Using two head units

is there some reson this guy wants 2 head units? I mean... if hes got some problem with changing CD's they do have this little thing called a CD changer lol, besides I dont think there is such a thing as an RCA switcher though I could be wrong but where's the practicality of having 2 head units?"Shiny chrome when used in conjunction with bikini models is particularly effective in inducing brain deficit disorder"

Maybe he wants to have 2 four channel amps for 8 different speakers in his car and listen to the concurrently. Lol...I don't know myself.~The Rookie~

Don't let the smoke out of your equiptment..it doesn't go back in.

2 four channel amps for 8 channels.. wont that be playing two separate head units? I wonder how anyone can put the two head units in sync. That must sound really interesting. Would one call that "music piglatin" or "miglatin"? Seriously, I think it may be for the different features of the two HUs and maybe he got them as gifts and each has its own sets of good features maybe?   As far as wiring them, I would think you can put Y cables and join the two HU's to the amp, but ask the customer to play only one HU at a time but not both together (unless he wants to hear the recently invented term miglatin).

You could do it with an RCA switcher that will automatically swicth when it senses a signal from one head unit or the other. But using this he won't be able to play them both at the same time. hopefully the head units he wants to use have both front and rear RCA outputs (makes the install easier I think). If not you might have to use LOCs on them and that could cause a distortion problem.Duane...

this guy isnt jamaican is he???... i see this all the time here... 2 different hu's strapped under the dash with plumbers tape, a pre amp (or 2), realistic supertweeters screwed down on rear deck... some real nightmares in wiring.... see lots of factory decks used in different cars..(ie. factory chevy radio in nissan sentra).. these are some of the things i deal with on a regular basis!!!

yes this can be done quite easily if you use the proper interface...we used to use one made by PIE but i havent seen it in the catalogue for a year or 2.... do a search for a multi head unit switching device.....Kevin Gerry

now it all makes sense. initially I thought the units were similar such as both being HU's with CD/Tuner etc. So they do different jobs and thats perfectly useful and quite cool actually. I wanted to do something similar, having a CD player/tuner and a screen. Any good ideas on whats a good screen to buy? Visor screens or in dash screen? I vote for visor screen to keep at bay from thieves but thats only my humble opinion.
