ask as many qs as u like
cdplayer me normally cd player, pre-amp aur power amp sab hote hain.
pre-amp me tone shone set hoti hai.
power amp wattage bherhata hai
abhi jo aap ka setup ho ga uss me cd player aur 4 speakers hon ge
cd plyer se amplified signal jata hai speakers me
cd-player ke peeche aik out put hoti hai called pre-out
iss out put per pre-ampplifed signal aata hai rather than amplifed
yahan se out le ker aap apne external power amp me lagaian ge
aur uss se wattage amplify ker ke speakers ko connect karien ge
ab se aap ki marzi hai aap kia kia external amp se amplify kerna pasand kerien aur kia kia indash cdplayer ke built in power amp se karain
normally external amps are better then built ins so zida se zida channel external ke thru amplify kerna pasand kia jata hai
external power amps me depend kerta hai kitne channels hain.
aager sirf woofer hi amplify kerna hai to u can buy 1 channnel amp also called mono block
per u buying infinty speakers to wo bahut ache speakers hain aur external power amp ke saath zida achi sound production ho geee
so u need now 3 external power channels
iss ke liye u can buy a 4 channel amp. per normally 4 channel amps bahut high rating nai hote to shayad aap ko woofer ke liye kaam lage per even a solid 50watt RMS amp should do da trick
specially if uss ke channels bridge ho sakte hoon yani 2 channels ager combine ho sakte hoon to rating 100RMS bahut hoti hai woofer ke liye
nai to aap woofer ko bi amp bhi ker sakte ho yani amp ke 2 outputs aik hi woofer per laga do iss taran voltage nai increase hoti per current ho jati hai aur current hi humian chaiye hoti hai per do this only aager amplifer allows to do.
its always good to have a dedicated amp behind a woofer cuz at low frequencies the load is gonna drop to 2-3 ohms which requires more power input to produce the same level of output and at high volumes ur in-dash amp is definatly gonna clip.
