Ok i am going to this show in a month to challenge the brand fusion to a sound off.

I just had a few questions for a pro perferably on the wiring of the system.

I am going to have 3 amps and 2 caps.

The caps are both 1.5 dig fared, and the amps are: 1) 1250 (2500 dymanic) watts mono block and it has 2 40 amps fuses on it 2) 900 watt mono block it has 2 40 amp fuses and 3) is a 50 watt x 4 channel which has 2 25 amp fuses.

so far i think the wiring is going to be:

battery-----fuse-----------------cap1---cap2----------dist block(with fuses 2, 40 1, 25)---amp1,2,3
( caps wired in series, so all amps can use)

I was wondering what amp rated fuse should i use next to the battery and what gauge wiring should i use from the battery to the fuse to the caps and dist block.

I also have an svr comp battery.



What you guys think??

maybe you could tell us what the whole setup is. , and if by sound off you mean loudness, or sounding better.

it is going to be a sq and spl comp, but i am going for sq personally.

the setup is a svr-50 battery a panasonic cq-dxf501u head unit.

2 fusion 1.5 dig fared caps.
50 x 4 chan fusion powerplant amp, powering boston acoustics fx6 and fs50 interior speakers

fusion powerplant 900 watt mono block powering 2 12" fusion poweplant 900 watt subs

and a fusion jonah lomu 1250 (2500 dymanic) watt mono block amp powering 2 fusion jonah lomu 12" 1250 watt subs

that good?

heres the problem. having 2 different kinds of subwoofers and 2 different kinds of amp in there (2 powerplants and 2 jonah lomu's) is gonna cause massive massive cancellation. what that means is your sq is gonna suffer horribly, and your spl scores are gonna be really weird (one note will be real loud, another would be really really low)

also, caps are completely useless for spl, they bring your score down... and unless youve got something like at least 30 or 40 farads, theyre no good for sq either

to answer your original question if you really do wanna keep that setup, youd prolly need an 80 amp fuse on each of the mono amps and a 30 on teh one powering the interiors. so at teh battery a 200 amp fuse would be fine

i have a bass controller for the 2 powerplant subs cuase twhen i go for spl the jonahs will be on and when i go for sq it will be all powerplants. there are 2 powerplant amps and only one jonah amp

who makes a good 200 amp fuse for at the battery and is the 2 40's and one 25 in the dist block ok? also i was wondering will haveing a big 200 amp fuse like that at the battery drain it anymore.

and what gauge wire should i use from the battery to the caps cause from the caps to the amps is going to be 4 gauge and speaker wire should be like a 12 right?

i just rememebred is it ok to just hook up the caps one after another in line and then charge them with the car

 
Rep Power: 0

so youre gonna turn one set of subs off for spl, then turn the other set on for sq?
that would probably fix your cancellation problem

use 1/0 gauge wire for that much power

fuses dont drain power.

the 40 amp fuses will blow in teh distro block. if the amps got 2 40 amp fuses in it, your distro block fuse should be the sum of those. the fuse will pop

a fuse is a fuse is a fuse. if anyone tells you one brand makes a better fuse than another brand, hit them for being stupid or for trying to con you.

12 gauge speaker wire is fine

ok so this setup should work then....


battery to 200 amp fuse is 1/0 gauge from the fuse to the first cap is 0/1 gauge with little clamp on the end to connect to the cap then from the first cap to second cap is 1/0 gauge and then from the second cap to the dist block is 0/1 gauge then from the dist block to the 3 amps is 4 gauge


what about charging the caps for the first time

you shouldnt waste airspace on the lower end subs..you should probly just build the box as huge as possible for one or two of the 12s with a bunch of port. i have a box that will fit in our cars...face is built for one 15 though and u cant have a back seat. and u need to take out both seats and the center console to get it in....oh...and unbolt the Ebrake also.....but your more than welcome to use it.

