Rockford Fosgate DSR1 8-Channel Interactive Signal Processor w/Integrated iDatalink Maestro Module

Installation was a breeze. The unit requires three updates/programming. If you follow the steps in the order given in the instructions, it works great. Miss one step and you'll have problems. But easy to remedy by going back and follow the steps.The DSR1 has outputs for 8 channels. 4 are standard stereo outputs, one that is labeled "spare" channel and then the subwoofer outputs. I chose to use the iDataLink Maestro cable and features which allows for retaining all the factory controls.The systems, once tuned and amps set with proper gain sounds AMAZING! The Perfect Tunes software for the EQ and Crossovers is a bit overwhelming to learn to use. This is not a standard EQ, but a 31 channel EQ. There is a setting for a standard 6 bar EQ, but since I chose the Maestro features I can't access that in Perfect Tunes as it relies on the factory head unit's EQ settings which in my case is a 3 bar EQ...Bass, Mid and Treble. So what I did is set my speakers up to crossover settings with highs going to dash, mids going to front doors and bass going to rear doors. This allows me to use the trim levels to control what you normally control with an EQ. Between that and the 3 bar EQ on the HU I get a lot of control. If I need more control I go into the 31 bar EQ.This setup is not user intuitive. It will require a bit of a learning curve unless you've worked in audio before. It is pretty high level audiophile stuff. Read up on Rockford Fosgate 3.sixty as it has basically the same settings as the Perfect Tunes app.Update:9/24/2020-while making some adjustments to crossovers today the DSR1 locked up. My volume control did not affect volume of music coming out of speakers, although the display showed the volume control change it had no effect on the actual music coming out of the speakers. I turned off the vehicle and let it sit for a few minutes and then turned vehicle back on. Now I have no sound coming out of my speakers. Everything looks fine on the display but no sound. Had to remove the radio console from the dash since I mounted the DSR1 behind the radio, then unplug the harness from the DSR1 to get it to power down. Plugged it back in and everything is working again. So warning to others...mount this unit somewhere you can get to easily so you don't have to tear into your dash every time it needs a reboot. Of course that requires the purchase of more cables to extend it to where you can mount it. I'm about to go shopping now for the cable extensions. Hopefully its plug and ply. I'm capable of making my own cable so I may go that route if I can't find a premed extension so I can relocate the DSR1.

I absolutely love the product. Getting it setup wasn’t to hard and when it was installed it worked exactly like it was supposed to. The Rockford 300.4 amp was making the 2 component sets I installed sing loud and clear. The product showed up a day early and was well packaged. I’m only giving 3* for ease of install because of the proframming the unit, once you get that done the physical installation is very straight forward.

Installed my self to complete the setup with a 5-channel amp and the factory radio (used without the maestro) and it is really a good product, now the sound is clear and the bass is better. The app is a little hard to follow at the begining but after some minutes you get used to it. I would recommend this product.

For the price this has to be the most affordable quality DSP on the market. 4 channels of input and 8 channels of output was perfect for my needs. Independent volume, time alignment, crossover, and equalization for each individual channel it’s amazing. You can tailor each part of your system just the way you like. Adjustments are at your fingertips with the Perfect Tune app. I also have the PLC2 Wired level control which I assigned as a master volume. If you want to bring your sound system to life and have customization abilities a DSP is a must have and this is priced very well. Can’t go wrong with Rockford either. Once you get this don’t forget to update it. The update process is not the most user friendly but Five Star Car Stereo has excellent YouTube tutorials about this DSP and a dedicated YouTube video for the update process.

Google terrible Bluetooth connectivity with certain devices they have an updated the software years we're gonna give it another try but I think I'll be returning this and getting a diamond audio you go to the Rockford Fosgate website which hasn't been updated in years to download all the software you go to the web link/the mall to the universal close that program correct auto operations open up the rocket updater app, but instead of it being . Come on Amazon is a staff offering, third-party distributors hold them accountable. This DSP did come in perfect shape however, you just can't update the software.

Programming the device online was a piece of cake. Installing it next to my amp was easy enough. There were some hiccups with the remote wire and multiple amps but I dialed everything in after some trial and error. Surprisingly not a ton of resources online to go to for help. Love being able to keep my stock head unit. Also, no issue buying an open box product. Saved some $.
