It depends what your overall goal is with the car in the future. Most seem perfectly content with the L7 (HK) system but the base (HiFi) system provides an easier upgrade path if you eventually plan to use aftermarket amplifiers.

The BSW Stage 1 system is an effective, drop-in upgrade for either the base (HiFi) or HK system. The HK option will also give you some DSP capabilities, a 7-band EQ and better under-seat midbass drivers.
