• Amp wiring. Some weird crap, even when not connected it shows 30V

Hey, sorry if it's wrong section but not sure where else to ask, so mods please move it if it's wrong. [img]http://i411.photobucket.com/albums/pp196/arleitiss/Untitled-1-10_zps45daa76f.jpg[/img] Basically that's how I got it wired. It's amp + sub in a box. Still doesn't work though. Fuses are okay, all checked. If I check the voltage with meter it gives out 24-30 V for some reason. If I put Positive stick to 12V and negative stick of meter to GND it says 24. All checked, all wires feed a power but still doesn't work. I got non default stereo however I don't have a switch or any other wires like that. Or at least it doesn't work with the blue wire. Any idea what the problem could be?
Remove the step up transformer you installed in your car???? Is you meter OK? What does it read when you just meter between the posts on the battery?.. If it doesn't rear system voltage (12ish) there's something wrong with it. The only other possible explanation is that there's something terribly wrong inside the amp itself, where the circuit that boosts voltage to the rails is finding continuity to the power inputs.. but I can't say as I've ever seen that, ever. That's the only way possible I can think you'd find anything higher that system voltage, though. Pull the amp and bench test it. I use jumper cables clipped directly to a battery, then clip some short bits of wire to those. Positive to + and remote input, negative to -. See if it turns on. If it passes, feed it some sound with an aux cable ([url]http://s1.static69.com/hifi/images/produits/info/xl/HRCA.jpg[/url]) and and Ipod. If everything benches OK, we've got something we're missing on the install. If it doesn't bench OK, replace it.

Sand the paint down first. Paint is not conductive and will simply get in the way of a good ground. Also, consider using a different source for your signal wire. Using the remote-turnon wire for your stereo is a much wiser option.
Got it fixed, scraped some paint off using screwdriver. Works like charm now.
Lol oh goodness. As a wise man Mr Ron Gold once said "Always Scrape"
I just don't have a sandpaper, so I had no other choice :v:
I use the edge of my crimpers, works good. Cut, strip, crimp, scrape, and run a self tapper in with a star washer.
