I've been wanting one of these for years and was finally able to purchase one. Comes with everything but a 9v battery. Very easy to use, my stereo system sounds absolutely amazing now that I've used this. No more fear of clipping and distortion that I couldn't pick up on myself. If you don't have one I highly recommend you get it.

This device is a must if you've spent a decent amount of cash on your audio system. It does exactly what it's suppose to do and it does it quick, easy and accurate. The only reason I give it 4 stars is that for $150 It would be nice if it also set crossovers accurately and maybe even had a volt and ohm meter because the way it is now after you set your gains, if you don't install for a living you will either store it away in a tool box or sell it at a discounted price. My system does sound awesome though with the peace of mind that no distortion is present.

This is a specialty tool that is used maybe a handful of times but is very handy when tuning your head unit and amplifier. Easy instructions, nice boot to prevent scratching, lightweight, and the leads are long enough. I purchased one of the first runs of the DD-1 s long time ago and my complaint was the RCA input on top of the unit didn't accept heavy duty RCA's. I'm happy to see they now include an RCA adapter to extend it for ease of use and adaptability. A must have in any car audio tool box 👍

Cannot believe that this device made so much difference in how my system sounds. It is the single best thing I have purchased for my audio system. The SMD-DD1 is the truth. For you people who say it don't work , you're full of shit. Steve Meade. Thank you for creating such a great product . This is what my system has been missing.

Very impressed with this unit! Takes all the guess work out and when your done with tuning, which is super fast, you know your set right and clipping or dirty sound isn’t going to make your system sound bad or cook some voice coils because of clipping. Comes with the CD to test with and harness. Awesome product and I would recommend this as a very good investment if your into car audio like we are! But it now...
