I have a JL Slash 500/1. It is about 13x9x2.5 inches. I am getting a fiberglass side enclosure made and I want to sub to avoid being on the back of a seat or stuck on the opposite side panel. I know a lot of people mount their amps under the rear shelf. That is where I want to check first but I have to figure out if it can be worked in around the factory sub. Second option is under front seat but just trying to take a peek there seems to be a ton of stuff.

Someone said just slap it on a board and throw it next to the spare tire. I wasn’t sure about that.

Is there space pace next to the ML sub to put the new one?

It is going to be the JL amp and a AudioControl LC2i loc that needs mounting. Any suggestions?
