Blaupunkt installation instructions GTA 250 amplifier, Applications and loudspeaker connection

GTA 250

Fit the amplifier in a suitable location, e.g. beneath the seats or in the trunk (Fig. 1). The mounting location must also be dry, and provide sufficient ventilation for cooling of the amplifier. Use cable grommets when pass- ing cables through holes with sharp edges. Use loudspeakers with an impedance of 2 to 4 Ω (see table or installation drawing). Observe the max. power handling specifi- cations (music output). Do not connect the loudspeakers to ground; only use the termi- nals provided. The cross-section of the pos- itive and negative cable must be at least 6 mm2.
