Looks good !

The amps are reliable, produce at least rated power on 12.8v, and sound great -- everything and amplifier needs to do. Good warranty coverage and support (if needed) are also provided.

I clamped the SAE-1000D on my bench setup: Pyramid 50 Amp Power Supply Kinetik 2400 Battery Duralast 1000 CA Battery Fluke AC current / voltage meter Sears DMM Test load used was 2x SI Mag D2 12" all coils in parallel for 0.6 DCR with a rise to 1.08 ohms. Voltage = 32.19 Volts Current = 34.6 Amps Supply = 14.4v rest dropping to 12.5 volts Power = 1113 Watts I know I had alot of people asking about this, so there it is!

So I got the v.1 Nightshade up to 155.9 dB today on a 16v system -- right at 9.8kw clamped power. Used a slightly different coil but the cone / spider were the bone stock Nightshade parts... no pole plug of any kind used either. Not quite as good as the NS v.2 -- which did 156.1 on 12v on the same amps / same load... anxiously awaiting putting the v.2 in there on the 16v system I am hoping for 157+ from it ! Crappy pics of the sub... but I got the score : The coil is like the NS v.2 coil but only 50mm long... kind of a mix of the v.1 coil and the v.2 coil

You have a pair This was a v.1 Nightshade. In a few days I'll have 16v numbers on the v.2

For comparison sake... I built two v.1 Nightshades... the one with the actual production 50mm coil still got up to 155.5 dB... I was testing for differences in the other changes I made to the coil for the v.2

His diagram is a bit confusing but I think he may have it correct... if the left side of the box (coil) is + and the right side is - then he has it in parallel. It is a matter of a few things: 1) Needing larger power wire 2) I read on SMD that he also changed woofers -- the new woofer may not perform as well in the enclosure 3) Maximum gain in theory is 3 dB anyway -- which to the ear is only deemed around 30% louder (10 dB sounds twice as loud even though 3 dB is double the pressure)

If you have it @ 1 ohm you need 1/0 wire.

We had too many sticky posts... so this thread will simply link to the power testing threads all in one post: ONLY CURRENT MODELS WILL BE LINKED. UPDATED SAZ-1000D and new SAZ-2000D threads coming soon. * SAZ-3500D Power Testing * SAZ-1500D Power Testing * SAE-1000D Power Testing (SAZ-1000D numbers are withing a few %) UPDATED 7-20-09

I have alot of plans to offer more choices for subs... we will have a full line. E Series - 400 watts SA Series - 600 watts (8" 400 watts) X Series (name pending) - 1000 watts Z v.2 Series - 1500 watts NS v.2 series - 2000 watts So... five lines to choose from... and eventually an even larger driver than the NS v.2 for six lines total. I am also working on alot of things for amps smaller than the 3500D... but I am not making any announcements yet.

I thought about doing a 7k as alot of people said they wanted one... but nobody was willing to put money down. The 4500D is all I am doing for a bit... eventually I will go bigger but improving the "smaller" products and expanding the sub lines will come first.

Hey guys... I had to strengthen my SPAM filter today... finally got to the end of my rope on it -- I had 300 SPAM e-mails over the weekend and it's a pain to sort through and find the good ones I need to answer. SO... starting today if you e-mail me and DO NOT hear back within 2-5 days please post up here so I can make sure my SPAM filter isn't TOO strong.

Only four D4s left... still a decent bit of D2.

I don't know when it will be open yet... depends on orders from International accounts.

SSA may just need to update their store -- shoot them an e-mail

6" deep

1) smuller answered the fuse question. 2) The manual says that but they are indeed rated at 12.8 volts. 3) There already is a Dual-2 model -- came out several weeks ago Specs are on the site now for it.

E-Mail me -- I don't use PMs on the forums. I am selling my six.

Finally got all the product pages updated with professional photos! Also updated the Nightshade pages with correct T/S specs, box specs, mounting specs, etc.

