Well, I have finally stumbled across a question where I can truly consider myself to be an expert
. Ive been selling and doing car audio installations for almost 10 years. I have competed in stereo competitions and have been invited to two World Finals (just couldnt spend the $1500 to register and for room and board while we were there.)
So, after that. My suggestions are this
.and I just got done doing this in a buddys 67 Mustang (I know) last year. A pair of 6-1/2 components in the front and a pair in the rear. A deck built into the glove box to retain factory looks. A 4 channel amp mounted in the trunk. You can add a small sub amp and a 10 sub to fill in the lows you dont have to rattle the windows if you dont want to- not all subs will do that.
Reasoning. Round speakers will produce better (clearer) sound than oval speakers like 6x9s. Go with the component speakers to separate frequency responsibilities. Component speakers use a separate crossover mounted away from the speakers to send only the highest frequencies to the tweeter and the mid frequencies to the 6-1/2 round woofer. This will help keep everything nice and clean sounding. Adding the four channel amplifier to these four sets of component speakers will make them be much more efficient. Most head units only put out about 15-25 watts rms. Most of the speakers Im going to recommend want about 50-75 watts rms to upwards of 100-125 watts.
Boss, Pyle, Dual STAY AWAY!!
Pioneer Great headunits wont use anything else for a good headunit. Look for one that has three sets of preamp outputs. This will largely let you critique the sound of the system when adding a four channel amp.
Pioneer or Kenwood use either of these for your component speakers go for the pioneer premier series. However, if you can stray from your manufacturers list go for Kicker, Infinity Kappa, or Polk.
Amplifiers From your list, Kenwood is OK. But, again, if you can stray from the list, look for Kicker, Alpine, or Infinity for a 4 channel amp. If you are looking for doing a small 10 sub in the back, go with a Kicker or Alpine 250 400 watt mono amp. You could do a 10 pioneer premier sub from your list with this wattage, or you could look for a Kicker CompVR dual 4 ohm sub.
Youll want to get a four gauge amplifier kit that includes a capacitor or get a separate 1 Farad capacitor this will do two things, help reduce any alternator whine in the audio signal, and also help protect your alternator and battery from any sudden drain.
If you have any questions, let me know! :cheers:
