1.5 Connecting the power supply
The i-soamp-4‘s standard delivery is with
an ISO power adapter. Due to different
connection pin confi gurations of different
automotive producers for the 12V Dauer-
plus power voltage in the ISO plug, the
i-sotec power adapter has the capability to
solve this problem. The power adapter is
connected between the OEM radio and
the original cable harness, like the loudspea-
ker adapter.
1. ISO power adapter connec-
ted to the car‘s cable harness.
2. Plug adapter for Constant
12V („Memory“, No. 30)
3. Plug contact optionally inser-
ted into the No. 2 adapter to
which Constant 12V is con-
nected. (To check, please use
a voltmeter or a test lamp).
4. plug connected to i-soamp-4 main cable
harness. On this plug connection other
model-specifi c adapters can be connec-
ted to the i-soamp-4.
5. Radio
The i-soamp-4 has a maximum power re-
quirement of 15A per amplifi er. With a few
cars, and when two amplifi ers are connected,
the radio wiring cannot cover this power re-
quirement. In that case the i-soamp-4 has to
be connected directly to the battery.
1.6 Notes on direct connection to the
battery:
Prior to any electric connection of the to the
12 V power system in your car, make sure to
disconnect the battery!
At fi rst , look for a suitable grounding point
(Gnd, Common) on the chassis of your car
in the vicinity of your i-soamp-4 where you
