Game Changing

The sound processor helped my system. Made it better. It instantly sounded cleaner and clearer. It’s possible using an EQ could give similar results but the unit is almost magic. I found using filters on my amps or head killes some of the dynamics so I end up turning them off but the crossover/filter in this must be exceptionally better. Using the sound app I made changes I may not have considered that improved clarity and removed distortion. My system is louder. The input output controls gave me more bass and helped balance two 15” MTX on different amps. The delay really moves the imaging and moves the subs when is crazy. It was fantastic until I started the car and I had alternator noises for the first time in this system. I moved the internal jumpers and removed it but there is some rumble way down and I had noise once trying to split to different amps. I since added a few filters. It’s hard to accept that mid bass is the downfall of most systems I have tried to build a system to optimize mid bass but the graphs are correct and the processor can dial everything in. Sonic had a nice price and usual there by Thursday shipping but more importantly had it available to consider. Looking for places to install equipment is tough but this worked out well and gives a professional look and sound.

Great product

A little costly but worth it if you want great sound

Best thing ever.

Everything I read about for high quality sound this does. I thought my system was clean and clear but this makes it better. Cuts distortion increases output adjusts for acoustic faults.

Audio Control

I'm trying to purchase a return label for order #24224933 and just feel like the web site is running me in circles. Can you please send a call tag.

Vocals sound like they're in a bucket, the remote bass knob does not function properly as stated in the user manual. you can't adjust the digital portion of unit or disable it. I'm very unsatisfied with this product "making good sound great" . I have a great sound system and this DQDX makes it sound terrible.

At this point no I would not recommend you! I was told by a women at your company, because I plugged it I can't return it. I'm 60 years old and have been into car audio for 45 years. I know how to plug in 12 RCA cables and a power and ground wire. This is nonsense, installation has nothing to do with my problem. The product does not work properly and even after getting her to issue R/A so your techs can look at it. it's very difficult to figure out how to purchase a shipping label from your web page.

I like to support smaller business, and honestly how the unit function does not reflect on you. but your return policy is not good. I guess I should have used Amazon

there's my review
