I have a Kicker CX300.1 connected to 2 12" kicker subwoofer and when i turn on the radio the amp keeps on at the red light, but once i turn on the ignition the green light keeps blinking and the red light keeps still lit. I do not know what it could be. Could someone help me. I do not know what could be wrong.

parallel wiring. hook all 4 positives together and run to the positive output from the amp, hook all 4 negatives together and run to the negative output from the amp.

hope this helps,

SOURCE: bridge subwoofers

Without looking up the individual specs of your speaker and amp, I'll offer a few basics when it comes to bridging an amp.
Most important...find out what impedance (ohm) that your amp can handle bridged!! If you go below this rating, you will run the risk and most likely eventually overheat and short circuit the amp. You must also know the impedance of your sub (which can come in a variety) to be able to match them. Depending on this impedance match-up, it may be less beneficial to bridge the speaker to this amp. For example if there is an impedance mismatch you'll either get less power from the amp or short circuit the amp. If you know these I can help you come up with the best solution.
If you know bridging is the best option, then you'll have to know which terminals on the amp to use in order to bridge. This is how it normally works. On a 2 channel amp...you would normally take the positive from one channel to the positive on the speaker, and the negative from the OTHER channel to the negative on the speaker...and this is how you bridge the amp. The other two channels would remain UNCONNECTED. BUT!!! you have to make sure you use the correct 2 channels...it varies from manufacturer. But take heed not overload the amp...and not to overpower the sub. There are a few different ways that you can configure the subs if you find it beneficial to bridge your amp, these would take long to explain and would depend on the impedance of your subs and specs of your amp...these wiring configurations is how you match the impedance of the speakers input to the amps output (and is very important to do correctly) Look up "parallel and series" wiring configurations. Let me know if this helps, or if you need further help. Find out the impedance of your subs and the specs of your amp and i'll be able to assist you more. Hope this helps.

SOURCE: how to wire my kicker solar baric

All depends on your amp. Is it 1 ohm stable or not?
Parralell:
positive (pos) on voice coil 1 (vc1) to Pos on vc2 and negative (neg) on vc1 to neg on vc2. Then speaker wire from amp to one vc only = 1ohm load.
Series:
Pos from amp to Pos on vc1. Neg of vc1 to Pos of vc2. Neg of vc2 to amp = 4 ohm load.

it sounds like you have some wires crossed or a bad ground
Hope this helps

SOURCE: i turned my 15" L7 kicker and smoke started to come out the box

As stated before, knowing the impedance of your subwoofer would really help the situation. Either way the link I have provided is to your subwoofers manual (Incase you dont have it)

But since you have said it has smoked, if it still works I recommend turning the bass boost down (Bass boost causes alot of heat within the subwoofers voice coil and even within the amp itself and should never be maxed out.)

Here is a link to your manual for the subwoofer.

So as a solution to your issue, keep your bass boost turned down. You should almost never need it if you have tuned your amp correctly (You have a very serious subwoofer there)

Consider yourself lucky if your subwoofer is still working without issues.
