    Absolutely incredible design, definitely a must have for any one trying to power multiple sources. It has an amazing look compared to a regular relay. Very professional company and very knowledgeable. I will be definitely sending people there way

    Love the product, pictures do not do it justice. It came with a extra fuse and the Allen keys needed. Packed well. The instruction book was clear and has detailed information. Extremely happy.

    Excellent product, very well made and very handy for running multiple higher current circuits. Much cleaner and easier than using tons of relays and fuses, ect.

    If you’re looking at buying this, I would 100% recommend it between the build quality and how intuitive it is!

    I met these guys at Slam this year and saw the products they were selling at a booth. I got a few items and was surprised what they were selling them for.
    Now this relay box is amazing. I’m going to buy more because this is a awesome product well crafted and super nice to look at.
    I suggest everyone to buy one before the price goes up because what they sell these things for are a steal.

    As a business owner, customer service is extremely important along with quality products. Sparked is at the top of the realm in both departments. Thanks for all you do.

    I purchased this unit for an old school car audio build for my 2016 4Runner. The installation shop that did the work was amazed by the looks and functionality of this unit. I paired it with the single DIN panel and interconnecting wires for ease of use and installation. This box allowed the versatility I was looking for with the ability to turn on/off rear stage amp, sub amp, amp rack lights, and fog lights. Very nice piece and highly recommended to anyone looking for next level installation. I will be purchasing another one form my car audio test bench soon.
