Shout out to JS alternators there the only ones who made a high output for my model car. Without it there’s no way I could run my current system on my stock alternator.

Received two Alternators from JS and don't regret one moment of it. They have been great and when playing my system as hard as I can the Alternators have been able to keep up with all the power needed!
