lanman31337 Posted July 3, 2009 Report Share Posted July 3, 2009 (edited) So something like this doesn't happen to me every day, and this is probably one of the first times I have witnessed it. Now I was doing some things, a buddy of mine let me borrow a known good working radio until my DVD player comes in. So I hook it up, it goes into my JBL eq, and then from there into my Opti 600.4 via RCAs. This is where things get weird. I had some car problems today, so I disconnected the negative from my amp and my EQ at the rear battery. The positive is still hooked up. I have the remote turn on into the ignition wire. When I got the car started, the amp turned on. There was alternator whine. Again, the negatives are disconnected. As soon as I disconnected the RCAs, it shut off. I tried with another set of RCAs, thinking it was pinched, same thing happens. Discuss please.

Chris from Mi Posted July 3, 2009 Report Share Posted July 3, 2009 sounds to me like the amp is grounding itself through the frame of the amp to the frame of the car, maybe grounding through the rca's but i doubt it. Is the amp in any way touching the body of the car?

Is the amp in any way touching the body of the car? It very well could have grounded through the RCA's, happened to be a while back I pulled the ground with the positive still hooked up and fried my RCA had to get a new set for it to work again, always disconnect power before working on any connections on your amp.

Is the amp in any way touching the body of the car? The amp and the equalizer are on pieces of wood, and neither are touching the body of the car at all.

lanman31337 Posted July 3, 2009 Author Report Share Posted July 3, 2009 I had a similar scenario with the radio that was shipped to me, had to have been a bad radio, but if I hooked up just the constant power and any of the RCAs, i get power to the radio. Note that the ignition wire was not even connected. Another part to this is I got out my multi-meter, and checked the outside of the RCAs on the amp to the negative battery terminal. I'm getting damn good continuity on it, and I don't think I should be :~ Quote 2 - Audiopipe AP30001Ds 1 - Lanzar Opti Scion 600.4 4 - Lanzar Optidrive 1232D's 1 - Lanzar Opti 5.1 1 - Lanzar Opti 6.1 1 - Lanzar Opti 6C midbass 1 - Alphasonic PCT6551 1 - Lanzar VX830 1 - JBL 22 band EQ 1 - Lanzar SDBT75NU 1 - AudioControl Epic160 Link to comment Share on other sites More sharing options...

lanman31337 Posted July 3, 2009 Author Report Share Posted July 3, 2009 Glad you guys mentioned that. I do not have the antenna hooked up at all. I do have a "hot rod" style antenna since I shaved mine, it's under the back deck and hooked up to a ground, however the antenna is not hooked up.

basshead4life Posted July 3, 2009 Report Share Posted July 3, 2009 its grounding thru the rca cables because signal only goes the center pin the flat outer piece is grounded for protection. so if you try to play music and your rca is being used as a ground youll probly set the rcas on fire Quote Team S.M.D. Maritime Car Audio- (2) 18" SSA ZCON D1 - American Bass 500.1 - 60 ft of 3/0 -480 Ah of battery - (2) stock alternators (70 +90) - Kenwood Excelon x-794, 4v preouts car audio is just a LOT more complicated than "this amp does this power" or "this sub will be this loud". its like 2 + 2 = banana. (if that confuses you then you get the point) lol Link to comment Share on other sites More sharing options...
t-money Posted July 3, 2009 Report Share Posted July 3, 2009 well if u take out the rca's it shuts off. so its grounding through the rca some how. no ground to your deck at all? does it mount to metal in the dash?
