*2/Batteries[Yes & No]*
big grounds and id recommend 2 bateries
******************^^^^^^^^^^^^^^^^^*******************
Hello/
I know this is an *Old Post*/
but,the Thread Starter would not really need 2/Batteries,unless he wants to listen to the System *With Key-Off*.A *Battery Solenoid or Relay*[Same Thing] should be used to eliminate draining *Both Batteries*.It goes *In Between both the Car Battery [For Normal EveryDay Use] and the Stereo System Battery [For those Key-Off Listening
Moments/
].It seperates one from the other in the Key-Off [*Accessory* Side of Ignition Switch]from Main Battery.
When you start the car,It opens up the Relay to let the Alternator charge *Both Batteries*.Your 200/Amp Alternator should be Fine for your Car & Stereo System.As one other Poster said,to do the Power & Ground Upgrades
under the hood.Do it Once and *Do It Right*/
.MOPO,is to use *All* 1/0 Gauge Flexible Cable for Your:
1]Alternator to Battery Positive
2]Battery Ground to Chassis Frame
3]Engine Ground to Frame
********I cannot stress enough to Please:********
1]*Crimp and/or Solder ALL CONNECTIONS* [With the Proper Tools]
2]*Use Adhesive Dual Wall Shrink Tubing* over all connections:
A]Red for Positive B]Black for Negative or Ground
When you heat that shrink tube,it activates and inner adhesive glue that flows around the connection,and outside the ends of the tubing.Once it cools,you have a waterproof and safe connection.
*Remember*,that those cables are out in the Elements,and in time,if not properly done can raise hell with:corrosion/water/vibration/etc.
Use Quality Cable Ties,and route the Cables *Neatly and Safely*.You should [Your Option,of course] also use Wire Loom or Expandable Sleeving to protect the Cables,from abrasion/corners and other things.And it dresses up the Engine Bay,too.
Another poster said to use the same thickness cables to your amps,as you did under the hood.On some amps,that may be possible,but on other amps,they may not have the terminals to use 1/0 Cable for Power & Ground.
You can only fit the Cable to the Terminals your Amp provides.
Sorry for the Long Winded Response,but it's just some things *I do* when Upgrading Cables for an Aftermarket Stereo System in my cars/
.
It takes *Time & Patience* to do this type of work.*DO NOT RUSH* to get it
done,'cause,in the long run,it sukks to take short cuts/
....Take Care.
