CAP8

Wired this into my car audio setup and the difference is obvious — bass hits harder and the lights don't dim on heavy kicks anymore. The low ESR really shows, it barely warms up even after long sessions. The reverse polarity alarm saved me once already when I hooked it up backwards.

The 3-digit LED is stupidly bright, which makes checking voltage at a glance actually easy instead of guessing with a multimeter. Reverse polarity warning already saved me once when I wired it backwards by accident. Held steady at 14.4V with no dimming on hard hits.

Hooked this up to my sub amp and the difference in punch is obvious right away. That 8 farad bank keeps voltage steady even on heavy bass hits, and the E.S.R under 0.004Ω is no joke. The super bright LED readout is a nice bonus for keeping an eye on things.
