Audio Systems: amp preferance, ohm model, guage wire


Question
-------------------------
I appreciate your patience.  I really have no clue about any of this equipment and what it will do or how it works.  I appologize for bieng so undescriptive in earlier questions.  

What I would like to do is have a clear, quality sound that still sounds good when its turned up and good amount of bass but nothing that will break the glass, just sound good.  I would like to install an amp to supply power to my dash and door speakers as well as a sub.  I went to a website and answered some questions and they gave me some preferences:

KENWOOD 'KAC-8452' 4 CH. Amplifier
Kenwood 'KFC-W300S' 12" Subwoofer
PIONEER 'TS-G4640R' 4" x 6" dash
PIONEER 'TS-G1610R 6.5" door

I have already installed a KENWOOD KDC-1028 50x4 stereo less than a month ago.  

Hopefully this is enough to see if I'm on the right track.  Thanks agian.

Answer
I cannot see all of the connections ect on this gear online.
There should be ample instructions included explaining how to bridge the two rear channels for the sub. I would use an 8 Ohm model which would be applying 4 ohms to each of the rear channels in bridged mode providing dynamic, safe and reliable operation.
There should be instructions for all of that new gear.
Thew amp is right in the ballpark for power or 100x4 RMS.

You will need to go to Walmart ect and get a power wire installation kit. Get one that uses a 4 guage wire from the battery to a distribution block near the amp where you can attach some 8 gauge power wire to the amp. Use at least 8 gauge to ground it.
Again, you will be not using any of the deck power after this amp is installed. Its' 50x4 is handy in a pinch but you will be happy to be bypassing those.

Start with some paper and draw out a few diagrams including:
Battery
Ground point for the amp and deck.
Headunit.
Speakers and wire.
Line Level connections/wires (rca)
Kicker or remote wire (from the deck to the amp to turn it on).
Powerwires and fuses/distribution blocks.

I usually use an overhead view to keep it simple.


Use the instructions while considering the guidelines I emailed earlier and you should be ok.
