Dang...now imagine what kind of numbers the AT 7000.1 would do!3 points

ok, just because i don't konw if this video is going to come up for someone else BEFORE me, i am going to put the contest to an end. Here is the video, it should be live, when it becomes live Please do me a favor, LIKE, SHARE and FAVORITE this video! I want to keep doing it and i am totally willing to keep trying to give the amps away, like a little FREE lotto. thanks for playing!!!2 points

This week's Amp Test Tuesday, in case you didn't notice by the title, is the CT Sounds AT1400.1d. First impressions. A very sexy amp. I really dig the white, it is a nice change. I also like the lit up logo. I love the bass knob with built in amp turn on/off. there was one little issue. The box has ratings on the back that basically state it is a 1400x1 @ 12.8v amplifier. The book says 1200 watts and gives no voltage rating. I tested the amp with my 12v bank which consists of 3 fully charged XS Power XP3000 Batteries. I also tested it with my 14.5v bank which, as you might already know by now, is 3, fully charged XS Power D1400 batteries. I use a single xs power, HF battery charger on each bank. They are only 15a. Not really much a "power supply", but they do keep the batteries topped off in between runs. Here is a link to the charger i use (the HF1215 and 1415). http://www.wccaraudio.com/xs-power.html?cat=10 I know in the past i referred to those chargers as 10a but that was a mistake. I don't know why i said 10, total verbal "typo". Anyhow, the extra 5a isn't making a drastic difference, it just charges the batteries up that much faster. If anything, it gives the amplifier 5a more of a chance to make its number. Picture a battery bank with a 15 amp alternator on it. Anyhow, who wants to play a game? Results @ 12.8v Power supply: 3 XS Power XP3000 (Fully charged Once for all tests) Impedance: 1ohm Certified @ 1% Distortion: x,xxx Watts UnCertified @ Clipping: x,xxx watts Dynamic Power (RMS) @ Clipping: x,xxx watts Results @ 14.5v Power supply: 3 XS Power D1400 (Fully charged Once for all tests) Impedance: 1ohm Certified @ 1% Distortion: x,xxx Watts UnCertified @ Clipping: x,xxx watts Dynamic Power (RMS) @ Clipping: x,xxx watts ***** PLEASE READ BELOW ***** Add up all of those numbers together. Yes, all 6. If anyone here guesses the exact number, i will give you the amplifier. I honestly do NOT want to part with it. I like it. But if you guess the number i am looking for, it will be yours. As a bonus, if you are a GOLD, Silver or Bronze supporting member of this site, AND you guess the number, i will personally buy you a matching mids/highs amp to go with this. If you are a GOLD supporting member, you get the mids/highs amp, the 1400.1d and will also get a CC-1 Crossover Calibrator as shown in the video. Regardless, to play the game you must be a member of this site (supporting or not), and post your guesses HERE. Not on Facebook or twitter, but here in this thread. If you are NOT a member, its easy! use "facebook connect" and join almost instantly! now, on with the pics! See you guys on Tuesday!1 point

this has been on my garage shelf for about 18yrs now, going on 19. If we were playing a game called "i bet i have something you don't have", i might win No, i won't drink it it has sediment at the bottom, if you look in the next pic you can see it . Not only that, i don't wanna crack it. I would throw up on the spot. Oh i can still pound back a FRESH one, but this one has rode it out too long and is probably pure poison.1 point

Get hands on an 'Ol Orion 225 HCCA & rock that down to .25-ohm. Let us see what we were working with 20'ish years ago ...1 point

D2. wire the positves together then to the amp. then wire the negatives together to the negative on the amp1 point

This is your first post? you failed Be easy on the new guys man. First posts aren't try outs or anything. Nice try Willem. Welcome to the forum.1 point

Should I buy the 1200.1 and sell my AQ750? :\ Thinking so.1 point

I can't even imagine!... Now, hugs my AT1200.1D.. I loved that amp before, I knew it was strong. Had no idea that it was quite that strong though..1 point

