PAC ROEMINS-2 System Interface Kit to Replace Factory Radio and Integrate Factory Amplifiers for 1995-2002 Nissan Vehicles with Bose Audio Systems,Black

I previously purchased the SOEM-4 to connect an aftermarket receiver to the exisiting factory Rockford-Fosgate system in a 2010 Nissan Frontier Crew Cab. The head unit only produced 2.5V of pre-amp voltage, so the best course of action instead of using the Metra 70-7551 harness was to use the 70-7550 harness along with a LOC to use the high level speaker outputs of the head unit into the factory Rockford Fosgate amp. Reviews for the OEM-2 adapter were great, however -- that product appears to have been discontinued, and anyone ordering one seems to get an automatic "upgrade" to the SOEM-4. Take a look at the reviews on the SOEM-4, and you will see that you're in for a disappointment. I initially installed that unit, and it was huge - it did the job, but created a constant hiss whenever it came on with no music playing. Plus, the amount of wires behind the dash with the 70-7550 and the SOEM-4 were just out of control. Quality of the SOEM-4 is terrible as well, the cover doesn't stay on, people reported the pot knobs would just break off, solder joints would break from speed bumps.. Out of curiosity, I figured I would try to locate the ROEM-NIS2, which uses the same vehicle interface as the Metra 70-7550 built in to it. Based on the reviews here, the ROEM-NIS2 seemed to make everyone happy.. Plus, the OEM-1 unit is a bit more compact, and much more solidly built. The most important part is that the audio quality of the OEM-1 excels, with no noise whatsoever. It took me 15 mins to swap out the SOEM-4 and 70-7550 harness for the ROEM-NIS2 and now I am finally happy with the results. Even though the application guide doesn't list many vehicles, and specifies it is for Nissan vehicles with Bose, it performs the same actions for Nissan vehicles with the Rockford Fosgate "premium" audio system as well (chances are, the systems are probably both manufactured by the same company, with Nissan licensing the Bose or RF name only). This was a great product, made well, and performs great. ALSO - one thing of note.. Another reviewer commented that you had to connect the two positives for high/low together for it to work properly.. I contacted PAC, and was informed that this was incorrect info -- if you have 4 speaker outputs with 8 wires, you will use just the HIGH (+) leads. The LOW (+) leads get taped off and not used. The only instance you would use the LOW (+) leads would be if you were utilizing the unit to connect low-level pre-amp outputs that had the RCA plugs stripped off.

Work with my G35 Coupe 06 Bose System. I did it myself, and I learned that by Google and Youtube. LOL. I guess I was lucky, did all the wires and one-time got it to work. PURE LUCK, I think. Here are my list that I installed in my G35. 1. Pioneer AVH-X4800BS (about half of an inch short vertically, perfect to store USB and AUX cables LOL.) Not a perfect fit on the JDM Double Din. 2. INFINITI G35 COUPE/SEDAN 2005-2007 JDM DOUBLE DIN KIT W/NAV DUAL A/C 3. PAC ROEM-NIS2 System Interface Kit to Replace Factory Radio and Integrate Factory Amplifiers for 1995-2002 Nissan Vehicles with Bose Audio Systems (For the Double Din) 1995-2002, but it worked in my G35 06. The colors on the car will not look the same, I was scared at first, but I checked the car harness diagram, and it's a perfect match. 4. Metra 40-NI10 Nissan Antenna Adapter (For the Radio AM/FM) 5. MicroBypass ALL AVH-X Video In Motion Interface for Select Pioneer Receivers (For Bluetooth and work while driving). 6. Metra Axxess ASWC-1 Universal Steering Wheel Control Interface (For the Steering Wheel) 7. Metra 70-1771 Radio Wiring Harness for Ford/Lincoln/Mazda 1998-Up into Car, 16 Pin (This has nothing to do with my G35, I bought it so I can pull the three metal pins to connect to my G35 harness for the Wheel Controller (The Metra Axxess ASWC-1) without cutting or splice the original wire in my G35.) Well simply pulling the metal pieces out, and it will come right off. No soldering needed. 8 Option. Install Bay CCL1614 Crimp Cap Nylon Connector 16/14 Gauge Long Neck -100-Pack And obviously a crimb tool 9 Option. IRWIN VISE-GRIP Multi-Tool Wire Stripper/Crimper/Cutter, 2078309 Just make sure all the wires connect properly. And most importantly, get a friend or someone to help remove and install new radio.

