Ben H Posted March 3, 2006 Report Share Posted March 3, 2006 Heysooo....the other morning I noticed I had no bass...which is odd considering I have 2 12's so I went and checked if anything had come un plugged and didn't notice anything.BUT i found that my amp isn't on...its a kenwood and has a blue light that should be on and its not. Now befor you suggesst things here is what I checked allready: Main power cord is conected to the amp and to the battery connections look good. The 2 fuses in the amp both look fine and the fuse in the main line looks fine as well.Any other bright ideas why my amp wont turn on any more?Ben Link to comment Share on other sites More sharing options...
the underlørd Posted March 3, 2006 Report Share Posted March 3, 2006 hows that 1) Ground, 2) Remote turn on lead. ? Link to comment Share on other sites More sharing options...
Ben H Posted March 3, 2006 Author Report Share Posted March 3, 2006 Both of those connections look good on the amp side....I will have to trace them to their source....but its frickin cold out right now! hahaBen Link to comment Share on other sites More sharing options...
highhighs Posted March 4, 2006 Report Share Posted March 4, 2006 if you can get a volt/ohm meter check the voltage on the power line and the resistance on the ground wire, i had a main fuse once which looked good but for some reason was only letting 3V to the amp.

Bing_0 Posted March 4, 2006 Report Share Posted March 4, 2006 easy way to tell:take a little wire, strip both ends, and put one end on the power terminal, the ohter on the remote terminal, if it comes on, then you know:1. you have a good power wire2. you have a good ground wireand then its pretty much the remote turn on wire, either the wire died, or fell off behind the headunit.if it does NOT turn on, then take a long piece of wire, first run it from the negative termianl of the battery to the ground terminal on the amp, repeat the procedure above, if it turns on this time, then its a bad ground, either the wire is broken, or its loose at the contact point.if it does NOT turn on, then take anothe wire, and go from the positive termainl of the battery to the positive terminal of the amp, and then again, repeat the fisrt procedure with connecting the remote terminal with the positive terminal, if this works, then you know you have a bad positive wire, either the fuse is bad (often fuses fail even though the arent blown) or somewhere along the line, the power wire is dead or not making contact with the battery terminal.if again, nothing, then you my freind, have a bad amp.process of elimination my friend b Link to comment Share on other sites More sharing options...
AnthonyR Posted March 4, 2006 Report Share Posted March 4, 2006 Or if you have a multimeter just clip one lead to ground and touch all three terminals (obviously looking for ~12V on the power and remote turn on, and switch to ohms for the ground terminal and your looking for under 2 or so definately (but should be as close to 0 as possible)In all honesty, it's probably your fuse, even if it looks fine, I have seen a fair amount failing as of recent (and fuses of all brands and sizes, it's been wierd) Link to comment Share on other sites More sharing options...
Ivanfbi Posted March 4, 2006 Report Share Posted March 4, 2006 Is it the Kenwood KAC-929 or alike? those amps die like ++++++ I had 2 of them, both dead right now Link to comment Share on other sites More sharing options...
Ben H Posted March 4, 2006 Author Report Share Posted March 4, 2006 HUmWell I havnt had time to do the full series of tests Bing sugeseted (thanks for those!!) But I did try and bridge the power and remote with no luck. I also found that my Highs amp isnt on either - its power line splits off from the big amps. SOOO I am betting its that main power line (hopefully just the big fuse)And yes it is the Kenwood KAC-929 but it have been very solid in the past...no dectectable signs of it getting weaker or anything like that.Before I do this I figured i should ask - can I take the main fuse out and press the big wires ends together (the ends that would couple the fuse) to see if that indeed is the problem? - or should I really keep a fuse in there ? This would only be for a quick test.Ben Link to comment Share on other sites More sharing options...
AnthonyR Posted March 5, 2006 Report Share Posted March 5, 2006 Yeah, I have the KAC-729S and I've been rocking that for over 6 years now, and I've never had a problem. Link to comment Share on other sites More sharing options...
highhighs Posted March 5, 2006 Report Share Posted March 5, 2006 most probably nothing will happen(harmful that is), just get someone with you to check if the amp turn on Link to comment Share on other sites More sharing options...
Ben H Posted March 10, 2006 Author Report Share Posted March 10, 2006 WellI finally got around to switching out my main fuse.
