EDIT*** 8.8.2022 update - Still looks and works fantastically!!! NO REGRETS!!! Quality built! Recommended! Used to help power my Pioneer D9705 amp.

Be cautious when working on your car though, because your electrial system will still have power in it for a few seconds after disconnecting the main battery, as the capacitor is like a small battery (this was how I che ked the capacitors ability to charge and discharge itself).
