Package Includes: PACKAGE INCLUDES: (1) Rockville dB45 3200 Watt/800 Watt Dyno-Certified RMS 4 Channel Amplifier Car Stereo Amp, Loud!!; (1) Rockville RWK42 4 Gauge 4 Chan Car Amp Wiring Installation Wire Kit (2) RCA's. Complete amp + wiring solution built to pair the dB45's clean power with high-conductivity cabling for stable, noise-free installs in cars, SUVs, or trucks, saving time and ensuring compatible parts right out of the box. Dyno-Certified Power & Control: Rockville dB45 delivers 800-Watt Dyno-Certified RMS (200 W x4 @2-Ohm; 135 W x4 @4-Ohm; 400 W x2 bridged @4-Ohm) with Class-AB topology for musical detail. Fully adjustable 12 dB/oct filters, subsonic filter, and 12 dB bass EQ let you dial precise crossovers (HPF 15 Hz-1 kHz; LPF 50 Hz-3 kHz) for tight mids, clean highs, and solid bass without clipping or distortion. Engineered headroom keeps your system sounding clear at any volume. Pro-Grade Reliability & Safety: The dB45 uses a high-speed MOSFET supply, optical-coupled Class-AB stages, and studio-grade bipolar outputs for stable, low-noise performance. Full IC-controlled protection covers under/over-voltage (10 V/16 V), thermal, and short-circuit events, while mute-and-delay soft start prevents pops. An 8-volt preamp section, >150 damping factor @100 Hz, and three 35-amp ATC fuses ensure confident daily driving. High-Performance Wiring Included: Rockville RWK42 4-Gauge 4-Channel kit adds low-resistance power delivery and clean signal transfer. (2) 17' twisted-pair 100% copper RCA cables fight noise; SuperFlex PVC jacket routes easily and withstands −40 to 220 °F. Includes 17' 4-gauge power, 3' 4-gauge ground, remote and speaker wire, gold-plated AGU holder with fuses, loom, and install accessories for secure, tidy builds. System Flexibility For Any Build: Pair the dB45 with the RWK42 to power front/rear speakers or bridge for high-power components or small subwoofers. 2-Ohm stability, selectable crossovers, and strong S/N help create loud, clean daily systems for sedans, SUVs, trucks, and UTVs. With precise tuning, ample current delivery, and expansion-ready outputs, this bundle scales from factory upgrades to custom installs with confidence. The Rockville dB45 + RWK42 bundle combines a Dyno-Certified 4-channel amplifier with a true 4-gauge wiring kit to deliver clean power, smart protection, and low-loss signal paths for daily drivers and custom installs. Engineered for musical clarity and dependable output, the dB45 supplies 800-Watt Dyno-Certified RMS power with Class-AB warmth and control, while the RWK42 kit ensures that current and audio signals reach your speakers with minimal resistance and noise.

Designed around real performance numbers, the dB45 produces 200 W x4 @2-Ohm, 135 W x4 @4-Ohm, or 400 W x2 bridged @4-Ohm. Fully adjustable 12 dB/oct crossovers (HPF 15 Hz-1 kHz; LPF 50 Hz-3 kHz), a subsonic filter, and a 12 dB bass EQ make system setup straightforward-tightening midbass, cleaning up highs, and protecting drivers. A high-speed MOSFET supply, optical-coupled Class-AB stages, and studio-grade output devices are backed by IC-controlled protection, under/over-voltage safeguards (10 V/16 V), mute-and-delay soft start, and three 35-amp ATC fuses.

The RWK42 4-gauge 4-channel kit complements the amplifier with (2) 17' twisted-pair 100% copper RCA cables for superior noise rejection, SuperFlex power/ground with an abrasion-resistant PVC jacket rated −40 to 220 °F, remote and speaker wire, a gold-plated AGU holder with fuses, loom, and installation hardware. The result is stable voltage under load, cleaner signal transfer, and a tidy, durable install.

Ideal for powering front and rear speakers or for bridged high-power channels, this system fits sedans, SUVs, trucks, and UTVs. If you want verified power, flexible tuning, and pro-grade wiring in one package, the Rockville dB45 + RWK42 bundle is a smart foundation for a loud, clean, and reliable car audio build.
