Man i'm not an audio expert but three capacitors sounds like overkill to me. One farad is usually enough for regular non-competition car systems. IMO just run the 1 farad capacitor and ditch the two 0.5 ones. Also be careful when messing with any capacitors. Most people think they are meant to be installed and just used as-is but your supposed to charge them slowly prior to install and discharge them before removing them.
