Using velcro to secure amplifier to carpet

[JoeK 10+ year member]

Since im mounting my amplifier to the carpet of my trunk, i thought a better idea than screws would be to glue a velcro pad to the bottom of the amp and stick it to the carpet. I actually use this method for my sub box and it stays put. Considering i dont glue over any vents, should this be a problem?

first you don't have to glue the pad there they make sticky back super heavy duty outdoor velcro but if your doing that rename your thread to being hit in the back of the head with an aluminum brick during an accident, a better idea would be to slide a piece of wood under the carpet and then screw the amps to the wood through the carpet.

Doing that would cause the entire carpet to be off balance, and im limited on space so everything is kinda close to each other

look across the bottom edge of the carpet, just run the wood the entire length you need and only the width you need. my box isn't on the wood so I can pull it and get my spare in case of a flat without moving the amps.

You can use a thin sheet like 1/4" plywood or plexiglass with flathead screws pointing up through holes in the carpet and some RTV holding the sheet to the floor underneath. Attach the amp to the top and secure with nuts. Removeable without damage to the car should you need to.

You have to remember, your box is also much heavier than your amp. That's much of the reason that it stays put. Most boxes usually won't move at all under normal driving without any kind of tiedown, provided it's carpet on carpet. You really need to find a way to secure the amp.

I really like the velcro idea. I don't have a single rip tear hole stain or anything in my entire truck.

yep, velcro works until you actually stop quickly, turn quickly, or accelerate quickly on a hot or cold day. then your amp moves, strains the wire connections, which can fail, arc, destroy equipment and start a fire.

i've seen the aftermath that results from velcro. not pretty.

on a hot day the velcro glue becomes liquid and lets the amp slide across it.

on a cold day the velcro glue becomes too stiff and just lets loose.

use screws to mount equipment. it takes just as much time to do it right as it does to do it incorrectly.

as mentioned, you can use silicone to glue a piece of wood down to metal, then screw through the carpet into the wood. that works fine and silicone is an excellent adhesive while not being totally permanent (can slice with a razor).

if you don't want holes in the car, then you don't want to add to the factory system or you need to remove panels, buy equipment made to be hidden, and stash the amps behind factory panels so they are not visible.

I say do it. Just use the hard side of some thick 3m velco and lay it on the bottom parimeter and if needed a strip in the middle. I think you'd be fine with just 2 thicker strips going the lenght of the amp.. As long as your laying it down I don't foresee any issues.

Is the Scion trunk carpet typical trunk carpet? Is it meshy enough for velco to bite into?

My backseats do not go down no matter how hard i try so i dont have to worry about injury. The way i have it planned it isnt going anywhere, even if the car flips upside down for that matter
