2 HU's to my amps?

[MrSo0h0o]

hey guys, as some of you know i just got an eclipse dvd unit and i have been playing around with it the past 2 days. i was originally gonna sell my pioneer HU but it kinda sucks cuz the eclipse doesnt play WMA and im not loving the layout. i was wondering if there is a way to hook up both HU's to my amps? so that i have a choice between the two(essentially using the eclipse only for dvd and the pioneer for music) any info will be great. thanks!

There are little RCA splitting boxes out there. Basically a switch between two sets to a single. Radioshack I know has them, but I'd buy elsewhere.

what you need is something like the Sony XA-39a. This is a small box with power, ground, and inputs for remote triggers to both head units, along with RCA inputs for F/R of both units and F/R RCA outs to amplifiers or crossover processors. It's not a real cheap device, but it works as a switching network so you don't get any feedback when using two head units in one system. It was fairly popular when we used to install cassette and CD heads in a car back in the 90s.. not so useful these days since a lot of head units have an AUX line input and generally handle everything most people want.

Could he run the audio output from the Eclipse into his Pioneer so that the Pioneer is always responsible for sound output? Or would this create some feedback or signal problems??? I don't know, I'm just trying to think of some cheap ideas...

i asked over at toyotanation.com and they told me i could just hook my pioneer up to my aux inputs on the brain and keep the pioneer at a set volume level and make the eclipse master volume. that could work, right?

if you have a universal AUX input, sure
