im wanting to insulate my trunk lid, considering i have amps in tehre that get ridiculously hot (the trunk inside is burning hot), any suggestions on what kind? no fiberglass itchy stuff tho. i know Second Skin sells some just for that, but its super pricy

 

Dynomat?

 

i mean heat insulation, not dampener

 

this is a crazy idea but...

put a cooling fan where the stock sub was and have it blow hot air from the trunk into the cabin through the rear deck. maybe wire it through the amp so it turns on when the amp does?

just a thought...

 

try `Reflectex` inside the trunk lid- made for heat reflection- see internet for details- sold in hardware stores,,pretty cheap

dynamat would probably help too--its foil faced right?

I like the idea of a 12volt fan pulling heat from the trunk!
finally that small pass thru opening has a real purpose!

 

If you insulate it the heat in there will be even worse- kills electronics. 12v fan on amps sounds like a good idea.

 

wouldnt putting reflectex on the inner section of truck lid keep heat from pentrating thru so much

I have it on my inner roof of the house and the temp coming thru is down 30 degrees

 

Hadn't thought of that- with insulation maybe cooler during day & hotter at night-

 

I will figure out how to remove the cover on my car and try reflectex,
its used on several other projects around the house, and for the car windows when parked

 

Id bet the majority of the heat in there is coming from the electronics insulating it will most likely only make it worse

 

i live in texas^^ i will come outside after my cars been sitting in the sun, and open my trunk and my amp will burn my hands

 

Unless its been running prior to it i fail to see how it could get that hot as its in indirect heat and not direct. We see 100 deg summer temps (and i have visited texas and florida many times and and my amps have never gotten that warm from sitting in the trunk without them being on.
You also have to remember that the trunk is vented. When the car is moving air is being pulled thru it and out vent spots so it will draw out the warmer air.

 

^ hmm ive never noticed these vent spots in the trunk. where are they?

 

my trunk gets extremely hot from the sun hitting a dark grey car

No amp or anything-no inner heat source
open it at the grocery store and a heat wave blast forth

I take insulated grocery just bags to get the ice cream bars home safe!

 

who has experience removing the trunk lid cover - just pop out pegs or???

 

^^^ Gotta protect the ice cream bars A note on sucking the hot air into the cabin.. this would suck in the summer time?? Or am I missing something

 

Im not saying it doesnt get hot. The inside of the car gets hotter imo. If his amps are getting hot enough sitting in the trunk off that it feels like it would burn your hand

 

but i have ac in the cabin, so after ten min or driving, it would be blowing in cooler air
