FAQs

How does the dual wiring topology work in the RFK4D? The main 4 AWG power wire runs from the battery to the included distribution blocks — each block then feeds a 6-foot 8 AWG run to each individual amplifier. This is the standard star-distribution wiring topology for dual amplifier installations — one protected main run splits to two independent amplifier feeds.

Are two separate RCA cables included? Yes — two 16-foot twisted pair RCA cables are confirmed in the kit, one for each amplifier.

What are the distribution blocks in this kit? Two 4 AWG distribution blocks are included — these are the inline distribution points between the main 4 AWG run and the 8 AWG secondary runs. Confirm the specific block specifications from the official product page.

Is remote wire included? Yes — 20 feet confirmed.
