    Okay, I guess then it's really not such a great idea to use the wire harness +12v to power the contraption. I know next to nothing with regard to electricity and wiring.

    I'll get my *** to Radio Shack and pick up some 10 or 12 gauge wire then and wire directly to the battery +. Is there anything I need to take into consideration other than a fuse, when wiring directly to the battery then?

    Regarding the fuse: How large of a fuse would I want to use with the Opus 150W? Would I be correct in the assumption that I would require a fuse in the range of 12.5A?

    Thanks..
    FYI the smaller the guage number the bigger the wire, ie. 8 guage wire is thicker than 10 guage. 0 guage is the thickest.

    I think you should use a 15A fuse, on the battery side of the wire, within a few feet of the + terminal. Let us know if this solves your problem. Good luck.

    Thanks everyone for all your tips. You've given me some great material to work with. I'll let y'all know how it works out once I get the Opus.

    Peace..

    my problems were occurring even in the hot weather :S right now its taken a turn for the worse. I've had the fuses unplugged for days and the opus wont reset itself. I think the voltage is dropping too low during cranking and the opus goes into protection everytime.

    and for the record, DSG is second to Torch Red

    If after all those fix/change and you still have problem, check the battery.
    I mean look in to more cabable battery than stock. I don't think the charging system have problem cuz the car is verymuch brand new. And car these day have very cabable alternator.

    lol DSG is my second fav colour on the mach's, but probably my fav on gt's (I dont think the torch red looks that great on gts, on the mach with the different hood it makes the body lines just jump out).

    I've tried different fuse ratings, I've tried checking my grounds, but the problem still keeps happening. I'm assuming it must be something to do with the battery severely dropping during cranking because the other day (before it blew) it was working fine. I parked the car for literally 2 minutes and when I came back the system wouldn't boot up.

    If you check back on the other thread you msg'd me about, you'll see its working again. Either I was a complete moron or my car is punishing me for putting 20,000km on it since I got it back in july

    Hey, just a quick update:

    I got the Opus 150W in the mail on Saturday and installed it yesterday, wired directly to the battery. It seems to be working, although I wasn't able to test whether or not it worked from a cold-engine startup. I'll test that when I get home today.

    I should have just shelled out the extra money for the Opus in the beginning instead of wasting ~$90 for the ITPS which didn't suit my needs and the PW200 which blew up. Oh well. Chalk it up to experience.

    Thanks to y'all for your help.

    Just another quick question, I haven't looked over the Opus documentation yet, but can the Opus 150W also control/delay amplifier turn-on?

    Pece!

    Dave

    i'm not sure about the 150w, but there is a $15 extra charge for the 90w for this harness. Provides a 12v signal 20 seconds after the comp turns on to power on auxiallry devices, ie: amp
