Review: Quality DSp - Good quality, well worth the money. Helped me enhance my PRV speakers even more. And being that I'm not a professional so I don't even think I have the adjustments correct to get the full potential of the speakers and they still sound great. So many wonderful features to play with. One of my favorites is being able to turn amps on in sequence. Functions very well, very easy to install, and like I said, I'm a non professional.
Review: Patience required - 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.

### ⭐⭐⭐⭐⭐ 2 times the charm!
*by P***E on October 18, 2025*

Ordered and installed needed a replacement because setting would not save and load automatically. Replacement arrived super fast and is working great. Definitely a game changer from traditional crossover setups with multiple amps! Fine tunes each channel to your liking
