- Package Includes: (1) RTB80A 8" 400 Watt Powered Subwoofer Bass Tube + MP3 Input, (1) Rockville RWK81 8 Gauge Complete Amp Installation Wire Kit with 100 % Copper RCA
- Power & Low-Frequency Performance: The RTB80A packs a focused 8-in woofer in a vented tubular enclosure that delivers punchy, deep bass for cars. Specified 400-Watt Peak / 200-Watt RMS with an integrated amplifier listed at 250-Watt RMS, the tube offers an adjustable low-pass crossover and up to 18 dB boost at 45 Hz for impactful low end across a wide frequency range (30 Hz–200 Hz) while maintaining clarity and control.
- Installer-Friendly mounting & inputs: RTB80A includes four mounting legs and Velcro straps for secure, non-permanent placement so you can try corner, rear or front loading to tune cabin response. Inputs include speaker-level and RCA line-level as well as an MP3 input for quick playback. Simple power, ground and remote hook-up gets the tube running without custom enclosures or complex wiring; compact 8.75 × 19 in sizing fits most vehicles.
- Pro wiring kit with low-loss construction: The RWK81 8-AWG installation kit supplies 17' 8-AWG SuperFlex power cable, a 17' 100% copper twisted-pair RCA, 17' speaker lead, 3' ground, gold-plated 60A AGU fuse and holder, 7' split-loom and accessories (ties, ring terminals, butt connectors, spades, grommets). The RCAs use blue/silver twisted-pair in a clear jacket; soft abrasion-proof PVC jacket and low-resistance design simplify installs and improve power transfer.
- Durable build and tuned enclosure: RTB80A features a molded steel woofer grille, rear aero-vent bass system and aviation-grade tweed cover with embroidered logo for lasting looks. Four steel mounting brackets plus two canvas Velcro straps are included for secure placement; sensitivity is 105 dB and the tube form factor focuses bass pressure from both the woofer face and tuned port. Rockville production testing and QC procedures support consistent, reliable operation.
