You sure using a class A amp to power a subwoofer is better than a class D???? You should do a research on the classification of amps. By the way, nobody will want to use a Class A amp to power subwoofers (even if their vehicle electrical system can support that). Another interesting point to highlight is that a true Class A for a vehicle is so expensive and limited in production. Audiophiles will use the Class A amp to power their comp. speakers.

Current Soundstream producing Class A amps? I highly doubt it. Even their legendary Human Reign series are not Class A. As for an audiophile, most will prefer 2 channel amps (mostly they are Class AB) to power their subs owing to better control/damping properties (but on the expense of efficiency). As for those looking for a louder system, a Class D amp (assuming similar power rating) will be much more efficient. Hence, the popularity of recommending a Class D for subwoofers.

Another thing to bear in mind that not all Class D amps are inferior in SQ (perhaps due to higher THD and lower damping properties). Lastly, can you really hear the difference in sub bass???? Boominess yes, but not neccesarily the overall ambience in what you are looking for from the subwoofer.

dont get so excited la, he's a relative newbie, as u can see he only experienced one amp. i think he means class AB and not class A, and his view was also qualified by saying from his own limited experience.

hahahaa.... one thing about soundstream their amps are nice... i mean in terms of outlook.... the new lil wonder damn nice one..... shit!~ tgk pon cair.... hahah!~

Alpine PDX amplifiers have nice design too.

Looks bellies the sound huh.

Hello guys, Class D amps are not inferior. They are just made differently to be more efficient for a particular band of frequencies. In fact, they cost more to manufacture than a typical class AB amplifier. For that purpose (in running a subwoofer), they give higher output and can be as efficient as 80-90% of usable power and runs cooler too. Furthermore, Class D amps allow you to run at lower impedance to double or even triple the power (2ohms or 1 ohm) which a typical non-high-current class AB amp can never do.

If you ask me: A branded 2ch class AB amp (non-high current) vs a branded class D monoblock. Which would i choose for my subwoofer duties? I would probably pick the class D monoblock. However, if I can find a good class AB monoblock, would probably go for that!

Some amps like TRU Hammer, Focal Solid 1, Zapco iforce i600 and Reference 500.1 are Class AB monoblocks. Yummy!

yeah.. pdx also nice.... but helix also nice!~~~~ heheheheehhehehhe:P

no worry u can dump your ugly amp to me, i need something bling bling and solid as coffee table

hey guys...just want to ask..right now i have subwoofer+amp..but i want to remove the subwoofer...so left the amp, but if the normal speakers connected to the amp, will it spoil the speakers??...do i need to remove the amp if i remove the subwoofer??

if its a mono amp then maybe not suitable for speakers. if its a 2channel amp then is ok...

no any old school nice stuff to introduce??~~~

click my signature la, got some...

can i noe wat is SPL? T.T

SPL = Sound Pressure Level

SPL cars are the ones going boom boom boom around town

SPLP competitions are for measuring how loud the car can play. they dont use music, just some fart sounds.

too bad in this country when u say u are into car audio, they automatically think spl...bcoz so many show cars are spl based...

Glad to see my amp & speaker include inside SQ
