i need to run 2 batteries on my ford focus coz just 1 battery dies wen i put my amps on

First, get the best 2 batteries you can fit in as close together as possible. You need a real heavy gage cable running between the two positive terminals. Ground both negative terminals to really good metal frame bolts. I would put a heavy cut out switch on the extra battery so you can run only one battery if you want. This may keep you from getting stranded if you are in a remote area listening to your tunes with the engine off for a long time.
 
Buy a better battery first off, maybe something like a deep cycle battery that has a high amperage rating. Also make sure you have a big enough alternator. You could also add a supplemental battery in the trunk and wire it in parallel to the primary battery. Make sure it is clamped down well.
 
i agree with the above or try to get more amperage. or getting a better battery because your hood on a focus looks pretty cramped for two.
