Customer Testimonial

Absolutly fantastic over the phone transaction with Brenden H. Totally hooked me up. The experiance was so good if fact, I'm going to link Sonic Electronix to the the Mazda blog that I am a part of, as the guys are always looking for honest, clean referals for audio components for their cars.

When heavy bass notes in your music hit, the current demand on your system greatly increases and could cause voltage drops. This stiffening capacitor acts as a power reservoir, instantaneously supplying added power to keep your system playing strong.

I got this capacitor for christmas and have it running two rockford fosgate p3d2 2ohm subs and I love it. The light behind the digits is bright, but kind of adds to it. I have actually got several compliments on the way it looks as well.

It's built very solid and does its job like a champ. I enjoy many of Boss's products and this is one of the most valuable products you can install in your car.

At first it was working fine then i notice my lights started dimming after about 2 months. This Cap actually blew up like a bomb in my Jeep and my car wasnt even turned on. I wouldnt recommend this product.

I have a 3500 watt RMS system and this Cap handles the power draw with ease. I've notice substantially less dimming from my head lights and more powerful sub-woofers hits.
