Zero floor noise. Wow I amazed with the quality for the price. *by D***Y on October 31, 2023* Yes so far so good. Not much support on the product and not sure if there is a mobile app. No way to contact the seller. I am coming from a Rockford Fosgate 3Sixty.3 for reference. I got the dreaded Soild red light and nobody can repair it and I needed something quick and cheap so I did not have to go weeks with a radio. The Seventour is not as intuitive as the 3Sixty.3 but the 1st thing I notice is the floor noise is much lower. I did not change anything in my system just a DSP swap and not more hiss and random noise in my right rear speaker complete silence when volume is off. I just wish the remote was more compact and simplistic like the Rockford 3Sixty.3. It has been install for 3 days now and I am happy so fare. Will tune with a RTA in the next few weeks and see how it performs. Back set up with cross over point and time delay right now. Zero equalization right now and I hate to say it but sound better that my 3Sixty.3. I am using it as a pure DSP connected tobacco factory head unit with a RF Punch 1000x5D.I will post another review in a few weeks11/10/20232nd Review after having it install for more than a week. Originally I stated not much support for the product. I take that back. Eventhough they do not currently have a website, I have emailed several questions and the responded in less the 12 hours. During my time at SEMA 2023 I saw several other companies selling their DSP's for more and some for a lot more and quality was not as good as the Seventour P48E. This is one of the lowest price legitimate DSP's on the market and it is not is one those little plastic cases like some of the well know brands that offer similar or less features. If you are in market a DSP's get this one before the word gets out and the prices go up. I would not be surprised to see it being re-branded and sold under a different name for more money next year. I have had time to start find tuning my system and I still impressed with the sound quality, but the best thing is no noise added to the system. ### ⭐ Send it back *by J***A on July 31, 2025* Definitely couldn't get it to work horrible install my work paperwork ### ⭐⭐⭐⭐⭐ Awesome DSP! *by V***H on October 18, 2024* To have been looking for an affordable and decent DSP for a while and I came across this one it amazing, produce great quality sound with the ability to tune your system to exact frequencies with out additional equipment. It also come with some preset tuning which you can work from which is a plus. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/711361791-p48e-dsp-car-audio-digital-signal-processor-car-equalizer-built](https://www.desertcart.uy/products/711361791-p48e-dsp-car-audio-digital-signal-processor-car-equalizer-built) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-08-01*
