what happens when...
hey i am wondering what will happen if i hook up, 8 Pioneer Premier
TS-A941P speakers to a Power Acoustik OV2-1600 amp... 4 speakers per channel... what will each speaker put out? and does this hurt the speakers or amp? |

A TERRIBLE EXPLOSION WILL OCCUR WITH MUCH LOSS OF LIFE!!!!!!
Actually, you CANNOT do what you are describing as that amp is only 2 ohm stable per channel. Were you to connect four of those speakers to each channel that would present a one ohm load, which would fry your amp (or more likely immidiately put into protection-mode and shut it down). You can connect two of those speakers per channel however, for a total of four speakers. My guess is that would still be quite a bit of sound. MOSFET |

what is the impedence of the speakers, and what are the ratings on the amp? -- KU40 |

what is the impedence of the speakers, and what are the ratings on the
amp? Look it up. I did to answer this guy's question. MOSFET |

that actually helps alot... how do i figure out how many ohms a bunch
of speakers represents? MOSFET wrote: what is the impedence of the speakers, and what are the ratings on the amp? Look it up. I did to answer this guy's question. MOSFET |

well i guess you're better than me then. I suppose I just think it's good for a guy to find out a little about his equipment for himself. -- KU40 |

But you forgot the series-parallel rule. The OP can do it.
4X4ohm drivers in Series paralell=4 ohms Do that per channel and the amp will work easy.... Each speaker will see 77.5W which is 2.5W shy of it's rated power.

And after you learn all the below.... here's a good calculator!
http://colomar.com/Shavano/impedance_proc.php Brandonb - sorry, had to. I. Care wrote: Speakers can be wired in series and/or parallel combinations I believe. Not sure how well series/parallel combinations perform volume wise but their load on the amp is predictable. Speakers in series using simple resistance are added together R(t) = R(1) + R(2) + R(3) + etc. So for series connections 8ohm + 8ohm = R(t) = 16ohm - (Spkr#1) + to - (Spkr#2) + | | | | neg Sig pos Speakers/resistances in parallel 1/R(t)= 1/R(1)+ 1/R(2) or 1 ---------------- = R(t) 1/R(1) + 1/R(2) So two 8ohm spkrs in parallel 1 --------------- = R(t) = 4ohm 1/8ohm + 1/8ohm - (Spkr#1) + | | - (Spkr#2) + | | | | neg sig pos So 2 8ohm series speakers = 16ohm but when placed in parallel with 2 more 8ohm speakers is: 1 ------------------------- = 3.2ohm 1/16ohm + 1/8ohm + 1/8ohm Hope that doesn't confuse you too much, and that my simple graphics are readable..... |

and that little rule... if i come up with a system that come out to 4
ohms, does that apply to one channel or the whole amp? for example, can i design a system that has mult speakers that come out to 4 ohms on channel 1, and then another system that come out to four ohms on channel 2?

that actually halped me a lot.... now one final question and i will
leave you all alone haha... lets take that example again (4 speakers wired up per channel (lets say 8 speakers on the amp total) what is the wattage they will each pump out?.... after that question is answered i think you should all get paid per hour cause you people are great... -Mike I.

SNIP That is the load per amp output/channel. Your amp is 4ohm per channel stable. So if you are going to run 2 channels (stereo) you want your combined speaker impedance to be 4ohms per channel. As Chad said since your speakers are 4ohm you need to wire 2 sets of 2 speakers in series, then put those 2 sets in parallel with each other. Wire speaker #1 pos to speaker #2 neg, speaker #3 pos to speaker #4 neg, this gives you 2 sets of series speakers, then connect speaker #1 neg to speaker #3 neg and speaker #2 pos to speaker #4 pos, this gives you each set of 2 connected in parallel. That gives you 4 speakers used each channel with an impedance of 4ohms each channel. Then connect the amp to the neg and pos ends of the 4 speaker set for each channel output. - spkr#1 + to - spkr#2 + - spkr#3 + to - spkr#4 + neg signal pos A couple of the references provided in earlier posts shows diagrams of this type configuration I think. -- I.

No, I live on Camano Island, near Whidbey.

To the OP, you should also check out our FAQ (this is my stock advice to many a poster) at: http://www.mobileaudio.com/rac-faq/ Good Luck, MOSFET SNIP I also have 30+ years electronics experience, but I forgot most of it. You at Whidbey? I worked my last 15yrs as an electronics supervisor at PSNS. -- I. Care Address fake until the SPAM goes away ;-} |
