CES (Custom Electric Service, Inc.) is based in Northeast Ohio and claims to build "the Baddest High Output Alternators on the Planet." As the largest alternator supplier in their region with over 3,000 units in stock, CES offers slot wound, small case hairpin, and large case hairpin alternators ranging from 250 to 390 amps. Their premium XL models deliver 230-240 amps at idle—critical for car audio systems that demand constant current. With a 6-month no-questions-asked guarantee, lifetime warranty at parts cost, and custom powder coating options, CES has earned trust in the car audio community alongside brands like DC Power, Singer, and Excessive Amperage.
