Ok guys, I have two Bazooka ELA500.1 and Two Pioneer Premier SPL series, Which im using one amp to each subs at 2 ohms 500w RMS (my amp is 2 ohms Stable),.
Bazooka amp have one pair of Imput and One output which in the mannual says that you can connect one rca in the output to connect another amp, so I did it that way, Im running only one rca to my crossover and one rca from one amp (rca output) to the other imput of the rca.
I was listening to one son from outkast (the way you move) which have a really good bass, And One get into Protection mode. Yesterday, the one amp get in to protection mode but the other no, Is either one or the other one.
I checked Ground.. And Im thinking it might be the Rca going from the output from the amp to the Imput of the other amp. Do you guys think it could be that>>. Or what else should i check..
thank you for your help

I've read about 15 reviews on this amp and almost all of them mentioned the amp overheating. You can purchase Bazookas cooling system but I would just get one amp that can handle both of your premeir subs like the Rockford Power 1000bd. This amp bridged in 2 ohms would output 500 watts to each of your subs. This is a really good amp that is underated. I think it would push your subs alot better. Just wire your subs to the mono output of the Power 1000bd like this : Heres a link to Crutchfield which has prices that are usually the same or better then your local dealer. https://www.crutchfield.com/cgi-bin/S-Zj5lqu5APCX/ProdView.asp?s=0&c=3&g=130&I=5751001BD&o=m&a=0&cc=01&avf=N

what guage power cable did you run from the battery?? Is it a long run?? how long is your ground wire?? Do you have a good ground to the amps(directly to clean metal ,no paint, straight to the body)? Check the amps voltage when problem happens see if you have a big voltage drop this may be causing the amp to overheat sending it in protection mode.

Im running two gauge Rockford fostage flat wire from the battery to the trunk, then it goes to a distribution block which im using 4 gauge going to the amps. the voltage is arround 13.4, so im getting good voltage, What im thinking is the way i wire the capacitor.. Each amp have one capacitor, the way i did it was, ground metal to the - of the capacitor, - from the capacitor to the amp. what im going to do tomoorow, is - from the capacitor to ground and amp ground to the same spot as the capacitor... to see if something changes, I try with another amp same model , same thing happems. I bought new monster cable RCA , which i spend like $80,,
and i dont know what else could it be the problem..

OK, an amp going into protection mode probably has nothing to do with the power to the amp, unless it is going too low. If you are staying around 13 volts, your power supply is probably fine. First check your subs. Swap the connections so the amps are powering the opposite sub and see if the problem moves. If it does, there is something wrong with your sub or your speaker wire. You say you are daisy-chaining the second amp off the output from the first one, and it is the second that is shutting down? Make sure the RCA cable from the first amp to the second one is OK and connected properly. You say you have a cap for each amp, but the way you say you have them connected is strange. It should be the + on the cap to the + (main power from the battery) on the amp, and the - on the cap to ground. The amplifier ground can be the same location as the cap, but a different location is often cleaner.

Yes, It was wear, the mannual say that way, My old Capacitor the way i wire was positive from the battery to the cap and from the cap to the amp and negative from the cap to ground(metal) and amp to the same spot in the chassis,,.. I will do that tomorrow,, to see if anything changes... Because it have to do something with that, because when it goes into protection mode, the amp is not hot at all.....
and both amps goes into protection mode.....

and what did you say about the subs... my subs are Dual 4 ohms, Which can be wire into 2 ohms or 8 ohms, I did it at 2 ohms...
positive of one coil to positive of the other coil and to the amp, same with the negative...

how far i sthe ground from the cap to the amp?

less than 3 ft

your subs should work fine the way you wired them ,best thing is try what you are going to and see what happens and post back. good luck! i am not familiar with thse amps but maybe they are not that stable at 2 ohms.,like they claim.
Posted By: Sebastian018

They are MOno, One Channel 2 ohms stable....
But I will see what happens tomorrow..
thank you guys

maybe you should do a series parralel configuratin on the subs to see what happens!
Posted By: mobiletoys2002
Date Posted: January 25, 2004 at 12:02 AM
a series parralel configuration will give you a higher impedance to the amp.Thi smay solve your problem!

You mean do it at 8ohms???
Posted By: mobiletoys2002
Date Posted: January 25, 2004 at 12:12 AM
no!that would be series wiring a series /parralel is a combination opf both series and paralell that give syou less tahn 8 ohms but more than 2! It may still hit really hard.

SO HOw DO i Wire it.... HOw do I have to do it..

when an amp is wired mono it sees half the impedance of the sub for instince if you have it wired in paralel the coils make 2 ohms but the amp sees 1.

First try what you want to then get back to the forumm post your results and then if it dont work try this.I'll post it when i get the diagram ready.

OK, But Im saying how do i have to wire, i know is in parallel but how From where to where..
thank you

You may have an issue with power wires running to the amp or a bad sub or subs.You may want to clear up thast issue first or at least find out what is going on.
Posted By: Sebastian018
Date Posted: January 25, 2004 at 12:20 AM
OK, I will do that tomorrow.........
the subs are new!!! Brand new package sealed....

my bad you are running one sub to each amp right? If so that is fine leave it like that>I was thinking something else

Does this only happen at high volume levels?
Posted By: Sebastian018
Date Posted: January 25, 2004 at 12:37 AM
No, I was listening at low volumen, then i turn it a little bit higher and it went into protection mode....

So your subs are 2 ohm dvc? If they are then you cant get a 2 ohm impedance from each one if you wire them to their own amp. You can only get either a 4 ohm load or a 1 ohm load like this:  Tell me if this is what you are doing.
Posted By: Sebastian018
Date Posted: January 25, 2004 at 10:58 AM
NO My subs are dual 4ohms DVC< It can only be wire into 2ohms or 4 ohms..

and They way i have is like this

well they way i did it was positive of one coil to positive of the other coild and to the amp same with the negative..(2 ohms)

OK, GUYS< I took everything out ( i have a custom instalation( so it took me like 3 hours to take it out so i can change the grounds... I did changed BUT STILL THE SAME PROBLEM< I WAS LIKE HOW COME< 4 HOURS FOR Nothing.. Them I star thinking what else could it be, and I just got last week the AUdio Processor pioneer DEQ-9200 and it was in PRO Mode, so i star reading the mannual and i change two seetings , one intead of the bass to be stereo i select mono, and The setting of the bass was really high like at 6, so i put in at 4 and i did some other changes i tested, and It seems to work, because before like after 5 minutes it went to protection, now i did it for 10 minutes nothing happens, so i think that was the problem i will check out again for more than 10 minutes...
thank you for your help...

Why didn't you say you had other things in the signal path? Sounds like your gains are whacked. If yu want it to be right, set everything to minimum and setup your amps to accept the proper input levels you are sending them. If you don't know how to do this, there are lots of resources in these forums and on the web. Search fo "amplifier gain setup."
