Sound System cutting in and out!!

I bought my car with an aftermarket sound system (dual 12" 400 watt rms pioneer's with front splits running off pioneer 600 watt max power 4 channel), and it all ran fine, except i realized i wasn't getting nearly enough bass as i could.

So recently i bought a Alpine 1000 watt rms monoblock to power my subs and bought new 6.5" s-types for the front doors (left them on the pioneer amp).
I got it all professionally installed and it seemed to work well for a little while but then it started cutting out.
Sometimes it just cuts the fronts out and then the subs might cut out or it all cuts out and comes back after a bit.
I've noticed it works better when i have it in neutral or when i change gears the bass comes back and when i put it back in gear it cuts out again when the revs obviously jump back up.

Could it be an alternator issue?

How do i fix this?

cheers Henbo

Well if your sounds are cutting in and out it could be a couple of diffrent things. for 1 your amp could not be powerful enough, for two ur power wire might be too thin or not powerful enough to push the right amount of energy current from battery to the amp and speakers. Also your battery may not be strong enough there are certain batteries u can get when having sounds.Also your ground wire might not be in an stable place. without out that the speakers will not work..Or u may have altenator problems. wish i could have ur car for a day i could definatly figure out the problem..you should take it to a shop..

This is caused by one of two things:
1. the gain on your amps is improperly set and causing the amps to clip, which sends them into protection mode causing the sound to cut out.
2. a lack of current is causing the amps to clip and go into protection mode.

solutions:
if problem 1, set the gains right, as so:

if 2. you need to do the 'big 3' upgrade and probably install a larger alternator in the car.
