Reconfigure Stereo - Seeking guru opinion

[jtrezon]

I am replacing (4) in-boats with new Exile 6.5's, and I plan to add a 4ch amp as these are currently powered by the HU. I would also like to use the fader control on the HU to fade between the tower and in-boats so I came up with a block diagram that I think with work I haven't done much audio install work, so I'm seeking a more learned opinion on whether or not there is a better solution given the components I have to work with. Appreciate any comments.

scratch the electronic crossover and get an EQ instead (which has the crossover built in). That will work a lot better than the fader for tuning the volume between zones, and it will also have the sub control too. From a value proposition, the clarion EQS746 cannot be beat: http://www.amazon.com/Clarion-EQS746-Graphic-Equalizer-Crossover/dp/B000EZV3T8

Impedence doens't look right to me. I'm assuming you are wiring those in parallel with the way the diagram is, which would mean you'd be running 2 Ohm impedence, rather than 4.

I Agree... changing to an EQ would be better...I might think about that, but Id have to start over and re-route all the RCA's. I should have said the crossover is already installed near the amps under the passenger comp....currently connected to the tower speakers. I have room for one more amp so I was going for the quickest install. The only wiring I need to add is in RED (See edited image)

Each speaker has its own 4ohm channel....using 4ch amps. Did I mess that up?

Thanks again

I don't understand why an electronic crossover is being used since just about every available amplifier in the past 25 years already contain a crossover.

But if you are using some REALLY old amplifiers without crossovers, the EQ mentioned only has a non-defeatable lowpass for the sub channels and no highpass for the tower and in-boat zones. And you would miss the highpass.

Let's just call it an RCA splitter in a box... which is basically what it was originally put there for. I do, however, like the remote sub control....which I wouldn't have otherwise.

Your diagram only shows 2 inputs per amp for 4 speakers. But yeah, if you have 4X amps rated at 4 Ohms, then you should be good.

Why not a 6 chnl amp for the 3 pair of in-boats and a 2 chnl for the 2 pair pair of tower speakers? The 6 chnl would only require a single pair of RCA's, which could be split to the powered sub. The 2 chnl would only require a single pair of RCA's.

Wet Sounds HT-6 and HT-2.
