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 output daisy-chains the audio signal to multiple amplifiers of complex audio systems.
Military Grade FR-4 PCB w/ MOSFET Power Supply
- FR-4 circuit board using a woven fiberglass cloth impregnated with an epoxy resin (to provide heat protection)
- Excellent electrical insulation properties and heat resistance even when exceeding 260OF.
- MOSFET power supply is the stable & efficient conversion of a vehicles Alternating Current (AC) power for speakers and handles 2Ohm Loads
Direct Short, Thermal, & Overload Protection Circuits
- Conventional amplifier circuitry includes a self-preservation mode, which temporarily shuts down the amplifier, protecting it from stress and risk of damage.
- Protection triggers include speaker output direct short if Impedance is less than what is recommended
- Read the Owner's Manual to avoid Damaging the Amp.
2-ohm & 4-Ohm Bridged Minimum Impedance Stability
- An amplifiers impedance stability is its ability to continuously power speaker(s) of no less than the given impedance per channel, without the risk of damage.
- An “Ohm” is the measurement of resistance (impedance) of a speaker's voice coil, which indicates how much the amplifier will resist the flow of power to it.
- Speakers are commonly available in a variety of voice coil configurations and impedances, so be sure the configuration of yours will be no less than 2-ohm.
