Not much to write very simple the rears. Just 5 t25 screws again Also one under the little cover in the door handle. Spacers came up a treat but do get very close to the edge of the door trim Just for you barnz my half arsed sparky work. Also when im unsure I just use fark loads of tape. Pic before tape. But once its all in and up and running yes you do have to turn in up about +2 volume to equal the previous volume level but where the old speakers feel over at 22 with a cd I can go up to 30 with a cd only thing is the sh*t factory sub can not keep up at all so ill be changing that on the weekend. Just need to find a decent one that fits the standard shelf. $109 a pair and $13 for MDF so $231 its not bad at all. Another $200 for a sub and some dynomat stuff (if that's what its called) and ill be happy. Time to go and get Britneys greatest hits. Or do what steve said and crank some FAT RICH KARNTS[emoji482]
