- 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
- Powerful Low-Frequency Output: The RTB80A features an 8" high-power woofer in a vented tubular enclosure driven by a built-in amplifier. Rated 400-Watt Peak / 250-Watt RMS with an integrated 250-Watt RMS amplifier, it includes an adjustable low-pass crossover and up to 18 dB boost at 45 Hz to deliver punchy, tunable bass across a 30 Hz–200 Hz range. Sensitivity 105 dB ensures strong output in small cabins.
- Installation Simplicity: Designed for plug-and-play installs, the tube includes four mounting legs and Velcro straps for non-permanent mounting, speaker-level and RCA line-level inputs plus an MP3 input for quick playback. No separate amp or enclosure required; simply connect power, ground, remote and signal. Compact dimensions (8.75 x 19 in) fit most vehicles and allow flexible placement options.
- RWK81 Complete Wiring Kit: The included RWK81 supplies 17’ 8-AWG SuperFlex power cable, 17’ high-grade 100% copper twisted-pair RCA, 17’ speaker lead, 3’ ground, a 60A AGU gold-plated fuse and holder, 7’ split loom and installation accessories. The soft abrasion-proof PVC jacket withstands -40 to 220°F, while superior RCA shielding and low-resistance construction improve power transfer and reduce interference for reliable installs.
- Versatile Placement and Tuning: Rockville Bass Blaster tubes are designed to be experimented with—corner load, rear load or front load the tube to explore cabin response and find the best low-end punch. No permanent installation is required; try multiple placements using included mounting legs and Velcro straps. This flexibility lets you optimize bass performance without sacrificing space or requiring custom enclosures.
