Marine Audio Question...
Discussion
Afternoon!
Mightn't be the right section, but as some clever individuals hang-out in here....
I am going to be installing ''some kind of system'' in my boat before she goes back in in a couple of months time, and have an idea of how I want to do it. Question is, is it feasible...?
As I will be using the iPod (other MP3 players are available) as the source the vast majority of the time, I didn't want to spend 2 or 3 hundred quid on a tuner/cd player which would effectively be redundant in actually playing music...
I have an Alpine 4 channel amp and 4x Alpine marine speakers and so my plan would be to wire-up a 3.5mm jack to a pair of RCAs which would be connnected directly to one of the amp's inputs, just like a pre-out would from a head unit...
Would this work? I appreciate that it would'nt be a 4-volt pre-out like a head-unit might be, but would the amp be able to turn this potentially lower voltage signal into a powerful signal to feed the speakers...?
I realise that unless I split the jack signal into 2 pair of RCAs I would only have 2 channels not 4, but in theory is this possible?
I was looking at something like this....

This may work depending on the input sensitivity of the Alpine amp, I think you'll run into some voltage/noise problems like you say if your amp is expecting to see and higher voltage at it's inputs though- your ipod will be pumping out 2-3v at most from it's headphone socket, obviously your ipod will have to control the volume.
Tbh you can pick up a half-decent Sony head unit with aux in for as little as £60 at the moment and you'd have the cd player and tuner there if you wanted them.

Just buy a lead and give it a go.

Nothing to lose for a fiver.
Four channel amp doesn't mean 4 channel input it just means seperate amplification for each of the four channels. Still takes stereo signal and outputs to all four channels.
But better off getting a Boss or Fusion head unit that takes the iphone etc inside and charges it all at the same time.
