So much much power should I actually give a hdc318?

[xmakeafistx 10+ year member]

Honestly I wouldn't go 3k daily on the sub, maybe 2200k on it but not 3k. Just to be safe, I've personally never had any problems with the soft parts.

The enclosure has a lot to do with how much they will take.

K gonna go 5.5 tuned to 36 on 2200w. And are you saying no break in is neccesary?

Everyone's setup is different. I will never recommend giving your sub more than rated. However we know some subs can handle more safely and how much power an amp actually puts out clean is changes too. Therefore if you are looking to be safe do rated, if you want overhead this is not a safe option but an option none the less and some people prefer it, it can allow for cleaner running of your amp and signal. What that sub can take safely I can't say you can take opinions from what other people with the same sub have done, but like I said everyone's setup is different and anything over rated I wouldn't consider to be safe if you feed more than rated you should be very careful run no bassboost.

alright, i have an HDC3 15" with aluminum coils, d1. at 2 ohm load. the actual load is 2.4 (1.2 per coil)

i have it strapped to two audioque 1200ds.

i have a couple batts etc. yesterday i did a comp, burped it at 49 and 51 hz. hit a 146.5

the box is 4 cubes with a flarred port more designed for daily but will get loud.

after the burps, went from 3/4 volume to max on each tone, the sub wasnt even warm to the touch.

IMO. these subs are great. this is my first audioque and am veryyy impressed with its capabillities.

i beat out another competitor using two RE SE 15s 139.6 (only had 1k power maybe), 4 Mmats 12s off a mmats 1600 (142.2), and another car using two dd 2515s (144.4) over all small turnout.

i was in streat beat 0-600.

all in all, daily, dont go driving around full tilt like an idiot. watch yourself. secondly, if your going to drop to a 1ohm load, make sure your power will stay up.

Stating what you beat in a competition does not really mean much. Being able to do good numbers is about the setup and application more then product.

AQ have decent subs but you do get what you pay for. Like any other manufacturer you will have issues to over come or expect, and giving a sub over it's rated RMS will simply put you into another..expect the worse situation. Just because others have gave a sub more power in their setup does not mean it will work out in yours nor does it mean it won't. It simply means, that it worked in their setup.

Pretty much cliffs for what I said. I agree, to be honest once you start sending more then full rms rating to a sub you start running into a situation where to me it isn't if you are going to blow the sub....its when. Having said that people have gotten away with sending massive power to subs that aren't rated for nearly that much, just keep in mind those ratings are there for a reason, sending them more can void warrenties and such. If you are not competeing just use RMS power if you are competeing use more and be careful.

Rated RMS by the manufacturer is the same as the RMS they give to amps. they get to pick and chose what they throw at it. look at SA 12s, 600rms and are doing 1k daily without any problems with designs. Why do all their amps do more than rated at the 14.4 or 12.9 Voltage? its a marketing technique.

of course you shouldnt be running 3k. adding in the aluminum coils will give it that extra shove to RMS daily runnings.

The reason i stated my Numbers and what others were running was to show what i was against, and their setups as a unit of comparison i might add.

146.5 in outlaw isnt great. whats it do legal low 140s?

i have an aq hdc3 18 dual 1 that was reconed by team psi and ive been running it on an audiopipe 3000d at 2 ohms for almost 4 months and it hasnt given me one problem

 

[Lowflyin 10+ year member]

I figure if it lasts till spring on 2200 I'll be happy.

What about break in? Na or ya?

When I recommend max power for music it's because I've used it and not even that after designing and building a few woofers you understand the variables.

Believe it or not but the aq ratings are very accurate for standard ratings..

1k continuous for 8 hours free air..

The woofers take much more because of impedance rise enclosures acoustical dampening etc and the pure dynamics of music..

When I say max that's clean no clipping and simply to help characterize the dynamics of the music..

Just about ever well built woofer will take 2x it's rms(8 hours continuous rating) for music as long as It's not clipped or extremely constant like techmaster etc...

Alot of people take non dynamic music and set the gains.. When the dynamic recording are played it's clipped far beyond what they originally though..

Note you should set your gains with a -3db test tone using 30-70hz tones..

If you properly set your gains you will never blow the aq with 2k..

Btw the hdc and hda are 2different woofers..

I highly suggest the hda 18 as it like about 7.5 tuned to 36..

The hdc has a very heavy copper coil which I don't care for..

The hdc has a 4layer roundwire copper coil 2" long..

They are good for 2500 or music..

If you got a 8 layer flat wound alum coil 2.2 it's good for 3kw daily..

Should I do break in or just play it?

 

[05trailblazer 10+ year member]

play it^^^
