2011 Toyota Camry Alternator Upgrade — 2.5L Four-Cylinder
The 2010-2011 Toyota Camry 2.5L leaves the factory with roughly 100-130 amps of alternator output. Factory electrical load on this generation already runs 80-110 amps once you account for climate control, lighting and accessories, which leaves very little headroom for anything you add. This direct-fit JS Alternators unit drops 250 amps into the stock location using the factory mounting and the factory plug.

Why the stock Camry alternator runs out of room
A 500-watt RMS audio system pulls roughly 50 amps on top of the vehicle's existing load. On a 100-130 amp alternator that puts the charging system at or past capacity any time the bass hits, which is where headlight dimming and voltage sag come from. It is a supply problem, not a wiring problem. Background reading: our Toyota Camry alternator guide and the alternator sizing guide.
