Soundstream AR4-2000D 2000W 4 Channel Class A/B Arachnid Series Car Amplifier

Soundstream AR4-2000D 4 Channel Class A/B Arachnid Series Car Amplifier 2-channel & 4-channel models take every advantage afforded by Class A/B linear amplifier technology, a compromise of performance and high-fidelity characteristics. 4-ohm or 2-ohm speakers Active 12dB/Octave Crossovers & Bass Boost Active crossovers built into an amplifier are the most efficient type of crossovers to use in car audio systems.  Passive crossover circuits (like those that come with speakers) can have a power loss of 0.5dB or more.  Active crossovers have much lower power loss, if any at all.  Simultaneously, active crossovers protect speakers from damage by harmful frequencies, and preserve optimum performance. Low Level RCA Input & Pre-Amp Output Connect the low level (pre-amp) audio output of the car stereo to the amplifier, using good quality twisted pair RCA interconnect cables.  Twisted pair RCA cables are optimal for their noise rejection properties.  The amplifiers pre-amp outp
