With 500 farads of \u003cstrong\u003ehigh current capacitor\u003c\/strong\u003e reserve on tap, the SB500-51R delivers instant current to your amplifiers the moment transient demand spikes, preventing voltage sag before it can rob your system of dynamics. Stop headlight dimming, tighten up bass punch, and free your amplifiers to perform as designed.\u003c\/p\u003e\u003cp\u003eThe XS Power SB500-51R shines in front-engine import builds where factory engineers specified a Group 51R battery and aftermarket builders want an upgrade without relocating to the trunk.
