Hi Joe, sorry for the late response, I got quite busy lately and forgot to check the post. Thank you for showing interest in helping me!
1: I drive a 2009 Toyota Corolla.
2: Max dimensions are in inches; H|15 1/4 | D|26 | W|32
3: I'm using an Apocalypse AAB-4900.1D
4: I mostly listen to spanish Reggaeton but when I have friends riding with me it can be any kind of music like english rock or pop. I mainly feel a lack of low end when listening to music. I tested different frequencies with a tone generator app and 45hz was the most powerful frequency in the current box. I thought I would add as much information as possible, sorry if it wasn't needed.
Thank you again for even considering helping me out
