Why This Kit
MATCHED.
TUNED. DONE.
The Dual 12" Radioactive Kit isn't a collection of random components thrown together — it's a dual sub system where every piece was selected because it works correctly with everything else. Two GZRW 30-D2s wired to present a 2Ω load to the GZCA 1500.M2, which delivers 1400W RMS into that load. The signal interface eliminates noise. The wiring is the right gauge. And the sealed enclosure is built for two 12" subs.