the subs are awseom for both spl and sq. thats why i have all four, and plus subs are made for different purposes. its not all about how loud you can thump. if you can't hear the different tones its just a waste of money. thats why there is more money in the sq competitions than in spl

as to the cap question, i dont believe in caps, nor do i support their usage in any way, shape, or form, so i dont tell people how to use them =)
basically, i think its one of the biggest marketing lies in the history of the electronics world

hmmm...more in SQ than SPL....i dont know about all that....the truck me and 2 buddies built cost a pretty penny..lets add it up

1994 toyata truck - $2500

2 inch windows- $1700 plus metal to make the fram

enuff 2 inch box steel to remake the floor of the bed and brace the box- $900

2"x2"x32" copper buss bars - $600

3 300 amp alternators - $900

2 custom built 18's - $1800

spare parts to rebuild 18's - $700

68 bags of quick crete - $700

16 sixteen volt batteries - $5500

16 Rockford BD1500's @ dealer cost - $8800

6 spools of 2/0 wire - $770

8 spools of 1/0 - $640

airbag setup and gusset for the rear axle cause the truck weights 12k now - $1000

1 gallon fuel cell cause we had to cut out the gas tank and make the 4wd truck front drive only to make room for batteries - $200

3 guys, working 8-16 hours a day for 4 months - who knows the cost on that labor.

A little over $26,000 thats just what i could remember....i didnt add in Rebar, welding supplys the 1/2 inch aluminum and 13 ply birch wood used for the baffel, the podium we built, the swinging amp rack, all the connectors used. i know SQ guys spend alot but this system was for only 2 woofers...Imagine how many more amps, batteries, alternators you would need for an 8 woofer, or a 12 woofer car?? there is a ton of money in SPL

dam, thats alot

how can u have 3 alternators in a car?

i was talking about more prize money in sq

anyways Ludlam do you think this works:
battery to 200 amp fuse is 1/0 gauge from the fuse to the first cap is 0/1 gauge with little clamp on the end to connect to the cap then from the first cap to second cap is 1/0 gauge and then from the second cap to the dist block is 0/1 gauge then from the dist block to the 3 amps is 4 gauge

also does anyone know about the cap question

oh final thing i can think of whats the difference betwen the inline fuse and circut breakers and are fuses still better to have becasue i am going to have the either the inline or the breaker next to the battery as well as the 3 fuses in the dist block

 
Rep Power: 331

breakers and fuses do the same thing, fuses are oh so cheaper, but if you blow em a lot go breaker.

as to charging caps use a test light in between the battery lead and the cap + terminal. or a 12V light of any type will work. light goes out or gets dim = little current = charging done. people say to put it on and leave it for like 5 minutes, but the fact is in electronics stuff goes by instantly, the transient response would likely be minimal after about 2 seconds with just a normal resistor in place (like 50 ohms).

 
Rep Power: 0

but will charging 2 caps at the same time be bad for our car? and i have heard that breakers are not as reliable as straight up inline fuses and that sometimes they don't blow when they need to and when you need them to they don't is this true? and lastly what about the connecters on the breakers they look a little cheap to me its like a star nut and a screw sorry about all the questions but i am ordering a crap load of stuff to get ready for this show

ludlam did my setup the way i wrote it a few posts ago seem good?

 
Rep Power: 339

breakers are less reliable. you can charge 2 caps at the same time...it will just take twice as long. prize money is SQ....how much is it? my buddy worked at the IASCA finals and there were like 30-40 cars there...seems like a joke.

 
Rep Power: 0

prizes totaly depend on how many cars show up usually how much less reliable are they though cause finding a fuse holder and a 200 amp fuse to go in it and then a dist block that a 120 amp and a 80 amp and a 50 amp can go into is hard. i want to go with all fusion wiring but their fuses only go up to 60 amp but their breakers go up to 200 . just gimmie some info plz thanks i won't be at the comp for about an hour, but i will be back as soon as i can
