The link1000.5plus is the perfect complete system amplifier. One of the drawbacks of most 5-channel amplifiers is that while there is usually enough power for the front and rear main speakers, the power left over of the subwoofer is limited. Not so with the link1000.5plus. Channel 5 produces a robust 500 watts RMS @ 2 ohms, enough for most subwoofer systems. Like all Wāvtech amplifiers, the link1000.5mini has built-in adaptive loading and can accept up the 40V of input. The link1000.5mini features built-in summing for up to 6-channels of input, so you won’t need to purchase an external processor in applications where a full range signal is not present. Like all Wāvtech amplifiers, it is compatible with Start/Stop systems. It also features 12dB per octave crossover on the 4 main channels and Wāvtech’s proprietary bassFREQ preamp with 24dB crossover and subsonic filter on the mono channel. The optional linkRC can be used to control the level of the subwoofer from the front of the vehicle. link1000.5plus Features 1000 Watt 5-Channel Amplifier Main Channels 75 watts x 4 @ 4 ohms 125 watts x 4 @ 2 ohms 250 watts x 2 @ 4 ohms BTL Subwoofer Channel 300 watts x 1 @ 4 ohms 500 watts x 1 @ 2 ohms Small Footprint: 11.9”x5.5”x1.65” Variable HP Crossover (-12dB/oct) with 1x/10x CH1/2 Variable HP/BP/LP Crossover (-12dB/oct) CH3/4 Variable Low-Pass Crossover (-24dB/oct) CH5 Variable Subsonic Filter (-24dB/oct) CH5 Adjustable Parametric EQ CH5 Remote Level Control (RLC) w/Optional linkRC bassFREQ Bass Processor w/Parametic EQ CH5 Active Thermal Management Start/Stop System Compatible Adaptive OEM Load Technology 40V Input Capability Differential Balanced Inputs Variable Gain Adjustment w/Clip LED Auto Turn-On via DC-Offset or Audio Signal Detect Adaptive OEM Load Technology Locking Detachable Hi-Level Speaker Terminals Professional Grade Panel Mount RCA’s Compact Aluminum Chassis w/Detachable Mounting tabs
