    Not the price of life

    Save your money and maybe buy a real Sundown amplifier! This was my first purchase from them. I’m not sure I buy from them again!

    SFB-1000D Amplifier

    Posted by Shawn Ashmore on Feb 04, 2022

    Great power out of this little guy. I have it pushing 1 SA Classic dual 2ohm wired to 1 ohm. I got JP to sign it, so im sure that added a little more bang for the buck lol

    Awesome AMP and Awesome Service

    Posted by Ken Mathews on Dec 08, 2021

    I want to say this AMP is well worth the investment. I am running it on 1 10" DVC 4 ohm Sundown Audio E series and man will this thing rock. I can't wait to add my other 10" and get the full potential out of this amp. As for the service what can I say they are outstanding had some problems on the set up of the AMP and they talked and helped me through everything. They are a great group of people and glad I ordered through this company.

    Shipping Sucks Not Very Reliable

    Posted by Ken Mathews on Dec 01, 2021

    I can't really review this product since I have been waiting 21 days and still have not received my amp. Not sure when or even if i will get this product. I had to file a claim and nothing is being done about this since it hasn't been 30 days. Once I get this or if I get this I will write about this until then watch out for the shipping, you don't know if you will get the product or not.
