Well http://www.ebay.co.uk/itm/30-FARAD-CAR-AUDIO-DIGITAL-AMP-POWER-CAPACITOR-CAP-KIT-/350474199233?pt=UK_Audio_TV_Electronics_In_Car_Entertainment_GPS_Car_Amplifiers_PP&hash=item5199e3e0c1 is the one i got, Really good bit of kit, stopped my lights from pulsing in the dark, and the little blue light is pretty cool I would let it go for 80 posted though, just taking up needed space. I will throw in extra live, ground and REM cables to take to amp as well if that would help. Cheers
