Overview

The Rockford Fosgate Signal Input Harness Kit is a replacement part designed for T/TM/M5 series compact amplifiers. It features a 4-pin connector to low-level RCA, with the option to be used for high-level inputs by cutting off the RCA ends.

Show original supplier description
The Rockford Fosgate Signal Input Harness Kit (1130-70118-01) is a direct replacement for the signal input harnesses found on select Rockford Fosgate compact Power and M5 series amplifiers. This kit ensures proper signal transmission by converting a 4-pin connector to low-level RCA outputs. It also offers versatility, allowing for use with high-level inputs if the RCA ends are modified. This systematic color-coding simplifies the wiring process, ensuring accurate connections to your amplifier. The specifications for this harness include a 4-pin connector type that interfaces with female RCA connectors. The cable itself measures 13 inches (33.02 cm) in length, with the total length including connectors being 15 inches (38.1 cm). It's important to note that these harnesses are not interchangeable with other Power compact amplifiers due to a smaller 4-pin molex connector size. This specific harness is compatible with the M5-1500X5 (2021-Current), T1000X5ad (2016-Current), and TM1000X5ad (2016-Current) Power Compact amplifiers. Always verify fitment using the compatibility chart before purchase, as restocking fees may apply to returns.
