d9 sweet spot

Could anyone tell me what i need to set the output at this maxx luink for. or what the sweet spot for input voltage on the d9s are... and i have the rcas split at the amps so i guess i would need to take that into account too?? im getting about 3.2 out of the headunit into the maxx link but wondering what to set the output on it.. got 2 sets of strapped d9s... thanks

4 volt works.

test it out and find it

alright.. just getting ready to kick this thing.. just wanting to make sure i didnt set it too high.. guess i could start at 3 ish and work my way up..

They need to be strapped @1ohm!

do the d9 really work well strapped. i have always ran mine one amp to one sub?

Yes! They work great strapped. If you set them up right.

got them strapped @ 2 for daily .. and strapped @ .5 for burps

having trouble with oscope though... got all my speaker wires unhooked and set the 65hz test tone on on the maxx link.. I move my gainon my master amp lower and voltage goes up....? Then when i get up areoung 54V it just shows question marks? and never goes into clipping.. first time using an oscope.. maybe there is something im missing..

i got it i think.. got a cheap ass velleman oscope.. need some resistors i guess.. thats what allan told me.. Ijust set em at 170V for each pair until i can get to radio shack..

Are you doing music or burps. Go with full gain on burps.and run them dirty! Slight clip for music

both.. ima play em daily and probly sb @ 2 strapped and burp @ .25 .. just takes a sec to rewire.. im running them clean for music and slight clip for burps.. whenever i get some resistors to where i can see where those points are... try to get this thing going for OKC,,. got alot fo class between now and then

.25 not straped. They wont play ...

ya.. i meant .5 strapped.. .25 per amp

Sorry to threadjack, but ...

@ Chris, I know it's dumb, but as a SB guy, I don't know the mechanics of burping. Could you clarify "Go with full gain for burps"?

Best guess:
Crank the gain on the amp to MAX.
Set the HU to send a strong, but unclipped signal (~3/4 volume).
Roll in with the bass knob.
Roll out, just after the dB number levels off.

Is that what you do? I assume you use test runs to learn you how well the amp handles clipping and heat.

Dirty all the way!
Gain cranked
loud on
bass boost on
Sub control up
Roll the volume slow but not so slow you loose all your voltage.

do the d9 really work well strapped. i have always ran mine one amp to one sub?

agree with george

also chris thats some pretty sound advice and it sounds like you got that from a guy thats pretty good with the d9's


chris is correct the d9's i ran were as dirty as a whore on an early saturday morning baby

take that fornicating oscope and sell it i hate them i mean if your running 100k watts then sure you wanna be clean but not me ima dirty white boiiiiiiiiiiiiiiiiiiiiiii

well subs smell like ass.. only got it cranked halfway playing music strapped @ 2 ohm and it smelled so strong i expected to see smoke.. just glue on the new subs?? I dont run many sets of new subs...

Hot coils have a very distinct smell. Burp the Dung Pile out of them but be careful when playing music, if you smell the coils turn it down so they can cool.

I wouldnt be worried about the smell on the new ones.

The coatings on some coils like to make smelly's

ya.. i used to get alittle smell out of my mts after a SB run but they have no ventilation and subs got fairly warm.. these you can vbarely feel any warmth at all when you touch the dustcap.. i was getting ready to do a few test burps but was nervous of the smell when im putting that little of power to them.. thanks for the input

Yea .. this guy knows what the. F uck is going on!
But when you want 2 amps per sub strap them bitche's

i did a few burps in town just to get an idea.. really need a place to test.. but didnt mess with any settings and did 153.5 @ 48 hz strapped @ 2ohm on the glass... not ready to wire it down yet.. not a bad start.. still got a lot of testing to do ...

Not bad! Throw that shi t on the floor and give us some outlaw scores! Lol

yep.. i wish there was someone around here close that knew alot of stuff about this.. hard to explain stuff over the phone and get anything worked out.. look fwd to meeting some people at IFO and see what they think about what i got goin on

pretty sure my coil came unwound on 1 sub... took all of about 2k watts of clean power and 5 burps to fray an atomic apx 18 coil

coil is gone.. i pulled it out.. so much for the burp the hell out of it method.. took all of 5 well spaced out burps to blow it.. even ran the a/c between a few burps

Sorry to here that. Must have been a bad coil. Id try to get a free recone out of them, unless you think it was your fault.

i wish it was i would know the problem.. i have went through my wiring twice while talking to alan hall on the phone.. i checked it ten times before firing up.. thier site says they are good for 15k on burps im pushing 1/5 of that and even set the amps on the conservative clean side... just makes no sense.. i called them waiting on them to call back... even during burping i felt them a couple times and were barely warm...

Call joel! He is sending me 4 quad ones. I want to be on fresh cones for OKC.
