    Did you just add the big 3 or did you replace any stock wires?. . . . . And yea like above, what alt did you get? And have you tried putting the stock alt back in to see if the problem stays?

    I added all 0 gauge wires for the big 3. Quality power 175a H/O alt. that's the only brand that sell alternators for my car and if it comes down to it, I am going to install the stock alternator and see if the problem continues. I really don't want to though because the alternator is near the bottom of the engine and really hard to get to.

    Hey everyone, I got a sundown x18 powered by a hifonics zeus 1800 and crescendo components to the doors on 600w hifonics zeus. I was running this setup for a couple weeks with stock battery, stock 75a alternator, and no big 3 with no problems at all. With the stock setup, my volts were around 14.2v at idle and when I turn my system up it usually drops from around 13.1-11v and the stock alternator kept up pretty well. I decided to get a new Kinetik 1800w battery, a 175a alternator, and I did the big 3. When I did all of this, my system got worse. My volts were running at around 13.4-13.7 and when I did something as little as rolling up my windows, it drained he volts all the way down to around 12.5. I can't even turn my sub up nearly as much as I could with the stock alternator or it will drain to as low as 9v. I put the stock battery in the engine again because I'm planning on running my Kinetik in the back. As of right now, my volts are still dropping like crazy and now when the bass hits too hard, all of my lights in my car dim including the amp and my amps shut off for 10 seconds then my whole system reboots. I am clueless to what it is and I am getting so frustrated. If anyone has an idea of what could be causing this, I would really like to hear. Thanks in advance.

    Ok I think I found the problem. I bought these two battery terminals and It has 3 inputs for wire on each side and when you put the wire in, it is supposed to compress the wire and make it a better connection. It doesn't fit on the battery snug enough and the wires are so loose I could pull them out of where it is supposed to compress the wires. I'm going to take the battery terminals off tomorrow and just hook the wire up straight to the battery. Right now, I re-tightened the terminals and I can play my music loud without it cutting out and the alternator is keeping up a little better but if I turn the bass up all the way, my volts drop down to as low as 10v. When I turn the music off, the volts shoot back up to 13.8v. Before I even installed the alt, batt, and big 3, my volts were running around 14.3 and it would only drop to around 12-11 volts when there was a ton of bass. Hopefully when I hook the wires up without the fancy 3 way terminals, I will be getting the full power.

    maybe your serpentine belt is to big? mine was doing something similar and I went and got a 1 inch smaller belt and it took right off.. the old belt must have been slipping a little or something but not noticeable to the eye

    i actually think that might be the problem. I installed a new Serpentine belt with the rest of the things yesterday. I just double checked all the connections and they seem to be tight. The alternator is actually keeping up with everything now but when I turned the music up, it seemed like all of the electrical cut off and reset while the engine is still running. It also cut off for a second when I put it in drive and started to go. I think it might be the serpentine belt slipping when I give the engine power.

    When you have the time, you could go back to stock and make sure everything is working correctly. Then just change one thing at a time until the problem does, or doesn't show itself. Process of elimination should work here since you didn't do a ton of stuff at once.

    yeah it's gonna be a pain to take the alternator back off though. It is in a horrible spot near the bottom of the engine. But if that's what it comes down to, I might have to put the stock back on

    Provided you double checked the wiring and solid grounding, where did the alt come from?

    I'm gonna double check the grounds tomorrow. The alternator is a quality power alternator. That was the only brand that sold alternators for an isuzu trooper. Also, there was a wire connecting from the alternator to the main fuse box. I was told I didn't need that so I took it out and just had a wire going from the battery to alternator. Would that effect it at all?

    Hi everyone, i was upgrading my cars electrical today (big 3, new 175a HO alt, Kinetik 1800w batt) and when I was done installing it and I turned over my car, I was running 13.8v. When I started playing some music, it sounded like it was quieter than when I had stock electrical. All the lights in my car were dimming and the volts were dropping as low as 10.5v. The alternator was charging real slow and having a lot or trouble keeping up. What could the problem be?? I am absolutely clueless on what it is so if anyone has a good suggestion, I would love to hear it. Thanks in advance

    Here's a little update. The box is almost done, just touching up a few things. Il post a pic soon. I'm hopefully ordering the next set of things soon which are: 175a high output alternator, a xs power battery, a 500w hifonics zeus amp for door speakers, rockford fosgate front door speakers, and some wire for the big 3. I'm going to install it when it gets a little warmer out.

    Eesh, gotta say when I first saw the surround roll on the X series I was a little put off, thought it looked goofy.  And now every time I see one I want to fill a Suburban with them.

     

    I love that basket too, I'm not sure I could decide to mount ass out or conventional.

    yeah I love the sub! I can't wait to here how it sounds.

    You built it different then what the cut sheet said lol

    yeah I know lol I already cut the wood to 35 inches for the x15 box so I had to figure out how to get the inside dimensions the same with the wood I had.
