RCA cables

[TEutis]

I'm going to be upgrading the stereo in my boat. The marine head unit in there (I'm not replacing it) has only one set of RCA outputs. I will be running a mono amp and a jl audio 6 channel amp (e6450). Can I go into the mono amp, then back out through the output on that amp and then "Y" into the rca connections required for the JL audio e6450? The JL needs 2 sets of inputs - both on Ch 1&2 and 3&4. It can take the sum of those to configure Ch 5&6 without rca's. I have attached a diagram to help explain what I'm talking about. Thank you in advance for taking the time to help me out.

You need to read the specs on the mono amp and see if the RCA outputs are full-range. If they are you will be ok. If not just use Y-splitters at the deck. Then use another set of splitters at the 6 channel amp. I would suggest a line driver or a pre-amp EQ with front/rear/sub outputs though. You will get some signal loss splitting up that much. Or simply Get a deck with 3 RCA outputs. They can be had cheap on here or off E-bay. I run a Kenwood Excelon in my Mastercraft with no problems, and NO it's not a marine deck. Got it new for $169/shipped off ebay.

Hope this helps. good luck with the install.

Running it as you have in your diagram should be fine.

Having a passthrough on an amplifier that is filtered just doesn't make sense.
