4 4ohm speakers on a 2 channel amp? Parallel or Series?

[Ranger44]

I'm wanting to add this amp I have to ALL 4 of my speakers in my truck. I would like to wire them the best possible way with what I have. I'd appreciate and help from audio geniuses. Please.....

I have 2 of these:

Pioneer 6" x 9" Three-way Speakers, TS-A6973R

* Shallow-mount basket design
* Woofer: carbon graphite IMPP interlaced with Aramid/basalt fiber
* Surround: rubber-coated cloth
* Voice coil bobbin: Glass-Imide
* Copper voice coil wire
* 5/8" PET film-dome tweeter
* 1" soft-dome midrange driver
* 92 db sensitivity
* 4-ohm rating
* 31Hz to 29kHz frequency response

and 2 of these:

Pioneer 6" x 8" 3-way Speakers

Technical Information

# Output Power50W (RMS) / 240W (PMPO)

# Driver Type1.62" Neodymium Neodymium Midrange
# 0.37" Tweeter

# Frequency Response30Hz to 28kHz

# Impedance4 Ohm

Physical Characteristics

# Dimensions6" Height x 8" Width x 2.5" Depth - Mounting Depth

This amp:

Dual XPA2500 300 Watt Amplifier

* 50 Watts RMS x 2 channels @ 4 ohms
* Signal to noise ratio 72dBA
* Variable high pass corssover and variable low pass crossover
* Selectable crossover high pass low pass full range
* Variable bass boost

My head unit is a Pioneer also, it's older, but new enough for the Ipod adapter. I bought it back in 06', and was the highest grade at wally world.

Btw, it's mostly rock/classic rock based music I crank. I'd appreciate any advice.....Thanks!

so the 6x9s are 40w rms, the 6x8s are 50w rms, and the amp is 50w rms per channel. i assume your mounting the 6x8s in the back and the 6x9s in the door, so id run them in parallel to keep them at 4 ohms. youd be sharing the power between both speakers so you would get 25w rms per speaker, which is probably only a few rms over what your hu puts out. now if you wanted to run the rear speakers off from the hu and run the 6x8s from the amp then you could give them the 50w rms power they need.

your putting out 75wrms at 2ohms X2......now wiring any two speakers in parallel will give you a 2ohms load...... so wire them in parallel......which two you wire together, will give you L-TO-R orrrrr F-to-B... that my fiend is up to you.


there will be no difference in performance for F2b Or R2l wiring.... just sound controll.

Not entirely true. If you care about a realistic soundstage at all, you should only wire the 2 left speakers together, and the 2 right speakers together. I for one would definitely tell the difference and it would bother the crap out of me.

Now, if a good soundstage doesn't mean anything to you, then it makes no difference.

I agree..I did left to left and right to right!

no it is very true.

i was referring to an rms load when i was talking about performance. L2R gives him a 90wrms per channel. and F2b gives him one channel of 80 and another of 100. but it doesnt matter. no mater what hes still getting 37.5 watts per channel. so i say again

there will be no difference in performance for F2b Or R2l wiring.... just sound controll.

(sound control) IE helping you create your sound stage. which i agree 1000% very important to have. but one of the possible tangents i decided to not talk about and over load you with info. i merely gave you the info you asked for. cheers

 

[Ranger44]

Thanks everyone!

I'll probably just wire one channel to the left and the other to the right. And in parallel.

I appreciate the opinions.

oops, i guess i should have checked the specs on the amp while i was checking specs on the 6x9s to verify that all the info the OP provided was correct before trying to help, thats why im glad we got you here, youre an audio god!

lol thanks for the complement. but i wouldnt go that far. i have my bad days just like everyone else. just here to help.

id run the 6x9s off the amp they would probally give you a little more bass and run the others off the headunit.
