This is my first project, i need some professional opinions about my parts because ive just started into this, these are all the parts ive ordered and i need some help with power supplying i will explain it in the second part.
Amplifier:
XH-A305 Bluetooth 5.0 Stereo TPA3116D2 50Wx2+100W 2.1
Input voltage: DC12-24V
Working Current: more than 3A
Crossovers 2x:
GHXAMP 60W 2 Way 2-4 Inch
Crossover frequency : 2800Hz-3200Hz
Frequency range: 50Hz-22000Hz
2x Fullrange:
Sony 1,65 inch 12.5w 4 ohm
These are good, but i dont know the sensivity and freq range.
they were from a good sony loudspeaker.
Tweeters 2x:
AIYIMA 4 ohm 80W 1.5 Inch 25Core Fiber Membrane, Rubidium Magnetic
Frequency range: 1.5k-20kHz
Sensitivity: 93dB
Subwooofer 1x:
GHXAMP 4ohm 40W 3 INCH
Frequency Range:60Hz-20KHz
Sensitivity: 90db
Passive Radiators:
1x 3inch for subwoofer
2x 1.8 inch for sony's
Power:
My parts:
1- Self locking 24v blue button
2- Latching blue switch AC 250V/15A 125V/20A
3- 6S Feiyang balance function protection board
4- Voltmeter panel DC 2.5-30V Blue
5- 6S Lithium battery capacity indicator
1st question: so lets say im supplying 23 volts to my amp, if no woofer is connected, am i damaging and killing it? if half of the woofers are connected am i damaging my woofers because of the more amount of power then needed? lastly if i dont connect anything to my subwoofer what happens to those bass signals? would they get back to full range speakers? or they would just disappear?
2nd questions: This would work?
As you can see im thinking about supplying it with 6 lithium batteries in series and charge them with a laptop charger, the laptop charger i have is:
AC INPUT: 100-240 v - 3.5A 50-60 Hz
DC OUTPUT: 19 V --- 11.8 A 230 W
3rd question:
Lastly about the batteries, i have 3x lg 2400mah and 2x 2100mah batteries, as far as i can understand, i need same mah same brand batteries? so i cant get 3 more 2400 mah random brand batteries and stick them in with those lg's?
