Zapco c2k-9.0xd in good shape. Beast of an amp it just needs a symbilink which can be easily obtained for cheap. These amps don't have rcas built in so they use a symbilink which gives a more balanced and clean signal from the head unit to the amp or you can get the symbilink cable for $18-$28 depending on length
It's the 2ohm mono version
