  1. Dont know if this really helps you but maybe think about the programming you like or plan to watch or if you prefer HD channels over standard and see which companies offer the best options for what you like.

    My only concern is a fast internet connection bc I rarely watch live tv anyways. I am always streaming nextflix and typically download the shows I like online and stream them through my tv.

  2. Heres one major thing i noticed with amps and their current draw.

    I have owned a decent amount of car amps over the past 2 years i have really been into car audio and i have learned that there are amps that are regulated and not regulated. There is a big difference between the two types of amps. Basically an amp that is regulated will put out very close to its rated power at a wide range of voltages where an un regulated amp will change its wattage output greatly. Now with un regulated amps, if your voltage for example is very low, the amp will draw more power to keep up with putting out its rated wattage. If you understand ohms law you can easily see what i mean. Ohms law states that volts divided by amps is equal to your wattage. So basically with a regulated amp that puts out 1000w rms, if your voltage drops down your amperage will need to go up in order to keep the 1000w power level. It also works if you have high voltage it will not take as much amperage to get the amp to put out that 1k rms. The benefit to amps that are regulated is if you have poor electrical in your car and suffer from voltage drop your amp will put out very close to its factory rating in wattage. The down side with regulated amps is that if your voltage drop is very low you will be drawing massive amounts of current through your vehicles electrical and cause a huge strain on your battery and alternator for it to handle that excess load. Another down side that i have noticed with several highly regulated amps i have owned and used is that when the voltage off your battery falls down, the amp gets really hot because it is working its butt off to try and support itself.

    Now for unregulated amps you can have different voltages and it will change the output of the amp a pretty good amount. With an un regulated amp it will really only care about voltage as opposed to amperage. With unregulated amps, if your voltage is low, your amps output power will also be low. If your voltage is high, your output power will also be high. These amps tend to draw the same amount of current on a wide area of voltages which is good and bad. The good with an amp like this is that you dont have to worry as much about drawing a ton of current through your system to support the power output you want. Another good thing is if your voltage is pretty high on your cars electrical, you can squeeze out a decent amount of extra power out of that amp. The bad thing with this is that if your electrical is low on voltage you will lose a considerable amount of power output from the amps.

    So basically current draw is mostly on how regulated the amp is. The impedance load and efficiency do play a role in it as well but if you were to take an amp that has the same efficiency, impedance load, impedance rise, wiring, class, etc but one amp was very regulated and the other amp was not really regulated you would see a difference in current draw from the two amps.

    Great explanation :good:

  3. If you have the money I would upgrade the alt but you should be fine with the stock alt and your planned setup. But if you plan to increase the wattage maybe it might be good to think about investing in a new alt. As for the capacitor I agree with everyone else and just go with batteries, kinetik and xs power are the popular choices.

    I am going with XS Power and there batteries provide the buyer with estimated power ranges. So if you system is 2500 - 3500 total watts they recommend a XS D3400.

    Kinetik batteries also has a power calculator that gives you suggestion on which of there batteries to purchase http://www.kinetikaudio.com/2009/powercalc.asp

  4. would a big 3 be beneficial with the cars battery already being low on voltage? or is it better just getting a brand new car battery?

    I would suggest charging it but if its an old battery and it low get a new one.

    There is some great stuff in this forum that explains how a cars electric system works and this might even help out

  5. ive never heard of a sonotube enclosure? wouldn't the cardboard rip apart form pressure or something or am i just missing something?

    Look for sixdogs1 on youtube. He is currently in the rebuild of his system he is going with custom made tubes. I am sure its been done before him but that was the most recent I have seen of anyone doing them.

    Hey OP maybe you could reach out to sixdogs on youtube and ask for some tips. He goes through his entire build process on at high level so that might give you so good tips. Good luck with the build if thats the route u go.

    thanks! i sure will. seems very interesting

    here is the video for Sixdogs1 - Operation Big Bang

  7. correct me if im wrong but....

    in the video with the focus, the reason he has a spot on the bass knob where he stops at is because he has a HUGE AMP on that one sub lol its been asked before, im pretty sure that why

    Ok well that would make since because i recall he was feeding the subs a crazy amount of power :lol: .

    So basically you should be able to set you HU then sent the gain on your amps and once you plug in your bass knob to your amp you should be able to turn it up full tilt without distortion. Which makes sense to me because I thought that bass knob only turned you subs from full power to low.

    So when using the DD1 it would probably be best to unplug or turn the bass knob all the way up when setting your amps gain, correct or it doesn't really matter?

  8. Isolator is not what you need in this application. Save that money and add a battery to the back. DO NOT FORGET to fuse the power cable coming off of the front battery and just before the back battery. A 3100 in the back isn't going to strain your alt too much, but you probably would be fine with a 3400.

    So you should put a fuse coming off of the front batt, then another fuse right before the batt bank and then another fuse between the batt bank to the amp?

    So 3 fuses total?

    Most people put a 300A fuse at either the front, back, or both sides but most people pick one or the other. I'll be fusing it closer to the rear battery.

    That's what I initially planned to do. I was putting a 300a fuse on the front batt then running that to the back. Then putting a 300a fuse from the back batt to the amp. So I will just stick with that.

  10. sooo if your bumping and it goes below 12v then need a another battery?

    If your bumping and it goes below 12 you need to look at your electrical system because something is missing and needs correction. Most amps tell you the recommended volts needed to achieve the rated watts. Amps would say something like at wired at 1ohm with 13.8v it produces 3,200 watts. Take that same amp at 1ohm but only feed it 12.6v will produce 1,530 watts. This is just an example but you are not getting your monies worth if you electrical cant keep up.

    Maybe the big 3 might help (not likely if you below 12v), new battery, buying additional batteries (xs power), new alt (dc power) or maybe a combination of things(xs power + dc power). It all depends on how much your trying to ask your car to do with stock electric and an aftermarket sound system.
