You need a minimum of 2 gauge wire for that amp, depending on length of your wire, maybe even 1/0 gauge. Your other issue is that vehicle only has a 90A alternator. That would provide about 1000W of music power. Anything more and you will be running off the stock battery power. Since you have a stock battery that is not designed for audio, it will only help for a split second. Then the voltage will drop way below safe levels (10v or below) and at that point, either the amp will go into protect mode and shut down, or you will start blowing fuses.
That is the bad news. Here is the good news. You can replace your stock under hood battery with a better battery and add a second matching battery in the trunk. The combination will allow you to run off the battery power without running the voltage down into that unsafe level as before.
Recommendation from me (I work for Kinetik) is to replace the stock battery with an HC1400 and place another HC1400 in the rear near your amps. You will need to wire the batteries together using 1/0 gauge wire and use a 300A inline fuse on both ends of that POS+ wire. You should also check the grounding spot you chose for grounding the amp in the rear. You should ground the amp to the back battery, then ground the back battery to the chassis with a 1/0 gauge run. Make sure it is a good solid piece of chassis. Under the hood, upgrade your wire that goes from the stock battery to the chassis with a 1/0 gauge wire as well. Also, make sure that the wire that connects your engine block to the chassis is upgraded to 1/0 gauge as well.
In the future, you may want to consider an alternator upgrade, however it will be expensive and you will have limited options with that type of car. Most small import cars are hard to find a larger alt to replace your stock one.
