Hi guys, i need some advice before i do anything. i'm thinking about to cut a big hole like the red rectangle lines in my reardeck of my car as shown in the pictures below making it look like an Semi Hatchback, i want to know if i should do it, or not? what will be de pros and cons of doing it? will it help a lot with the bass or not? curently i already have cut 4 holes, 3 big and 1 small as you can see in the pictures and it did help a lot. so what you guys think about it? thanks.