Sorry, didn't see where he said that. Went straight to the end to try to get in my guess. At work so caught this by chance.1 point

The shipping staff has let me know that almost all pre-orders should be done after today. All that remains are some pallet orders for distributors and maybe a few NON pre-order customers.1 point

A) 0.004Ohms x 200A = 11.8V 11.8V - (0.002Ohms + 0.002Ohms) x 200A = 11V C) 11V x 200A = 2200W D) 2200W x 0.7 = 1540W1 point

here ya go Steve. got a bottle of tequila that's about 24 years old (give or take 2 years). 80 proof, never opened and worm on bottom still. growing up i always remembered seeing this bottle in my grandparents cabinets, usually way in the back behind the cereal. story behind it is my grandmother never believed that a worm can come in a tequila bottle so my grandpa and dad drove to either Mexico or Texas to get this. ( That's what i was always told) i just have it sitting in the cabinet. might open it one day to have a toast to old memory's to my grandpa. has Mexico liquor bottle molded on the bottom and the numbers 8 and 7 there under it.1 point

Wow... of ALL the topics I said I was going to talk about, this is the one that got you guys all fired up? Oh man.... just wait until we talk about clamps and how AC power is measured. Let me get something out of the way, when I said it CCA is "not okay", I am not saying your car is going to burn to the ground like all of the houses built in the 70s that used aluminum wire. I'm saying it is one more thing in our hobby that we don't need. Here is the indisputable fact, not opinion: You need roughly twice as much CCA and it costs roughly 1/2 as much, and gives you twice the number of terminations (which is CCAs downfall). So what is the point? Why it is "not okay": It is not okay because IMO you are getting ripped off. Same problem I have with overrated equipment. CCA costs roughly 1/2 of OFC, yet aluminum costs 4 times less than copper. Hmmmm. Someone please explain to me how that math works out. Yes someone is cashing out at your expense, and since the manufactures of this wire (China) are ca$hing out, of course they look for ways to cash out even more. Example: Once I was asked, at a previous employer, to test 3 different CCA cables all 1/0 AWG. 1 of them was the current one we were selling, the other 2 were cost saving versions. What? Isn't CCA, CCA? Nope. Of the 3 I tested, the worst one had DOUBLE the resistance of the best one, and saved us 30% on cost. Can you guess which one that company started to sell? The numbers I used in Video 1: DC, were numbers I looked up for "standard", "legit" CCA, not numbers I tested. The worse of the 3 I tested had double the industry standard resistance. That being said I'm guessing the situation is even worse that what I said. But I only talk fact, so I used the industry standard resistances. Don't worry real testing is coming, I'm just waiting for the cable I ordered to arrive. Side note: the "lanes" are not a magical place, and I have been in the lanes plenty of times myself. I'm not sure everyone is understanding the conservation of energy here. If you lose 500 watts in a cable, that's it, it's lost, gone. Well where did it come from? Your alternator(s)... and 500 watts/14V = 35.7 amps. So if you are cool with losing 35 amps per each run of cable that is losing 500W, then ok. Fine with me. Seems like you probably spent some hard earned cash on those high output alts to just throw away 35 amps, but whatever makes you happy. I know the guys "in the lanes" do some extreme work to their vehicles. I've been there, I've done the 3 AM builds the night before. Some of these extreme vehicles use multiple high output alts, custom built mountings, 1000s of pounds of MDF, metal, batteries, etc. You guys go ALL OUT on these vehicles. It's awesome. But then you don't on the wire? Ok 5 runs of CCA is less resistance than 2 or 3 runs of OFC. But 5 runs of OFC is way better. I just don't get it. Let us also note that less than 1% of people with systems compete. So what about the other 99%? I am going to try to hide 2 or 3 runs of CCA under the carpet of my Jeep when I could use 1 run of OFC? Hell no. You already bought a mile of CCA and you are running it? That's fine, it works. Make sure it's terminated good and run it. It's just not as good as it could be, and it is just one more thing in our industry that has gone the way of quantity vs quality; and that is the most disturbing part for me.1 point
