ano ba magandang amplifier para sa mga pampasaherong jeep na pweding ireplace sa mga transformer type na booster. ung mga booster kase nila aabot daw ng 200 to 250 watts.

meron kaseng mga amplifier na alpine yata ung brand na malaks din. pano kaya lumakas un eh 12 volts lang ung battery.

suggestion mga master.

sir my DC-DC boost converter un sa loob, 12V to around +/-35VDC. kya ang lalaki ng rating ng fuse nun 30A to 40A swaping current for voltage

hey! bi or tri amp system na lang muna. wag muna yung may pwm na boost converter. mga 50-50 watts muna. overkill naman ata agad yun. malakas na din yung bi-amped na 50 watts. 4 amps in all. nag backout tuloy si sir roland sa project.

insomartin · « **Reply #6 on:** July 11, 2009, 04:26:41 AM »

or triamp... dual 50 watts for subs. then isang 50 amps for midrange/tweets.
TDA1562 or LM3875 amp...

yep! it's gonna take 40v to get 50watts.. but... i'll stand corrected.

good idea

pwede ung mga gainclone na BTL or bridge topology kung 12VDC lng ang supply cguro mga 15W per ch @ 8ohm load, pwedeng I boost ang ouput using descrete power transistor parang hybrid, IC Amp+descrete class B output stage para mkapag drive ka ng low impedance as low as 1 ohm.

Roland · « **Reply #9 on:** July 21, 2009, 08:12:50 PM »

pano ung discrete class b output bossing. penge ng schem hehehehe. baka kaya kong gawin.
12 volts din ba ang supply ng output ?

sir madali lang yan problema mo,subok ko na,bale mag assemble ka ng amplifier pwde naun kay marconi pagarigan na 100/channel tapos kahit 6amp lang gamitin u transfo,sa 110volts mo gamitin tapos bili ka ng inverter.un 12v to 110 volts kahit mga 600watts lang.madami yan inverter,same principle lang naman kaya lang u have to do it on your own,tapos i bridge mo yun amplifier,pwede ko ituro sa iyo ang pagbibridgre,simple lang yan

ang lakas na nung 200-250 watts!! lalakas talaga dahil depende yan sa amperes ng supply...
