Thanks for the reply VP.
The Vibe amp is a class D amp, it don't have a fan on the top so may not be the one you are thinking of.
I have been thinking about doing a fibreglass side enclosure rather than the IB sub but I've heard a lot about not getting the sub's sound into the cabin.
Is it better to hack the Rca rather than use a LOC?
Am I right in saying that a good quality sub in the boot will pick up on the lower frequencies that the underseat woofers won't and work to compliment each other.
Sorry for all the questions, I just don't wanna throw any money into the wrong products.
