    I need some system help for my VW Bug

    Hello everybody!

    I am trying to set up a decent system for my '66 vw bug and I'd like to ask for your sugestions.

    The primary goal I have is for it to be completly stealth from the outside. The car still has the old am radio in the dash so I figure it can stay there.

    The head unit will be mounted in the glovebox and the front speakers will be in carpeted over kick panels forword of the doors. I also plan to build a concealing shelf over the rear luggage area to hide a sub box and perhaps mount some rear speakers to.


    Here's what I have to start with:


    Blaupunkt Casablanka Head unit

    Pair (set) of 6.5 inch Infinity referance components (for kick panels)


    I know that I want to amp the infinitys but I am pretty new to this. They have an RMS of 20-90 w. When chosing an amp, what RMS should I send toward these? Toward the higher end (75) or should I try to stay in the middle (45)?

    My initial thoughts are to get a 4 channel amp with 2 channels going to the front and the other 2 bridged into a 10" sub. What do you think?

    Any thoughts would be greatly appriciated.

    Personally, I think its better to run a separate amp for your subs. Look for a 2 channel amp with about 50-80 watts RMS output per channel for the speakers. What sub are you looking to get? Any ideas yet?

    Thanks for replying.

    I'm still not sure about a sub brand yet. I've had JL sugested to me quite a bit though.

    I also have a line on one of the boston acoustics 10" competition subs in a small box with the moving membrain. It would be pretty cheap, so I'm thinking about it.

    Are these a decent buy?

    I had thought about a separate smaller amp for the fronts. Any brand sugestions? My budget would be under $200

    Here are 2 good amps IMO that will fit in that budget:

    http://www.etronics.com/product.asp?stk_code=sourub3002
    Also, for subs, how much are you looking to spend? You should look into the Elemental Designs K series, and Adire Audio Shiva. Here are the sites:

    A friend of mine has some older soundstream stuff and it sounds great. I did not even know they were still in business.

    I have to look into the PIC2.240, I think it may work for me. I may have missed it, but what efeiciency does this amp have?

    I'm concerned about the power it will draw out of my battery. These old bugs don't have the best electrical sytems any more!

    Sub wise, The elemental designs K Series looks good. Thanks for the tip.

    I just want to be carefull not to break the bank. To think this all started out so innocently.

    I'm not sure how many amps the soundstream will use, you know the output of your alternator? I say the K series is your best bang for the buck 10" out there. You can find a good amp to push it for about 150-200 too. Let me know, I'll dig up some more amps for ya.

    Unfortunatly I've still got a 40 amp generator but I'll be upgrading to a 75 amp alternator in the near future. (maybe sooner than I thought!)

    Hence the power draw an amp will have has become one of my big concerns.

    Are you set on the 75 amp alt? Maybe you can bump it up to a 100 amp, that would probably work fine. But I think a 75 amp alt would work ok, considering the speaker amp is 200 watts, and whatever sub you get will probably be around 4-500 watts, so thats 6-700 watts total.

    75 amps is the highest I've been able to find so I'll have to cross my fingers. The good news is that The only other powered things on the car are the lights, wipers, and engine

    Well, go with the 75 alt, and if you put in everything and see that the alt is struggling, get it rewound to a higher output, it doesn't cost that much, I've heard from $ .75-1.50/ampere. So you rewind it to 100 amps it would only cost around 25 bucks.

    Cool, I didn't know that you could get them re-wound

    What is the best type of enclosure to use for these K series subs?

    For me spacewise, the smaller the better

    I'd say anywhere from .4-.8 cu. ft.

    I'm going to install the infinity's and head unit I have this weekend and hopefully decide on an amp by next weekend.

    Is this a decent amp?

    Thanks for your advise, I'll definatly have more questions when I get farther along.
