how to maintain car voltage at 12vdc?

[matthewtan]

I wanted to install an amp which stated that the voltage supply cannot exceed more than 13.5vdc.......... In car the voltage can peak to 14.4vdc.

Anyone out there can give me any suggestion how to maintain my car voltage between 12vdc to 13.5vdc?

voltage stabilizer???....

jz my 2 cents...

install a digital fuse... so u dun hav to worry ur amp roask....
or u wan then u install a capacitor (big bomb)

normally amp is rated at 14v
nothing 1 lah...just do some proper grounding and and a good voltage stabilizer should help

 

[howiechoo]

erm , i never saw an amp is able to go to 13.5 only...i think u misread the voltage is it? is it the normal working voltage or the recommend voltage or the amp can generate maximum output at 13.5V like 150rmsx2 @ 13.5 ??

fyi, VS, digital fuse and anything wont make ur voltage change..

normally amps n electrical stuff in a car can accept a range of voltage from 11V - 15V/16V like dat... n most amps work efficiently at 13.8V...

i dun think 13.5V is the limit of the amp.. i think no manufacturer would be so dumb to make such amp with 13.5V limit...


a voltage stabilizer is to stabilize voltage... not REGULATE voltage.. so it wun help... n fuse works on current... not voltage... n this is not de case for fuse tho...

ermmm... voltage stabilizer does regulate voltage. In a voltage supply with peaks and valleys, voltage stabilizers comprises of many many capacitors which would release its storage during valleys and hence smoothen out these valleys. Would it not be regulating voltage? I guess u mean that it does not regulate voltage in terms of a max cap limit. ;)

 

[khguan]

no it doesnt.... regulating means limiting the voltage range from the lowest allowed voltage to highest allowed voltage... for eg. 11V - 16V

for voltage stabilizer...it smoothen the voltage fluctuation by absorbing spikes n fills the "valleys" or sudden voltage drops... if the overall voltage drops... it follows... if increase... it follows too...

 

[kruger]

never heard of amp that limit to 13.5v only.... Must be very special kot... ;)

 

[matthewtan]

thanks for all your suggestions

Anyone knows where to get an 12vdc to 12vdc ( adjustable variable output from 11vdc to 14vdc) regulated power supply in K.L.

or voltage stabilizer i.e. constant at 12vdc or 13.8vdc

 

[drexchan]

i am amazed by the following statements:
1. an amplifier that has a 13.5V voltage limit.
2. saying that a VS can regulate voltage.
3. using a fuse or a capasitor to deal with the voltage.

 

[ksgoh]

that's right dr. chan.....but at least u explain in ur professional way, so that we can understand better in those thingy....

 

[drexchan]

me not pro in electronics, amps and so on.. but common sense. i think khguan have explained it all.

 

[matthewtan]

Ok guys, I brief u on what amp I am dealing with!

Is the amp kit review by the star audiophile section not long ago....a 12vdc amp kit using tripath 2024. The max. voltage is 14vdc, anything more ...u know lah.

I looking for something to keep the voltage constant or fixed around 13.8vdc max.

hope u all can understand what I need now.

 

[bongweeyap]

just install the amp lahhhh.
don't care the voltage thing and spend the maney for VS or something else.
just remember to add one fuse(big one).
the amp won't rosak wan lahhhh.
if u go to the shop u will end up buying this and that which are not required for just putting in ur amp.
i,m working in car acc shop in kajang.
handam only on worry.
even the branded amp like kenwwod,MTX, Soundstream oso handam only.
no need thosee VS or wat.UNLESS U NEED A REAL GOOD SOUND QUALITY.
just remember to add the fuse.it will cost u round 20 bucks only.
