Best product I've purchased this year so far. I was not sure about it as it's a brand new item with no reviews. However, I know boss brand as I purchased their double din units before and they worked great. I would say it surpassed my expections by really a lot. The space in my truck is limited but this one fits right in. The sub hits perfectly at 600W. It was quite easy to install as everything is built in together.

Very compact, highly adjustable built in amp. Was expecting medium performance & sound for the price, but was delightfully impressed with the actual sound and performance after installation. This thing WILL shake all your mirrors with ease, I set my gain and source output only to 50% output and this thing still rocks!
