Authorized dealer · Car Audio Bargain
Strong bass starts with stable voltage, and this car audio batteries and power department brings together the parts that store and replenish it. Shop XS Power AGM and lithium batteries in 12V, 14V and 16V, Sundown Powersports batteries and the SA150-975L super capacitor battery from Sundown Audio, XS Power SuperBANK ultracapacitors, and IntelliCHARGER and IntelliSUPPLY units for charging and bench power.
Amplifiers turn electrical power into sound, and when supply voltage sags on heavy notes, output falls and some amplifiers may even go into protection. A healthy system rests on three pieces: a charging source that keeps up, storage that delivers current on demand, and wiring that carries it without excessive loss. Car audio batteries and power gear in this department handle storage and charging, while heavy 1/0 AWG power wire and proper fusing complete the path.
AGM batteries are sealed, work well on a standard charging system and are a common pick for daily drivers, from XS Power D-Series starting batteries to XP-Series reserve batteries, S-Series racing models, V-Series vintage batteries and powersports units. Lithium batteries save weight and hold voltage well under load; XS Power offers lithium titanate in the TITAN8 and XV-Series lines, Li-Series racing batteries and xMax LiFePO4. Any lithium battery needs a charging voltage and charger profile made for its chemistry.
Nearly every vehicle runs 12V, so most builds should start there. 14V and 16V batteries belong in systems where the alternator or charger is set to that voltage and every amplifier and accessory on the circuit is rated for it. Builders commonly separate a higher-voltage bank from the vehicle's 12V circuit with an isolator or a dedicated charging setup.
Think of an ultracapacitor as a sprinter and a battery as a distance runner. XS Power SuperBANK modules answer sharp bass transients in a fraction of a second, while the battery supplies energy for the whole song, so systems that use them pair them with batteries.
An alternator recharges the bank while driving, but demos, competitions and storage call for a dedicated charger. The IntelliCHARGER range in our chargers collection includes AGM and lithium versions for 12V, 14V and 16V batteries, and IntelliSUPPLY units provide steady power for tuning and display use. As your system grows, plan the battery bank and charging together, then match amplifiers to what your electrical system can sustain.
