Car Speaker and Amplifier SCOSCHE OEA4 4-Channel Adjustable Factory Amplifier Interface 4-CHANNEL CAR STEREO SPEAKER LEVEL CONVERTER; USED TO ADAPT AFTERMARKET CAR STEREOS TO ORIGINAL EQUIPMENT AMPLIFIERS; WORKS WITH MOST FACTORY AMPLIFIED SYSTEMS SUCH AS JBL/PREMIUM & BOSE;
Pansonic CY-PA4003U 4 Channel Power Amp Make a Powerful Sound StatementHigh efficiency is a key requirement for amplifiers, particularly when it comes to driving powerful speakers over long periods using the car's battery power. To attain high efficiency, the power supply drive stage employs MOS-FET devices having low internal impedance. This helps preserve the transparency and crispness of the original audio signal for faithful audio reproduction through the connected speakers. Maximum output power is an impressive 1000W (250W x 4), thanks to high efficiency with low heat generation and reduced load on the car battery.Low-Pass Filter for SubwooferAmps with a built-in low-pass filter simplify upgrading to a subwoofer system. You can adjust the cutoff frequency continuously from 50Hz to 250Hz for optimum matching between the subwoofer's range and that covered by your other speakers.Line-Out Jacks for ExpansionWhen configuring a sophisticated car audio system, line-out jacks make all of the difference. They let you easily connect multiple amps, while keeping the wiring neat for an attractive appearance."Intelligent" Bass Servo CircuitIn comparison with the midrange and tweeter units, the woofer has a relatively higher moving mass, heavier voice coil and larger inductance, so it needs more current to start moving. This causes the bass to lag behind the mid and high frequencies, resulting in unnatural tonal coloration. Furthermore, because of its longer throw, the woofer's voice coil has a greater tendency to deviate from pistonic motion, resulting in non-linear dynamic distortion. To overcome these woofer shortcomings, our "intelligent" bass servo drive circuit can feed very high current at the moment of start-up and instantaneously detect and correct the state of voice coil movement to maintain pistonic motion and avoid non-linearity. The result is bass that is more coherent with the rest of the frequency spectrum, achieving greater fidelity to the original sound.Versatile Bridgeable AmpWith a 4-channel amp like this CY-PA4003U, you can bridge it for 3-channel or 2-channel output. Drive four speakers, two speakers, or two speakers and a subwoofer, the choice is yours. This amp has the flexibility to fit your car audio system.Power Output (maximum) 225W x 4 Power Output (at 4O and = 1% THD+N) 64W x 4 Signal to Noise Ratio (1W into 4O) 85dBA THD (1kHz) 0.02% Frequency Response (±1.0dB) 10Hz - 30kHz Crossover Frequencies 50Hz - 250Hz Bass Boost 0dB - 15dB Input Level Adjustment 200mV - 6V Speaker Impedance 4Ù Current Consumption 24A (64W x 4, 4O) Line-Out JacksGold-plated RCA Connectors Gold Plated Speaker Terminals Speaker Level Input Mix Mode Operation Bridgeable 4-, 3- or 2-channel Servo Drive Circuit Yes, for PWM DC-DC converter Thermal shutdown protection circuit Yes Indication LED Illumination Blue Dimensions (H x W x D) 2 7/16"'' x 13 1/8"'' x 11"''
Component speaker - A component speaker is a car audio speaker matched for optimal sound quality. Typically a pair of tweeters and mid-bass drivers are matched with a crossover to limit the frequency range each speaker must accurately reproduce. Leslie speaker - The Leslie speaker is a specially constructed amplifier/loudspeaker used to create special audio effects. Named after its inventor, Don Leslie, it is particularly associated with the Hammond organ. Master volume controls - There are several ways to tame the volume of a guitar amplifier. Of course, you could use an amplifier that's small enough so that its natural volume is what you require, but that wouldn't be any fun if you want to crank that 100 watt Marshall amplifier throught its 412 speaker cabinet. Orange Amplification - Orange Amplification is a British electric guitar amplifier manufacturing company, famous for its distinctive bright orange tolex covering on amplifier heads and speaker cabinets. It was founded in 1968 by Clifford Cooper of London. carspeakerandamplifier
