ok help me troubleshoot my system

As thecybe noted, its quite possible that happened.

Seeing as a brutus has fuses on the unit itself, those would be the fuses that would blow if the amplifier actually "sees" whatever amperage that is. (ie if the amp pulls 100 amps and you have 50 amps worth of fuse, the fuse will blow)

Basically we're telling you that the problem with your fuse blowing HAD TO have happened somewhere between the blown fuse and the unblown fuse. Here, the blown fuse was under the hood, and the unblown fuse is in the amplifier.

So, I am going to conclude that the problem is definitely somewhere on your power wire.

yea the power wire goes from the inside cabin through the door frame into the engine compartment so the door closes on the power wire , i know its bad but thats the only way i could get it through

The good 'ol power wire through the door technique? You have to make the sacrifice of drilling a hole if it doesn't fit in any existing hole. More about safety than convenience.

With regards to no sound: try playing a sine wave with the HU-output RCAs disconnected. See if you get any voltage on those (make sure you're in AC[~] mode on the dmm).

ok yea i found out the door totally fuxored my power wire, i just taped the shit out of it, got a new fuse, and it turns on fine

still no output from the subwoofer though, and i still have no multimeter and the only home audio player that has rca's is in my parents room and they totally anal about me messin with there stuff

hmmm crap man i cant figure out whats wrong.... this sux //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

I suggest you buy a cheap 5 to 10 dollar meter...with most electrical troubleshooting, it's a necessity.

Instead of a home receiver, you could try grabbing an RCA to 1/8" (minijack) adapter:



...and plug some headphones into it. I think the volume out the headphones will extremely low, if audible at all, ... so in that case you could grab the adapter with a male minijack:

...and if you have some portable device (cd-player, laptop/computer, headphone-amp) with a line in that amps up the signal, that would suffice.

But buying a DMM would be the most practical method.

umm ok can you explain that again? i dont quite understand ... so i take a portable cd player, plug in that thingy in the headfone outlet and then plug in the rca's into the adapter, and the cd player will output through the rcas?

You would plug the headphones into a line-out, not a line-in. Well, you wouldn't really plug headphones into a line-out either per se, you need something that will amp up the line-out. Some portable CD players have line-ins, some don't. Now that I'm thinking about it, I'm confusing line-in with line-out (when it comes to portable CD players).

For example, using the 2nd pic that was posted: the RCAs from the HU would go the right side of that adapter, you'd plug the other side (the protruding/male mini-jack connector) into the line-in port of a computer's sound card.

But seriously, it's not worth it & you can just scrap all that I've said...and just buy a DMM.

The VERY first thing I would do with you is slap you upside the head. Then I would sit you down... away from your car. Then I would completely rip out your entire install and REWIRE it the correct and UN-GHETTO way.

You're crazy dude, you wonder why stuff in your car doesn't work? All of car audio is install dependent. You can have the very best equipment in the world sound like garbage if you haven't a clue or the drive to install it correctly.
