Mechman high output alternators · Authorized dealer
A TL with a wall of subwoofers in the trunk is a familiar sight at car audio meets, and it makes sense: a solid sedan body, a strong V6 and a trunk with room to build. What it needs next is current. This page lists each Acura TL high output alternator Mechman offers for 2004-2014 TL models with the 3.2L, 3.5L and 3.7L V6.
TL owners who build for SPL usually start with a sealed or ported enclosure, a high-power mono amp and a second battery mounted in the trunk. As the build grows, so does demand: a second amp, a bigger enclosure, more batteries. Each step raises the current the car pulls under heavy bass. An Acura TL high output alternator keeps the battery bank charged between tracks, instead of letting voltage sink lower with every song. Competition days make it harder: long demo sessions at idle, with the engine barely turning, put the whole load on the charging system and the batteries.
Fitment splits the TL into two ranges, and the finder above will steer you to the right one. The 2004-2008 3.2L and 3.5L use one Mechman series, and the 2009-2014 3.5L and 3.7L use another. Confirm yours before choosing an Acura TL high output alternator.
All three ratings are Mechman high output alternators from an authorized Mechman dealer.
A competition build needs heavy cable from front to back. Cable size matters as much as alternator size on a build this large. Start with a Big 3 and a power run from our amp wiring kits, then add trunk batteries from our lithium batteries or AGM batteries. The TL shares its units with Acura's flagship sedan, and RL owners have their own page. The Acura MDX page covers the SUV. Find more models in our Honda and Acura collection.
