get an uprated altenator, then battery then cap if needed - that's the best order to do it in to see noticable effects.

you would be a lot better off spending your money on an upgraded altenator, cos if the power isnt htere in the first place, a cap will make almost no difference at all. I think you can even get your current ones rewound.

A new alterneator could cost a fortune

but if the powers not there in the first place, the lights will still dim.
I have an uprated front battery, an optima yellow top and a cap and still on big bass notes the lights will dim, and thats with about £350-£400 of stuff trying to sort the power out. Now i know it would have been a much better idea to spend that on a bigger alternator.

Ditto that...
I've got a 1.2 farad cap, and to be quite honest it's pointless really without the power behind it in the first place as Richie's said...

How much would a bigger alternater be as i get a fair amount of light dimming with just one amp and one sub.

What alt are you currently running and whats your engine? Usually a better quality larger capacity battery will give you less dimming and longer running time, as well as being able to take some stick!
