yea guys, the screem came from all 4 of my mids and highs speakers when i turn on and off my system. The speakers are two powerbass and two BLT 5s. I connected all 4 speakers in both methods (series and parallel) and got the same loud result..
Wat can be causing this loud screem to keep occuring ?
Could it be the channels on the amp ?

Do you hear the sound briefly when turning On/Off...? Or how long does it last...? Do you hear it when the volume is turned all the way down...? Has the sound been present since the installation of speakers,amp,or both? Does it do it everytime...? Go ahead and list amp and stereo too...

Did you conect your amp(s) remote terminal to the amp remote wire of the deck? What happens if you leave the radio turned on and just disconnect that wire. Then reconnect it, does it still make that noise.

yea i did all that. i connected the remote wire from the amp to the amp wire on the deck and got the same crap. i was thinking the channels on the amp can be repaired or replace, maybe that can work

With the radio turned on, disconnect the remote wire from the back of the radio, listen for the noise, then reconnect the wire. Listen for the noise again, did you hear it after either of the 2 above processes?

After reading your last post, I really do not know if you tried what I suggested, or if you are just telling me what you think it would do.
I am trying to figure out if the noise is being generated by the deck or the amp. Please clear up whether or not you actually disconnected the wire and reconnected it with the radio remaining on.

I did what you told me to do u kno.I tried all ways to slove this crap and nothing seems to be working. My instincts are telling me that its the channels on the amp are damaged or malfunctioning.

When you did what I suggested, did you hear the noise when you disconnected the wire? Did you hear the noise when you reconnected the wire? Please answer both questions.

when i disconnected the wire i didnt hear nothing..and the same goes to reconnecting the wire....u wouldnt hear the screem when the wire is connected to the deck because the screem only happens when i switch on and off the system...the only way i can solve this situation, is if i connect the remote wire on the amp, straight to the battery, but when am switching off the unit, i must take out the remote wire off the (+) pole, to prevent the screem.

Your amp is not the cause of this problem. The problem has to be the fact that the amp is turning on before the radio settles down. And it is not turning off immediately at radio shut down. Every decent amp out there has a turn on delay to avoid problems like the one you are having. You can install a switch on the remote wire that you can trurn on after the radio powers up, and then turn the switch off before you turn the radio off.
Did you connect the remote wire of the amp to the Red wire of the radio or to the radio's blue/white wire?
