done!!!!
took it all out and broke it up with a hammer and chisel to be safe instead of just smashing it, all it had inside was some relays(I think) and some wires, sub+amp wire was in there pointlessly and was only wiring for lights thank god. ive now re wired the lights and for now there just taped to my battery until I find a way to get them tucked away somewhere, I also rewired up my door card speakers as the wire had snapped..
took pics of what I was doing
breaking the 'box'

box broken

rewired

works better than before I'd say, lights seem a lot brighter
