I purchased this amp with the very ambitious idea of trying to power a JL 10W7 with something in the $150-$200 price range. Although this was a massive gamble, I decided to look into this amp based on previous reviews that I had read and some good word of mouth with the Hifonics name - a brand that I had admittedly never come across in person. So with cautious optimism, I held my breath and purchased this amp, fully aware of where my expectations need be.
This amp is a true wolf in sheep's clothing. This thing pushes my 10W7 so hard, clear and accurately that it almost seems at times they were meant to go together. I've owned the JL 500/1 before (previously pushing 2 10W3V2s - a setup that I begrudingly had to sell years ago) and the Hifonics 1500D/10W7 combo is noticeably better than the previously mentioned setup - both in SQ and SPL. This amp is rated at 500W @ 4ohms, and 1000W @ 2ohms. However, rest assured that the amp runs perfectly at 3ohms, the output being around 700-750 watts.
If you're on the fence about this amp, let this review be the tipping point. There's a saying in life that's proven itself time and time again: if something seems too good to be true, it probably is. This amp is one of those rare exceptions. You will not be disappointed.
