Hi All,

I have a JBL GTO 75.4 II amp connected and Im wondering about the REM
feed.

My head unit doesn't have a remote feed to auto switch on (via the
REM) so I can either wire in a seperate switch and feed from the +12V
side or leave it on all the time. I dont want a switched live
otherwise the key will need to be in the ignition...

Question is how many Amps will the amp draw when its switched on but
not being driven by a head unit? In other words will it flatten my
battery over the weekend if i dont use the vehicle?


It depends on the amp, but it'd be marginal at best. I don't know
about your amp specifically.

What type of head unit do you have that doesn't have an electric
aerial wire?

Cheers,

Colin.


Colin,
Its actually a 12V car computer thats connected. I have tried to take
a line from the power supply that feeds the actual computer to the REM
input and this does switch the amp on and off with the computer but
that introduces a large pop in the speakers when it starts up.

My other option is to introduce a timer into this REM wire such that
the PC starts up and then say 5s later the REM line is made live
starting the amp..

If the PC is switched on first and then the amp (5s or more later)
there is no problem, only when the amp turns on at the same time as
the PC and it begins to boot.
