Amp install kits use high‑conductivity conductors such as oxygen‑free copper (OFC) or 100% pure copper for power and ground wiring. RCA interconnects are often made with silver‑tinned OFC conductors to improve signal transfer and corrosion resistance.
RCA lengths vary by kit. Common examples in the listings include a pair of 17‑foot (≈5.2 m) RCAs or interconnects specified at 6.0 m. Always check the product details for the exact length included.
Kits that include amplifiers display RMS power ratings. For example, a listed mono subwoofer amplifier shows 1250 W RMS at 1 Ω, 750 W RMS at 2 Ω, and 400 W RMS at 4 Ω. Always check the product specifications for exact ratings and test conditions.
