Hannah Z. ★★★★★

Plugged this harness into my Nissan and the Impulse 4.320 fired right up—the Y-split design made it a perfect match for the factory wiring. Sound is clean and zero noise, exactly what I wanted for a stealth install.

Robert ★★★★★

Installed this Y-ISO T-harness today and everything clicked right into place—the connectors matched perfectly with my Nissan's factory wiring. The 4-channel integration with the Impulse amplifier was seamless, no cutting or splicing needed. Definitely worth it for a clean, professional-sounding upgr

Jason V. ★★★★★

Plugged this harness into my Pathfinder and the Impulse 4.320 fired right up — no splicing needed. The factory connectors matched perfectly, and it really cleaned up the install.
