I know a few ppl burping that low. But just because someone else does it safely though doesnt mean it wont smoke for you.
yeah, i know that, just want to try and get an overall view, that out of the people that do burp that low they are generally ok. i know power supply is a big thing, so thats kinda what i need to know as well from the people going that low. thats before any box rise too.
-
has anyone burped these amps that low? any problems doing so?
ill have upto 7 XS D1400 batteries to use with the engine off (dont have alts to support high charging in this vehicle)

Hi guys, im moving from streetbass and ground pounding over to DB Drag next year and im after some guidence on a box. want a SSnw box
im using 2x Level 5 M1 18's (dual 1.4's) and 1 Sundown SAZ 2500d (will use a pair of them for competition)
now im putting this into a van, so not really short on space.
my plan is to start big with the box, and shrink it to suit.
my questions are, what sort of size box's have people used with this sort of "low power" im going to be using? and how much port area?
i dont want loads of people saying dont bother, not enough power etc, its for fun, to keep me amused to see how loud i can get with the equipment i have. i only want to run one amp daily as its a daily drive and power supply is crap, but i dont mind going into low voltage for testing.
Just so you guys know, this equipment has come out of my streetbass car, with 14v xs batteries, and with this equipment i had a 157.6 at 33Hz, so i have the potential to get loud
Thanks for any help

So, long time without an update on here! i made a few modifications for strength in my cabin
steel box section down the centre of the roof braced with steel poles front and back
that improved my scores, and took me up to
154.3 @ 40 Hz
155.3 @ 33 Hz
155.2 @ 25 Hz
153.2 @ 20 Hz
and peak of 156.0 @ 31 Hz
Then came these lovely XS Power D1400's. 7 of them, to run just my 2 SAZ 2500's.
left my dual inputs off for now while i wait for new buss bars and a custom fuse holder, but there is a lot more 0AWG to go in there!
and with those pupies in the back, i hit these numbers!
and a nice new trim pannel for the boot to make it look pretty.
Went to a show at the weekend, and walked away with first place in DB Drag, with a 153.something at 29 Hz. peaking low sealed up lol! i also walked away with first place in Propper Droppers, and EMMA (European Mobile Multimedia Association)
Now to start searching for that 158........

well whatever the power increase i got, it worked i had a 1.6db gain on my peak frequency, and it took me from a 156.0 to a 157.6. AWESOME!
-
maybe not on music, but what about burps when i compete? if for example i had box rise to 1 ohm, what would one of these amps produce with this voltage?
-
Ratings :
2500 @ 1 ohm
1200 @ 2 ohms
600 @ 4 ohms
----------
Testing :
Wired @ 1 ohm in Derrick's Explorer :
1690 Watts
21.4 Amps
78.97 Volts
3.69 ohms Actual
Wired @ 0.25 in Derrick's Explorer:
3360 Watts
63 Amps
53 Volts
0.85 ohm actual
Around 14v actual voltagclamp tests from a 2500. should do more than rated as it is, so should both should have been be doing over 2.5k with my 12v batteries??
-
amps are wired to 0.7 5k from each amp? really that much?
-
7 of the batteries, and a single 210 alt.
2x 2500's
-
what sort of power can i expect from these amps with these batteries?
-
its at 1.4 cause the subs are dual 1.4's.
will be wired to 2.8 each then down to 1.4, currently have a 3500 on each sub, but want to drop power. and i just fried the amps
-
by whats on paper, hence asking for the rated powers.
-
in the format i compete in in the uk, i need below 6k RATED power, what would the NS-1 do at 1.4ohms on paper?
Thanks
-
Do you have info on the mounting depth of these? and level 6's. would be real helpfull if you do
-
Rusty stated summer when i was in the phone with him 3 weeks ago. He was in the proto stage iirc, and wanted all other m2 stuff caught up with before doing the fives. Somthing about 2 protos to test out but not sure if to rhat point yet.
Its Summer time here now
any news on these yet? or still no?
if you havent noticed, im kinda impatient.....

Ive been following this build on a u.k forum.Well done on the scores,why do you test at different frequencies?.Never seen pd before.
Those back seats look spot on ,great idea.
All the best for the coming year.
We test different frequencies to see who has the best/loudest range of frequencies. The frequencies you find in most music bassers use over here. These are the averaged out to get your final score.
It's also read from the headrest so you get an idea of what your ears are hearing when you play music
I reckon a few of you guys should test PD style
-
So i went to a loca meet last night and got tested in the PD - Propper Droppers format we do here in the uk. get tested at 40Hz, 33Hz, 25Hz, and 20Hz. then your peak frequency. then all scores are averaged to give you your PD score.
My scores-
40Hz - 150.0
33Hz - 153.7
25Hz - 154.5
20Hz - 153.2
Peak was 31Hz - 155.6
PD Average - 153.4 Db
pleased with my scores on the low end, but i need to up my 40Hz by like 3db...
more work on the box i think
-
verry nice build!!!
hope to see this car in Mod Nat. we're from belgium and we'll come to that event to.
hopefully we can compete, because we'll be there also with our walled installation in the Propper Dropper section
Yes I will be there!
Ate you coming with the General?
-
I wish they would stop teasing us!
-
It does't exist.....yet muhahahahahahaha!!!!!!!!!
I thaught testing was being done a while ago, need a sub to do the testing right? Lol
i heard you were/are supposed to get the first two protos....
I thaught they were being tested a while ago, need a sub to test right? Lol
-
Europe has a distributor as well iirc
We do, but he has no information yet, which is why I asked here
It does't exist.....yet muhahahahahahaha!!!!!!!!!
You have a pm
Edit: no you don't, I keep getting an awray error? Can u pm me please so I can reply to it
-
I know these won't be out untill the m1 motors are all sold, but is there any rough idea on when these will be out? I'll be after a pair in the UK, so if someone wants to pm me a ball-park figure of expected costs too that would be great
Thanks

So i have done quite a bit on this lately, moved the amps in to the rear, added another 4 runs of 0 gauge, now have 4 live and 2 earth.
dual inputs to the sundown amps, done some box mods and had the level 5's reconed with AR cones, and carbon caps and direct leads.
and the result of all my work-
not bad for 2 18's and 7k
mic was on passenger headrest with drivers door open.
-
Ok thanks. I wasn't sure how true it was, but it seems it'll help me out a bit as I'm sticking double the Rms through my level 5's. Are the AR cones stringer than the standard cones too?
The recones I have ordered have carbon caps and AR cones. Will this be much stronger than standard cones?

SAZ 2500d's at 0.35 ohms
in Sundown Audio - GREAT Amps/Subs! GREAT Customer Service!

what was your power supply like?
