I have two problems right now. I just brought my car out from its winter slumber, I recharged the battery and installed it, and I took the shoddy amp fuse that would cut out all the time and put in a new rockford fuse. The first problem is that my amp is not getting any power. I did a good job with the new fuse(i think), and I put the metal connector at the positive battery terminal and made sure it was tightly fit. I'm getting no power at all to it (i can tell because i have a small neon wired to the amp that is always on when it has power) Second, I have a Kenwood Head unit cd player that has always worked until now. It has power and turns on, but all it says is "All Off" when i turn the car on. I have tried every button on the face plate and nothing seems to be working...the only things it's letting me do is change the contrast and ridiculous crap like that...i can't even open the cd port! I know this is a far cry for help, but anyone who has any ideas of what I might be doing wrong please offer a suggestion!

Re: Amp and Head Unit not working! Plz help
The amp. You need a digital multimeter. Test for 12V at the amp. Not 6V or 9V, but 12V. I once had a huge voltage drop at the amp for some reason (been like 6 years, I don't remember why) and I didn't know that until I saw it on the meter. The amp wouldn't turn on until it had above like 11V. Safety feature. Test for solid ground. If you have those two things, then the reason your amp is not powering on is because the headunit is no longer sending the remote turn-on voltage. If you DON'T have 12V at the amp, check further back in the chain. (At the batt for example) You need to start troubleshooting. There is no obvious answer anyone is going to be able to give you for problems like these. Develop those troubleshooting skills. Start at some point in the chain. If the signal is bad/good, move up/down in the chain until you find the cause.
The headunit sounds odd. Both of these problems started at the same time? If so, then its HIGHLY likely they are related. -

so if my head unit isn't working properly... it might just be that it isn't giving my amp any power?Comment

Re: Amp and Head Unit not working! Plz help
For starters. The purpose of the remote turn on lead from the headunit is to turn the amp on and off. If the headunit is not powering on.... no turn on signal is sent to the amp. Thats just one small possibility. Start doing some troubleshooting. Then try to swap out some of your suspect gear with a spare or maybe a friends. Gotta work it man. The things I'm telling you are exactly what a "pro" would do..... minus taking a hundred bucks from your wallet.Originally posted by tkoforpresidentComment

Re: Amp and Head Unit not working! Plz help
i know i appreciate it, bear with me...my cd player does have power though, i just can't get it to go to the radio or cd functions and i don't know why. Second I replaced a bad fuse for my amp wire in the engine compartment and i'm sure i did it good enough for it to work. I checked my whole wire over and it all seems to be in tact, do you think my batter just doensn't have enought juice to it yet? (haven't actually driven it in a couply months)Originally posted by 96firebird311Comment

Re: Amp and Head Unit not working! Plz help
Are you trying to power everything on while the car is running? If not, TURN ON THE CAR!
The headunit may have power, but is not turning on. Its just sitting in standby mode correct? The turn-on signal is not sent until the headunit is on and ready to play some music. The reason I'm harping on the headunit so much is because the fuse under the hood and condition of amplifiers should in no way affect the headunit. The headunit should be acting fine regardless. The fact that it is not is odd to me. Again, get a multimeter and start poking around.Comment

arrr but i'm so stubborn and lazy.... so are you trying to say i might get some power if i DRIVE my car...cuz all i'm doin right now is letting the engine idle while i try to put them on.Originally posted by 96firebird311Comment

Re: Amp and Head Unit not working! Plz help
I had the same problem once with my amp, couldn't get any power to it and I checked and checked and checked the fuse like 20 times cuz thats what everyone was telling me to check, but the fuse seemed fine by looking at it, then I put a voltmeter on it to check and see if it was still good and the voltmeter beeped when I jumped the two ends together, so I thought for sure it was ok, so to make a long story short, the fuse was bad, seems like the carbon in the fuse allowed it to read good by the voltmeter, but when any kind of current tried to pass it couldn't handle it, therefore my amp wasn't getting any power, lol all that for one stupid fuse:rant:Comment

I just pulled out some ben & jerry's and a box of tissues.... sad story bro... the sad news for me is that i JUST put a new fuse in... a new fuse holder...it's a Rockford...apparently thats a good brand...and got the fuses that fit inside...i restripped the wires and stuffed them inside the connectors and tightened them down .... still no power.... :( i miss my musicOriginally posted by StiLlsMoKiN875Comment
