    I have looked all over and can’t find the amp in the trunk under the floor covering. Do you have any pics that show the location?

    Art, try lifting your trunk floor covering where your spare is located. Now look toward the front of the spare (right behind the bottom of the rear seats), there should be a black plastic cover there. Try looking behind that, you should see the factory amplifier located there. Hope this helps. Good luck.

    i had a speaker that kept going on and off in the front door so i replaced the speaker and it still didnt solve the problem i was wondering if maybe it had something to do with the amp it has the bose system and navigation in it ? Thanks

    Matt, bose system’s have independent amplifiers for each speaker. Double check that the ground on that speaker’s amp is well grounded. If it is, your amp may be faulty or the audio signal coming from your factory radio may be faulty. We suggest you take your 2003 Nissan Murano to an experienced audio installer and have them troubleshoot your problem. Hope this helps. Good luck.

I have a purring in my amp and am wondering if it may be the ground wire.Being rather unfamiliar wiht any car knowledge i would like to know where to look for this and what i should be looking for. I also had some success fiddling with the fuse for the system but that no longer works.
