Help Installing a 2/3/4 channel amp

[husker822]

I have an Alpine Flex 4 2/3/4 channel amp and I was wondering if it was possible to hook 2 4X6 Kicked KS in the dash on 2 channels and a Kicker 15" comp on the remaining 2 channels. Is it possible to bridge two channels into one? The amp says brigged on channel 3 and 4.

As long as your sub is wired to a 4 ohm load on the amp (either a single 4 ohm vc or a dual 2 ohm vc), you will be able to bridge channels 3 and 4 to the sub. From what I remember, the Alpine flex amps were not all that powerful (around 40-50 watts per channel). You might not be getting enough power to the sub by doing this...but as long as your not a bass nazi, it should give you "decent" output.

Put how would I wire it? Twist the + with + and the - with the other - and connect the wires to the sub?

No, you'll use the + from one channel and the - from the other channel. Look under or above the speaker terminals on the amp and it should tell you which ones to use when bridged. Remember...if you sub will not be a 4 ohm load on the amp and you bridge it...you might fry your amp eventually.

I believe my sub is a 15" kicker 8 ohm, would things run smoothly if i bridged the 2nd and 3rd channel?
