Authorized dealer · Car Audio Bargain
Car audio systems that pull serious current depend on the electrical side, and XS Power covers it with D series AGM batteries in common group sizes, S series racing batteries for starting duty, PSX powersports batteries, Li-S and PWR-S lithium batteries, SuperBank ultracapacitor modules and IntelliCharger chargers.
As an authorized dealer, Car Audio Bargain ships these from its warehouse in Newton, North Carolina.
The D series, including the D3478 Group 78 and D375, is the usual pick for car audio, built to deliver current repeatedly while the system plays. The S series, such as the S975 and S375 AGM racing batteries, focuses on starting duty and racing applications. For motorcycles, ATVs and UTVs, PSX models like the PSX14L, PSX14Q and PSX20Q come in powersports group sizes.
AGM batteries are sealed, tolerate vibration and can be mounted in more locations than flooded batteries, and they work with conventional charging systems. Lithium options such as Li-S and PWR-S save significant weight and hold voltage higher under load, but they need a charging system and charger set up for lithium. Never mix chemistries in the same bank. When adding a second battery, match the model and age of the first where possible so both charge and discharge evenly.
Check group size and terminal layout against your battery tray, or plan a rear bank close to your amplifiers with heavy gauge cable and a fuse at each end of any long run between batteries. Power wire and wiring kits from the brand are listed here as well.
SuperBank modules such as the SB430-16, SB1050-31, SB1260-27, SB1260-31 and SB1500-75 store energy in ultracapacitor cells and release it in fast bursts, helping steady voltage on heavy bass notes. They supplement a battery rather than replace it, and they make the most difference on a system that already has adequate battery capacity and charging. Browse sizes in SuperBank ultra capacitors.
A battery is only as good as its charge. XS Power IntelliCharger units keep a system topped up between drives and after long demo sessions with the engine off. Match the charger to your battery chemistry and bank size. If voltage still sags with the engine running, the bottleneck is usually the charging system, and a high output unit from our alternators collection addresses that directly.
