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? |

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. Chris wrote in message ...

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? |

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. Chris |

Chris 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. |

Any other ways i could do it? just curious for some diff. ways i could hook them up. |

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 |