I have a 2006 Nissan Maxima with the Bose radio no navigation. I wanted better phone integration while driving. I ordered a Jensen MPR210, the PAC ROEM-NIS2 and the Scosche NN1498B dash kit. I had to cal PAC with a couple of questions. The Jensen did not have an orange illumination wire PAC support advised to just tape that off. The Jensen had one blue wire for amp power on or antenna. PAC advised to connect both the amp power on and the antenna power to the blue Jensen wire. Finally there was the option of using the high or low level speaker outputs. PAC advised I should use the standard (black stripe) outputs and tape off the red stripe wires. Just soldered up the connections and plugged it in. The Scosche dash kit seems too large. I will have to work on it more to get the top of it flush with the rest of the dash trim. The Jensen and the PAC interface are awesome and it sounds as good as the old head unit did. The Jensen has a single "push to talk" button you hit to use Google Assistant that is much easier than using the old Nissan interface. All in all very happy.

Installed into a 97 Infiniti j30. This may have been a redundant purchase as it's so difficult to find a compatible wiring harness with the amp preout RCA connections, and depending on the setup this may be your only means to properly install the radio. Easy install with the only confusion being which positive speaker wires to connect, for radios with up to 25 watts per channel you'll only be using the low level red stripe cables, for all other head units (pioneers especially as they most all include 50w x 4) the high level wires will be the one you'll use. Fairly large and the the extra wires mean added bulk behind the radio, so this is also something to be aware of. Quality wise this thing allows the radio to function at its full ability and my what a difference. Excellent.

I have been helping a neighbor with an '04 Pathfinder SE equipped with the Bose radio/amp system. Battery was going dead in 2-3 days if the car was not driven regularly. Narrowed down the parasitic current drain to the radio fuses that provide power to keep the head unit memory working as well as being able to eject CD's when the car is off. Something inside the radio was 'on' full time and drawing a steady 1/4 amp (250 milliamps) even with car completely shutoff. Finally bit the bullet and installed a new radio head unit but wanted to keep the Bose Amp. This level adapter routes 4 high-level speaker outputs through 4 circuits and allows individual adjustment down to the approx 4v level the Bose amp requires on the input. I just turned up each level adjuster till I noticed some distortion and back it down an 1/8 turn. Sounds great and will drive you out of the car on high volume. No more battery drain, no more dead battery after sitting for week and not driven. This is the adapter you want if you are replacing a Bose Head unit. Others using RCA outputs put out too low a signal for the Bose Amp and results in low volume levels. Hooking the high-level speaker outputs to the Bose amp causes distortion. This is the way to go.

I just received this PAC ROEMINS-2 System Interface Kit today, so I haven't had a chance to fully install it yet. It's intended to replace the factory radio in my 1995-2002 Nissan with a Bose system and retain the functionality of the factory amplifier. I'm hoping this will finally solve the audio integration issues I've been having. The kit looks well-made, and the instructions seem clear enough at first glance. I plan to start the installation later today or tomorrow, so I'll update this review once I've completed the process and tested the system. My biggest hope is that this interface will allow me to upgrade my head unit without losing sound quality or other features due to the Bose system. I'll be paying close attention to how well it integrates and if there are any unexpected quirks. Stay tuned for an update!

Worked flawlessly in my 2000 Infiniti i30 although I did have to splice the blue and white wire with the red 12 v main to power the amps in my factory Bose system

Works as described. Easy install
