    AMP POWERS UP BUT NO READING ON AMP METER

  • David Crites May 11, 2010

    Do you mean that you are not getting any power to the amp.and if so do you have a fuse link in the wire. see if there is any soft spots in the wire around there and a the rest of the wire because that means that the wire is too small and that you need to get a bigger wire.

I have 2 amps instalkled in my car one is sony 1200w 2 channel amp for speakers and one is solid audio f2500d for 3 subs my sound and every thing was good but suddenly from yesterday im having trouble when...


First disconnect the CD head unit from the sub amp and see if the other amp works. If yes, the problem is the wires to the amp, the amp itself, or the subs/sub wiring. If no, the problem is the head unit--probably an internal short.
If the other amp works with the sub amp disconnected, reconnect the sub amp to the head unit, but disconnect the sub wires from the amp. Try the CD player. If the amp goes to protect with no speaker wires attached, the amp is bad. If the amp is OK, the problem is the subs or sub wires. Hook the wires up to the amp again, but disconnect them from the speakers. Try the player again. If the amp goes to protect, the problem is the amp wiring. If not, the problem is the subs. Check the impedance of each sub using an ohmmeter to determine which amp is out of spec.
Please let me know if you have questions, and thanks for using Fixya.

Make sure that you have power at the amp; test the power wire at the amp. If there is power at the amp; check for a good ground at the amp.Check for fuses at the amp. If you have power and ground at the amp, the issue may be with the amp.

Not powering up no current tried every thing


Hi apart from the + & - connections to the big terminals, the terminal marked "REM" or "REMOTE" needs 12 volts on it too to start the amp up.
If no joys then check the following in this order:-
ensure amp has a good 12v supply & good ground.
remove & inspect the fuses on the amp
disconnect all speakers and retest amp.
if all this stillresults in a dead amp then the only answer from here is service to the amp.
ENSURE THERE ARE NO SHORTS IN THE SPEAKER WIRING TO EACH OTHER OR VEHICLE GROUND - this will kill your amp.

I have a similar setup & I just run the second amp straight off the other amp by running positive & remote wires directly from 1 amps positive & remote inputs to the others amps inputs. But my head unit has RCA inputs, (sub in & front & rear inputs) so from my 4 channel amp I run 2 6 inch alpine S's to the front to the front RCA inputs of the head unit, & 2 Pioneer 440w 6x9 inch speakers to the rear inputs. & my 800w 12 inch sub from my 2 channel amp to the sub woofer inputs on the head unit. Has blown my eardrums for nearly 12 months now great stuff! Hope this has helped

Subs and amp dont work


His amp probably blew your fuse. Check that you have 12V at the power connections. If you don't, then find the fuse in your positive wiring to the amp. If you do have 12V to the amp, check your remote power up also has 12V between that and the negative line when your head unit is on. If it doesn't, then it's probably an internal fuse in your remote switch on line inside your head unit caused by a fault in your friends amp. This is normally accessible at the back of the head unit.

Amp stuck in protection mode, help!!


for 1 the amp is no where close to strong enough for the subs and 2 if the amp is mounted on the box it is vibrating the electronics loose. you always want the amps rms power to be be about 25% more than the speakers rms rating, from the sound of it you are either undriving the amp (clipping) or running the amp at 1 ohm load which is making it burn up. if the amp gets hot (which class d amps should never ever do) then try running just 1 sub. if the problem goes away then you know the amp is not enough for the subs. try a hifonics amp you will be amazed at the quality and power difference. I sell all major brands cheaper than almost anywhere. let me know the exact model of the subs and i can recommend a better amp for you.

Have you checked to see if your subs voice coils have shorted. That could cause the amp to heat up, on rare occasions the protection lights don't work. Rare, but possible.

No power to the amp i touched the power wire to the side of the amp


It probably burned a trace on the circuit board.

With the amp hooked up normally and the head unit on (so the amp will have remote voltage), do you read 12v DC anywhere on the case of the amp (black meter probe on the ground terminal of the amp)?

If there is no voltage on the case, confirm that you have 12v on the B+ and remote terminals of the amp (black probe on ground terminal of the amp).
