Hey there...
I have had the system installed for 4 months now....i have problems with the sound from my rear speakers....on increase of the volume the sound gets sligtly distorted and there is a rattling sound...as if the signal is comin through properly from the amp....but its really slight...its not that the speakers are not taking the load....i thik there is a wiring problem i cant seem to figure it out....i have just tightened all the connections again...and sometimes the sound dissconnects as well and althought the amp is on...the sound does get cut on n off.. Please help me with any adive and what connections to check if there are any...thanks

Explain on what you have a little bit more.. are your rear speakers amplified? If so, are you running the high-pass filter on the amp, or full? If full, try swtiching it to high pass, if you have subwoofers. If they are not amplified, try putting 'bass-blockers' on the speakers to rid them of any bass that may be going to them, and that will help with distortion at higher volumes...

Hummmm, at first blush, rattles are usually mechanical in nature. Either a speaker is about to go out or you have something loose back there... maybe sitting on the speaker cone and it is making that noise.
When sound is cutting out, that often means a few possible issues:
1. Loose input wires to amp (RCA's, Power, Ground or REM)
2. Amp can go into protect and still be on (thermal or short protection)
3. Loose wire at speaker terminals (not terminals, tinsel leads to Vcoil)
4. Something wrong with that speaker
Do you have a walkman or other audio player you can plug into that amp and just listen to the rear speakers? This will help isolate part of the problems noted. If the amp or speakers cut out, check the amp for heat issues. If the amp feels very warm, thermal protect circuits may be activating... waits a few minutes and then the amp comes back on... you may have gain settings to adjust. Most amp gains do well at ~2 volt settings. If the gains are set much lower than 1 volt, the amp can easily be overdriven and go into thermal protect mode.
These speakers you have now, how are they mounted and do they have wire mesh screens that snap in to a plastic speaker mount? If yes, the screens can come loose as the heat up/cool down and work loose. Check that if you have this style of speaker mount for rattles.
Finally, is the amp mounted securely so that it will not move around while driving? If not secured to a fixed object, the amp can shift about as you drive and cause electrical connects to come loose.

PS Try these items for starters. If nothing unusual is found, have to dig a bit deeper into the install. What amp and speakers are used here?

REMOVE THE MAIN POWER FUSE BEFORE REMOVING THE GROUND. INSTALL NEW GROUND TO BARE METAL AND THEN REINSTALL THE FUSE !!!
