I have an old Rockford Fosgate Punch 75 watt. 2- channel amp. If i
have 4 speakers all of them the same ohms (4 ohms) how can i wire it
so that all four speakers get some decent wattage?

What kind of speakers?

I actually only have 3 speakers right now but the first two are Sony X-
plod 5x7's and the other is an old Kicker 6.5, i plan on filling the
other hole with another 6.5 probably a kicker

I think those were able to handle a 2 ohm load, so you could parallel the
5x7 and the 6.5 on each channel.

No guarantee on the quality of sound you'll get though. If you find one pair
overpowers the other you can experiment with some large, 1-4 ohm fixed
resistors in series to attenuate the louder ones.

I asked a friend of mine and he said that the best way was to simply
take the positive's of two speakers, wire nut them together, and then
run a third wire from that and just use that as the first channel
positive. Then do the same with the negatives of those same two
speakers. Would this be ok to do? Would i affect quality of sound at
all?

Yes, that's what it means to wire them in parallel. You're referring to one
of the 5x7's and one 6.5 in parallel, correct? And then one combination of a
5x7 and a 6.5 will be connected to the left channel, and another to the
right channel.

One speaker may be louder than the other. Best to just try it and see if you
like the sound.

I actually owned a couple of Punch 75s back in the day and they were 2
ohm stereo stable and 4 ohm mono stable. Of course, they were great for
competition due to their gross under rating, even though I never
competed. I remember those multi-speaker systems being run from one 75
(yeah right) watt amp, which was actually pushing close to 400 watts RMS.

goddamn...looks like i really picked up some good stuff then. Any
other ways i could do it? just curious for some diff. ways i could
hook them up.

I would just wire your speakers in parallel to get yourself a 2 ohm
stereo load. Depending on the age/condition of your amp, you should
easily be between 75 and 100 watts RMS per channel. If you are feeling
brave and that the Punch 75 has enough juice for you, you could also run
a sub off of the bridged channel.

In fact, the old school punch series really shined because they could
run tri-mode. For example, you could bridge it to run your subs, and
still run stereo to run your high end, hence the reason that many ran
multi-speakers off of them. I remember one time seeing a dude who had a
single Punch 45 driving 4 12" subs and 4 6.5" coax speakers. Basically,
as long as your mono load stayed at or above 4 ohms, and your stereo
load stayed at or above 2 ohms, you could do just about anything with
those amps.

Fast forward to today, I wouldn't do a multi-speaker application off of
one amp because I have always been a "quality" versus quantity
audiophile. In fact, I replaced my totaled '07 Honda with a '06 Mustang
GT and am currently planning on going with both a 4 channel amp for the
Infinity Kappa 6x8s that I just purchased and getting a single channel
amp for the JL Audio Stealthbox that I am going to throw in there in
2008. I am going to turn the so called Shaker 500 into a real 900 to
1000 watt powerhouse! Sadly, the whole replaced system is not going to
cost much more than the so called Shaker 500 upgrade (good job Ford).

Now, my choices are slightly different from yesteryear. I am
considering going with JL, MTX, or RF Power series amps because I was
less than pleased with the last Punch series amp that I purchased seven
years ago. Let's just say that the Punch 150 that I had from 1990 would
have out performed the Punch 250 that I purchased in 2000 and boy did I
ever regret "upgrading". In fact, I left that amp in the car that I
sold powering 2 Infinity Kappa 6x9s, even though I told the guy I was
going to take it out. The Punch series just isn't what it used to be
but I am still impressed with the Power series!

Of course, those are just my opinions, I am sure someone else will chime
in and say that the current Punch series is OK..... It just isn't for
me anymore because I remember the old school Punch series!

Thats a good idea. But actually, since i have heard that the punch
amps were quite good for high end i was just planning on using that
amp for the four mids in the back shelf. Then using my new Rockford
punch for the 8" woofers in the back (2 of them) (i know, i know, its
not that great, but! i did have a Sony amp before so at least i did a
little better ) and then i plan on running 2 old Rockford soft dome
tweets in the rear panels and then the two front 4" mids off my deck
and Pyramid EQ/AMP.But thanks for letting know i actually did find
some quality stuff

There is technically nothing "wrong" with the new Punch series except I
was told that the new amps made overseas versus being produced
domestically AND the fact that they are not as grossly underrated as
they used to be nor are they even rated the way they used to be.

For example, the Punch 250 was only rated at 62.5 watts per channel @ 4
ohms with a THD of .05% whereas my Punch 150 was rated at 75 watts per
channel into a 4 ohm load with a THD rating of .05%. IIRC, on my Punch
150's born on certificate, it was pushing just over 110 watts per
channel into a stereo 4 ohm load with a THD of .05% and 420 watts into a
4 ohm mono load at 1%. In fact, I had it driving a 12" Kicker Solobaric
woofer, back when they were actually round, in my 1996 Thunderbird and
the Punch 150 drove that power hungry sub pretty good. When compared to
the Punch 250's born on certificate that hardly made much more than its
rated 62.5 watts per channel on its born on certificate, I started
thinking that the new amps were not the same as the ones I grew up with.

Regardless, I had purchased the Punch 250 because it was more efficient,
i.e. no more dead alternators, and initially used it to power a JL Audio
Stealthbox in my 2000 F150 extended cab truck. I then moved that amp to
my car and one of the installers told me I was nuts for using a Punch
250 for driving a pair of Infinity Kappa 6X9s in the rear deck because
it was too much power. Well, for FIVE years I had it pushing my 6x9s
with both myself and my now deceased wife driving that same car, and
both the Punch 250 and the 6x9s were still working when I sold the car
last year.

With all that said, I am still considering the Power series for pushing
a JL Audio Stealthbox that I plan to purchase in a few more months to
put in my 2006 Mustang GT. I am also considering a Power T400-4 to
drive my Infinity Kappa 6x8s that I have yet to install in the car.
