alright, i have a 95 thunderbird that im tryin to make kinda nice before i leave for the army. i got almost all my stuff for my system just need a few suggestions. so heres the list of equipment

Blaupunkt Sanfransico CD72

Blaupunkt 6X8s in the doors
Kicker 6 1/2 componet set in the rear
4 15" kicker comp CRVs.
directed 500X4 for componets
power acoustik 3000X1

im in the process of getting a MA Audio amp for the subs.

i was wondering what size amp wire i should be useing. im currently useing 4gauge, and considered moving up to 0. i thought about putting a set of 6X9s in the back with set of 6 1/2s in the kick panel, but i dont want it to get too sloppy. any suggestions?

0 gauge back to a distribution block and 4 gauge out to the amps. And use 4 guage ground for each amp.

By the way which MA Audio amp you going to?

shouldnt all the amps use the same ground though?  im useing the MA Audio HK401SX  it breaks down to .5 ohms so i think that'll be fine. claims it can push 1800 RMS at .5.  yea?

You could run a 0 guage ground to a distribution and 4 guage to each amp. That way the amps are grounded the same.

Definitely put 6.5s in the kick panels. It will be a vast improvement over 6x8s in the doors.
Spend as much as you can on those main front components. I wouldn't replace your speakers in the rear - it would be a waste of money in my opinion.

Also just to let you know. MA Audio rates those amps at 14.4volts

14.4 is the nominal charging voltage for a lead acid battery, and is the nominal output voltage for an alternator with the engine running. This equates to a cheap power supply in the amplifier in my opinion, because it is not a regulated power supply - it needs higher input voltage to get proper power out. (A regulated power supply will always provide the same power, regardless of the input voltage...) That or the manufacturer is embarrassed to tell you what the amp makes at a real world voltage, and they want to inflate the abilities of the amp... bad mojo, man! If your alternator cannot maintain 14.4 volts, then you ARE NOT going to get all of the power you thought you paid for.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
