SMD Distortion Detector DD-1 | AMPLIFIER TUNING TOOL

The only way IMO to properly adjust and set up your system, great deal for the price and piece of mind!

If you have thousands of dollars into your system, you might as well spend a little bit more to help get your settings right!! Originally, I set my mono by ear.. But when I used the DD-1, I was able to get even more out of the amp. Very easy to use and has instructions too

Love my smd products very easy to use and know your setting the grains the right way

It works great has my system sounding better than ever before. Jp has the fastest shipping and prices he’s killing it!!! This is by far the best place to buy audio equipment!!

Easy to use

I bought this tool to set my amplifier gains. It is super easy to use and I have to say my system sounds so much better. I can play it way louder and not have to worry about sending a bad signal threw my speakers/subs

Great product and came with very detailed instructions that made it super easy to use. Have my head unit and amps tuned perfectly now and they sound amazing.

Awesome product!! Highly recommend it to anyone who cares about their equipment!! Im really good with doing this by ear but can’t beat dead on accuracy of this little device! Turns out I had a little more volume left on the head Unit and the sub amp.. As always super fast service and shipping!

This is a must for everyone with serious audio on there cars so u dont end up damaging ur audio it's a must have

To be absolutely honest this thing feels like the thinnest cheapest piece of plastic I have held for 100+$ now that being said it works flawlessly and everything was perfect. Now my thoughts is to why it feels so cheap is it’s lightweight enough to hold as long as it takes to adjust the gains. All in all very satisfied with it does exactly what it was designed to do.
