you prefer precise tight bass that isnt muddied

guess what, so am i and majority of people here! (though i think some of them just took it a little too far for my taste haha )

If not mistaken got 2 which better than JL Audio before but 1 close shop edi:-

1) Image Dynamic
2) Adire Audio

The mmmmmmm sound, sounds more like the car metal is vibrating to me.

lots of subs out there = one note sub. u can literally hear the sub only plays a single note...either the sub at fault or the enclosure. A very common syndrome but most are not aware of.
So if u find urself needing to cross the lp at 50hz, most probably ur in dat category. Juz to share.

Sorry bro. I'm at lost here. Care to explain further??

Bro MyWifeCar,
I think i can differentiate between sub sound and car metal vibating sound. Hehehe.. Just to add last week. Saw 1 myvi installing 15' lightning audio sub. Rear compartment full. Have to take out the rear dash also. But if course this sub also have the mmm sound. Thats the other story. The owner goes for spl, surely. Anyway, what amuse me is when he's going home, from far i can hear the rear wiper vibrating. Hahaha.... And its from 10-20 meters away....

Aahhh... So thats what its called. "precise tight bass that isnt muddied". Hehehe. Really made a fool out of myself with the mmmm sound eh? Thanks quazacolt...

the mmmm sound freq range are from mid bass / bass mid (80-200hz), not sub bass. sub bass are below 60hz....for malaysia style spl, they like to make ur 12" sub work like a 6" midbass so you get the "kick". and it is common used for car with improper install of midbass at front(so their 12" are used to compensate the mid bass)...then they got the mmmmmmm sound......

used JLW6 mau ka? hehe....

I see. Its just the setting la. Not the sub itself. Meaning all sub can be eliminate this sound, is it?

But seriously, got people like the mmmm sound meh?

SPL = sound pressure level

having the sub to play at higher frequencies does raise the SPL since its "constantly" working (where it shouldn't LOL!)

Hmm. True also... Have to agree on that. Lol. But is it allowable? I mean in competition.

SPL competition, is all about dB only.

Most likely a lot of ppl just simply hantam one sub box and call it a day... How well a sub performs depends a lot on the design of ur sub box... Plus a lot of other factors too... If u hear the sub farting... A lot of times it's lp freq, amp gain and box construction.

Guys,

Just a general question. If we have a 500w rms sub. Should we get a 500w rms amp or more. What do you guys think.

more, something around 700-800W would be nice, i usually look for 50% more rms...

How about 100% or more power?
If the sub is rated 300W RMS, 1200W max. Amp supply 700W RMS, 1000W max. Will this kill the sub? Was wondering

I think power is more about control, and won't lack when you need it.

For a 700rms amp, why don't you just get something around 500~600rms sub?

Of course, it won't kill the sub unless you force it.

I'm curious on what would happen if I done that lol. Force it? How?

Force it means pushing it too hard until above the rated power. Ever heard of a sub blowing?

Above max power handling? Youtube shows crazy ones. They use home power supply wafak

as long as amp not feeding distorted signals to the sub should be ok, but lifespan of sub will be shortened la, i do have frens running amps double the rms of subs, in sq will be ok, not much loud bass, volume also never blast..
