Won't turn on!

Hi, I just hooked up my JBL amp and it just won't turn on... I am confident in my wiring and even checked the voltage where it enters the amp with a multimeter and got 12 volts when the ngine is off and about 14.56 when it's on..... what do I do from here?

do you have a good ground? Is the amp new or used? has it worked before for you if it is used?

seeing as how my multimeter says i'm getting the voltage i need... I'd assume i have a good ground... I purchased the amp off of ebay where it was said to be new.

short +12v terminal to the remote terminal on amp and see if it comes on.

Alright, you're awesome... I now have the power cable connected to the 12v+ and then a small wire going from 12v+ to REM and it works! I'm now pushin some serious air. Thanks so much.

wouldn't that cause the amp to stay on even after the vehicle is turned off? I'm just wondering because this is the same problem I'm having right now. Also, Mr. Lucas Beckner whats a good place in Tulsa to have car audio done? just wondering because I live in Catoosa and I need a reputable place to have audio work done.

Yeah. Zack that was a test to see what the problem is. If you have an aftermarket deck then you need to run a wire from the remote on the deck to the remote on the amp. This will turn the amp on/off with the deck and save your battery. Otherwise use a switch to turn it off manually.
GMG, I do my own work, but I recommend Streets Audio. Ask for Mike. He really knows his stuff. Tell him I said hi.

Thanks for the recommendation. As for trying to solve the problem... if the amp is already hooked up to the deck via the remote wire. and the amp still won't turn, what could that be? . (this is before I try the test mentioned above)

Oh yeah, I used a multimeter as well and power is getting to the amp

I just performed the test and it worked. The amp turned on and the thumping started! Now my next question has to do with the remote wire. I have the remote wire connected to the blue wire from my wiring harness that reads "amp" and it still does not work. What could be the problem?

go to your radio/cigg lighter fuse in your fuse box.

do you mean wire my remote wire to the fuse box or check those fuses? The fuses were fine except in the cig lighter. And if I should wire the remote wire to the radio fuse in the fusebox, how would I go about doing this?

yes run your remote wire to your fuse box. any accesory power will do just fine. I just named your cig lighter or your radio because they a accessory ignition fuses.

How do I go about running the remote wire to the fusebox? Would I have to find a wire behind the fusebox or run it into a fuse?

GMG, The remote wire on the back of the deck is usually blue w\white stripe. Another alternative is to use a switch hooked up to +12v on the radio and on the remote on the amp. Then you can turn the amp on/off with the switch.

just run it to the fuse box and you dont need to use a switch.

Adam, if you disconnect the speakers will the amp stay on? If it does then maybe you've overloaded the amp. How do you have your speakers hooked up? And how many ohms are your speakers? are they single voice coil or dual? If you have the amp bridged in mono then the lowest load the amp can handle is 4ohm. If the amp is in stereo then 2ohms per channel is the lowest impedance.

How are the speakers hooked up? You should not have the amp bridged. You should have one speaker to each channel on the amp.

Adam, The components missing off the circuit board is normal. Unless they were burned or broken off. It sounds like maybe the amp is damaged. It probably occured when you bridged it too low. Maybe you could tell the people you brought it from that it was dead on arrival.

I have a pioneer TS-3000T amp in my car and i've confidently wired it...i know it is getting 12 volts because the multimeter says so but the blue light on the amp that is supposed to turn on when the car is turned on just flickers and goes out soon after ignition. The system control wire is connected to the amp wire on my harness and I have a solid ground. It is not sending anything to my sub either, it is brand new.

Make sure your in the right remote turn on. I know that sony has a blue and a blue and striped wire for remote turn on, and you'd want to use blue striped for it. Im assuming the rest are like this too.

when they make the beadboards in the factory they don't always need all the components. maybe this is due to schematic changes. but if it comes out of the factory with a component missing then it is probably normal.

ya but do you know what would cause the protection light to stay on and the power light to flash? even when no speakers are hooked up it does it when only the 12V,remote, ground is connected to the amp and my dome light flickers as if the amp is drawing power.....

try changing the terminals that the speakers are attatched to. i had a problem with my amp light going on and off and once i changed the speaker terminals round it worked. worth a try anyhow....
