4 door accord. Wallin it off. I got the box in and played it and it sounds horrible. Not loud at all. I really dont know what is wrong with it. There are some leaks around some of the edges that I still have to get but will leaks make THAT big a difference? I'm talkin its prolly a about a 138 db or so. When before it was about a 150 in the trunk.pretty tall box... back of suv?
I did a 146.3 with my old hifonics amp. I'm doin about about a 150 with my new amp.146.3 is a huge difference than 150...
but either way 2 15"s walled off should be pretty loud... might just have to go back to good ole woofer back, port back in the trunk
