Smoove

My truck is not my daily driver. When it was cooler out and not raining I'd leave it float charging all week. When it got hotter I started only charging like 10pm to 8am randomly through the week. When it hit 115 out I didnt charge for like 3-4weeks (batteries didnt drop below 12.9). After finding the charging voltage charge the other night I decided to see if the XS charger followed that chart. Depending on how often you play and charge off the alts will determine how often you need to charge. I know a couple guys who charge every night and others who charge once a week

I have an orange power cord pulled under my garage door and into the bed plugged into the charger. You can see the cord in the bottom left corner of the third pic.

Please ignore the mess. I havent fully mounted the charger yet Temperature wire to a ground Charger wires direct to terminals Battery temp and charger with charger monitor Messy temporary setup And yes I was charging higher than I should until I put the temp sensor cable on. So yes it works

Being hot as hell in PHX I finally connected the temp sensor cable on my PSC15. According to the temp gun I bought my batteries are at 97 degrees right now. They have been as high as 126 degrees on a 105 degree day. Living in PHX or some where HOT!!! Temp sensor FTW!!!! According to the chart below the temp sensor is doing its job. I am currently charging at 13.9v with almost 100 degree batteries (love the screen that comes with the PSC15).

Hey guys thanks for the props!! Yes it is true the idea came from a defibrillator. It seemed silly to me that all these guys in the db drag lanes need to have 1/2 of their vehicle full of batteries and alternators to maintain a decent B+ voltage for a few seconds. That and the fact that the amount of total energy all those batteries contain is huge and they are only using a fraction of it during their burp. It is like taking a NASCAR car to a drag race. A vehicle that is designed to go 200mph for hours on end probably isn't the best design for a 1/4 mile burst. So when you look at the way a defibrillator is used its like burping an amp. Defibrillators don't have massive power cords that need mega amps at 220V, in fact some of them are portable and run off a very small battery. Why, because they don't need to shock someone for hours at a time, just a quick burst. They just draw a small amount of power continuously during 'charge up' and once all the energy they need is accumulated they release it all at once. With the operation of the defibrillator in mind, I tried to apply it to car audio. I set off to build a prototype which was based on (2) T1500.2 output sections, I had to liquid cool the MOSFETs because even the FETs in the T1500.2's were not big enough to handle the kind of power I wanted. By keeping them very cold they could be pushed beyond their limits. (This may be the radiator ect... part of the story that someone posted). Then I needed a way to store a bunch of energy, electrolytic caps and some of the carbon based caps that are commonly used in car audio were not even close to being capable of storing the amount of energy I needed, so I used 12 small motorcycle batteries in series to get 140+ Volts. Then I built a power supply that would convert 12VDC to 140VDC to 'charge' these batteries. I got this contraption all put together the night before the Annual Rockford Fosgate Employee Sound-Off. I didn't really how much power it would make exactly, but to try to shorten this long story it ended up putting out 15,030 Watts RMS! This is how 15k Watts became the goal for a 'real' amp. The first step towards making it a 'real' amplifier was I had to eliminate the array of batteries. I began searching high and low for something that would do it. I found a company that makes capacitors for hybrid cars and large wind turbines. These worked perfectly. The caps I ended up using are 400 Farads, and there are 180 of these in the T15kW. Then I needed an intelligent power supply that could monitor these caps and add energy to them as needed, and it had to be fast, really fast if this amp was going to play music and not just a burst. So during music these caps are charging, discharging, charging, discharging. The power supply in the T15kW can charge the caps 35,000 times per second. Of course many other things had to happen like finding MOSFETs that could handle it, a way to keep it cool without antifreeze and car radiators ect. The final product met all the goals and then some. The main idea is that with this technology the amplifier can put out more power during transients or bursts than the car it's connected to could supply. Again thanks for the props, look for hybrid technology to hit our smaller amplifiers in the near future. PS if you guys would like to see pictures of the original liquid cooled proto I'll post them. This proto was eventually dubbed the D'Fibrillator. haha -------------------------------------------------------------------------------- Tony D'Amore Design Engineer Rockford Corporation So much :wackit3: :wackit3: :wackit3: in this post.

I took this vid at CES . All 5 being controlled from 1 master. I have taken my Diamondboxx to a basshead meet. Just to prove the bluetooth is that good, I set it down and then walk away.

some sort of cool grills would be cool

They sound great. got mine a few weeks ago. Wife picked the red. Then sha claimed it and told me to get my own

I love amp Dyno's. Good amps, bad amps. I wanna see them all Dyno'd. GR = 1302

M&M godfathers were in the first big build (back then) that fully got me hooked. There was tons of RF and Orion every were in my high school in the late 80's, I dont know where the love for big bass actually began.

great idea.

If the amp is put on an AD-1 and I get to see what it actually does. It would make me feel much better about the purchase.

I went with the PSC15 cause of the recover feature and the multple voltages it will charge at. Charges 6 group 31's and a 3400 quickly. My only complaint is I wish it came with battery clamps stock. I also like having the external screen on a cable that it comes with.

This was the answer I was looking for. Badsd on your response, if I keep all th batteries properly charged regularly I should never need maintenance/de-sulfation mode. I thought it was something you just ran every few months.

Dec 2011 PHX, AZ.

Should be fine at .45 per sub sealed in that box. Sundown recommends .5, that difference wont be noticeable I run mine sealed at .6

Well normal charging it is. All my batteries are 12.9-13.1. And they are on the new PSC15. I wasn't sure if it was a once a month thing for recovery mode. Truck on gets driven maybe 3 times a month.

XS charger with xp3000's , non-daily driven setup How often should the desulfation/recovery mode be run?

waiting for updates............

can't wait to see how this comes out

THats great, cause my idle is 650-700rpm
