Whats wrong?? i have 2 ELA300.1 and i cant either one of them to work. i dont know if my wiring might be wrong but it worked when i first up it in. i have it hooked up to 2 12" MTX. RMS is 225 and peak is 450 for the speakers. when i put the second one in the other day the power light came on but nothing came out of the speakers. now the light wont even come on. when i had the old one hooked up it work but quit after a few days. so i got a new amp thinking i might have blowin the amp but now i cant get the new one to work.

You should check the remote wire bc you will get power to your amps if its not hooked up but you wont get any music!

Hi, You may want to check all the fuses. The amp power supply line might not be directly connected to the battery but passes thru the ign switch via a fuse, meaning it will only power up with the ign switch and the radio/head turned on. Another wire that you can check is the trigger on supplied by your radio/head unit. this is either blue or yellow color. Last that you can check are your speakers including the wiring. Make sure that bare wires are not touching any metal part of the car or the speaker themselves; finally, check your speakers, make sure that they are not open, shorted or grounded and that they really work. Better check by temporarily installing them in another setup or use a continuity tester which should show a reading of 4 - 8 ohms. Hope this gives you a few ideas. Post back how things are or should you need further information.

    Hi again,
    missed asking, have you checked your grounding? Double check to make sure amp is properly grounded to the chassis of the vehicle.

    Hi again,
    "ts the same with both amps" - then big chance there is nothing wrong with either of the amps. it's got to be the wiring;
    "i checked my speakers. they r 4 ohms" - did you use a continuity tester to verify if they're still 4 ohms?
    "i'm not sure if the speakers r to much for the amp maybe?" - two things here: 1. even if they were, the amps should still power on but then go to auto protect soon as it senses the speakers are "too much"; 2. as you posted initially, "but it worked when i first up it in." So it must be something that happened after the initial setup.
    There are 3 important wires to check, the big red which is always on or wired to the ign switch of the vehicle will measure 12VDC (use a VOM tester) or to the + terminal of your battery, the gnd or ground which should be body/chassis grounded or - terminal of your battery and the trigger which is a wire that comes from your radio/head unit which activates the amp also can be tested with a VOM. If your radio and/or ign is off there should be no 12VDC at this trigger wire but should have when the radio/ign is on, the big red wire should always have a 12VDC.

Compaq Laptop Windows 7 Acess Point Problem att 2wire

use wired Ethernet, so it works. easy.
wifi is far more complex.
best is to own the router, you have.
then login to it and set it up for wpa./wpa2
wep off.
and a nice password for wifi so others cant hack it. in the hood.
then use those credentials all all your toys. xbox, PCs and cell.
that is the best way
the access point is covered in you manual for the router
there is AP button there, you push.
the PC in question my guess is the drivers are no good.
missing wrong, or corrupted.
no PC full model stated.
no OS stated
no router stated.
so answers will be weak to wrong,.

My amp was working good and i didnt use like for two months and know it doesnt work the green light turns on but the red light too of over current and i cant hear nothing i dont know what is it..

if it turns red its a protection light you most likely got the ohms wired wrong on the speakers and the amp is going into protect mode so you dont fry it or the subs

My screen is not working, but the phone itself works fine, i know whats wrong w/ it, but i need 2 know how to fixit!!!GRrRrR!!! it has 2 do w/ the copper wires that connect the screen 2 the motherboard!!!...

if you want to fix it you still have to buy a flex cable for nokia 5300 to any service center that has an available, the risk is if you fix it and didn't work and got damage you cant replace the item anymore.
