at least 14 ga for speakers 8 ga for amp...be SURE to use an inline fuse between battery and amp

yes, there is an amp turn-on wire from the head unit (black with a red stripe). You will need to add a power wire and fuse from the fuse box to run the amp. You can use the speaker outputs as inputs to the amp, depending on what you are trying to do. Please let me know if you need more help, and identify the amp model as well as the speakers you will connect.

Here is the manual for it:

The fuse size is 2 x 30 Amp fuses.

push it in a little bit to see if its blown

replace the built in amp

the sub is probably drawing to much, check the impedence of the sub against the amp, could be causing the amp to over-heat (thermal-cutout, thats why it it will start again after a few minutes after its cooled down), you may need to get a bigger amp to run it.

Many vehicles have the fuse block under the hood (for fire protection) otherwise your owners manual should be very helpful.

Might not be eathed properly. Check the earth on the battery as well. Theres more juice goin through there now so it might need a bigger earth or ground.
