power distribution block

I am still learning as i go in the field of mobile electronics, but i have yet to install a distribution block. Today was the first try, but i seem to get lots of interference, im running the power and sound wires seprate yet i have lots of feedback in my syatem, is there any special way they are supposed to be installed? becuase i ran 4 guage from the battery to the distribution block and from the block it has two 8 guage outputs which im runing one to each amp, now there are two holes on the 4 guage side like an imput one and two on the sides, so one on the top and two side holes like a right one and a left one, so im I supposed to do somethhing with them? please somebody lead me in the right direction, thanks

I'm not an expert, but...I don't think your problem is the power distribution block or the unused power distribution block output slots. Remember, there's no "in-only" or "out-only" slots in a power distribution block, although you should have only one "power input" wire for a power distribution block.

Your problem may be how you've grounded multiple components...you don't mention if you've used a power distribution block to combine multiple 8 guage ground wires back into one 4 guage ground cable (total length preferrably less than 3 feet) that ultimately leads to a good common ground location.

Is this installation in a Ford Mustang?

no, its a neon, but I should use 2 distribution blocks? one for power and one for ground?

Sure...use two power distrubtion blocks if you want your install to look nice and organized. In this case one distribution block would use as its input the single power cable from the battery (the two outputs would supply your amps with + current); the second distribution block would use multiple ground inputs from your amps and a single heavy guage ground cable output). I hope we're communicating on this subject...in other words, my understanding of the term "power distribution block" is a piece of hardware that simply distributes an electronic current flow from one (usually lower gauge (thicker)) cable to several (usually higher guage (thinner)) cables, or in the reverse case, a number grounding cables into one larger "master ground" cable. Alternatively, you could simply hook both of your amps directly to the battery and both of the ground cables directly to a ground point.

I have a multipe amp system in my car...I use a

For instance, I use two of these in my system (see link below)...I'm also using two capacitors, so the power distribution blocks make it much easier to manage all those heavy guage cables.
