So basically I have this sitting in my boot, I do have an amplifier hooked up its a Vibe A1 amplifier however due to me having two subwoofers and the amplifier not being that big (800w) its not pumping out as much bass as I would like.

I have got some vibe 6x9's wired up to my amplifier but I'm debating whether to get rid of them and just upgrade the front and rear speakers again, along with a better amp?

However would it be better for me to get rid of one of the subwoofers and do a simple boot build e.g false floor and a housing unit for my amplifier?

Any help would be appreciated as I'm not an expert on all this audio
