Car Audio Batteries, Alternators, Wiring, and Electrical Support
Shop batteries, high-output alternators, power supplies, battery mounts, power cable, fuse protection, distribution, grounding, and related electrical products for daily and high-output 12-volt systems.
Electrical components must be selected as a complete circuit. Match battery chemistry and voltage requirements to the vehicle's charging strategy; size cable and fuses for actual current and circuit length; confirm a low-resistance ground path; and evaluate alternator output, battery reserve, accessory loads, and expected duty cycle.
A battery or alternator upgrade cannot correct a clipped signal, incorrect amplifier load, poor enclosure, weak speaker mounting, unsafe gain structure, or inadequate wiring. SMS can supply products only or plan and install an approved complete electrical system.
