Any issues with Y-spliiter for RCAs????

[budahbuddy803 10+ year member]

I have the kenwood XR900-5. I want to use it as a 3 channel amp. 1 channel (bridged) for my driver midm 1 channel (bridged) for my passenger side mid, and 1 channel for the sub.

Because I am running my HU (Pioneer 3700BHS) in active mode, I will only have the rear and sub RCAs running to the amp. The front RCAs from the HU will go to a separate 2 channel amp for my tweeters.

I have called kenwood's tech support and they say that in order to run both "A" and "B" channels bridged, I need RCA inputs to both channels.

The only way I can do that is with Y-splitters (1 female to 2 male). I believe that this will split the voltage from 4V output from the HU to 2V input to the amp on each channel that is split.

What are the negatives of running the RCAs this way? I imagine I will have to play around with them to figure out which set controls the left mid and which set controls the right mid, but basically one of the RCAs from the HU should be left and one should be right, correct?

It doesn't split the voltage, it splits the amperage, you should be fine.

I'm not surprised that's the case. That's what I get for listening to tech support from crutchfield. Trying to get this response from crutchfield and kenwood technicians is like pulling teeth and then they pull the wrong one.

So no issues or disadvantages to doing this? Thanks for the reply.

its a bit complicated, you need to know the input impedences of all your equipment then do simple math V=IR to calculate what happens when they're all run in parallel.

dont worry about that though, ive run up to 3 splits off a single rca and it was fine, as long as you're boosted up above 2-3v before the splits. just need to adjust the gain with all the inputs in the amps in order to simulate real conditions/drop.

You'll be fine. Use a shielded RCA splitter.

You should be fine. I used the Y-splitters to run signals to separate amps. Works fine.
