I'm running 2 200w amps, 1 1000w amp & active crossover in a classic mini. Needless to say a power cap was needed. I had been keeping an eye out for a power cap of sufficeint power for a while, then came across this. 1.2 farads @ this price couldn't go a miss. Has made a massive difference! Much cleaner, much tighter bass, much louder! Thanks.
