Pioneer Head unit, old school ppi 450 running 4 jl vr 6.5 component sets. Front just put the tweets in the door about where the window crank would go, and in the back seat i removed the ash trays made a plate covered with some fabric and inserted the tweeters in there and made another adapter plate to go from the 5x7 to a 6.5. mounted the amp on the back pass. side compartment. I will soon be putting in another amp and some subs along with a 5 farad capacitor. I have always found ford alternators to be pretty powerful but it never hurts to Upgraydd (2 d's for a double dose of his pimpin) to a higher amperage alternator if you are going to be running more than one amp.
