i have DK2-1000 watt amp i keep blowing the fuses on the amp, i bought a new car battery that is 850 cold cranking amps instead of 650. my fuses didnt blow for a couple hours but then the battery drained and the fuses blew (volt meter on dash would drop to like 10) so my theory is that if the battery drains the alternator sends power directly to what needs it (my amp) blowing my fuses. the alternator should be 80A output. I am running 8 gauge ground wire and 4 gauge power wire to my amp. do you think the 8 gauge wire is to small and not letting enough power flow back to the battery?

You should connect a capacitor before your amp which will protect the amp from current peaks that blow the fuses. Also and very important connect a fuse power block after the battery positive terminal, beacuse if there's something bad with you alternator of your battery overheat, etc, the fuse will prevent the excess current to flow to your amp,ergo it wont blow the amp's fuses.

Your power wire is only letting as much power in as the ground is allowing out. Yes, keep them the same size, grounds can be bigger just not power wires.
Capacitors DO NOT work. Alternators produce power. Batteries don't produce power. Capacitors don't produce power. ONLY alternators produce power.
Caps are only good for power 'bursts', if you will, of -UP TO- .01 volts. So no matter how many farads you have(500,000 even), they are worthless.
Adding extra batteries and caps actually hurt your alt if it can't charge them quickly enough. And will fry it.
DO NOT buy a crap, I mean, cap. Instead, do the Big3 Upgrade (power -charge- wire from alternator to battery, ground wire from batt. to frame, and ground wire from frame to engine block) all in 4g or bigger wire.
Do this and it will do what people claim caps do (which DON"T, don't waste your money!), headlight dimming, etc, gone! Really!
I do have a capacitor. I thought it helped when really it made my alt. start to whine (trying to charge too many things).
My dimming problems went away, my ground noise (the Big3 eliminates the need for noise filters (which are crap, too) went away(not b/c of cap), but only after doing the Big3 Upgrade.
DON'T WASTE YOUR MONEY!
Good Luck!

Both power wires (ground and hot) must be the same size. The whole system is only good as the weakest link and that 8 AWG wire is it. What you do to one side you should do to the other or there's an imbalance.

thats a possibility, but your best bet would be to just go all out and get a power capacitor that will store extra energy for you and that should stop the problem, they tipically run between 120-250 bucks depending on how big of one u want
