Quick question, ive got a 175wx2 amp. ive got one of those channels wired up to my subs. I want to take the other channel and wire it to my rear speakers. this way i can see how much i like power speakers and possibly use this setup until i get another amp. the speakers are pyle pl-6984, they're the 6x9 4-ways. smething like a 130 watts RMS. yes i know im being pretty vague about the amp but i bought it second hand.

aaaaanyway long story short i just want to know if i should wire them in series or parallel to my amp. thanks in advance to those who reply.

 

you were also vague about the speakers. The question is how many ohms do you want to run. If you run paralell, you 1/2 the ohms, if you run series, you double the ohms. Higher ohms = more bounce to the ounce. Lower ohms = better sound quality.

 

You have a two channel amp and you wanna run the subs off one side and rear speakers off the other, Thats really not a good way of going about it and it will sound like crap in my opinion, a two channel amp is meant for a stereo( left and right channels) set of speakers, either a set of subs or bridged to a single sub or a set of L&R speakers, the way you want to do it you will be running a mono set of subs and a mono set of rear speakers and you will be losing a total left or right channel in turn losing alot of sound from the missing channel, plus if you run it that way you really won't be able to use a crossover to send the lows to the sub and the highs to the rear speakers. I say you should just wait till you get another amp or sell the the one you have and get a decent four channel amp.

 

^^ you can keep the channels by using a Y on the RCA inputs to the amp. If it's a monoblock amp, it won't matter either way.

 

theyre 4 ohm speakers, so theres no way to just send the 175 watts to them? i suppose id like to double the wattage then, so 8 ohms would mean series? maybe i will just wait until i get the other amp. ill also be getting front speakers dlivered in the next day or so so maybe ill just wire the left and right up in series then.

 

Kinda ironic that 20 minutes after i read this post i stumble across this at work. I know its not for car speakers specifically but it is for home theater installs. Might clear up the whole parallel versus series this that DTN was talking about.

Also in my head I would think wiring something in parallel would keep the same amount of power going to the speaker versus series in which there could be a voltage drop, which would in turn affect the power to the second one? Am I right or just losing my mind?

 

actualy, the whole series paralell thing... for series, your ohm value will be R1+R2+R3+R4. for paralell your resistance value will be 1/(1/R1+1/R2+1/R3+1/R4). but if the resistance in paralell are the same, it becomes x1/2, in series it becomes x2

That is just the cold hard tech math. There's alot of other factors that go into calculations for speakers as well, but because it would require us looking at inductance values, volts, amps, time periods, wave forms, and other things it is easier to just use ohms. If you did all of that it would tell you how it would sound by measuring wave distortion.
