Alpine PXE-0850X

Alpine PXE-0850X sounds great and was a breeze to set up and tune.

I was initially surprised by how small this unit was. Installation under the passenger seat of my Cherokee was very doable. The documentation had plenty of examples for how to hook everything up and the RCA outs made wiring up everything a piece of cake. I actually don't own a laptop of any sort so I LOVE the fact that I could set this up via Bluetooth in the app. My set up has three 3.5 speakers up front along with two tweeters in my rear pillars as active from the DSP with four 6x9s non-active going into their own amp. Making small EQ adjustments for taste after an shop-done RTA tuning was very simple and fast.

Getting connected to the device was a bit harder than it should have been. Upon first use, I had to initiate a connection 6 or 7 times before it actually took. After that though, it's connected every single time with no issues. For being as expensive as it was, I do think that it should be able to push out a bit more than 25w though.

Love this DSP

Great sound, tonal options and it can be adjusted from a smartphone! The app is easy to navigate and laid out pretty straightforward. The only downside is inability to mount the remote control somewhere neatly.

AWESOME processor

Where do I start? I replaced a Rockford Fosgate DSR1 with this and it’s INCREDIBLE. Let me get my couple gripes out of the way before I get into the good stuff. The inputs and outputs are on the top and bottom instead of the sides like the amps are, so it complicates cable management, it doesn’t handle a true 4V preamp voltage, and it doesn’t have an AutoEQ. The voltage issue is EASILY overcome with the Remote Commander though because it defaults to volume control and you can just set the head unit to 2.63V RMS with a test tone and leave it. It has tuning options GALORE, the sound quality is FAR superior to the DSR1 because it’s richer, more powerful, cleaner, and crisper. It INCLUDES the Remote Commander module and Bluetooth module where other high end DSP’s require those items to be purchased separately adding more cost to an already more expensive processor that really doesn’t have many more capabilities. I love this PXE-0850X despite my few gripes. Coming from a professional installer, I HIGHLY recommend this unit for both cost effectivity and quality. The chassis on it is actually made of cast aluminum rather than plastic like some other inferior units are. I can’t say enough good things about it actually. DSP technology has become so inexpensive, your system can’t afford to be WITHOUT it! Get either this or a PXE-X09 and be done.

Great Price and shipped fast

I was shopping for a DSP for a while. I was lucky to have gotten this unit on sale. But was surprised how fast it got here.
