I recently put an amp and sub in my trunk. I want to know some good ways to secure it. I think that putting a rod through the box to underneath the vehicle, but I'm a little worried about drilling a hole through the bottom of the car. It also might create problems for if I wanted to sell the vehicle without the sub in it. Let me know what you guys have heard of or what you have done.

 

The best thing you can do is have a good alarm for the entire car. Park in a secure place.

There might be hundreds of different ways to mount it down. Ask a stereo install shop for how they've done it. My opinion: mount it from the outside using bolts or screws with a hex head. L angle brackets. Or use the bolts from the spare. Purchase a long nut and a bolt that all match. Use a large washer and attach from inside the box. Will need to be sealed up well. gl

 

Yeah, most people secure sub boxes either with "L" brackets on the outside of the box, or with screws through the floor of the box, installed inside the enclosure (remove speakers, screw down through the bottom of the box from the inside)...

No one is going to care about a few holes in the carpet in the trunk. And if they bitch, knock $30 or $40 off the price of the car so they can go to a junkyard and buy new carpet...

 

Just fastening it to the carpet? I was thinking like going through the entire body of the vehicle to the underside. I don't see fastening it to the carpet being a very good deterrent.

 

Not once did I say fasten it to the carpet.

Read much?

 

Obviously I didn't quite understand your post. When you said screwing into L brackets, did you mean screwing wafer screws through the carpet and into the metal floor? Because later you mentioned that a potential buyer wouldn't care about holes in the carpet, but screwing into the metal floor would quite certainly leave holes in it. If I'm wrong, please let me know what I missed. Thanks.

 

Forget the L brackets. Peel the carpet off the box, screw that down to the floor, and then wrap the box back up.
