Full Range inputs only

RandomMemes from San Jose, CA on 5/12/2019

This amp cannot be used with a component system! Pioneer told me....it will NOT utilize the DSP function and only the EQ function with a multichannel component system. This will only work with a full range input.

Pros: The EQ is spot on cool. It made me want to put an old phone in my car as a digital EQ because it works good and looks cool.

Cons: DSP doesn't work for me. It is a glorified EQ without full range input.

Almost perfect

The vehicle i installed into was a 2005 Subaru Legacy and there is no option for an aftermarket head unit with the automatic climate control, The pioneer S1000A seemed like a good alternative which it is But it does not work with all android phones luckily I had my old iPhone laying around And I was able to use it to set up the DSP. Unfortunately I have to buy a Bluetooth adapter for me to be able to use my android phone other than that the product is really great made my stock speakers sound better. Hopefully this helps out the next guy look it up by this DSP

Pros: Excellent sound quality and easy to hook up with very little wiring

Cons: Does not work with all android devices

Way better sound from factory headunit!

Garrin from Springdale, AR on 2/25/2019

Great way to improve factory detuned systems, but headunit may be clearer sounding. It will though make your factory stereo play a must wider and more complete frequency range. Easy to set crossovers and each speakers level. It is a lot to learn as there are 4 modes that have distinct sounds and quirks. Volume cannot be controlled via factory knobs and buttons in certain modes. And the remote is a easy way around this, but the remote will not quickly run volume up and down it's a press, press, press kinda deal. My favorite part about this is having a DSP that can be mounted anywhere due to fairly small size and no need in being able to access it to make adjustments! Lastly I cannot attest the power it outputs to speakers as mine runs through a four channel amp. But wouldn't count on it rocking your world!

Pros: Easy adjustment after initial install.

Cons: Modes and different ways to operate through or around dsp completely! May just be learning curve.

Huge Difference for a low cost DSP

William Ortiz from Puerto Rico on 1/2/2019

Straight forward Integration. Sound has improved dramatically. Installed in my Nissan Altima SR with 6 speakers (Infinity tweeters, 5.25 doors, and 6x9 back). DSP fixed the poor signal delivered by the OEM Radio. Excellent customer service (Gil), fast delivery, and accurate description.

Pros: Fair price for DSP Sound Fidelity Very easy installation (for dummies) Works with 2 ohms speakers

Cons: USB cord Should be longer.
