4 channels to 8 channels RCA'a

12 posts in this topic

So I have ran the front and rear channels to the 2 amps I have in the back what I have currently are Y-Splitters. Is there a better option for this? I am curious because it seems if I use the splitter I have a weaker signal.

does your amp have a line out?  if so then you can daisy chain the rca over.  it's a much cleaner install and you have less connection points to come loose.

Uploading photos s we could look at what i'm looking at. No there is no line out on the amps.

don't look to have a line out.  guess y's or a cock box may be your only options.

spendy yes.  but likely the cleanest way possible of doing what you need with out line outs on an amp.

Use your voltmeter and measure the output to confirm.  Measure the output on one of the RCAs, positive led to center pin, negative lead to outer shield, set to AC volts without the Y splitter, then put the Y splitter back on and measure the output at either side  of the Y splitter.

If you send an email to Scott Bowman or PM him on facebook, he'll give you better pricing and options. You just gotta tell him what it is you want. I've got two from him now.

Splitting each RCA once is perfectly fine as far as signal goes. You have 3 pairs from your head unit right? front, rear, and sub? If that is the case then unless it is limiting fading or something I wouldn't worry about it too much.

im not certain, wish someone could demonstrate i, but since its ac voltage i think it doesnt matter how many times you split it it will stay the same. 

 

edit what i mean is its paralleled not series, maybe the ac part is irrelevant.

The input resistance on the amps should be so high that splitting shouldn't reduce the signal much if at all. This is why the cock box works so well. It's just a huge splitter no power or anything. I run an EQ with a built in per amp to jack the signal. That way I can turn the amp gains way down.
