i know this is a fairly popular head here so i hope someone might know.

it has 3 sets of rca's on it, one set being left and right sub outs, i really need one mono sub out for electrical reasons and also to make the physical wiring of the system easier. it dosen't say in the instructions that using one or the other alone will give a mono signal and i don't want to find out the hard way that i can't use a 2 to 1 rca adapter on them.

if anyone happens to know i'd appreciate finding out. thanks.

start where you are,
use what you have,

Using one or the other will only give you half of the stereo.. i.e. right or left channel..
If you combine the two with a 2 into 1 adapter, you will in essence have a mono signal..if you were to hook up a single speaker, the total signal will be coming thru the one speaker, aka mono.

I have that unit. You can put a Y on any output and will get what you want. If you use the sub output then off course it will be a low freq filtered signal output. Why you need a single RCA input? Most mono amps has R/L inputs anyway with a single speaker output if that's what you need.

thanks kyote, i know generally how it should work but i was looking for specifics as to this head. in the install instructions it actually says you can just hook up one rear side for a mono sub, but it is for when you are using the internal amp. i guess i was hoping the same was true for the rca's but somehow got ommited from the instructions.

alex, having a single out would be part of the ease of physically wiring it that i mentioned. the amp is in the trunk and i am running leads through the front trunk wall. i'm using some female to female wall plugs to do it and running one less would make it that much easier.

i really don't have to run any sub leads, but since this head has sound processing (the x-over specifically) built in, i want to try and use it instead of the amp x-over (4ch for left-right and bridged sub). it's a choice of extra wiring for hopefully better (assuming the heads x-over is better than the amps) and simpler system control or simpler wiring and splitting control more bettween amp and head.

I know what you are talking. The Y will save you one wire.

I am a little confused. Let me see if I have this straight
1) Red, White
2) Red, White
3) Red, White

Red=Right, White=Left

Assuming this is correct. The 1=Front, 2=Rear, 3=Sub. I have never seen an amplifier that only accepts 1 RCA input either red or white. If you wish to run only one sub. Then you either
A) Run 1 channel to the sub.
B) Bridge 2 channels to the sub.

Doing either of these has no affect on the RCA cable what-so-ever. If you are trying to hook up an amplifier and need some help
email
me and I can give you my number and walk you through or email you some help.

Hope this helps

actually mach you're confusing me .
seriously, i've put in a few systems and understand what you mean, but this dosen't have to do with the amp as much as the head. hopefully if alex is right, i can combine them to go through the trunk wall with just one lead like i want. i can branch back to two if i need to once i get through (actually just looked at the manual to see that i do, but i have had amps that would take one input if it was going to be bridged).

i just didn't want to try one lead or the other only to find it wouldn't work that way or try ganging them without knowing if it would short the head.

Let me see if I can clear this up.
1st
Correct unit?
2nd Then you locate the sub output. It will have 2 RCA wires. 1 wire is white (left), the other is red(right).
You run the RCA cables to the amp. The amp takes both cables regardless of whether it is a mono or multi-channel amp.
3rd Here it gets cloudy.
A) It is a mono channel amp. You run speaker wire from the amp to the sub.
B) It is a multi-channel amp. You bridge the sub.

If you have an amplifier that only allows on RCA input then please post a pic.
If your amp accepts 2 and you want to use 2 outputs from the head unit. Then connect the combined out puts into 1 input. DO NOT DO THIS.
