GENERAL INFO ABOUT WIRES

INSTALLATION

To install this SPECTRON amplifier, you have to buy additional accessories like power
cables, RCA interconnects, main fuse holder, i.e. to properly connect your amplifier to
the on-board voltage system in your verhicle and the installed headunit. To obtain
best performance and power output, it is recommended to use good quality accessory
material only. Furthermore, consider a safe mounting of the amplifier, sufficient
ventilation, convenient accessibility of all the side panel controls a.s.o.
Please note that - because of possible interference problems with the existing car
electrics and electronics - the routing of the RCA signal cables and the chassis ground
connection are crucial steps for the install of this amp, and care must be applied to
obtain a noise free and reliable performance.

MAIN POWER CABLE CROSS SECTION

The minimum power cable cross-section for this SPECTRON amplifier is 10mm
intend to bridge this amplifier driving a subwoofer, or if two amplifiers are to be
mounted in your verhicle, the minimum power cable cross section is 16mm
SP-A1500D asks for 20mm
These recommendations guarantee troublefree operation of your amp(lifiers), giving
you full power output. Using main power cables with smaller cross sections may
result in over-heating of the internal amplifier circuitry and elevated distortions.

RCA INTERCONNECTS

Use at least double shielded RCA interconnect cables. Keep in mind, that the RCA
interconnects should always be kept far away from any potential sources of electrical
interferences, for example try ro avoid crossing electronic vehicle management
systems (like engine computers, relays, wire harness a.s.o.).

MINIMUM SPEAKER IMPEDANCE LOAD

The internal amplifying circuitry and the heat dissipation capacity of this amplifier' s
heatsink has been designed to cope with 2 ohm impedance loads in stereo mode or
4 ohms in bridge mode. Therefore, you can drive 4 to 2 ohm satellite speaker systems
– or 4 ohm subwoofer systems in bridged operation mode. Do NOT operate this amplifier
bridged into 2 ohm loads, the amp electronics may get damaged!!!!
