    Lighten up, Francis. I started to post and couldn't finish until after you had added yours, so I didn't know about your info.

    • I think they came with 8 ga, so I would probably go to 6 ga. Yeah, it can be a PITA but it avoids problems.

      • jim you don't think i'll have issues with the 70 amp alternator do you? i'm not the guy that goes around blasting his stereo all day, but i would like to feel confident that i can listen to it at reasonable to loud volumes a couple times a year on houseboat trips and such without ruining my alternator, or hanging out and listening, starting, cruising, listening, etc.

        the larger 1000W amp is supposed to be super efficient, class G/H

          "it will be 1000W RMS on one amp ([email protected] and [email protected]) and ~400W RMS ([email protected]) on the 2nd. i'll never see that kind of output though. the smaller amp is a class AB and the larger one is a Class G/H amp with regulated power supplies and fans."

          If I hear your stereo up here, I will publicly post it here.

          Measure the voltage drop at the battery when you start the motor and turn all of the accessories on. If it drops more than a few volts, adding current draw will only make it worse. At higher RPM, it does produce more voltage and current but you need to deal with the draw at idle in order to not cause it to drop too low.

          What is the total of the fuse values on the amps?

          • how about if u are using a battery isolator do the batteries still need me be the same then or is it ok to use different ones?

            • the larger G/H has (4) 30 amp and the smaller AB amp has (1) 30 or 40 amp, i'd have to look again, it's not on their specs.

                  So, at 1/2 of worst case current draw, they could draw 50A-70A by themselves. If you're running at idle, your fuel pump, ECM, ignition system, lights and any other accessories could be drawing 25A-40A. The math doesn't make it look good for a 70A alternator. The batteries will fill in as a reserve tank but once they need to be recharged, it adds to the load.

                    I wondered what the pink reflection was when I looked at the sky.

                      If they're not in the same condition, one will always be an additional load.

                      • i was able to read the charging lead cable to the battery and it's 2 ga, so i'm covered. yay!

                        now i'm crossing my fingers my alternator can keep up. guess we'll know soon enough.

                          If you're referring to the one that goes from the battery to the starter, that's not it. You want to look at the one from the alternator to the starter.

                            I have the same question.

                            From what I read earlier in the thread, if there is an isolator in place, then you are covered... if not, the batteries need to be like kind.

                            I will be using an Optima D34M in conjunction with my stock battery... hopefully I am OK. If not, I guess I will be getting a second Optima to replace my 1 year new stock battery!

                            • sodar, jimn will probably chime in, but i've always been told they need to be the same. i think ultimately it depends on what type of isolator or combiner you choose along with how you intend to charge them off the water.

                                oh, then i misunderstood. i'll have to look. that's not difficult to change is it? maybe a back breaker, but is there something special about the connections or something?
