I have a subwoofer with this spec :



And my amp have this parameter that can be set. Any idea what is the best setting for my amp using above s/woofer.

Thanks.

just put to sub channel...then from there tune ur frequency at ur preference....50-300hz....

SQ or SPL?
Are you playing active or pasive?

Not really understand that term SQ and SPL, izzit sound quality and sound power level? Sorry noob here

By the way this amplifier connected directly from subwoofer output from my HU.

SQ = Sound Quality = Vocal and musical
SPL = Sound Presure Level = Boom Boom Boom

For SQ & SPL, amp sub frequency setting also diff...

best of both SQ and SPL... set the freq to 80Hz...

I'm more on SQ then, because I heard various type of song. Not only the boom boom boom song.

craziechild, thankz for the suggestion. loon1031, thankz for the info.

80Hz is not too bouncy... hehe.... i guess bounciness biggest effect is the box...

try starting with 50Hz... going up till what ever frequency point tht is the most optimum...

optimum as in the position is at front while its the loudest point where the sub bass loudness doesnt cover up the front mid bass... tht is your best setting... if its too loud then lower down the amp gain...

well tht how i do my tuning...

ciao...

Thankz bro... How about the gain level. Is it OK if I put it to maximum?

gain should be put to as minimun as possible... the higher the gain the higher the chance of getting distorted signal and you might burn your sub vc...

Try to set the gain to minimum, the try to set higher a bit if minimum not satisfy you.. untill ngam ur taste then stop or do marking or record...
Then try to higher a bit, if bass to strong then tune back to the marking or record level...

Not advice to maksimum the amp gain.

OK, will try it out. Thankz a lot for the suggestion and Happy New Year 2008

amp gain is normally advisble to put not more than 12 o'clock...mine at 7 o'clock only & my Hu volume at 20 minimum...thats my listening....
betwn what shud it be for a comps set frequency?Mine at 63hz & find my midbass bass is too high& now i switch it to 80hz....but somehow my tweeter not enough details....

betwn issit for passive comps set, the tweeter frequency is fixed, we only adjusting the midbass frequency only rite? Correct me if im wrong?

betwn im dun have subbie yet cos wana get my fronts setup right first...somehow i taught im might lack of low frequency which currently i depend upon my midbass. My thinking is if i get a subs, i put the frequnecy of the bass <80hz while my comps will be at 80hz...then will this solve my problem ?

For my setting, the amplifier only serve my subwoofer meanwhile other speaker was connected directly to HU. So all my amplifier settings was to improve the bass sound.

For your setup, you use amplifier to power up all your speaker. May be if you get passive crossover and amp with more channel will solve your problem. And for subwoofer setup, we can follow range give by the subwoofer specification.

Just my noob thought.

for passive setup, yes the hp for the tweeter and the lp for the mid is set... some passive crossover may give you an advantage of selecting the frequency but the most is jus two points... but most crossover will give a variable slope setting... and yes.. you use the high pass x-over from your hu to bandpass the frequency range.

but anyway... as for your issue here... i think we cannot determine tht your problem can only be rectified when you really installed your sub... crosspoints are not very important to start with... the thing tht is important is how it sound at certain crossover point... i have audited systems where the cross points is 100Hz 6db and still sound upfront and not boommy while also having listened to systems with 50Hz 12db with the sub coming exactly from the back...

and yes... check out some of my recent post... no mid can replace a subwoofer while no subwoofer can replace a mid...

cheers....

Heres how i setup my car ice:

Turn off all active/passive crossovers,bmx, and any form of sound modifiers in ur HU,pre-amp and amp..the point is to begin with true sound,no bass or treble.The sound should be totally flat.

Pop in your fav CD that you have heard a million times forward and backwards.Preferbly a song with good highs,mids and lows.By this i mean got bass,terble and midrange sounds.

Start with turning up the volume of head unit to 50% below what you normally listen to.
Turn up amp volume till volume is slightly higher than what you listen to.
Since my amp is powering my speakers and sub,i adjust the gains there till i like how the sound is.
After that,i adjust my HU settings till it sounds as superb as my setup can possibly get.
(my amp is better quality than my HU)

Sound is relative to the listener.You might not like my setup as i set it optimumly for heavy metal,but I like it.So the perfect,optimum setting is what you like to listen to.Some ppl prefer bassy sounds,I prefer more treble so i can hear the guitar solos clearly.

Have fun setting up ur system.And in the future you might want to add crossovers as they filter the sounds from your HU therefore better sound.

I set my amp to full range for the front comps set & not high pass....im play around the xover at hu from 63 to 100hz.
at 63 hz i found the tweeter give the details i want & somehow the midbass is too high only....then i put to 80hz where my midbass is ok in term of bass biut my tweeter not as the 63 hz....betwn this was tested with Lily cd album....

Wah... so complicated aaa.... need setting the xover some more. I need to learn more about this.

Agree !

Tweeter for high frequency
Mid for middle frequency
Sub for low frequency

But not advice overlap each other
