No opinions or suggestions? Hey at this point I am listening. It has gotten a little expensive so I'm open to some expert advise.

Ok Jay-cee, Let me start from the beginning. I have a 2004 Ford E-350 PSD van. The van has originally two 850 amp batteries in parallel. When my son and I installed the system, we used zero gauge wire to connect two Kinetik 3800 batteries to the original batteries. I have two FI 15 BTL's wired for one Ohm. I am using two amplifiers ( Hifonics Brutus BXI2610D) each one driving one sub. The product info states that they put out 2600 watts @ 1 Ohm. We also installed an Excessive amperage 250amp alternator. The system worked great with no problems at all. It is pretty loud for our small Island so I was happy. Leading up to the end of the alternator...... We were standing in the parking lot at the airport waiting for my wife and daughter to come back from a shopping trip to Miami and of course every once in a while we cracked the stereo and laughed at people jumping aside because of the massive bass. Went to greet the wife and daughter, got in the van and drove off. All of a sudden the alt light comes on and I can see it is not charging at all. Being on a hot tropical Island I wasn't about to turn the AC or light off so the wife would start bitching about messing with the stereo,etc,etc. Got back home after driving for about 20 minutes and the van even restarted just fine. Good thing I had the additional batteries. I spoke with Nate at Excessive for a lengthy period trying to pin point why the alt failed. (I now have a pretty good idea) The thing is I want to be able to play that thing as loud as I want for as long as I want. So.....now we are getting to what I ordered next. Spoke to Nate again and he is sending me parts to make the burned alt into a 350 amp alternator along with a new 350 amp alternator. Got in touch with friends in the States that own a Ford dealership and got him to send me a bracket kit and wiring diagram so that I can install a second alternator. To have a bigger reserve, I also spoke with Diane and Mr. Mckenzie at XSTATIC LLC who is sending me two BATCAP 4000's. I was thinking to run both 350 amp alternators and add the two Batcap 4000 to the rest of the system. I am almost afraid to ask for an opinion now but what the heck. Let me hear it.

Ok fair enough... I did get a little frustrated and am sure there are plenty of knowledgeable people here. My apologies. I just applied the theory to be sure that worst come I would at least have enough battery reserve to give when needed. I think I just asked too much of the alt for too long a period. I ordered two 350 amp alts, a bracket kit to install both. On top of this , also have two batcaps 4000 to separate them from the normal car batteries. I'll see to read up some more. thanks and have a good weekend. JR

Haha this is hilarious, we have no intelligence at all but you think your system puts out 10,400 or 28,800 watts. Thanks for the laugh of the year, that took the cake for the funniest shit I have heard all year long. Well good luck buddy and have fun, I doubt anybody is going to email you either. Im sorry that we ask questions to understand what could be the problem instead of jumping to conclusions like other people would and make assumptions. If you were smart you would contact the company that made the amp and talk to them about it since it failed so early. aww you beat me lol but: a round of applause to jay exactly!!!!!! more interested in trying to be somebody instead of a helpful answer. Read the rest of the posts where I corrected that you moron. I guess you had someone install your system cause experience or knowledge you seem to miss. The day you can get to two FI BTL's fully loaded you let me know....LMAO...what a peon....lol Man...I'll be showing people these posts...hahahahaha LMAO...you are so right...Thanks for the laugh....

You know what. I have not seen an answer that is any help at all. Lots of people here wondering if this or if that with only the lamest remarks I have seen in a long time. Even the most simple laws of electronics are not known here. My God, I did not have dead batteries or any other problem. The alt just quit. thought I could find some intelligent advise here instead of these stupid observations I already know. I thank you all for all your help, wish you all a good weekend but I'm going to find a forum with some more educated people...lmao want to mail me directly with some other dumb ass or stupid remarks, please do so at [email protected]

That is great. Thanks for the help.

REALLY??? so Volts(V) x current(I or amps) does not give watts? hmmmm I'm really at a loss now. As for the alt having to charge a not drained battery pack, I guess then it would not have to work so hard huh?! Wonder what the regulator in the Alt does then. Yah...I've done some research. Thanks for your help. Have a good weekend.

Ok great..did make a mistake in the math. The way the batteries are hooked is as follows. Underneath the van there are two FORD OEM 850 dry crancking amp batteries.I ran a cable up into the rear of the van right next to where the other batteries are, maybe a foot and a half away from them, I installed two Kinetik 3800 watt batteries in parallel with the first two. From the two kinetik I have zero guage running to the Amps.One amp connected to one Kinetik. When everything was running I had No diming. The system did not warn me of anything. It was all running great untill the alt just quit. There is one thing that the mechanic did change. He replaced the smaller pulley back to the stock one other wise the belt (which is not in stock on the Island) would be too large.

This is how I got my numbers. Two 2600 RMS amps = RMS/ 0.707 = Peak in this case 2600/0.707 = 3,677 watts x 2= 7,355 total watts peak. Sorry not 10400. the 28000 watts is what the batteries are supposed to have together. two kinetik 3800 watts = 7600 watts plus the two 850 amp ford batteries is 850 x 12v =10200 x 2 =20400 watts. total 28000 watts. I just want to know if I got a bad alt or if there is something else that I am doing wrong. I have no problem with a bad Alt...it happens...most impoprtant is to know what happened. thanks and have a good weekend, JR

It could have been a bad alternator as well. This is why I am asking these questions. I had installed years ago a new Ford OEM alternator and it quit within a month. So it would not surprise me one bit. It happens. No problem. I just want to identify the problem. Being on a small Island doesn't help in terms of knowledge... Thanks. JR

What I meant was that the subs are not connected together. They run of their own amps. I have the Brutus 2600 watts Rms amps. 2 brutus 2600Rms amps run off of the batteries. The way I got to the total watts is simple. I have two Kinetiks 3800 watts as stated on their website. The ford has two 850 amp batteries. 850x12v =10200 watts x 2 =20400 + the two kinetics =28000. as far as I know I x V = watts. These is what the batteries supposedly hold all together. So why all these questions about equipment instead of a helpful answer. Thanks.

Hey hola you too..... now let me go post my problem and see what kind of edvice I get. Gracias chicos.

Hello, I have a little problem and don't know for sure how to solve it. I have two FI 15 inch subs and am running two 5200 watt amps. They are wired seperatly but are drawing power from the two 850 amp batteries originally in the van and two additional Kinetik 3800 batteries wired parallel. The problem is that I burned up a brand spanking new 250 Amp alternator from Excessive amps. I am new to this and don't know if trying to draw the 10400 watts from the batteries overworked the amp or what... Any idea what I have wrong that I need to fix?? Many thanks I appreciate it.

Many thanks guys. I joined a few audio forums because I have a problem with a setup I recently installed. Within a week a 250 amp alternator was fried. I am trying to figure out of it was just a bad altenator or that my setup is causing it.

The amps are Brutus 2600RMS the Fi subs are 15 inch all options that were possible. Heating ring,double voice coil,etc,etc. they were built for daily. Although I don't run it at much more then minimum normally when just playing music. The additional batteries are hooked up in parallel with the existing two 850 amp Ford van batteries. The alternator was a 250Amp alternator and yes I did speak with Excessive amps. He said he has been building alternators for over 10 years etc,etc. the usual and expected reply...Since I am in the Caribbean and a good 2000 miles away I don't have the luxury to argue much. Shouldn't the bigger alternator be able to take care of the additional batteries? I am now installing 2 other batteries (BATCAP 4000), a 350 amp alternator and if I can locate it a bracket kit to run two 350 amp alternators. I don't know what else I can do. I would appreciate your input on this. Many thanks.
