help with radio install!

Yep, the harness will provide power to the unit, a remote signal to turn on with the ignition, and speaker wires. Not only am I not impressed with the factory ford speakers and head unit, but the speaker wiring leaves much to be desired. I'd run brand new speaker wire to each speaker you intend on powering off of the head unit. In my first car (1991 Ford Aerostar) I installed an aftermarket head unit and some infinity 6x9s and they sounded OK. When I ran separate speaker wires to power the speakers off of the head unit it made a big difference in sound quality.

For the best sound possible though, nothing beats an aftermarket amplifier. Honestly 50-75 watts RMS to 4 channels is plenty adequate to provide loud, clear, and crisp music out of a set of decent speakers.

I see no reason either to run 6 different speakers. The small 3.5" units will pop and crack with too much bass due to their small size. You're better off with a nice set of components speakers up front and a pair of 6x8's in the rear. The advantage of component speaker sets being they come with a crossover to send the high frequency sounds to the tweeter and the low/mid frequencies to the woofer.

crutchfield will hook you up, but honestly all the music you need is pouring out those tail pipes.

Very very cool, and thanks for the lesson! I love your unique ink!

The door and dash speakers in the 6-speaker setup are wired in parallel. The dash speakers use a base blocker to filter out the lows so that the dash and door speakers can operate on the same channel.

You are better off running new wiring, but if you choose to tie the dash and door speakers in parallel like the stock setup, you'll need bass blockers on the dash speakers.

aka component style setup with crossovers.

Component speaker sets > a pair of 2 way 5.25" and a pair of 3.5" speakers with cheapo bass-blockers. The crossover with the component kits are very well designed, while bass blockers are cheap junk