Probably towards the end.

I may or may not go... gonna play around w/ the Jeep a bit this weekend.

Yah, there are some left... lead time is like a week to assemble if you order.

Looks good

Yes, we are indeed closed Saturday and Sunday and are not here at 2 AM

REGULAR VOLTAGE TESTING: Testing by Loyd Lowry. results from the sundowns... Test Vehicle.. mine.. 05 aveo.. RMS clamp and dmm, as seen in the 12" test session.. This testing includes recent results, and not so recent.. woofers used.. 2 Mags (1.9 dcr per coil), 2 FI Q 12's (1.4 dcr per coil) either used 1 sub or both of the pair for loads.. pure 60hz sine was used to tested.. just under audible clipping 1 amp, single 1000ca everstart maxx, factory alt 4 ohm nominal = 518 watts @ 88% efficiency (voltage fell from 14.3v, to 14.0v) 2 ohm nominal = 948 watts @ 85% efficiency (voltage fell from 14.3v, to 13.6v) 1 ohm nominal = 1510 watts @ 78% efficiency (voltage fell from 14.3v, to 12.4 volts .5 ohm nominal = 1615 watts @ 72% efficiency (voltage fell from 14.3v, to 11.8v) .35 ohm nominal = 1748 watts @ 67% efficiency (voltage fell from 14.3v, to 11.4v) amplifier was protection happy @ .35 with tones, and some music. IMO.. one 1500d should be limited to 1 ohm nominal use in factory electrical systems.. for the sake of the car.. not the amp now... to have fun with some juice.. 1 amp, single 1000ca everstart maxx, 1 Eagle Picher 12a5000, factory alt 4 ohm nominal = 520 watts @ 88% efficiency (voltage fell from 14.3v, to 14.1v) 2 ohm nominal = 960 watts @ 84% efficiency (voltage fell from 14.3v, to 13.7v) 1 ohm nominal = 1635 watts @ 75% efficiency (voltage fell from 14.3v, to 12.8 volts .5 ohm nominal = 1890 watts @ 71% efficiency (voltage fell from 14.3v, to 12.8v) .35 ohm nominal = 2245 watts @ 65% efficiency (voltage fell from 14.3v, to 12.8v) amplifier did fine @ .35 with tones and music with the added battery 2 amps strapped, with both batteries (for the sake of not typing it over and over... voltage drops from 14.3v, to 12.8 the entire test... lol 4 ohm strapped = 1900 watts @ 82% efficiency 2 ohm strapped = 3150 watts @ 72% efficiency 1 ohm strapped = 3740 watts @ 68% efficiency .5 ohm strapped = 4425 watts @ 65% efficiency .35 ohm strapped = 5415 watts @ 62% efficiency amps would only tolerate a VERY short burp @ .35.. -------------------------------- HIGH VOLTAGE TESTING: Testing by Sean Belanger Here's the setup, a pair of Sundown Audio SAZ-1500d's strapped at 1 ohm. In the box used in the test (a single Funkin Audio MF12, dual 2), rise went from 1 ohm to 2 ohms during play. Here are the results: Notes: * Highest power on 16.0v rest was 4663 watts on 14.3v * Highest power on 16.5v rest was 5136 watts on 14.3v * Highest power on 17.9v rest was 5677 watts on 15.5v * 84% efficient on 15.0v and 180 amps of draw per amp There was a 10% increase in power starting 0.5v higher with an ending voltage being the same. There was another 10% increase when starting at 1.4v higher and ending 1.2v higher. This would tell me that a lowest voltage over 16.5v likely wouldn't be much of a gain from below that. No matter how ya look at it, tapping the 5700 mark on 15v isn't too shabby from a pair of 1500 watt amps. --------------- Regular and High Voltage Posts Consolidated on 10-23-08 Original "High Voltage Thread" Here: http://www.soundsolutionsaudio.com/forum/i...?showtopic=7117
