Question about Bazooka EL1500 Car Audio Amplifier

El1500 turns on but so sound

Hey there, my EL1500 will turn on with a red led light but puts out no sound. Tried wiring at 2 ohms and 4 and still nothing. Ground is good, power is 12.9 volts and remote wire has 11.5 volts. I opened the amp and the only thing I saw wrong was a capicitor toward the back of the amp (the end with the wire connections) had part of the shrink wrap melted off of the side of it. The side of the capacitor said SamXon 3300 micro farad 35V. Would this be my problem? Should I just get a new capcitor and replace it? Thanks, Rob

    Try new cap there. Should be another of same value right beside it replace it. Also the check. Pwm regulator pin 1 to ground less than 1000omhs. Regulator bad if has numbers like tl494 6bucks sm3525 easy fix

Hello fordguy, love the name i'm a ford man myself if thats why you chose it. Anyway to the amp. I buy broken amps all the time from E-bay and find which parts are bad order them and replace them and the amps work great. I just bought and recieved the same amp, Bazooka EL1500 and right away when I put power to it the protect light came on. Let me tell ya a little about car amps and the mostly the main reason they go into protect mode. First it could be something small and stupid like a fuse, sometimes amps protect light will still come on even if fuse is blown. Maybe something inside is touching something else causing it to go in to protect mode like lets say a small peice of solder is connecting to solder traces together or whatever, you get the idea. Second and this is I'd say 80% of all protect lights coming on. You either have shorted out output transistors or powersupply mosfets transistors. This is mainly the cause of this all the time. Sometimes though it's not and you have to do further testing. With your amp, I don't know what was going on at the time of when it quit. The capacitor you speak of is fine it's just the protective shrink looks melted cause thats how it was done when amp was made. You need to test all output transistors and power supply mosfets with a digital volt meter set on diode check. Let me know what you find and itf you need help just opost a comment asking for my e-mail and I will taake you thru the steps. If this helps, please rate it so I can get out of this apprentice status.

When I turn the sound up and the bass hits hard the red light comes on

That is because your impedance is not correct. You probly have 4 ohm woofers wired in parallel. Try putting them in series. That will put your impedance to 8 ohms the amp will not clip, or go in protection that is what the red light means. Good luck

I have a EL 1500wat amp, when I turn it on the little lite comes on and stays yellow, it was green and was working,fine last night. Any ideas?

Look at fuses first. Then if they are ok. You need to check wiring. Ground. Power remote. If those are good. You need a tech.

Hey i dont know to much about amps, but me and my friend (he knows a decent amount about amps) would plug the power into the amp and the green light would come on. Though when we plug it into the subs, the...

Are you connecting positive to positive and negative to negative from the sub to the amp? If so, try positive to positve (+) in the far left channel and then the negative to negative (-) on the far left channel to. If no luck do the same in the other channel with one sub at a time. Try one sub at a time, Dont try an connect 2 or more subs to one channel as this would cause the amp to go into protect mode (red light you describe). Usually the positive wire has either a line down the wire, writting on it or has a red seperate wire with it when wire end stripped to connect it. Hope this helps and please rate...

I have 2 12" and

I suggest you get a meter that measure OHMS and check each speaker to be sure that they are showing the resistance that is listed on the speaker It could be between 8 and 4 OHMS If it is not then you have a bad speaker.

A red light appears within 30 sec. of being on. the more i tune it down the longer the green light will stay on. when its completely tuned down the light will stay green

yes you have a internal fault of the amp. the circuit that puts it into safe mode is bad and that is a very small chip on the board know as a op amp. needs to be repaired.

Got the hot nd ground conted nd the aux cables from the raido conted nd the amp does not turn on

The amp needs a remote signal to turn on. This is provided by wire from the back of your head unit. Also look for a 'REM' or 'remote' connection on the amp (besides the 12v and ground connection).

Look at the wiring/setup diagram for your head unit to determine which wire/connection you should use for this.

If the head unit does not have a specific 'remote' wire, you can usually use the power antenna wire to provide a turn on signal to the amp instead.

Rt 202 led light red and no sound

With the system turned off, disconnect the speaker wires from the amplifier. Turn on the system. If the light stays red, then the amplifier has an internal problem. If the light turns green, then your problem is a blown speaker, or a speaker wiring issue.
