I wired everthing up and put the hot wirer back on and the amp wont come on fuze r all ok

Ck. & see if you have power at starter with a test light have someone turn key should have power to 1 of the small wirers as well as the bigger bat. wire. Possibly a bad solenoid which is on starter where the wirers go.

the amp has power, ground and emote turn on? is the amplifier lighting up? is it going into protection?check the wiring to the amp before you suspect a bad sub and amp

Is the yellow wire hot?

you don,t want to just put a toggle swich in becuse if you are grounding it out you could catch it on fire so check your wires first

Having gone over a month without a response, I assume my suggested reset solved the problem.

The battery itself is toasted.
Replace it.

what wires? plug wires?
battery wirers?

the stereo fuse is under the hood in fuse box and uses a five or ten amp fuse no fifteens will blow it right up

2x12 in sub each duel voice coil can iether wire to 1 or 4 ohms. im guessing you have everything wired up in series (1 ohm) and aer probably burning out the amp.
