I am going to try putting a 8 inch sub under the passenger side rear compartment because my amp and capacitor is on the driver side. Anyone do this?

 

I'm not sure if there's enough room over on that side, but you can try - it looks like a tight fit and probably depends on the brand/style of sub you're installing.
why not just move the amp to the other side and install sub on driver's side?

 

My amp is so big it won't fit on that side or under the seats without sticking out. The pics I posted is of my truck it fits I just don't know if I can seal it off enough to sound ok.

 

What kind of sub are you using, what are the specs on the sub??

 

It didn't come with any specs. I know its a 800 watt, 8 inch Pyle. I looked online and couldn't find anything either.

 

This is my driver side compartment and head unit.

 

Update. I am trying to fill all the big stuff with spray foam and small holes with silicone.
