i'm not going to compete, i'm just doing this so that my install looks nicer, more secure (mdf slides around

) and it also needs to be easy to remove, hence the brackets.
essentially this is just going to be a SQ setup, its not necessary for me to do all this, but as i have access to the materials and tools to make it i thought i might aswell.
and my car will never see a competition, i'm not really that driven towards them. i moreso just want to be able to have a nice sound setup when i'm driving, and knowing its secure back there.
