    grab a 72amp battery (specifically for Astra G) Part number 93176583 - prices vary from £40-60 depending on if ur in trade club etc.

    Alternator - NO a diesel one wont fit - youll need a specific petrol one....youll need a 120amp unit but if ur serious about one - let me know I can put u in touch with someone who might be able to help.

    what engine have u currently got?

    defo get an uprated battery, 72amp really is the best u can get for ur car. The alternator can be had 2nd had for about £40 - I'll pass ur details onto someone if youll defo be interested in say a few wks time or so.
    As ur running ICE then Id stongly recommend uprating the earth/power cables to make the most of the uprated power once u get them.

    NEW battery to body (earth strap) at least 4AWG
    NEW gearbox to body at least 4AWG - pref 0AWG
    NEW power & earth charging leads from Alt to battery - again 4AWG
    NEW starter to body - 4AWG

    this way if ur running 4AWG from the battery to amp and u still have the standard 8awg or so from the alt to the battery - u wont benefit from having 4AWG to ur amp.... u need at least equal from alt to battery to feed the amp.

    Hope that makes sense.

    Where is the best place to pick up 2nd hand alternators from?

    Had a look on ebay but I dont really know which i need.

    Sorry about the thread hijack

    For your setup maybe a deep cycle battery in the boot would be a good idea?

    no need for 2nd batteries or powercaps yet imo. Sort out the basics first then maybe consider this option.

    you have to be lucky to snap up the right alternator on ebay - I know someone with a "contact" who should be able to sort out some uprated alts...all I can say is watch this space and it'll be posted up here in due course.
