Hi guys , I'm currently having a problem with my 4 Channel magnat BullPower Amp, using 4 Channel .

Encounter problem

Tweeter not responding , Front door speakers not working , only Rear ,

If switch to two channel my Tweeters are working .

pls list out how many speaker that you sumbat in your amp
and the location as well...
if can draw a wiring diagram ..
easy for us to trouble shoot them together..

From The Diagram

It Shows that The player connects to the Electronic passive Crossover then to the 4 channel AMP

High Pass ( Tweeter )
Band Pass (Front Speakers )

It Occured recently my front tweeters , there's no sound , but tested already that all the speakers are working well.
After today the two front speakers no sound from it, where else at the amplifier i turned the switch from 4 CH to 2 CH my tweeter works but my front still not working.. what could be the problem could it be my Electronic Passive Crossover?

by pass the electronic xover, just test 2ch input from player to amp, test front 2 ch and then rear 2ch, use midrange speaker on output side for both test. if all ok then it could be the xover problem.

my guess is your amp switcher or x-over switch(cause you didn't mention which switch you you turn)...the 2 chl to 4chl..switch thing

the reason why your rear speaker is working cause it is wired direct to your source unit...

only your tweeter and your mid..is connected to your amp..
Maybe amp switch or ur electronic x-over switch is the culprit.
you need to either try change ur electronic x-over or ur amp.

hope this help.
