I now about dynamat because I talk to a guy at my local audio store and he told me that $200 for the kit and $250 for install, if i want thme to do it. That icludes doors , roof everything inside. He said that what happenes a lot is the roof will flex so for sure I will dynamt it. If I want the trunk it wil probably be $600 for everything installed. I am for srure going to get a new alternator upgrade the wires from the alternator. Probably a 200-225 amp alternator. I will get a red top battery and a yellow top for the setero. I know I wil lneed an isolator, will someone explain to me what that is?From the pic I sent, do you think 4 type Rs will fit in there with a ported box or should I go with 2 15s X? Is the F1 with the money, honestly? If it is I wont mind spending more on it,
