Yes | No 5 out of 5 1999 Mercedes Written By Rob, New York, NY on Sunday, November 08, 2009 Used this interface to install a new head unit in my 1999 Mercedes c280 with Bose system. Attached all the wires to the supplied harnesses following the documentation supplied by Crutchfield, plugged it in, and not one problem. Didn't have to make any adjustments or anything! 3 out of 3 people found this helpful Was this review helpful?

Finally had time to finish project and ordered PAC OEM-2 based on advice from Crutchfield representative. Technical support was superb and patient with me through completion. Now OEM sub-woofers and OEM amplifier work as designed and I must say the entire system sounds great especially considering the small amount of money I spent for the PAC OEM-2. A great choice! 3 out of 4 people found this helpful Was this review helpful? Yes | No 5 out of 5 PAC OEM-2 Written By Marcus, Santa Clarita, California on Tuesday, May 05, 2009 My Mercedes-Benz CLK has a factory Bose system. The Bose system in my car has balanced differential amp input connections. The output from most aftermarket head units is an unbalanced signal. A person "could" plug unbalanced preamp outputs into Bose system amps, but the result will be inadequate signal amplitude. The PAC OEM-2 corrects the signal. If this sounds confusing to anyone, I'll make it as simple as possible - if you're using an aftermarket head unit with a Bose system, it will sound better if this box is used. 9 out of 9 people found this helpful Was this review helpful?

Crutchfield should consider another solution. 3 out of 4 people found this helpful Was this review helpful? Yes | No 3 out of 5 Didn't Use It Written By propflux01, Central Arkansas on Saturday, January 17, 2009 Product was shipped to me along with a Pioneer FH_P8000BT Tuner and all the other stuff to install it into my 2006 Hyundai Sonata with factory Sub and amp. This was to be used in conjunction with a Ford-style adaptor. I took one look at this and thought "Geez, how many more wires I gotta deal with, and where is this thing gonna fit along with the HD tuner, wires and other stuffI am cramming into my dash?" After a little research, and trial and error, I found that for the factory Sub system, my needs would be better served buying a different harness. WAY much simpler, has added wires for proper operation of the steering wheel remote, which the harness Crutchfield sent didn't. 3 out of 3 people found this helpful Was this review helpful?

Written By ALBERTO, San Juan, Puerto Rico on Saturday, January 10, 2009 CASE STUDY: 2000 LR Discovery w/Harmon Kardon high end factory system. Factory head unit made by Alpine burned out so a replacement was in order. I hooked up a Sony CDX-GT820IPod to one of these OEM-2's and it worked pretty decent. After a week of driving I was upset with the overall fidelity. If you're like me, an old song is like and old friend and we know it's every nuance. That combined with the fact that I know what those Harmon/Kardon speakers could do left a sour taste in my mouth. Here's what was happening...A new premium head unit (in my case Sony) was putting out a clean line signal into the OEM-2 only to have it "knocked down" to safe level for the car installed Harmon/Kardon amp to able to handle it. The amp in turn would take this modified signal and kick it up again. The signal degradation was unsatisfactory for me. Word of caution, I did verify that the speakers did not have chassis ground and the LF & RF low freq were put in parallel with the LF & RF high freq leads. the MID & TWT had filter caps and the head unit was put at a 125Hz LPF mode. A small mono-block with a ten sub to top it off and now I'm smiling baby! I can see this item being very usefull in some weird vehicle applications but in my opinion, your overall sound quality will be compromised a bit. 1 out of 1 people found this helpful Was this review helpful?
