KSSX (95.7 FM), also known as Jam'n 95.7, is a radio station located in San Diego, California. The station airs an Urban Contemporary format with an Heavy lean on Hip-Hop and R&B,and is one of seven stations in the market owned and operated by iHeartMedia. The station's studios are located in San Diego's Kearny Mesa neighborhood on the northeast side, and the transmitter is in La Jolla.

This station has its roots as a Class A (local) station at 95.9 MHz known as KKOS, which was previously known as KARL (a MOR station from 1965-1979) and KUPR. During this period the station had various formats, including adult contemporary, CHR, and AAA.

However, an interference problem in Mexico ended up resulting in changes to KKOS. At the time, a Tijuana station broadcast on 95.7, XHKY-FM. XHKY was causing interference to KKOS. Ultimately, KKOS and XHKY reached a deal, which was agreed to by the FCC and SCT; on September 15, 1995, XHKY moved to 99.3 at 25,000 watts, KKOS moved to 95.7 at 25,000 watts, and the previous occupant of 99.3, XHATE-FM Tecate, moved to 95.3 MHz.

The day of the frequency change, KKOS became KUPR, still keeping the AAA format. On November 22, 1996, the station began stunting with country as "Your New Country, 95.7 KUPR". On March 5, 1997, the station flipped to Urban AC as "Magic 95.7" under new callsign KMCG.
