    Just won a 12" Kicker solo baric on auction, how much power should I put behind it? Do you think that you will be able to feel it outside the blazer? Cant wait till it comes! PS. how do you bridge 2 channels into 1? It comes with a 300 watt 2 channel amp. I was told to take the pos fron 1 and the neg from another and it would give me a full mono 300 watts.. Thanks for your help!

    The way you said is pretty much how it's wired up on the amp for bridged output on most amps. Keep in mind that the L7's are dual voice coil speakers and that can make a difference on how you need to wire the amp. Check with the seller to find out if it has 4 ohm or 2ohm coils. If the amp isn't stable at low imp. loads you could blow the amp. If you have 4ohm coils and the amp is 2ohm stable bridged then wire them parallel. If the amp can't handle 2 ohms in bridge mode wire the coils seperately to each channel.

    If they are 2 ohm coils and the amp is 1ohm stable bridged (highly doubtfull) then run them parallel if it can't handle a 1ohm load then check to see if it's stable at 2ohm stereo (quite likely) and run 1 coil per channel. If the amp needs a 4ohm load bridged and can't handle 2ohm stereo either then run the coils in series with the amp bridged.

    No matter what configuration you use be sure to ALWAYS USE BOTH COILS. NEVER USE ONLY ONE VOICE COIL!!!.

    Those speakers will hit plenty hard with 300watts and can take plenty more power so you shouldn't have to worry about blowing them as long as they are wired properly and installed in the correct sized enclosure.

    With only 1 12" you will surely be able to hear it outside but it won't be felt much on the outside of the vehicle.

    Good luck with the speaker... As long as it's in good condition you should be pretty happy with it.
