Other features include a subsonic filter, a fully adjustable bass equalizer, mute and delay soft start technology, a phase control switch, and a dashboard subwoofer control for added convenience. The dB14 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free music playback at all levels. Description of RWK41 : The RockvilIe RWK41 4 AWG (American Wire Gauge) amp kit has the following differences over other amp kits on the market at this price point. 1. Our RCA cables are 100 % copper. These are top of the line RCA cables 2. Better Resistance: The only thing that really matters with wires is the resistance rating. This is a measurement of conductivity and how much signal is loss per foot of wire. Since RockvilIe wires are made with around 3 times as much copper as any other wire at this price point, these wires had a much better resistance rating which means they will transfer more power
