Is this needed for stereo replacement for a 2005 Nissan Murano SL with factory Bose audio system?
A shopper on Sep 5, 2015
Best Answer: Yes, you defenitly need it. My 06 pathfinder has tge bose system. the bose system has multiple amps that drive the speakers instead of just standard radio to speaker configuration. Make sure the aftermarket radio you are buying has at least a 5v rca preamp output or it will struggle driving the bose amp/speakers.

I want to add an amp to factory 2010 non bose non rockford fosgate nissan titan stock radio. I am getting conflicting information on what adapter to use to plug into back of radio and then goes to amp with rca plugs. Any idea which one is correct?

Best Answer: Hi Jon,

First, the Metra 70-7551 is an OEM-amplifier integration harness, for replacing the OEM Stereo - as such, it isn't the item you seek.

Unfortunately, there is no plug and play adapter for your vehicle. As such, you will need to chose between the traditional route of a LOC (line out converter) or a proper processor (like the Audiocontrol LC2i) . We suggest consulting your installer to make the decision.

I recently purchased a pioneer AVIC z150bh for my 2006 Armada w/Bose. I will be getting a free Scosche NN03B. After doing more research i came across the Metra 70-7551, this harness looks like it is a better fit for my needs since my vehicle has a stock bose amp. Is this right? or will the Scosche harness work as well? If not, would i be able to switch harness' on my order?
Emanuel I on Dec 21, 2014
Best Answer: Hello Emanuel,

The Scosche piece will work, the only concern is that the VOLUME may be FAR higher than expected, because you will be sending a HIGH LEVEL signal to the Bose Amp. Please give our sales team a call, to have the harness swapped out for the Metra piece, at no additional cost.

Carlos R on Oct 25, 2014
Best Answer: Hello Carlos,

Yes. This harness will be required to properly send the OEM Amp a proper signal, AND to actually turn On the amp. Take note, the harness requires FOUR RCA connections; So please make sure the headunit you wish to go with has 4 "Preouts" .
