So you can not connect your seps to it. If you do your amp will see a 2 ohm mono load and blow. For your seps connect your left to channel 1 and your right speaker to channel 2. Don't forget the crossover.

You can bridge channel 3 and 4 and connect it to a single 4 ohm sub.

Power rating wise, your amp and speakers are ok.

ahh ganun po ba... yun seps ko kasi 4ohm yun eh 4ohm din yun sub ko,, bale ilan pong watts ang mabibigay ng amp ko sa sep ko?? maamplified na po ba yun seperate 2way ko at tweeters?? thanks po sa mga suggestions..

Seps midrange and tweeter connected to passive crossover will get 55 watts.
Sub will get 200 watts (bridged channel 3 and 4)

hindi po ba bitin sa sub yun? o ok lang? dba po dapat match ang rms ng sub at amp?? ganun po pala yun pag 200wx2 ibig sabihin yun dalawang channel pag bridge 200w ang makukuha??

sensya na po dami ko tanong hehe
1.anu po ba pinagkaiba ng sub na 2ohm sa 4ohm?

Ok lang 200 watts to your sony sub. Easy to drive ang sony subs. Try it 1st kung bitin ka then you can always add a bigger amp.

1. Ohm is a measure of resistance. Lower number means less resistance. Most amps can only play into 2 ohms. A few high end competition amps can do up to 1/2 ohm loads but they are very expensive. Generally giving your amp a load that is lower than what it can accept is a good way to kill an amp.
2. You said your seps are rated 60 watts. 120 watts will be too much for it. Might blow your tweeters. You can normally give a speaker more power than its rating but double is pushing it.

ahhh thank you po,,bale yun channel 1 and 2 maproproduce niya 55watts? tapos yun channel 3 and 4 bridge 200wats,, nakita ko yun test result ng actual nakalagay sa 45x4 into 4ohm is 58w nung actual tapos yun 60x4 into 2ohm naging 88w!

Accrording to the test report you mentioned , channel 1 and 2 produces 58 watts each. So its actually 58x2 for your fronts. Perfect match for your 60 watt seps.

Difference betwen dvc and svc is versalitity. You can use a dvc as svc or dvc and you have more wiring options. But if you are comparing the same model they should sound the same.

boss bale yun 55x4 na dynamic power na lang yun papakabit ko noh?? tanong ulet kung sa sub ko lang kakabit yun amp ko pede po ba dalawang bridge sa sub ko? yun dalawang 200x2 bridge or ganto 120x2 bridge tapos 200x2 bridge?? pede ba to sa svc na sub ko??

Pakabit mo lang seps. You will get the 55 watts. Wag mong sabihin sa installer na ikabit sa "dynamic power" tatawanan ka noon.

In your case, marketing ploy ng mtx yung rms and dynamic power. Your amp has an unregulated power supply. This means that your amp will produce its rated power at 12 volts but give out more juice when fed 14.4 volts. If you noticed they rated rms at 12.5 volts this is the normal voltage of a car battery. They then claimed dynamic power at 14.4 volts. Your car will usually delvier 14.4 volts when it running. So more often than not, you will get 55 watts per speaker.

It seems that you have your heart set on getting 400 watts to your sub. Just tell the installer to bridge channel 1 and 2 and connect it to one voice coil and bridge channel 3 and 4 and connect to the other voice coil. Your sub will see 400 watts. Note if you do this you need another amp for your seps.
