Impressive sound pressure and power
SP 4.900 is the first Hertz amplifier featuring the renewed Hertz ADC (Advanced D-Class) output stage, reaching up to 85% efficiency and delivering an impressive power rating of 160 x 4 (4Ω) W RMS or 500 W x 2 (4Ω) W RMS when bridged, with an ultra-compact size of 211.6 (8.3) x 130 (5.1) mm (in.).
Hertz ADC technology ensures SP 4.900 overtakes the usual ultra-compact amplifier performances, delivering an outstanding 105 dBA S/N Ratio and 0.02% THD specifications, and almost completely eliminating EMI and RFI noise, for peerless sound quality.
This versatility is perfect to drive high power (4Ω) front speakers with a bridged (4Ω) subwoofer.
SP 4.900 is fully protected against overheating and DC outputs, immediately switching in protection mode (red led on) to save your speaker system.
The IP55 certified Aluminum chassis offers maximum protection against humidity and external agents and the absence of internal cooling fan prevents internal accumulation of dirt. SP 4.900 main board has conformal coating layers to prevent harm caused by internal condensation, a condition that can happen when warm, moist air meets the amp chassis of a lower temperature.
- Up to 85% efficiency thanks to ADC (Advanced D-Class) output stage
- USS (Universal Speakers Simulators) allows SP 4.900 to work with head units featuring the “speaker load detection” circuit
- 160 x 4 RMS (4Ω) with ultra-compact size (211.6 x 130 mm)
- IP55 aluminum chassis for maximum protection against humidity and external agents
Being ultra-compact with impressive power, SP 4.900 is the ideal choice for Motorcycle application and for under-seat in sports cars and behind-seat installations in trucks.
The versatile crossover filters and control knob are all located on a single side, to allow an easy calibration when the product is installed.
The filters section includes extremely flexible high-pass and low-pass crossovers, adjustable from 50 Hz to 5 kHz with 12 dB/Oct slope. Together with a bass-boost control (45 Hz, 0÷8 dB), they allow both front channels to be configured for full-range operation, or for use with a subwoofer and related speakers.
The high-pass crossover can also be used to optimize the performance of SPL Show NEO high-efficiency coaxial speakers, the perfect partners for SP 4.900.

FAQs
Q: How do I choose the right amplifier for my speakers or subwoofer?
A: Match the amplifier's RMS output per channel to the RMS handling of your speakers or subwoofer at the same impedance. The Specification tab lists the power figures. If in doubt, contact CEN with your setup and we will recommend a match.
Q: What wiring do I need to install this amplifier?
A: You will need an amplifier wiring kit sized to the amplifier's power draw, typically including power and earth cable, a fuse, RCA leads and a remote wire. CEN stocks complete wiring kits, and the amplifier's fuse rating is the guide to the cable gauge required.
Q: What class of amplifier is this and does it matter?
A: Class D amplifiers are compact and efficient, ideal for subwoofers and modern installs. Class AB designs are traditionally favoured for outright sound quality on mid and high frequencies. The class is listed in the Specification tab where provided.
Q: Will an amplifier work with my factory head unit?
A: Yes, in most cases. If your head unit has no RCA outputs you will need a line output converter to feed the amplifier a clean signal. CEN stocks line output converters and can advise the right one for your vehicle.
Q: Can CEN install this amplifier?
A: Yes. CEN offers professional amplifier installation from our Nottingham premises, including secure mounting, wiring and setup. Contact us to book.
