of the car from the underside. Measure where you want the mount in distance from the seat bolts and then drill from the underside if you really want peace of mind.

All the time I've invested in fixing holes in floors, and you're gonna add your own?

I'm just kidding. Just make sure you use lots of undercoating or something to keep the screw holes from rusting out the rest of the floor.

IMS there are brake and fuel lines running along the inside of the "frame rail" on the drivers side. Probably not good to hit those. I think the parking brake cable may run through there too but it's been awhile since I was looking up at that area. Nothing important bolts to the underside of that sheet metal though. As others have pointed out, make sure to seal your fasteners. Maybe use bolts with rubber washers and RTV.

I agree with everyone that's posted and would repeat that I would definitely drill from the underside "up" to ensure you don't hit something you don't intend to.

Thanks for all the feedback, everyone. I'm gonna try to find an alternative to drilling because it would suck to have a rusting issue. Though if I do end of drilling I think with a rubber grommet and some undercoat it should be okay.

If you're going to take the seat out to do it, consider making a plate with holes to match the seat bolts. Then use the plate to hold mounting studs for your equipment. Not sure it's feasible, just a drawing board idea.
