how much ?
 

ok mow much you guys think it would be to get a box a cap and a kappa perfect 12.1d

and do i realy need a cap i know some people that use them and some that dont

also for the money does ne1 know of a better sub than the 12.1d's i havent sen one but i dont know everything

A cap basically stores power so when your system hits it'll drain from the cap before your battery helping your lights to not dim. You should use 1 farad per 1000watts. When I had my 1500watt rms system I never had a cap but it wouldn't have hurt. Prices on caps are usually around $150-$200 for 1 farad, a box can range depending on type, thickness, material made, etc and that sub I believe retails for around $500? I think.

I was thinkin of a different sub for that price. check this out http://thetechzone.dealtime.com/xPC-...a_Perfect_12_1

thanks for the chart i have a hifonics zx6400 which is rated a 2 by 350 rms and 4 by 85 rms. it doesnt give peak but i figure its about 1400 what did you ahve hooked up to that 1500 watt amp cause i realy dont want to buy a cap

you can find a 1.5 farad cap on ebay for like 60 bucks, i should know i just bought one
