If you need to install an aftermarket amp, but pulling the factory headunit isn’t an option the SC4.1 is your solution. The SC4.1 is a premium quality 4 channel speaker level to 6 channel line level signal converter. Channels 1~4 are full range, and channels 5~6 are dedicated sub outputs with a built-in 300Hz 12/dB low pass filter. The inputs feature summing capabilities and can handle up to 25 watts making it compatible with virtually any factory system. You can count on noise free integration via top shelf components such as TI op amps mounted on an FR4 circuit board, and unlike cheaper products it’s active circuitry will not induce stressful loads on your factory system. The RCA outputs are adjustable from 0.05- 4V for precise level matching. To add to this unit’s flexibility, you can choose from auto signal sense or manual 12v remote turn on triggering. All these features fit in a tidy little (4.61″x 3.75″x 1.07″) package aluminum chassis.
