mga boss, planning na maglagay ng mono amp sa simple set up ko, medyo newbie lang po eh hehe.
yung subs ko po sir is firland audio FA1280, nakalagay po is 600w RMS dual 4 ohms. (di ko to gets)
plan ko po ilagay na mono amp is yung kinetic KD800.1, eto po yung specs :
Supply Voltage 11~15V DC
Power Output 4 Ohm 350W X 1
Power Output 2 Ohm 560W X 1
Power Output 1 Ohm 800W X 1
tapos eto naman po yung sa sound magus DK600:
600W x 1RMS(2ohms)
400W x 1RMS(4ohms)
question po is anu po ang ipapalagay ko, yung kinetic KD 800.1 or yung sound magus DK600 po? alin po mas malakas sa kanilang dalawa para sa subs ko? kasi yun po di ko gets yung 600w RMS dual 4 ohms na nakalagay sa subs ko eh.
help po mga gurus, salamat po, sorry talaga sa question.
thanks po. :D

kung sa lakas, yung kinetic. pero sa quality, di ko pa na-try pareho yung brand na yan e.

subs with dual voice coil for flexibility. for your subs with 4 ohms with dual voice coil. if voice coils are wired in series the impedance will be 8 ohms. if wired in parallel , the impedance will be 2ohms. so in theory, the DK600 is perfectly matched with your sub.

Ganito lang kasi yan.. the typical subwoofer driver has a SVC or a single voice coil configuration. Nakikita mo na ito agad because it has just two binding posts. Nowadays, we have DVC drivers or dual voice coil configuration which has 4 binding posts. The advantage is simply flexibility to dictate the nominal impedance presented to the amplifier.
For your 4-ohm DVC subwoofer, you can either wire it in parallel so that your subwoofer will present a 2-ohm load to the amplifier or you can wire it in series for 8-ohms. Electrical common sense and ohms law dictates that the lower resistance you have, the more power you get. This is why nobody wires these things in a series configuration.
If you want to get the best out of your subwoofer, you typically buy the 2-ohm DVC version. This way, you can wire it to present a load of 4-ohms (typical car audio resistance) or 1-ohm. Again, the lower the ohms.. the more power you get hence louder bass.
If you base their specifications on paper and assuming they reported the same specs at 14.4V, the Sound Magus DK600 would be better. However, the Kinetec is stable at 1-ohm and that is a very big factor in mono amplifiers.
What people should know is that fooling people around is pretty easy on paper especially when it comes to budget amplifiers. Take Lightning Lab for example.. hook their mono amplifier off the deck and feed it the typical 13.8V and you'd often see a -10% performance from should-be-specs at 13.8V. So what are the true rated output of the two amplifiers? Dunno.. take a leap of faith or urge them to take CEA testing.
Personally, I wouldn't go out and buy both of them.
My point against Kinetic (as I am open to state seeing this is a public forum) - I dislike the distributor of Kinetic. Not because of their products but rather on how he avoids technical matters on his products. (1) Claiming the manufacturer is the same OEM manufacturer of DLS in Taiwan [DLS is manufactured in Korea ever since their partnership with Genesis expired], (2) "Sir, is the mono-block Class D?" -> "Mono block po sir" [Anak ng.. tinatanong nga what topology is inside. The customer already knows it's a mono amplifier] (3) Regardless to say, saying it is a "space-saver" is negative in amps. Sure it's Class D, but power and size are polar opposites.
Issue number one caused an uproar sa KAC last year. I still remember that incident and it pretty much left a bad taste on my mouth.
My point against Sound Magus - it isn't 1-ohm stable.

I have not heard the Kinetic so no comment on it.
I have not heard that particular model of sound magus but I own a different model. It works. Its a good inexpensive sub amp. Its rated at 600 watts * 2 ohms so its a perfect match for your sub.
Choice I would have made as well.:nod:
2024 Innova Zenix 2.0 V CVT (non-HEV) vs Innova...
