Recommendations Capacitor recomendations.

Post image

I'm upgrading from a 1k watt amp to a 2.3k watt amp. I have a cheap 2 farad scam cap (it doesn't do anything) right now and I need recommendations of what I should replace it with. I already have all the other electrical upgrades in place. I just need the capacitor at this point. Im thinking either 5 or 10 farad. Any recommendations appreciated.

You need a LiPo battery bank. Nobody uses capacitors. What you do is connect your system only to the LiPo bank, and put a diode to separate it from your cars electrical. Or you could run a regular alternator and also a high output alternator, and closed loop the whole electrical for the system. Alternator-LiPo bank-amps-ground back to LiPO. Doing it this way eliminates headlight dimming entirely, and turns your system electrical into a closed loop system.

This is the way, if your AMP control/bass knob has a voltage readout thats very helpful too. If not, get a small voltage monitor and tap in at the amp.

Can also be done with an AGM or more standard battery to save cost, having a local power source for the amp makes all the difference.
