PRV AUDIOCar Audio DSP 2.8X Digital Crossover and Equalizer 8 Channel Full Digital Signal Audio Processor DSP with Sequencer Remote Relay

So I've been on the fence about one of these for a little while now. I wanted to do something with my system, but not anymore equipment upgrades. So I decided to make this purchase. I didn't want to spend six or $700 on a helix so I went with this. It doesn't have all the bells and whistles, but perfect for what I was looking for. At first I wasn't a full believer. Just couldn't seem to get the sub to sound much better than it did before. Well, after some patience and some tweaking, you can believe I'm a full believer now! WOW! It seems to me, and I know this doesn't really make much sense, but it almost seems like this needs some breaking in. It just seems to sound better all the time. I'm doing everything by myself and by ear. I'm not investing in mics and all that other stuff, just not that important to me. Been playing around with the time alignment and oh my God it sounds incredible. Still obviously in the tuning mode but this is proving to be very well worth the money paid. I'm running one Alpine dual voice coil sub at 1 ohm and I cannot believe I'm getting this sound out of one 12" sub. Any problems I'll be back with an update. Oh, and also, no engine noise.Update: 10 months later no probs. Upgraded some equipment and moved this to my glove box. Gets a bit warm in hot weather but no heat issues with unit. I just open the glove box for air circulation. I think I would like something better, but this works and I don't wanna spend so much time learning another one. It's $30 less than when I bought it so I highly recommend this if you're looking for something basic, effective, and affordable.

Exactly what I needed. No issues

I just want to first say this is an amazing value for the money. After a few days of playing around with it I was able to improve the SQ of my car 10 fold.I’ve never done any car electrical wiring but I was able to install this with ease, especially because I already had an amp installed. I took the 8 gauge power wire off the amp, connected it to a power distribution bus bar, then ran power back to the amp and to a fuse block, and from the fuse block to the DSP.I went with this over the Dayton offering mainly because this offers a higher voltage output and I wanted a stronger cleaner signal over greater tuning capabilities, also the Dayton seems to be hit or miss on adding noise based on the reviews.With that said there are some quirks. I’ve only have had this unit for a week and I’ve already had the menu go dead on me while making adjustments. Turned off my car and it came right back, but is concerning with only having it going for a few days.Also I don’t think the pink noise generator is accurate pink noise. I tried tuning based on the device’s built in pink noise and gave myself quite the headache trying to figure out how the sq was getting worse despite achieving my ideal frequency curve. Played a different pink noise sample and got it tuned near perfection in less than 15 min.With near perfect being said…It does only have 13 bands and only able to set a single parametric eq. Therefore you can only achieve so much. If close enough is good enough for you, I’d go ahead and buy based on the cost to performance ratio.Overall if you’re wanting a DSP that will get your car audio tuned to 80-90% of perfect this is a must buy for $150. I can now play almost crystal clear music to the point where signal distortion clipping occurs. I’m extremely happy with the performance and highly recommend!Edit: 4-27-22After further diving into the world of sound engineering, I’ve been able to even further increase the quality of sound from my setup because of this device. I still think it’s only 4 stars, because it lacks detailed customization, and quality of life features. However if you know or are willing to learn the nuances of sound frequencies this thing is incredible for the money. Biggest requests would be more than just a single parametric eq channel and a wireless ability to change between saved eq settings. I’ve essentially spent a good 40hrs tweaking everything to fit as many music styles and ages as possible, because switching genres or listening to music made for radio can sound horrible if you tune only using pink noise, and without an option to changes custom presets you’re f***** if you have an eclectic taste in music. After spending 40hrs tuning, I’m about to spend another 40hrs learning how to hack this thing to enable this feature 😅

Works great with the Mono-block amp setup that I am working on. Using the DSP to split the frequencies between tweet, mid, and woofer.I have had no problems using this unit

This item eliminates 2 problems, first the noise pop noise when you turn on or off the radio, second, eliminates the use of a pream. This unit controls all your system !!!! Highly reccomended!!!!

I enjoy the first one I ordered. It works well and sounds good. I decided to order a second. It showed up damaged. I returned it and the seller charged me a 20% restocking fee even though they sent a damaged product. It was damaged at their facility because the shipping box was fine and so was the product box. The connector strip for the remote signal input and outputs was shoved into the metal housing and the screws broken off. Probably won't buy another.
