Why This Kit
MATCHED.
TUNED. DONE.
The Dual 10" 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 25-D2s wired to present a 1Ω load to the GZIA 1500.1, delivering 1300W RMS. The signal interface eliminates noise. The wiring is the right gauge. And the sealed enclosure is built for two subs.
