    Default confused

    I will be building my first bigger system in about two months. I know what head unit and speakers that i want to use, but where i am confused is with the amps. I think i am going to use a 5 channel amp but I have seen the fuse on them range from 1 30amp to 3 35amp also seen them at 1 100amp. This is my issue I am not sure what i will need to upgrade in my truck to handle the extra power draw. I've read the alternator first then battery then capacitor. Then some where i heard that if i do the alternator that will not do anything and i should do the battery first. My truck has the 145 alternator and only the single stock battery. I have a 2011 chevy silverado z71 with tow package. So i guess my questions are at what point will i need to start upgrading stuff and what would be the best order if i need too.

    OK... Here is some info we need.

    What deck? (What are you going to use it for? Rock, rap, country, ect.)
    What kind of speakers? How many?
    Are you going to run tweeters and cross overs?
    What brand of amp? Wattage?
    How many subs? What kind? What ohm? How big?
    Are you using it ALL the time, or shot bursts?

    Let us know your plan then we can give you some more info..

    Also.. Is your truck a standard, extended, or crew cab? And what kind of motor in it?

    Ok here is what i am positive on right now. The Head unit Pioneer AVH-8400BH Speakers Massive Audio Rx6 componets 50-250 rms at 4ohms for the front and Rk6 coaxials 50-200 rms at 4ohms. As for the sub and amp not sure yet. I have looked at the kenwood xr-5s soundstream rub5.800 and ref5.1000 massive audio nx-5 (but read some bad things about this one over heating) and power acoustik gt 5-2500. also was looking at dual amp set-ups but figured that would be too much of a pain. As for the sub I was thinking nothing bigger then 600 watt rms again i looked at alot of different brands form alphasonik to kenwood to jl audio.

    How about the cab? Standard, extended, or crew? Be careful on your air space when you buy a subwoofer. Calculate your airspace o you will not get the proper preformance and life out of your subs.

    When you upgrade your system, the first thing I always do is buy a high output alternator and get it re spun by a specialst tighter so it puts out more amperage. Use a compasitor, and possibly deep cycle battery. It sounds like you can get away with that with what you are going to do right now. If you plan on going bigger, you can add another battery to the mix also. ZMake sure you have the proper amp cable so you don't starve the amp for power.

    My truck is a crew cab. I never even thought about air space. My concern is that one amp says it takes 3 35amp fuse and say the kenwood xr-5s that takes 2 30 amp fuse. I am pretty sure that most of my 145 amp alternator is going to be used by what is in the truck maybe leaving me like 20% at most so that leaves me with about 29 amps. Unless i am wrong it would already be more then what my alternator is rated for even if i get the kenwood xr-5s.

    That Kenwood is a Great Bullet proof amp.. But if you are going to a 600+Watt Sub you will need more. So I would look into 2 amps. If it was me JL Audio / Amps for True RMS power at 11-14.5 Volts. I would upgrade the power and ground wires. Get a Ohio Gen Alt and a Kenick Battery. As for your speakers You showed us a Wide range of power handleing BUT what is the RMS? I'm not upto date on Massive Audio. Have heard some good and some bad things about them.

    That is what the Rms is supposed to be for those speakers peak is 500 and 400. I've also looked at a ton of speakers every thing from German Maestro to Audiobahn ( a guy i work with loves them). That was just one i picked because they have such a wide range. I was also think of using a four channel amp and then getting a mono amp and a sub later only because i have a limited amount of funds. I orignaly was not going to change my head unit but decided that it would be better if i did that is going to cost about $750 by the time i get done with the wireing harness and everything. I am looking for good sound well balenced does not have to be competition just good sounding. I also like the kenwood excelon speakers. I know that it is kind of vague and i have been doing a lot of research. If i can build a nice system and not have to shell out $500 for a new alternator that would be great. I have read that you should change the alternator first then battery or cap. Then i called soundstream about one of their amps and the tech guy told me that that amp took a 100 amp in line fuse. I then commented that i would probley have to change my altermator and he said why that would not do anything that i would need a deep cell battery instead.

    My thoughts are that i would try to figure out what amp/amps first and then get speakers that will go good with what ever amp/amps i get. My orginal thought was about 4x100 @ 4ohms rms and 600 for the sub either at 2 or 4 ohms

    Well I do have to say When I build a system in my own Trucks I build it to Last and Sound Great at any Volume. My last system Lasted over 6 years with out even blowing a tweeter or Amp. And it was USED at times at FULL Volume in the Daytona Beach SUN for 8 hours a day. With the doors open you could hear it up to 75 yards away as clear as day. Not Bright Not Harch. You heard every Beat Highs,Mids and Lows. Yet I could still drive it around town and enjoy some 5.1 Audio inside. Speakers and Amps were JL Audio Headunit and prosecer (spelling) Were Kenwood.. I have heard 98% of the speakers on the market, I have sold about the same. I have seen the Best and heard the Best audio systems ever built.. (For those who remember Richard Clarks Grand Nat) Is there better then JL? Yes But not much and not in the price range.

    Your friend who likes Audiobahn... Tell him to listen to them not just look at the Flame amps and Subs.. Kenwood Higher end Have always been good. Some other speakers to look at for what you listen to Alpine Type R and Focals. The K2's you will be very happy with.

    Caps are a waste of money.. Stop going to Best Buy... Alt and Batt will be fine.. BUT if you were going with that Amp that draws 65-70 Amps. You will be fine (as long as the truck is running) with stock..

    Ok Enkeiavalanche This is more then likely what i will do. Head unit Pioneer AVH-8400BH Speakers Kenwood Excelon XR-S17P componets for the front and Kfc-x1730 for the rear Amp the Kenwood xr-5s 80x4 @ 4ohms and Subthump single downfire box with a XR-W10F Kenwood sub. The Amp takes 2 30 amp fuses. What are your thoughts.
