Im not an expert but he stated its a 160 volt power supply. Its 160 volt, not 160 amp. It has to do with the circuit of amplifier, thats how it is possible.
looking and the voltage drop at 318 amps and with car off, those batts are a lil weak. Im getting a 11.6 drop on 100 amp load on 1 used $25 ups battery.
i love the 2300 model, so tiny, not alot of parts but expensive //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
