Hey,
i have a small Pyle PLAD212 amplifier in my house wired to a Pioneer TS-W257D2 in a sealed box.. Yes i know its a small system but it add alot of bass to my old sound system. Now the problem is to convert to AC to DC i use a small car battery charger (6A Max) and the fuse on the amplifier its a 15A.. So i asume that the amplifier use 14-15A for max power. When its at high volume i got many distortion (Voltage drop) so if i add a capacitor? The energy source is unlimited no? Come from a normal plug in the wall.

A cap won't help if your power source can't keep up with your system.  It's exactly the same as running a large system in a car with a stock alternator. 

What you should get is a proper 12V power supply,  You can get one that can supply a constant 20A for under $100

Life moves pretty fast; if you don't stop and look around once in a while; you could miss it.

What is best? PSU In parallel or constant supply? But is a car battery charger is good? I see many of them, there some automatic and manual... I think manual is the one i want no?

You need a power supply rated at least 15A. End of story. Battery chargers are not filtered or regulated, so I advise strongly against those. Get a proper power supply.
Here's a minimum...
But this one will be even better...
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I say don't be foolish, buy an amp designed to plug into the wall.  Here's a nice cheap solution.
