Install Amp in car.

Installing amp in the car must change battery or not?

Is offen question like to be a classic problem. If the state will need to explain a little bit longer. We try to understand about that the better of this issue. (Car audio is easier ...). First, understand the basis of electricity is

1. Current (value is amp : A) power is like the volume of flowing water through water pipes. If more water flows through. It means using high-power.
2. Voltage (value is volt : V) This is already known the electrical system in car used 12 V this valve like pressure of water pipes if water have more pressure, water is flowing better try to think if pressure from 14.4 V sound from audio amp must over than the voltage 12 V.
3. Power (value is Watt : P) this values can calculate from P = IV you know more power of Amp. must used more curent. For watt often have debate is maximum watt (max watt) or average watt (RMS watt) then measure at how much resistance but please do not be confused. I have a simple principle for comparing the watt of amp is not compare with max watt because max watt can not infrom about quality of Amp. as exactly. Must be used RMS watt is to guide power of sound every frequency band to calculate power from Amp. and the reference value should be 4 ohm speakers and calculate at 12 volt to be the same criteria (converse RMS watt to max watt is multiplied by 5)

This time is to be understand about battery. Batteries installed in cars will show 12 V. But when we measure is approximately 13.8V. And when using the long time. Volt value is reduce sometime remaining 11.5 V. and have problem is can not start the car or power on audio when have more bass sound light of screen is flashing.

Other information of battery is ability to make current (amp hour : AH) bigger battery have more AH than smaller battery. This value mean efficiency to make current (more watt of Amp. must used more current) Now the problem is that when the batteries we use for long time (generally 1-2 years Battice will get worse). Ability to contain current or Amp. will reduce by voltage will reduce untill we can not start the car because distart want current and power to much. When battery can not make current must be cahange new battery. We know about battery only that.

end for today will be continue tomorrow.

Thank you.

speaker size of car audio

Speaker size of your car?

Problems that often when install a car audio is when go to the audio shop. Try to listening speakers and like this version of speakers and then want to install this size. But it appears that version of the speakers made out, but 6 inches but the size of your car by just inches 5 car or just some down to 4 inches.

Q 6 inch pack that can install? Receive a response from the audio shop that has no problem handling a single technician.


Problem that is often enough technician speakers are larger than the ability for loudspeaker box. To the rear speaker clash with windshield. Added to wood panel. General technician only add wood panel or better is spray color but not use tape to prevent from the water. And usually is need to cut the steel panel. to install speaker. Sometime is install speaker successful but problem is can not closed the door. Most shop owners said install larger speakers is better than small speakers. Refers to sound from 6 inches is better than 5 inches. But you know that really voice of larage speakers usually good in the cabinet and bass voice only. You know that speakers installed in the car is install with no cabinet. Happens is radio system or the power does not have system to cut bi-amp or cut out low frequency sounds. For example, you use the radio speakers installed beside the door. When you speed up bass sound and loundness with a bang. Your speakers shake violently. You think that guitar voice or singing voice will still. It is band and audio out is very bad. So not true that install 6-inchs speaker it will sound better than 5 inches.

Speaker size of your car is
