[QUOTE="OutKast, post: 11924270, member: 42482"] The 2ohm speakers are the problem. Unless these kappas are like the ones I have been looking at buying that have a 2 ohm coil and 2 ohm wire impedence for a total 4ohm load. The amp will shut down once it becomes unstable at higher power levels with the ohm mismatch. The amp always must see an equal or higher impedence on the output than what it is rated. The speaker wire will be fine for the head units amp, since it is only rated at 53x4. There are a couple things you can do. Adding a 4 channel amp is one as long as it can handle the 2 ohm load. The other thing you can do, if you don't care about losing balance control, is to wire the left and right speakers in series behind the head unit. Resistance adds in series. Usually, or at least this use to be the case, the head unit manual will tell you you whether to use front or rear channels to accomplish this. I remember this usually being the front. I assume you have the connection adapter to connect to the factory connectors behind the head unit, if so this would be quite simple. This also assumes all four speakers are 2 ohm loads. If you want more clarification, I can probably add more from home tonight. [/QUOTE]
