The pyle audio capacitor is specially designed for your daily usage and has all useful features. It's got all you need to make sure your system sounds awesome and stays safe. Once your main battery is charged, it'll charge up the capacitor and you'll be set. The included proprietary bolt/terminal system is very weak but also quite easily replaced.

The digital volt gauge works good and looks cool in blue. It stays on all night long. The voltage readout is nice and is a nice pairing to the sound system. It is great for a 1 or 2 amp system. The bass sounds much better now that the power is available.

Why We Like This:

Keeps juice flowing to both amps
Awesome replacement for a dead capacitor
Works well and is very reasonably priced

Best For systems: recoil Audio Capacitor

Best For stereo: stinger Audio Capacitor

Buy on Amazon

Best part: stinger audio capacitor costs comparatively low and it is available to ship in 24 hours. These screw down connectors are way better than the cylinder design. This cap has rock solid build quality, lightning fast discharge, holds it power very well and is adjustable in its output voltage for a massive increase in the voltage stability and stiffening power high current systems need. It is hooked in parallel with your power source (batterie(s) / alternator) - it's supposed to help the power system stability. This allows the amp to run at no less than 14v and remain exceptionally stable in terms of power reserve.

These capacitor loads are a buffer, a relatively large one versus the massive peaks of current demand from large amplifiers and dynamic power comsumption. The charging bulb is incredibly small, comes in a zip lock bag and is very easy to lose. It will stiffen 5000 watts additionally it is always best to allow for headroom. This is a very high quality capacitor, not to mention it looks nice and sleek on any install.
