I'm putting 6x9 in the front door cards now and maybe some tweets but I uses to have those tens under the seats which was quite novel I might say had many people with numb bums haha but the bass is really good concidering their under powerd ATM (bad amp) the hardest part is rattles and vibrations ATM as they give serious flex haha when I get a new and and an ossilator Meter and tune the correctly I'll let you know but I'll record a sound and flex test later xx
Yeah that would be interesting please have you thought about reinforcing the back of the card with a good few layers of fibre glass? Might even be worth putting some sound deddining (not sure that's how you spell it ) behind it or some expanding foam in the actual frame to stop echoing or a bit of vibration if you haven't all ready xx
Expanding foamed the inner carcus so between outer panel and doorcard and the whole quarter panel is fiberglassed that's how I got it flush from the arm rest bit and I've got foam padding on the inside of the rear outside quarter panels what i need to do now secure the speaker cards to the body that's the rattle haha the plastic and metal clips can't hold it they keep squeaking and unclipping ... Move to pm ? As its really gone off topic haha xx
