Hi, i have a Mitsubishi Pajero (also known as Montero and shogun) and currently have 2 speakers in the dash and 2 at the rear...when the bass is turned up (on the stock cassette player cum radio) the bass comes from the back speakers...i want to upgrade from the stock speakers and am planning to get 2 speakers in the front and a sub at the back with 4 ch amp...can anyone suggest good type of speakers to use in front? i have seen 2,3,4 and 5 way speakers from various brands...what differentiates a 5 way from a 4 or 3 way..does it matter if i plan on getting a subwoofer...any help will be greatly appreciated
