I have been reading through the posts and I was wondering if anybody has put in 8 or 9 after-market speakers with two amps--something like an alpine 4x40 and maybe a 5x40? I assume the dash and rear overhead factory locations house 3.5"? What can I fit in the factory sub location? Right now I have 4 speakers and an infinity bass link but it would be fun listening to Marley with between 8 or 10 speakers. Don't get me wrong I don't need to top the neighbor kid--I just enjoy a rich full sound......
