Many in-stock orders ship within 1-2 business days, but timing varies by item. Custom, built-to-order, oversized, special-order, and supplier-direct products may need extra processing time. Free shipping applies to qualifying orders over $99 within the contiguous US. Freight items may require delivery coordination; any shipping exceptions are shown before checkout. Approved returns may be subject to a restocking fee.
Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.

Two 18" monsters, the biggest amp in the Rebel line.
The Monster Bass Bundle pairs two American Bass Godzilla 18" subwoofers with the VFL REBEL-8000.1 monoblock amplifier — the flagship of the REBEL line. These subs are rated 4,700W RMS each, well beyond what any single amp can fully feed; the REBEL-8000.1 delivers 4,300W @ 2 Ohm, so the amp is the ceiling here rather than a full power match. Builders running a single amp get massive headroom and clean output — a second amp or higher-power setup unlocks the rest of what these subs can take.

Installation Notes
- Power note: the REBEL-8000.1 does not fully match these subs' 9,400W combined RMS rating — 4,300W @ 2 Ohm is well below their ceiling. This is intentional headroom, not underpowering damage risk; treat it as room to add a second amp down the line.
- Enclosure not included. Recommended: ported, sized per sub's spec sheet.
- Wire each sub's coils in series (4Ω), then wire the two subs in parallel for a 2Ω final load.
- Pair with an ABLT-80 (80Ah LTO) battery and dual 4/0 Gauge wiring kit for stable voltage under load.
- All components ship separately from their respective warehouse locations.
