what size alternator to buy?

about how many amps of an alternator do i need for a 2k system?

system is a little under 2thousand, but rounding off. currently stock battery and alternator.

would one 1400 kinetic battery for system and car do it? i wont always be pulling this much power, but just want to have it as back up and in case.

Anything above 2kW, we recommend a 250A alt (160A+ at idle). If you will be using 1400's I beleive they would recommend at least two... or a single HC2000. You may want to look into a single D3400 and save yourself some cash...

A hc2000 would prob be your best bet..is that in conjunction with a main? Will you be running any highs or mids? Ive seen people run 1k-1500 off like stock 140 amp alts..so I wouldnt think youd need more than a 200a alt.

the 2k includes the mids and highs. =)

not trying to run a real high end system, just an okay daily set up.

running about 200 watts for my mids/highs amp and 1500 for a single sub setup.

il look into the hc2000, its just that my stock battery holder under the hood is pretty **** small, i dont think it can house anything bigger than the size of an hc1400 and i didnt want to have to make another run of 0 gauge to the trunk to get an extra battery in parallel.

what brand is the d3400?

okay, so about a 250 amp ho alternator for about 2 thousand watts would be good then?

what kind of battery now? just read some threads on batteries and theres a good range to go for. deep cycle and not deep cycle. not sure which would be right for my system. kinetik, optima, stinger or the powermaster like someone in this thread told me about? any suggestions on brands and models for my use?

just looking for one battery to run everything (if possible) i think il rarely be pulling even into the 1500 watts from my audio system and only when engine is running. not looking into something that can last when car is off, but also something that wont die when i leave my doors open for even a little bit like my current batter. =(
