    the Kenny subs it is then!

    will i need a power cap to power two subs, or should it be ok?

    also, the way ive been told to bridge it is - (is this right?)
    sub1 - channels 1 and 3
    sub2 - channels 2 and 4

    lastly, ive mentioned i want Pioneer TSA-6910 330watt 3-way 6x9s, did Kenny do good speakers? i want to try and get them a bit more powerful as well, like 400watts or so, is this possible?

    cheerz!

    wot u wanna do is positive of channel one, negative of channel two for one sub.

    positive of channel three negatrive of channel four for the other one.

    and if ur runnin ur 6x9's off of ur hu, 330watts is plently.

    and them 6x9's uv got r really good for treble.


    kenwood tend to do 7x10's,

    theyre also pretty good.

    up to u matey but run 6x9s off hu rear channels, get a decent pair of tweeters for the front channels of the hu, run sub of a bridged amp and ur car will be a pounding with sounds.

    I'd go for the cap just incase.

    Depends on the amp, it should be marked on the speaker connectors, but the way you've described is the usual way of doing it but best to make sure first.

    Don't have 6x9's at all, get some componants (Like Kenwoods) up front and maybe a pair of small Kenwood 2 ways in the parcle shelf supports for some rear fill (Will sound loads better this way).

    if i use the + off c1, and the - off c2, cuold i use the - off c1 and the + off c2 for the second sub, therefore leaving c's 3 and 4 available even powerful 6x9s?

    also, on a different note, if i do put the 6x9s throught the hu, i want to fit a cut off switch, so i can turn the amp (and subs) off and on when i like with all speakers remaing on, does that make sence? , would that work?

    cheerz!

    no mate that wouldent work you can put the +c1 and -c2 then if ur amp will take it piggyback ur +off 1 sub to the + on the second sub and the same with ur- then it is wired parallel that should work or just wire them up normal =+1-1 =1sub 1 channel +2-2 =2nd sub channel2 leavin 3+4 4 6x9s

    Yeah, quite simple, just fit a switch to the remote power lead from your headunit to the amp.

    But by wiring them in parallel you'll be halving the output to each sub which means they won't be nowhere near as loud as they should (or could) be, It'll also drop the impedence down to 2 ohms and I expect the subs you'll be getting are designed for 4 ohms impedence (House stereo speakers are 8ohm which is why they sound so crap in a car).

    Wire the subs to the amp as shown and the 6x9's from the headunit, most modern headunits have a high enough output nowadays anyway.
