FAQs

How does the RFDB4 differ from the RFDB1? The RFDB1 has four ports (two at 1/0 or 4 AWG, two at 8 AWG) for high-power multi-amplifier systems. The RFDB4 has two ports (both 4 or 8 AWG) — suited to smaller systems or as a secondary terminal for ground distribution.

Does this replace my existing battery terminal? Yes — clamps directly onto the battery post.

Sold as individual unit? Yes — two required for complete positive and negative installation.
