Car Audio Batteries


If extended engine off listening is desired then a second battery can be useful. Keep in mind that this will put a greater strain on your charging system as well as add several hundred dollars for a second battery, dual battery isolator, and installation charges. If you are having problems with your charging system then you might need a new or larger alternator. Have it checked out by a qualified technician.
Features and terms that may be encountered with regard to wiring are:

Butt Terminals: This type of terminal resembles a long barrel and is used to connect small gauge wires together. These type are crimp terminals and considered less desirable than soldering when soldering is an option. These terminals are also sometimes referred to as crimp connectors though that term can apply to many variations of crimp terminal.

Deep Cycle: A battery usually reserved for marine use that can be drained and replenished many times. While popular years ago many installers have relegated this battery to system use only with a traditional car battery for main power.

Farad (F): The base unit of measure for capacitor storage. One farad is very larger and is equivalent to one million microfarads (uF).

Gauge: This refers to the diameter of the wire. The smaller the number, the larger the wire. Sixteen is common for speaker wire, eight is common for average size amplifiers, while four gauge and below is used for large amplifiers. For reference, four gauge wire is about the same diameter as the average male pinky finger.

Gel Cell: A type of battery that uses a gel type acid. These batteries can be desirable because they may be mounted upside down without the danger a standard type battery would pose.

Heat Shrink Tubing: A type of insulating plastic that resembles a drinking straw. A small portion of this tube is cut off and placed on a wire before soldering. After the connection is soldered and cooled, the tube is slid over the joint and shrunk around the wires by means of a heat gun or hot hair dryer.

Microfarads (uF): The more common unit used to measure capacitor storage. One million microfarads is equivalent to one Farad.

OFC: An abbreviation for oxygen free copper. This is the most desirable wire to buy and there is really no reason to buy any other kind. As the name implies it is pure copper that is free from oxygen impurities.

Spade Terminals: A type of terminal used on most speakers. The type found on speakers are male spades while the ones used to connect to these terminals are female spades. These terminals are also referred to as quick disconnects though this name can apply to many different types of terminals that come apart quickly.

Voltage Rating: Referring to the amount of voltage a capacitor is rated to handle. The very least a capacitor used for reinforcement should be rated at is 16 volts while 20 volts is much more desirable and available on the slightly more expensive capacitors.

hehehe...sa mau buka da juga ba tu....malas da banyak2..mau tukar selera lu....

alala..mau tkr slera main pa skrg nie bro cla'e?hihi..

men sikit2 jak ba suda ne...sub pun ada di ruma da....

yg pnting karan lh..hihi.

nada karan nada sound2..hehehe

btl 2 bro..

kalu msh nda ckp karan, sambung dr karan rmh.....

2 malatup sound.hehe

nda jg ba... pkai ja volt changer..... hehehe...

utk apalah 2 bro...?

klu gna karan umah cnfrm karan 2 x drop uda..hihi.

ya ba.... berapa puluh amp pun kompom stabil ja.... hehehe

mau tau woofer 2 ja thn ka atau x kna blast lma2..hihi.

ya... tp bil kompom naik mahal..... silap2 kana potong tu karan rmh...

bngung trus SESB npa kuat btl 2 umah mkn karan..hihi.

nda jg ba dorg bgng... yg pntg ko byr bil

klu x tbyar cnfrm x karan lh umah 2 kna ptong..

tu la psl.... jd men la car audio....
