Nice addition to upgrade the factory setup.

Quickly installed, just to get it up and running and verify it all works. At this time, essentially only have a Kicker S8L7 connected up powered by a Key 500.1 at 1ohm in a self-built 1cuft slot loaded enclosure. Input signal temporarily just coming from 1 of the rear mids. Have ran Crutchfield's 9 wire cabling x2 to run input from factory amp's front 4 channels and ran back to front speakers to be powered by a Kicker Key200.4. Rear mids will be powered from the PXE's built in power as they are just fill. I have a '20 Accord Sport, the factory amp definitely rolls off the low-end, was definitely missing having some and the factory setup is 8 speakers divided between 180W if I'm not mistaken. Removing the ANC and upgrading the cheap factory "speakers" definitely helped, but it was still quite lacking. Anyways, hopefully this week I will finish it up and have the Key200.4 actually in play. The plethora of options available from the PXE is very welcomed for either a novice or expert car audio enthusiast or non-enthusiast just looking for clean sound in the car environment.

Just an amazing DSP for SQ install

This is an amazing DSP that provides so much capability to setup and customize a system. It took some time to watch youtube and many calls Crutchfield support, but it is so powerful. I did the setup on a windows laptop but the phone app is also great to tweak the installed system. I had to install using line level outputs from a factory amp (2018 Volvo S90) but it gave me everything that I needed to make the install perfect. I can't say enough about this DSP-Amp. Highly recommended!

AWESOME

Where do I start about this thing? I upgraded from a Rockford Fosgate DSR1 to this and WOW, what a difference! The sound quality is better all the way around and the preamp voltage seems to be higher than what the DSR1 was even though the DSR1 is rated 8Vpp and this is rated 7.5Vpp. The tuning options are better, the sound quality is cleaner, clearer, richer, and more defined, and it has a Remote Commander module. It also has apps for both Android and iOS as well as PC. I'll get my only 2 gripes about it out of the way here before I get into the good stuff. One, the input and output terminals are on the top and bottom instead of the sides like all of Alpine's amps which makes wire routing a little more complex and it can only handle 7.5Vpp/4V Peak/2.625V RMS so you can't turn up a 4V head unit all the way anymore. The Remote Commander makes that not so much of an issue though because you can simply set the head unit at 2.63V RMS with a test tone and leave it, then control the volume with the Remote Commander which is its default mode. I like a volume knob better than the volume buttons on my iLX-207 anyway, so it's not much of an issue really, but it would be nice to get the full 4V into it. However, despite this, I actually had to adjust my amp gains DOWN with this unit. There are tuning options galore which I don't have enough room to list them all! GREAT processor. I do wish it had an Auto-EQ function though. HIGHLY recommended and that's coming from a professional!

Amazing DSP!

I didn't purchase this through Crutchfield but I feel compelled to leave a review to help others in making a good decision. I've been a car audio junky for 35 years building my own systems in numerous cars and some for friends. When it came time to upgrade my DSP I had my eyes on this unit. I did some research on this and other units and chose this one for many reasons. The biggest being the 8 powered channels. I wanted a good SQ system. I run a 3 way active system with a center channel and two 8" subs. This unit has made that happen. I've been an Alpine fan since day one. The build quality of this unit is superb. Nothing feels cheap to me. All of the controls you get with this is on par with most every unit under a grand. What sets it apart is the 8 powered channels and 12 total outputs. My tweeters and center channel are powered by this and the rest is powered by an Alpine PDR-V75. I haven't used the computer software to tune it yet but using the app to tune is simple and very convenient. The sound and clarity is incredible and imaging and staging are near perfect. Tuned with REW and the Harman House Curve and my system has come to life. The WRC makes adjusting the sub volume and recalling presets easy. My only complaint is when you recall a preset it's a bit slow in loading. About twice the length of time it took my old DSR1 to load. Also there's no upmixing of centers or surround speakers. All in all this unit holds its own with the best of the DSP's out there.
