Dr. Johnson Posted March 22, 2009 Report Share Posted March 22, 2009 Whats the chance that I got a bad amp? I have had a problem with my system since I put my SAX 100.4d in. I went and bought a new cd player thinking that it was my Alpine. That was not it. I changed Rca's thinking that could be it nope. today I went out and played with it more. It sounds like there is a bad ground. I unhook all rcas the sound goes away. I hook up one the sound starts only in the rear speakers. then add another rca the sound is worse add the other two noise lessens buy still bad. I unhooked all speaker wires and hook up each one at a time no noise noticable until the last one drivers side rear is hooked up then its real bad again. I unhooked all rcas and hooked up the sub rca the noise is there. I thought maybe the speaker wire in the right rear was pinched somewhere so I removed it and hooked up new wire from amp 18 inches to crossover. noise still. took woofer itself and noises still. I try the passager side on the same amp out put noise is there. I drive an explorer my amps are on the box behind the seat. the box is above the wheel wells and there are 2 XS power batteries under the box behund the amps closest to the SAX and there is a red top behind the passenger wheel well panel. all amps hooked together one wire of 1/0 from fron battery to red top then to the XS power's. The XS power batteries are both grounded to the frame and the body through the same 1/0 wire and the red top is grounded to the body. ANY IDEAS WHAT COULD BE WRONG????? thank you Quote Link to comment Share on other sites More sharing options...
bigbodylexus Posted March 23, 2009 Report Share Posted March 23, 2009 how are your wires ran?

finkster Posted March 23, 2009 Report Share Posted March 23, 2009 Did you try grounding your RCAs? Ive seen this problem fixed a lot from doing that Quote DAT 4125------>RE XXX comps active Eclipse cd7000 I serve drunks for a living Link to comment Share on other sites More sharing options...
Dr. Johnson Posted March 23, 2009 Author Report Share Posted March 23, 2009 I did not have this problem until the SAX and new batteries came into the mix. wires are all apart until they enter the box then they are next to each other.

sundownz Posted March 23, 2009 Report Share Posted March 23, 2009 Have you tried to temporarily remove the batteries to isolate if that is part of the problem ?

Team_DC-Derrick Posted March 23, 2009 Report Share Posted March 23, 2009 (edited) have you tried unhooking your crossover and just wiring it to the amps? ...

Dr. Johnson Posted March 24, 2009 Author Report Share Posted March 24, 2009 Sundownz: I think I will unhook the 2 xs powers and try just the red top to see if it works then I will try just the front one. Do you think I would need both amps hooked up at the same time? I have an SAZ -1500D and a SAX-100.4 . Army_guy614: I do not use a cross over I go from my Head unit to the amps. Thanks for the thought though. Quote Link to comment Share on other sites More sharing options...
Dr. Johnson Posted April 12, 2009 Author Report Share Posted April 12, 2009 OK So I worked on my system last night. Put in my new SAZ1500D and looked for a reason that I would have noise in only one speaker and stuff. I looked and looked I was ready to pull out all the batteries and start at the beginning and add one at a time. I pulled the SAX100.4 off the rack and set it in my lap and started by hooking up all the wires and there was no noise. I wiggled the wires and noise was there then it wouldnt come back a pressed lightly on the speaker terminals and the noise came back. I was thinking damn ups must have dropped it hard enough to dislodge the terminals. But that wasnt it either it turns out that the bottom of the amp is so close to the internals that it was pressing on the internals and shorting something out in the output section. Now what Can I do to layer the inside of the bottom panel to prevent it from shorting out when it is tightened down. I would prefer to use something that is not slapped together like tape so please do not suggest that. Thanks for the help in advance.
