i was wanting to know is what i will need to power 2 alpine mrv-1507rated at 1500 watts and a memphis 1000 d amp? will it require adding power caps and a extra battery or will the caps work ok with out the extra battery.
thanks
You will need to beef up your alternator, get a deep cycle dry cell battery ( Optima, Phoenix Gold or Stinger ) and get about 4 farads of capacitance . This will ensure that you will get power to the amps and also reduce the " strobe effect " on your lights.

yeah caps won't help much except to assist a larger alternator and deep-cycle battery (or array of batteries) which you really need.
the caps are for stiffening voltage rails only during brief, high currect demands, and won't replace an electrical system capable of powering that system.
they will (the caps) however, help with dimming headlights, latency due to the amps needing power quickly and not having to get it from the alternator, etc.. but again they only store current and release it for brief instances.
all of the above, plus a good fused, distributed 1/0 gauge power cable setup with proper terminals, fuse and distro blocks, etc are what you need. you'll be looking at around $500-1000+ for the power distro setup all said and done if its a good setup.
that's the average I've come up with on ones I've done, but it's well worth the effort and cost.
