First of I know Ive been blowing up this place lately but I have so many ?s

5 Channel Amp Kenwood X5-5s Specs:

80 W x 4 / 350W x 1, (4Ω) (20 Hz - 20 kHz, 1.0% THD) (20 Hz - 200 Hz, 1.0% THD)

and or

80 W x 4 / 350W x 1,(2Ω) (1 kHz, 1.0% THD) (100 Hz, 1.0% THD)

So from my understanding this amp can take either 2 or 4 ohms but with different sound frequency outputs?? I dunno

I have 4 RCAs to use with my PAC ADD GM 24 harness custom made from advice on here.
Channel 1: Front Left Component @ 4Ω, using RCA1
Channel 2: Front Right Component @ 4Ω, using RCA2

Channel 5; Subwoofer @ 4Ω, using RCA3 (from either rear speaker)

Pretty strait forward so far right? My question is, I want to try to use both rear speakers. If I dont like it Ill ditch em and go with the configuration above. I do want to try just to compare the sound difference if at all possible

Rear speakers are 4Ω about 25-35 watts RMS I believe

Should I....
A. Series wire both speakers creating a 8Ω load
B. Parallel wire both speakers creating a 2Ω load (my concern with this is my amps rating at 2Ω, if im reading the specs above correctly it looks like the sound output will not be as good?? Am I reading the specs right??)
C. Use an RCA splitter off of my 1 remaining RCA cable split it into 2 and plug those into Channels 3 and 4 on my amp, where I would be now using all 5 channels. What would this do?
D. Just use 1 rear speaker on Channel 3 or 4?
E. You are crazy Rob and this audio stuff is making you crazy. None of these will safely work.

I hope I explained this well and Im making sense. Whew!

 

Always wanting to learn more.

 

I'll go so far as to say you're over-thinking it a bit....

A & B) I would never wire up front & rears together, you're going to kill the performance of the amp and also any ability to balance the sound in the cabin with fade. Performance specs will always change as the power output changes so you're not reading the specs wrong. Whether sub or mains matching your speakers to the amp specs is always important!

C/D/E) I would RCA split the rear RCA's for your sub channel, thus creating 2 pairs of rear, rather than just using a single rear channel.

I don't know that amp but I'd look through the docs, sometimes amps will have internal crossovers that will pass the low cut off to the channel without you having to wire up RCA's. Also amps sometimes have OUTPUTS post-crossover that you could then feed back into the sub input. Again those options are all over the place by make & model so check your docs!

And when in doubt, keep it simple....

 

Ok cool, So Ill just wire in 5 RCAs splitting one rear into two, the other rear going to the sub.

Thanks Man!!

 

Couple of things to keep in mind with this:

1) Every time you fiddle with the fader you'll be changing the bass level. So be REALLY sure about those rear speakers you intend to use!

2) By using only 1 side you will not be getting all of the low frequency signals. I'm not sure how important that is to you and will vary based on what you listen to...

 

I would suggest buying 2 Y adapters and using the FRONT signals for both the front and sub inputs (XR5S has 6 RCA inputs, use them all). I would split fronts to the sub simply because that's what you'll be adjusting the volume to, so the sub would be proportional regardless of where you put the front/rear fade.

Run the rear RCA's only to the rear inputs.

That way each speaker has it's own amp channel and the sub gets two inputs

 

100% how I would and have done this in past

 

This sounds awesome, I think im going this route.

Thanks

 

Perfect! The obvious was staring me in the face, must have not had enough coffee.
