Full Version: FUSE in SPL setup ?
do you use fuse on + cable when You go to competition ? or You stick some huge wire instead of fuse ? Or maybe + cable direct to accu and to amp(s) ?
You must always fuse a road car.
You can bypass the fuse with a solid link for SPL comps only, ensure a fire extingusher is close at hand!

To answer your question heres it direct from the rules book
Custom auto sound installations may affect the safety and/or integrity of your vehicle. Although some competitors may elect to have their sound system installed by others, it is ultimately the competitor’s responsibility to validate that his or her installation is safe. Particular care should be taken with regards to electrical wiring. All power wires should be fused directly at the battery to minimize the risk of a fire hazard.
but yeah not fusing any amps is pretty much not a good idea. if run for short periods its not to bad but yeah its at owners risk to do so. but for comps ya have to have a fused cable that passes scrutineering

Ofcourse for everyday use i have fuse but when u go to comp??
" scrutineering" whats that :S, sry bad engl

Wrong, you don't have to have fuses to compete in SPL.
Fuse in SPL??? All a fuse does is act like a massive resistor and restrict current flow. If you are not sure of your wiring abilities and or what you are doing then fuse your system. Don't expect great performance from a system with massive great amounts of wiring when you have to pass all that current through a 3mm bit of metal, it just doesn't work that way!

I got 8 runs of 0 gauge the Mirage unfused for competitions.

i thought that they changed the rules and you had to have a fuse in street classes?
i remember being at a dorans event and tony telling us that for the next event we had to have a fuse?

a fuse is not like massive resistor.
it has voltage drop but then again even 0 guage has volatge drop. would only be mico ohms. i will test one at work next week if u like.
a resistor is does not limit current in series DC circuit current remains the same.
but fuses are pretty much needed and match don't forget to match a fuse to ya cables AS WELL as ya load.
i can assure u that running a fuse will do jack all for teh volatge at the amp.

There is a reason that most purpose built SPL cars and even some street cars don't use fuses.
They may only cost you .1 or .2 db (not in all cars of course) but that can be the difference between winning or losing or even setting records.

or yea i know that some cars have valid reason for no fuse. but i presume in this case he isn't a pro going for records or getting show stopping numbers.
.01 or .02db is more likely as well.

so 158.0db and holding the aus record for ex 3-4 isnt going for records and show stopping numbers???????????
its currents w.a.'s loudest car that is actively competing and about the 4th or 5th loudest in aus.
but is that oxyll or not?
if he has taht car im sure u would know teh importance of fuse and were to and not to use one.
pigphama might have legit reason for not using a fuse in comps.
but 2 db difference come on u get 3db if u double ya power "in theory"
it makes sweet FA difference.

I have seen the differences fuses make in numerous record breaking cars.
Fuses do create large enough resistance to make a difference in competition.
That is why most serious competitors DO NOT use fuses while competing.
Out of competition is a different thing tho....!
I fuse everything in my car, but it spends more time on the street than in the lanes.
If I were to build a dedicated, SPL only car I wouldn't use fuses.

ok well think they need to change the rules on dbdrag website as the rule i quoted was cut and pasted straight from their site so i think that rule needs to be updated. changed as i only stated what the rule book had in it

Billy, this is the entire paragraph from which you took your "ruling".
If you read the entire thing (esp the bit in bold and underlined) it is clear that it is merely a recommendation rather than a rule.
Tony Doran enforces the use of fused for his comps only, which is fine, he isw doing it to look after his own interests as well as those of competitors.
oh ok my bad sorry bout that and yeah cause tony doran enforced that rule i thought it was the rule.
but good to know now can see how i go without fuses and if it makes a difference and whether or not to go without em for future comps that dont require them

remember tony's house rules no fuses no compete thats his rule and it will stand at his comps
yeah know that one from a car trying to enter before with no fuse last comp. but for other comps like the finals and autosalon. but rather be safe with mine anyway.
