playing time..

[kana12]

3 amps. memphis 1000d, jl 6450, alpine pdx4.150. wet sounds 3 some, xxx-xs sub, ws420, 3 pairs of wetsounds xs 650s,

i have two interstate batteries, one cranking and another deep cycle.

my first question is how long can i play my radio all out with the key in acc until im dead on the water..

my next question is that i also have 2 brand new orbital gel filled batteries that are marine sitting here. can i add both of them and will my alt. be able to handle them or al least one.

[da.bell]

No, the alt will not handle all four of them being charged. And if it did, your alt would be working way too hard.

Look into a Battery Tender to maintain any additional battery that you have in there besides the two that you currently have.

[kana12]

whats that ? and can i hook them up if i just put a charger on them at the end of the day everytime? or can i run maybe 3?

[da.bell]

Well, I will leave that question to Chpthril. He seems to be the better person to answer. But I do know that the standard alt that you have will not handle 4 batteries and keep them charged. Sorry

[kana12]

3?

[da.bell]

Not entirely sure about that Not to mention you have two different types of batteries going on here.

You are funny, you are digging and digging

[kana12]

lol.. ya i know.. i cant stand not to know something

Need to know the RMS output of each and and at what Ohm's are the wired at so we can calculate the current draw. Most figure it a 1/2 - 3/4 volume as most dont play a wide open on a constant basis.

Next, need to know what the Ah rating of the batteries you plan to use. This, and the figure from above, will give you are apx play time.

Now for the wrench The batteries for the stereo will certainly be better then one Deepcycle, but I would recommend NOT adding the 2 orbitals to the one deepcycle in current use. Remove the deepcycle and use the 2 Gel's. If they do not give you enough play time, then add another. It's never a good idea to mix different battery types (wet cell lead-acid and Gel's or AGM's) on a single bank as they will not charge at the same rate. The alt will over charge one under charge the other. Even though, when 2 or more batteries are wired together, they will equalize, it's still not best for the entire system. So, go will all one type of battery for the stereo bank. Does you 06V have an Isolator? Not sure when Tige started using them. If not, you need one. If it's a Diode type (used from the factory, you may want to consider swapping it out for an ACR (auto combiner relay) like from Blue Sea. The diode type can have up to a .7 volt drop across the diodes and on a typical system, this will not be a problem (never was on mine) but on yours, it could result in less play time. But, if you use an on-board charger/tender to top off the batteries at night at the dock or home, this would be a moot point as the charge will bypassing the diode Iso.

Next, move the H/U's power to it's own switch and off the ACC position of the key. This is drawing off the "Starting" battery, although not alot, but could be enough to draw it down over a long day at the sandbar and leave you hanging. Move the Yellow and ground to the Amps, and move the red from the Key to it's own rocker switch. Moomba/Supra use a switch with a music symbol on it and you can buy just the cover for about $4.00 and pop it on an unused switch on you helm.

wow ok im lost. lots of info in another language.. so your saying dont mix gel filled with acid.

well what i was thinking is this if you can fallow me. put the two orbitsl bstteries in there but put a switch between the two orbital and the acid. when the boat running and just sitting tun the switch on so it can draw from all 4 batteries.. when its time to start the boat turn the switch off and then chrage the orbitals at the dock with a battery charger? so tha they never over load the alt. ? will that work or is that still mixing them. the problem is i just spent 200 or so for two interstate and then they gave me free replacment on the orbital.. 480 bucks is what i spent for two of them. blue tops. so i need at least another battery ?

on the system. the sub is 1000 rms at 1 ohm 1000 w. class d amp. then a jl audio is running my in boat speakers. i think they are at 4 ohm. not sure the rms then the alpine pdx 4.150 is runnin the 3 some on the tower an i think they are at 4 ohm 150 rms i think. ? i just wanna make sure i can jam my system for a couple of hours and be able to strat the boat again for a few min to recharge them

Take a spare battery with you out on the lake along with a wrench and try your experiment. Boom till you drop, mark the time, swap in the spare and head for the dock. Just hope you don't get shot or beat up by someone who doesn't like your two hours of music choices. I still have a hard time thinking its OK to blast one's music all over the lake for an extended period from a fixed location; but that's just me.

There was a thread recently discussing isolating the starting battery from the house batteries. Good reading.

You dont want to mix them in the same bank of batteries!

Not sure I fallow, but lets see. I dont see a need for the Lead-acid wet-cell anymore if you are going to use the 2 Orbitals, unless you want to use it as a backup battery for the main starting battery. This Makes for a slightly complicated setup if you want the whole system to be charged by the Alt, or real simple if you want the stereo bank left as a stand-alone only to be charged by AC back at the dock. When you are chill'n with the tunes on and engine OFF, you want the stereo bank disconnected from the starting bank (kinda reads backwards above) and when the engine is running, you want the battery banks connected, but through an Iso/Combiner. If you were drawing from all the batteries when engine is off, then you will have a dead starting battery when it's time to head home.

You've got options, so it comes down to how you want the system to work.

on the system. the sub is 1000 rms at 1 ohm 1000 w. class d amp. then a jl audio is running my in boat speakers. i think they are at 4 ohm. not sure the rms then the alpine pdx 4.150 is runnin the 3 some on the tower an i think they are at 4 ohm 150 rms i think. ? i just wanna make sure i can jam my system for a couple of hours and be able to strat the boat again for a few min to recharge them

With 3 pairs of xs-650's, you've prolly got 1 pair wired at 4ohm and 2 pair wired at 2ohm. Let me look at the specs and crunch some numbers.

Just looked, the JL is a 6chnl so all are running at 4ohm.

[chpthril]

Ok, here are some number, hope there right, it gets fuzzy if you dont do it every day

Calculated at 12.5v's
The Memphis 1000D will draw 80 amps
The Alpine PDX will draw 48 amps (150W's per chnl @ 4ohms, but at 14V)
The JL-6450 will draw 26 amps (55 W's per chnl @ 4ohm, but again @ 14V)

So, total Amp draw is 154, then divide that by 1/2 for normal listen pleasure, you get 77 amps draw. This number may be slightly high, as these amp's specs only showed their watts RMS output at 14.5 volts, not 12.8 that you will have when the engine is off.

[kana12]

so what kinda time does that equal.. i just wish i knew more about this stuff

[kana12]

so i also get that the two gel filled are better than the cranking and deep cycle acid battery

[kana12]

still dont have a solid anwser on playing time if anyone has an idea.. also my alt was checked a few weeks ago and they said it was charging 14. ? volts... put the boat back in the water sat and ran it a few hours. itts only charging about 12 to 13 volts on the gauge??????? is that enough
