You guyz really need to get the damn battery into the boot!
A stainless cover for the filter sounds good but staino grabs heat like no tomorrow , a bit of carbon fibre cloth kit made into the same shape will do wonders. Ive got a big roll and a small kit for a bicycle frame repair i keep forgetting to do , too bloody cold n wet to ride is my excuse.....
Love the FOCAL speaker upgrade , man , i have Jm Lab / Focal home speakers and they are absolutely brilliant!
One thing i did with my ill fated V70R build was use double the underfoam/sound matting that was stsd in the car as i had extras , but i also put down sound deadning like dynamat too , the carpet still fitted ok in back.
A bigger battery capacity and or terminals for the power to amp etc may be in order?
Love seeing you lot doing stuffs , im right out of it as i dont have the space and motivation will never happen!
