    I love this digital signal processor/dsp I had a prv2.8x dsp tuned on it for 5-6 months , I tuned this one for around 1 hour -2 and sounds better and I don’t hear the noises people was saying it wouldn’t do even with my car running , I love this Dayton dsp-408 my wattage I was sending to my speakers with the prv wasn’t sending it all now I’m just dumb loud and clear 🤘I’d rate the prv a 5.5,(6)-10 and this dsp a 9-10-9.5 no joke changed my hole system up.. recommend this product 💯

    Great Value, unbeatable price

    Easy to configure, especially when paired with the bluetoooth accessory, very feature rich. Hard to beat the value of this product for the price. So far I am just using it as a line converter for my sub and it made a noticeable improvement to the sound quality of my bass.

    Software Defined Equalizer - Quality without excessive cost.

    If you don't get overwhelmed by the options and abilities a DSP like this affords you, you'll fall in Love. Just about everything you could ever ask for out of an EQ, is at your fingertips (USB-PC interface). Note: If you're having issues w/ the DSP cycling on/off and 'popping' (in a non-standard installation) you can easily bridge the +12V and REMOTE IN lines off its wiring harness, to keep the unit powered on as long as it's fed +12V power.

    Awesome product, awesome price

    Great product for the price. Only gave it 4 stars because the streaming Bluetooth isn't loud enough to use.

    Great feature set at a very good price.

    Good alternative to the more expensive miniDSP. Offers lots of features and is highly configurable. Shipped very quickly and is a must for audio enthusiasts.
