I wouldn’t give 5 stars ‘because the dashboard lights still blink when i pull gain in the volumen. I figure if i put it may skip change the alternator of my Mit Montero Sport but i still need to do it in the future. But really it keeps loadded and stable current for my two amps what means better loudness.I’m so pleased with this purchase.. For real i recomend it. Good price and it makes his function very well.
