The strength of a vehicles electrical system is often overlooked when upgrading your cars stereo system with power amplifiers and additional speakers. The truth is - these additions can provide additional stress on your alternator or battery -resulting in diminished performance from the audio system. The simple addition of a T-Spec capacitor will improve electrical system performance by providing a buffer between the alternator and amplifier. Stored energy from your cars electrical system is held in the cap and quickly released to the amplifier when needed. T-Spec capacitors offer the lowest ESR in the business allowing the cap to charge and release its energy quicker.
