Car Audio Amp එකට බැටරියක් තෝරා දෙනවද

[mahagedaralaga]

මගෙ කාර් එකට Amp දෙකක් සෙට් කරන්න යන්නේ. Soundstream xxx 6500D , Boston GT 28 තමා තියන amps. Boston Amp eka 400W RMS. ( 2x200W @4 ohms). Soundstream eka subwoofer ekata. Eka 1600 RMS. ( Max power 7000W) . කොහෙද මේවට හරියන බැටරි එකක් ගන්න තියෙන්නෙ. දන්න එකෙක් පොඩි විස්තරයක් කියපන්කො.

The Boston GT 28 is an old workhorse, solid Italian made Amp. Also the Soundstream Monoblocks are quite popular.
You have to get it installed by a Professional place who does high end car-audio. Depends on the current car battery & alternator capacity. When you go with additional Soundstream amp maybe extra battery required.
Also needs more power bus plates on the battery side as well as on the amplifier sides. Also even though the amps come with an internal fuses, you also need additional in-line fuses on the power bus. So you need pro advice.

Thank you for your reply. Current car battery is 55A standerd battery with OEM alternator.

Thank you for your reply. Current car battery is 55A standerd battery with OEM alternator.

You mean 55AH battery... That's the rating the battery can deliver the load. Say if you draw 10A from it continuously, then it will last for 5.5 hours. (without being charged by the alternator)
(10A x 5.5H = 55AH)
It's not an indication of the current it can deliver. If you short circuit the battery then the max current will be dictated by the internal resistance of the battery. Maybe you can do a search on the net.

With your Soundstream 6500D, it can deliver 7000W. I am not saying that you can run it at that wattage. Say if you get 2000W out of it, when powered by a car battery , the load current will be nearly 170A. At full amp load the current will be in excess of 450A!
So clearly a small 55AH battery or your alternator cannot handle it.
Also if you don't power them up with large terminals and wire gauges there will be a voltage drop on the amp input and the amp will not function properly. So you need a professional installer.

මචන් ඔකට දැනට කාර් එකේ තියෙන බැටරි එක වෙනස් කරන්න ඔනි වෙන එකක් නැ. ඔය කියලා තියෙන වොට් ගනන් හැමවෙලාවෙම ගන්නේ නැනේ. අර ඔකට 170A අදිනවා නම් ඔක උබට කාර් එකට හයි කරන්න වෙන්නෙ නැ. ඔකට car audio කැපැසිටර් එකක් දන්න ඔනි මචන්. නැත්නම් deep base වලදි ඇම්ප් එක mute වෙනවා.

There are buffs who go higher... The SoundStream 15000D delivers 15,000W of power and draws in excess of 1400A at highest power levels.

මිත්‍රයා ඔයා කියන්නේ 15000W audio system එකකට 1400A ගන්නවා කියලද?

These are special class D amps designed to work between 11V- 16V power supplies. The amp is able to theoretically and practically deliver that power. At extreme power levels it will draw that much of current.
At zero signal, just powered up it will draw 8A for electronics.

Thanks for all the replies. හුඟක් දේවල් ඉගෙන ගත්තා. All the specs I got it from the owner operating manuals of the amps. Boston Amp protected by two 40A fuses. I can't see the soundstream fuses.
By Installing a bigger Amh battery will burn out the current OEM alternator?

Boston has fuses but usually audio installers add external fuses as well. The Soundstream has protection plus some models have internal fuses.
If you draw out too much current the alternator will max out and will fail soon. Also the battery will overheat.
Talk to a Pro guy who does these things. High wattage audio needs different electricals to consider. I am aware that many add extra batteries and change the alternators and do the proper gauge wiring to power up the amplifiers. There are aluminium or copper bus bars which attach to the sound stream to power from several sources.

thanks for your nice explanation. very much appreciated. definitely i need to update my 55Ah standard battery to a higher Ah battery. if i replaced the battery by higher Ah battery (example 100Ah) is there any chances to burn out my OEM alternator? Thank you.


Thanks again sharing you great in depth knowledge regarding this matter. I think am talking to the pro guy by the explanation and the way you shared your knowledge texted. I clearly understand what you are saying here. I need more knowledge before installing the system. Are you living in SRILANKA or .... thanks
