HELP!

[John858]

Hey yall, i was recently setting up my audio system. As i was connecting everything i decided to turn it on real quick n test everything out. Everything was working as it should be, and then i forgot to connect my subs so dumbass me connected them as the music was playing and boom, connecting the sub wires and it hits metal and a big spark. Now my bass amp is in protect, 4 channel amp only has grounding static coming out and my entire car wont turn on

(any reason to why this could be? any ideas help ; i checked the fuses on the car. Could my battery be fried) and before anyone ask yes i did have a fuse and the fuse popped which is why im so confused right now

Some cars have fuses built into the battery terminal. Check those. Is the car cranking over and not starting, or is it not cranking at all?

its crancking if the battery is charging, no charge its completely dead. But funny enough i took off the fuse and the car is starting like nothing. I wonder why this is, all my wiring i triple checked and everything seems to be fine what could it possibly be?

If you bypassed the fuse and the car started, then it may be a burned terminal fuse. Reason is that the ECU needs to "see" the battery's charge level to prevent overcharging and optimize fuel economy.
On older cars, an easy alternator test was to just remove the battery terminal while the car was on. If it remained running, alternator was still working. On new cars, if you remove the terminal, the car shuts off. Same happens if that terminal fuse burns out. Try checking the fuse with a multimeter.

terminal fuse? that would be the fuse on the power on the battery or where would i find it?

It would look something like this.

But now that you asked that question, when you said you removed the fuse, were you referring to the amplifier's wire fuse?

yes the amp fuse. i actually went to the battery shop n they said jt was fried, i just put a new one in and it works good now. im just confused that the battery fried instead of the fuse popping

That definitely is the first time I have heard of this happening. So is the sub amp still in protect?

Most probably smoked your amp. I don't think there's an amp on the market that's fused low enough to actually protect the amp from dead shorting the speaker leads to ground.

Anyway DO NOT attempt to hook up that amp to confirm it isn't powering up out of protect mode without using a very small fuse in line with the power (3-5A). The amp may be shorting the power and that would hurt your battery and possibly cause a fire if you continue to try to power it up and something really bad is wrong internally.
