    I haven’t installed the item yet, but the product came new in box. The seller gave great value and it looks great. The quality of customer service is excellent. They provided prompt feedback and follow up to my inquiries. Seller went out of their way to try to help find where my item was. FedEx dropped the ball and held my item for 2 weeks in one location. Awesome commitment to customer service.

    Kenwood 4710 head unit w/ Kenwood cmos back-up camera. Brand new in original factory seal packaging exactly as described. Shipping was fast, and I’m happy with zero complaints. This is a great deal at this price point for a solid midrange head unit that has a lot of features for the money, w/ a matching backup camera! Would highly recommend this product and the seller! 10/10 👍

    A powerhouse amplifier!

    What a great little amplifier. Running @ 2ohms for all channels powering CDT Audio 2ohm mids and tweets. So clean and so loud! Running a RF Punch 500x2 on the CDT Audio midbass @ 2ohms as well. The combo is unbelievable in this active setup.

    High quality, great power and reliability.

    Excellent build quality, amazing sound. Good for full range or subwoofers. Stable to 2 ohms. Very happy with this amp. Rockford is always impressive for the price and I'd always recommend getting Punch over Prime series even if it means getting a lower wattage amp.

    Awesome amp!!

    The name says it all Rockford Fosgate need I say anymore. I bought this one to replace a 600x5 prime amp that has a little problem with it, This amp is really easy to setup and install. It's loud and Crystal clear at full volume you can hear the mids and the highs very crisp and clear. This has to be hands down one of the best amps I have ever bought so far so good I really love it and would recommend this amp to anyone who is looking for a great product like this one. Rockford Fosgate punch products are still top of the line. This amp packs a lot of very useable power and the butter worth cross over is a great feature for the head units that don't have one and the tune ability are set it and forget it with a very useful setup CD that comes with it.
