need more juice!!

Ok, i think i have about overdone my system, my question now is should i get a high output alternator,    cap (s?) or add a second battery.

I have a  gmc p/u with a clarion HU with the  motorized monitor (just watching TV alone seems to kill the battery quickly) I recently upgraded  everything else. i  now have

punch 500 amp running 3 phosgate 10"                                                                                                            legacy 600watt amp running  2 10" subs                                                                                                               xtant 4 channel amp running (2) 4x6 and (2) 4"infinitly

this alone when its cranked up dims the lights and the volt gauge drops off alot. In the summer I will be pulling a boat so i will be adding trailer lights and fog lights to my total pull on my system..

So what do you think..what would  help the most? 2nd battery, cap( how many/what size), a high output alternator, (i will do all if needed, or I just dont what I should do).... thanks..

go with a HO alternator...caps are not near as good as what most salesman claim for helping your system...a 2nd battery will help for now, but when you start adding the other things you are talking about, that just creates more work for your alternator...and it sounds like it isnt keeping up as is...

if you get a big enough HO alt, you wont need a 2nd battery or *ugh* caps...

if you wont a greater explanation as to why caps are bad, ask for it...I will leave you with that for now...

dont know if this pic will show up, does anyone know where to get a good dual battery set up? or have any suggestions?

how extensively do you plan on playing your stereo without your truck running?

as far as adding a battery, if you dont have room in the engine bay, it would probably be best mounted in the box close to the cab, fastened securely and out of the weather...buy a marine battery box or something similar that is weatherproof and bolt it to through the box to something sturdy...

but a second battery is really only necessary if you plan on playing your stereo alot without the vehicle running...one idea is to run a second battery but isolate one, so you will never be stuck somewhere and not be able to start your vehicle...I have 2 batteries in my car, but they run together...no isolation...

one other note: I wouldnt bother going out and buying the Yellow Tops or Red Tops if that is what you are thinking...Stinger batteries are all fine and dandy, but the company that actually makes Stingers competition batteries is Hawker Oddysey and they are exactly the same batteries for alot less money...and that is if you want fancy batteries...if not, the Sears DieHard Gold batteries are very underrated and well worth buying, especially considering the savings over a yellow or red top...
