Phoenix Gold Phorum

Ok, this might be a lil long "winded" but I dont wanna forget anything. Currently I have 4 RSD DVC ten inch subs running two ohm stereo on an RSD 500.4. Recently the amp stopped working but everything else kept working. I checked each sub and they were fine. I checked my gound to the ground block and it was fine. So I took the amp out, a lil prematurely...... I have one ground to the frame going into a monster cable ground block (w/no fuses) and four grounds coming out. 2 pg caps are individually grounded along with the 500.4 and my midrange amp, 300.4. Everyground is snug inside the block but the ground from the 500.4 is reading bad on my meter.... Its secure as hell but its showing bad?????

1. Can a ground cable that was installed correctly two years ago in a dry clean area just quit working?
2. OR, can a big as ground block just stop doing its job on one of the four grounds????

Plan on running a new single ground for the big boy and seeing if that works, but I am super stumped with why it aint working????

when the amp quit working, did it go into protection or did the power light go out completely?

have you tryed disconnecting the ground wire that is reading bad and check to see if it may have arked out? weird stuff happens ever so often.

I forgot to mention that part!!!?? When the stereo comes on and all the stuff in the back starts getting power the big amp doesn't do nothing.... no power then off and no protection light, ever.

BUT.... If I got everything already turned on (minus the 500.4 of coarse) and I remove the inline fuse on the power wire running to the 500.4 and replace it the amp comes on and turns off immediately. You hear it click on then click off quickly then the led's just fade out.....

What is arked out?? I've been doing car audio stuff since I was 15 (17 years) but I was self taught and have never heard that phrase or had it happen before??? Do u think its something I did??? or just bad luck/cable???

when something like a wire or electrical contact dosent make a good connection or has to much current flow trough it it can become arked out. it's sorta like being burnt up but it is with copper brass or gold when it is arked out it will not make up the same contact as it should. some thing's that have been arked out can be cleaned and reused and some times wire can be cut shorter to take out the bad spot.

!!!!!!!thanks!!!!!!!!! to say i was/am stumped is an understatement! hope to be flexing my roof again tmro!!!!

I know this is stupid sounding, but have you checked fuses?

yeah, i replaced the fuse under the hood and both in the back at the fuse block. NO LUCK! I ran a new ground wire and its knocking pictures off the wall again!!!
