i need help finding a way to get the wires from my battery into the cabin on my 855. i have it in the shop right now and can't find a hole to go with. please help and pics would be amazing but a good description would work.

thanks

its been addressed before, but for simplicity, i use the location where hte cltuch would have gone through.

look next to your brake pedal where it goes into the fire wall, you will see a little cut out in the factory dampening, or it may not be there and you just see a little piece of the firewall, take a nice unibit and go through there, done

well i drilled a hole in the sport where my clutch will go someday, it worked well enough. i ran everything loose and tested it out and it all worked sweet. then i took it appart and ran all the wires clean and under The carpets, came out real well. then i hooked it back up exactly the same nad now i get nothing from my sub. i was pissed. i think i somehow managed to kill my amp.

question: if i take a test light and hook it to ground and the other end to the wires going to the sub should i get a light from at least one wire?

i currently get none, i do get power into the amp and the signal seems to come in.

anything else i should test out?

ok so tell me what i did now!!

i layed out all the wiring and made sure everything worked and it did. i then unhooked everything and layed in the wires and hooked it back up and nothing worked. then the strange thing happened: my little clock thing and temp are now reading military time and centagrade. i did nothing to these that i know of, so how did i manage to have them change and how do i change them back?

i am fully stumped now!

thanks for the help

i swear it worked when everything run loose.

yeah i get power into the amp with a test light. the light on the amp comes on with the key but i get nothing at the sub.

is there a way i can use the test light to see if i am getting signal through the rca cables to the amp and also test the wires going into the amp?

thanks for the help

first things first: you have these right:

1. rubber or plastic grommit on where ou made the drill out so its not cutting hte power cable and causing short

2. a fuse on the main power cable?

3. solid ground connection on the amp

4. clean connections on the amp (look for loose conenctions, and stray wire strands that maybe touching one another)

now, when you say it lights up red, on some amps, red LED means its going into protection, green LED means normal operation, can you verify this this is?

if the amp is going into protection, you have these possiblities:

1. the positive and negative wires are touching each other, cuasing a short

2. bad amp

3. sub impedance too low

now if its not going into protect, and you are just not getting sound, and you know the amp is one, you have these possiblities:

1. bad or loose rca cables coming form the headunit

2. bad or loose sepakre wires from the amp the sub

3. completely dead sub

4. dead amp

5. bad headunit output

start a process of elimination.

first take a house hold 9 volt battery, take the positive and negative wire off the amp, and put the wires to this battery, if the sub makes a clicking sound and moves a little (if you ave a bigger battery), then the sub and the sepaker wires are fine. reconnect the speaker wires to the amp.

next check hte rcas, worse comes to worse, run a new rca just inside the car from the hu to the amp for testing purpsoes, if this fixes it, its a bad rca.

if the speaker wires are good and the rcas thing doesnt make a diffrernece, try to plug the rca into a different set of rca outputs on the headunit, and see if you get any sound, if this fixes, then you have either a muted or broken rca output on the headunit, if this doesnt, then youa re probably looking at a bad amp of some sort or not set correctly.

good luck

thanks for all the help. i went back and traced and retraced everything. it works now. turns out the ground was suspect. it was grounding but not very well. at one point it was good then when things got shifted it went bad. i knew it was going to be something like this that makes me bang my head on the wall. i moved the ground and it made the test light glow real nice and now my stereo has some base. next is going to be replacing the stock speakers with somehting nicer.

i still do not know how i changed the time and temp settings or how to change them back. any ideas?

thanks
