    the cd player is broken in my car and i was wondering if there is any way for me to get the cd out of the cd player and like how do i get to the cd player to look at it?

    Amanda, if the CD is stuck it would require you to take apart the radio. If the CD is important to you, our advise is to take your radio to an experienced radio installer and have them take apart the radio to remove the CD. If the CD is not that important, it would be cheaper to purchase a new CD rather than pay someone to remove it from the radio. Hope this helps. Good luck.

    I have a nissan titan 2004 and i bought a adaptor to the factory hook up. The big adaptor will not fit b/c their are some wires that do not match. Could you tell me what I need to do?

    L.J. Amandas, it sounds like you may have the wrong harness. Contact the vendor you purchased the harness and they should be able to point you to the right harness. Hope this helps. Good luck.

    i have a 2004 nissan titan it came with the rockford fosgate stero package i recently installed a new cd player but i think my amp above the gas pedal is bad bc the only speaker that works is the stock sub under the driver seat i had this same problem with the stock cd player i had the truck for about three months and first the front speakers went out then all of them except for the sub 1. is there anyway to bypass that amp without rewireing every speaker? 2. if so should i wire it straight to the head unit using the wireing guide above or is that possible 3. what would you suggest? Thank you for your time.

    can i add subs and a amp to the factory six disk in dash

    Richard, yes it is possible to add a subwoofer and an amplifier to the factory radio. It does take some wiring knowledge and installation know-how. You would require an aftermarket amplifier, amplifier wiring, subwoofer and a speaker to rca line out converter. Here is the Line-Out Converter you need:

    Scosche 2-Channel Speaker to RCA Line Out Converter

    When splicing in the RCA Line Out Converter, tap your factory rear speaker wires to get a full range audio source. We suggest you invest in some solid wire taps that wont come loose. These wire tap connectors will allow you to tap into wires without cutting and installs in seconds by hand with no crimping or tools required. If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your subwoofer and amp installation.

    I have 2004 Nissan Titan with a Bose 6 CD changer w/o satellite radio. Can I retrofit it with a satellite radio kit? I know some models came with the SR option, but this one didn’t. Thanks
