    Installing sub+amp on standard car stereo.

    OK I want to install a sub+amp with my standard astra head unit.

    It's this standard delco unit; http://www.gumtree.com/posting_image...b3.__big__.jpg

    Questions;

    Is there a how to guide?
    How do I remove the standard unit?
    I've been told I need a red/white converter connector because the unit does not have it?
    How do I take the interior up to hide the wires?


    Anything else I need to know tell me!

    Thanks, Matt

    it's a pain in the ass mate tbh, the hassle that the phono convertors are it's worth buying an after Market head unit for £40. To get it out you need the stereo keys available at vaux or halfords. To hide the wires take your centre console up run them thrgh that come out near handbrake then under seat along plastic door trim lift up the rear seat bench and your through!

    If you get an amplifier with high level inputs you can use the normal speaker outputs to run a signal to the amp. i don't see why there should be a prob of running a second set of leads off the feed for the back speakers to the amp. proberly will be minro reduced volume... not much else.

    Any other way to unlock them using something less formal? lol

    I have bought the phono converter. Looks a bit naff but I will try and make a good job at connecting the wires. Just need to jimmy the H/U out now

    Ok so is there a guide on how to install them properly on a mk4 astra?

    Thanks, Matt

    Hitting trouble here. Taken the H/U out. Now I have a device which leaches power from the speakers to phono outputs. PROBLEM IS THE SPEAKER CONNECTORS ARE STUCK IN THE CAR AND I CANNOT MOVE THEM TO ATTACH THE LEECH DEVICE PHONO TRANSER LEADS?!?!?!

    I can see two small star key screws at each side of the plastic thing the head unit slides into, but I don't have any star keys to remove it.

    So what do i do?

    HELP!!

    Hello there i have actually ran my sub and amp off my Vauxhall standard Radio All You Need Is a High to Low Converter box http://shop.ebay.co.uk/i.html?_nkw=H...rter&_osacat=0
    Off Ebay Click the link
    All you need to do is connect these to your speaker cables behind your head unit and away to go this also means you will not lose your steering controlls or your display keep your car looking standard

    I Have also connected my subwoofer up to a switch on the lower dash by the ashtray (a Vauxhall T.C Switch)
    But You Will need to swap the guts of the switch with the guts from a MK3 Astra Fog Light Switch ...
