I got my son into car audio. And as you would suspect more bass the better for this kid. His budget is limited so a cap was a good way to stop the lights from dimming until he can afford to build his system up to handle the bass he likes. The cap seems to do it's job.

I have this running two amps, 1 4channel, and a mono block, and lights still slightly dim, but I'm at 1900 watts, so I should have gone for the 3 fared cap, but I do recommend this a friend, and he got one running his Alpine MRP500, so this is a very good bargin cap! Color scheme is extremely annoying though, couldn't have been anymore cheesey looking, the only thing I want to see is the voltage meter, and the blue led is so bright, I have been pulled over for cops thinking I have a light bar!!
Instructions are very bad, watch sonics videos to understand what you need to do
Thanks sonic!!

I bought this cap a few months ago. it works great. i was able to hook it up and charge it without a problem. the mounting brackets work great too, just make sure you use self tapping mounts. it looks and preforms great. i would def. recommend this to anyone who needs a cap. it got rid of all my light dimming problems as well. the price is a steal for the quality of this item

I bought the BOSS to help with peak loads and to save my alternator. I was experiencing headlight dimming when my subs hit hard and already burned up an alternator. The BOSS cured the problem. Now I can boost the gain on my amp which I couldn’t do before and my lights never dim. I have owned the BOSS for almost a year, it was easy to set up and works as advertised. I would recommend the BOSS as an inexpensive alternative to upgrading your alternator.

Customer Testimonial

Sonic had exactly what I needed for $100 after shipping. After getting my new wiring, I was so excited that I not only got what I wanted, but also for way cheaper. Sonic returned all my messages with in 24 hours. You can either do it right or do it twice. Thanks Sonic for helping me do it right.
