In theory, capacitors store power during intervals when it is not required, which is most of the time, and release it when momentary peak demand exceeds what is available from the car's power system. Btw, on the link you posted it directly states: "Requires 4-gauge power and ground leads and 80 amp fuse" |

New member Username: 2fast4y0uPost Number: 3 Registered: Nov-09 | alright sorry for all the questions that may seem done i know nothing. So at 1000rms the 4 guage wire and stock everything (other than headunit) should hold up right? Don't need a good battery or anything else? and ditch the cap. I'll take the recommendation - so what he's saying is the system will drawl more energy when it's only drawling a small amount but when it does drawl the large amount my headlights will dim right? bc the system can't supply all the electrical with the total ammount of electricity that i needs. So what's your opnino on this then? Just figuring I would ask everyone - i know nothing and thank you all for your time!! |

New member Username: Creator1Canada Post Number: 8 Registered: Nov-09 | Go to a Princess Auto, Pep Boys, Welding shop- Praxair, etc and buy a chunk of 1/0 or 2/0 cable! THE BIGGER THE BETTER! And u'll need ANL or Wafer fuses to handle 100 amp or higher- name brand fuses this big can run $25 bucks a piece! AS ur voltage drops, the amp draw will increase until u pop fuses. FOR each $25 dollar fuse- think how much the money spent initally on the biggest cable, with save u in the long run.So- spend the cash and get the LARGEST cable u can. Welding cable is the BEST elec cable for passing HUGE amounts of current and its WAY more affordable than esoteric brands that have pretty colored jackets. Also- its very flexible cuz of the hi number of strands so its easy to run inside the vehicle. DONT get a big gauge of home stuff etc cuz they have the least # of strands and are like tow cable u have to kink to bend!  NO cap. Need to ensure ur battery is fresh and has a good res time and hi crank is better. I use 250 amp manual circuit breakers for my Show truk. That way, I can open the breakers IF I have to charge the 3 batts before a show and the charge current doesnt flow thru my amps while its connected. Also- manual are better cuz u have control if it opens- it doesnt auto re-set and keep smacking the hell outta ur subs. I found them on E-bay from a company in China for $6.95 each! THEY are the SAME as the Phoenix Gold breakers for $120 bucks each! Same little Red lever and everything! |

Gold Member Username: Hittin1TEAM REVOLUTION, La. Lake Charles... Post Number: 4139 Registered: May-07 | Thanks big DAve... How are you determining what size wire and fusing is needed? So, If i get that chunk of 0/1 ga. power wire, what amp fuse do I need? Is that fuse there to protect my amps?What other electrical upgrades do i need if I don't need a cap? When would I need to put another inline fuse in this system? Thanks.. any help is appr'ed |
