Pontiac Bonneville High Output Alternators

The Bonneville is a full-size Pontiac with a long wheelbase, a 3.8L V6 and a trunk big enough for a serious enclosure, which makes it a natural highway cruiser for audio fans. This Pontiac Bonneville high output alternator collection lists two Mechman units for 2000-2005 3.8L cars, at 240 Amp and 320 Amp.

Highway Cruiser, Trunk-Sized Ambitions

Long, quiet highway miles are where a Bonneville shines, and a good sound system makes them better. The trunk has room for a large ported box, and the wide cabin gives door speakers space to breathe. What the car may lack after two decades is a charging system ready for a pair of amplifiers. A Pontiac Bonneville high output alternator supplies the current a bigger system draws and keeps voltage stable on long night drives with the headlights, climate control and audio all running.

The 240 Amp unit suits a single amplifier with a subwoofer and component speakers. The 320 Amp unit is the step for multiple amplifiers or a build with added lighting. Both are Mechman high output alternators from the early front-drive GM V6 series that also appears on the Buick Rendezvous and Oldsmobile Cutlass pages.

The listing covers the 3.8L V6 in 2000-2005 models, so confirm your year and engine in the vehicle finder above the products before ordering. Fresh charging components from our alternator harnesses and regulators collection are worth a look on an older car, and other models are on the Pontiac alternators page.
