Night time bump.

Bump

I'm trying to determine enclosure specifications for a pair of 12" ZV3's for my car. Planned power is a pair of SCV-3000's strapped at 1-ohm. I've never had the opportunity to play around with any Sundown drivers bigger than the SA Series. I did just finish a box for my girlfriend's X-12 which called for a considerably larger enclosure than what I am used to for your average 12" driver but wasn't sure if the rest of their mid-to-upper lines all preferred larger enclosures. Their website recommends 2.0ft^3 per, but i'm also putting more than 1500 watts to them. Note: I have already searched the forum to no avail. Any help is appreciated!

No, I recently acquired an NS-1 in a trade for my Crescendo BC5500 plus $300 cash and it kept going into protect during gain setting on the initial power up. Long story short, I literally did an amplifier swap from the 5500 to the NS-1, everything in my car was correct. I shut the car off, turned it back on, and as I was turning the gain up it would go into protect again. I cycled the ignition and tried a third time, amplifier sparked in the vicinity of the input section, cloud of smoke rolled out of the case, and the illumination on the amplifier went out. I pulled the amplifier and tested every wire. At volume 28 (maximum unclipped on my Kenwood Excelon KDC-X397) I get 4.01-4.06 AC Volts on my RCA's. I have two runs of Rockford OFC 1/0 for power and another two runs for ground, all front to back, with three matching Shuriken's in my trunk. So a bad ground can be eliminated. And the following morning I hooked up one of those $100 eBay Shark amplifiers, set the gain with zero issue on the same oscilloscope, same power and grounds, same RCA's, and same remote turn-on, and it is still in my car now playing away on my XL's. It was brought up to me by an outside party that my problem was that the amplifier would only accept up to 4V inputs according to the manual, and this is why I blew my NS-1. As I referenced the owners manual, the only "4V" mention is in the troubleshooting section saying that if I have 4V DC or greater on my RCA's, it will protect. Well duh, 4V DC will protect an amplifier. RCA voltage is AC, according to the reference he was trying to make. It is also clearly printed on the NS-1 casing at the gain adjustment that it will accept from 0.2 to 6.0V. I just wanted a neutral party to verify, in case there was an RCA voltage issue I was not aware about. (P.S. I received the amplifier in rather rough condition, quite worse than what was described, but I am in such a time crunch for PA MECA States that I was willing to ignore the mis-described condition as long as it functioned properly, to answer the question as to why i didn't send it back immediately...)

Anybody happen to know what it is?

Correction, I meant 40Hz. Whatever it is SUPPOSED to be. It comes with a damn manual which I wasn't looking at so it's hard to fuck that up. Like I said, it was a while ago. And if 40Hz is just the industry standard then that makes sense.

I had my T2500-1bdcp set with my buddies DD-1. I never had an audible issue. Then again, clipping isn't audible. He has recently decided to sell his DD-1 and buy an o-scope because he didn't feel the DD-1 was as accurate since the DD-1 sets gains off of a 50Hz tone whereas you can look at a range of frequencies lower through the scope while setting gains. Sp basically the conclusion was, although there is "no clipping" at 50Hz, there was still clipping present at other frequencies since he burped and played music in a lower range. Now I don't know how much of a difference or how big of a difference it really makes. I'm just inputting the reasoning I've heard that actually seemed logical to me that maybe I could get a reply or even an answer for as opposed to this repetitive amplifier protection issue. The protection claim can easily be set aside regardless of reasoning because it could be so many other things. And the friend took second at MECA world finals this year in S1 out of his trunk and it was his rookie season. I'm not bragging for him, I'm just saying that he has done A LOT of research in the past year so he based this season's knowledge off of things actually relevant today to base his judgement. Edit: Jumped from phone to PC, typing on a touchscreen with big hands is a pain, ****ing typos.

I kept seeing talk on this but never clicked it in case I was just going to get my hopes up... lol Good grab! I'm tuned in for sure. Tons of room to show all of the detail that goes into a large scale build. I'm gonna go ahead and bookmark the official build thread for reference when someone tries to tell me that a big build isn't all that much work.

35Hz would be a real safe number for those drivers. I've done installs for friends on about 6 different SA-15"s. I like to tune lower. But 35Hz has always worked out well. It's also what Sundown recommends.

Everything I have heard about Explorer's basically relates to transmission issues. I would definitely come up with the extra cash to just get yours rebuilt, especially if it is in the wife's car. Either way, that's still a damn good deal overall for what you will be using it for!

Andrew give up. It's you, Dustin, Joey, and me anywhere around us. Nobody else with an SMD, CACO, ROE, CA, DSBP, or D4S account within a reasonale drive of us. Lol

I would "like" this, if my like button worked.

Not this guy again... lol And Andrew, stop posting so much or you're gonna pass me.

Good point... Depth will be an issue. Whatever you end up doing, roundovers would definitely not be a bad idea. What kin of numbers were you seeing with your current port orientation?
