does anyone know anything about electronics enough to help me out with my amp? ive replaced the fuse checked the ground and other stuff but its still blinking red and wont work.....plz help

 

Im guessing that is the protection light that is flashing. Check and test ground as well as ohm load. Has it worked in the past and just recently stopped working or are you just hooking it up?

Try unhooking the amp from the sub or speakers and see if it is still flashing red.

 

just purchased and hooked up, and i tried unhooking the subs from it and nothing changed, i opened it up and it didnt look burned out, and i also changed the fuse and it has a strong ground, and nothing wrong with the power source, its wired straight to the battery......i have no idea whats wrong?

 

Try checking the remote wire as well. Is the wiring kit new as well? If not make sure none of the wires are cracked.

I hope you didn't buy the amp new, as you will void the warranty if you open it.

How sure are you about the ground? Do you ave a voltmeter? I found that it was very difficult to ground my amp as there are no really good spots in the back of the xj. I ended up sanding and modifying the rear seat bracket to ensure that the ground was good. It seemed like everytime I would go over a bump my sub would go out. Haha

 

check out for loose diodes on the amp i had and amp brand new that i hooked up and ran for like a day or 2 and it stopped working come to find out it had a faulty solder job on 1 diode i re soldered and its good as new

 

ya i just bought the amp off craigslist and the amp kit from walmart, i sanded down my ground area im pretty sure it isnt my ground, my girlfriends step dad is an electrical engineer, ima take it to him and see if he can do anything about it, but if i can fix it myself i would love that, any more opinions?

 

Could be a bad amp as well. I am by no means an expert on car stereo systems. Best of luck.

 

what is a diode? and what does it look like

 

What all is the amp doing?

Flashing
Solid protect (redlight)

Pulsing

its flashing red every like 2 or 3 seconds, i could post a video if it would help?

 

You probably got had on craigslist. Did you see it work previously?
If it's going into protect, there is usually too low of a load on the output, or it's getting hot.

 

As stated have you ever seen it work? Is it new or used?

I've only found two places for a proper ground on a higher power system in an xj.
1* the seatbelt bolt
or
2* Drill a hole in the floor and put a bolt through.

 

Is the fuse between the power wire and the battery good? You mentioned you changed the fuse, but there are fuses on the amp and then a fuse between the power wire.

 

from my experiance with systems, the amp most likly is shot, theres something inside thats messed up, i run a single rockford fosgate on a 1000watt amp at 2 ohm's and i can throw my amp into protection if i run it too long or too hard , but at the same time ive also blew apart the magnet on a diamond d3 12inch sub with this amp, running at 2 ohms, and ive had a amp do that exact problem brand new out of the box, lol, i just picked up a set of subs and amp, just for subs, pm me if you want to buy a 1500watt amp, fairly cheap, i have no need ofr it, and yes it does work

 

if you have a dual voice coil sub or subs, you can bridge the sub (not to be confused with bridging the amp) and you have grate quality and a less likelihood of your amp overheating.
