💡 Why do mechanics swap raw vehicle juice to a regulated buck converter?
It works as a handy traffic cop that keeps your dash accessories from frying when the alternator dumps too much current or the starter draws heavy power. Builders love these setups because:
- locks down wobbly 12v banks to steady five volt feeds
- kills backfeed noise that messes with stereo signal clarity
- bypasses blown OEM fuses by handling short bursts automatically
