    When it comes to audio devices like these transducers, I'm a little lost.
    I have the TT25-16
    Could someone explain to me what I need to power 3 of these and how to wire them please?
    I was to put one on the bottom of the pedals and 2 in the seat.

    What kind of amp do i need?
    What kind of sound card do i need?

    Amps, ohms, impedance, frequency response etc all baffles me.

    Thanks
    That link helps a little. It's still pretty confusing. I'll read it all the way through later.

    I'm wondering if this amp would work: http://www.ebay.co.uk/itm/Mini-Hifi...336894?hash=item5415ffc67e:g:rZAAAOSwD0lUho9q

    It's 4 channel (giving me the option to have another unit added at some stage)
    4 x 40W output power
    4 Ohm
    It's cheap
    It's really small and light

    But as the transducers are 16 ohm does that mean that I will actually be pushing a lot more power through the transducers than I need or do I need more power? The impedance is the bit that confuses me.

    When the speakers have higher impedance compared to an amp, the speakers will draw less power from the amp. In this case 10W I would think. Those pucks are 1 Watt RMS so you'll be just fine. In reality those pucks dont provide much vibration. You'll have to mount them ask close to your body as possible.

    Yes I know they're not as good as a full set of butt kickers but they're small and cheap so they'll suit my rig to start with. Each puck is 15W RMS so does that mean i need 45W at 16ohm or 90W at 8ohm and 180W at 16ohm to power them????

    Hi, you need 15W RMS at 4 Ohm to power them. So in your case you'll get 10W to them, which will probably be fine.

    Actually, you can use any wattage amp you want. It's just if you turn the volume up too much on a more powerful amp and output too much over 15w RMS for too long, it will probably burn out the transducers coils at some point. But with 16ohm transducers you can probably output up to 20w RMS okay unless the amp is rated at 16ohm too, then it should stay closer to 15w. If the transducers are cheep anyway then the best way to find out what they can take with whatever amp you want to use is to try one and see what it can take before it fries.

    It is true for their resistance.

    Their impedance folows the same rule but also depends on the frequency that you drive them with.

    Imho you are way over thinking this. Bottom line though is if you run 4ohm speakers with an 8ohm rated amp for example, you risk blowing out the amp because it takes more current to drive @ 4ohms than it does @ 8ohms (consider that 0 ohms for example would be a direct short to the amp). And if you put more watts to the transducer than its rated for (to much volume), then you risk blowing out the transducer.

    I would be over thinking it if I actually understood it. Now that I understand it a bit better I can make a decision on which amp to get, and also which way to wire the transducers.

    You are over thinking trying to understand it then. :p But if you're worried about blowing out an 8ohm amp with 4ohm transducers then wire two in series and you'll have the equivalent of an 8ohm transducer. But it will need twice the wattage from the amp to drive it fully (15w + 15w = 30w).

    That's very useful info I've gathered from this. Thanks for your advice. I think I'll buy another transducer so I have a set of 4 to make it easier to work with and give an extra bit of feedback. I'm on the hunt now for an amp to suit the system.
