You pull up the carpet where that velcro spot is, if you look there is a rubber grommet right next to the velcro that runs into the engine bay through the firewall, this is where you should run the wire. I have a 2k1 EX Coupe and that is exactly where my power wire ran.
Do i connect the + power line directly to the car battery ?
i got a 300 watt amp and alpine type S sub
do i need any capacitor in order to run the sub safely?

From what i understand... you need to put a fuse between the battery and that power wire. Someone else please verify this.... im gonna be doing the same thing before the end of the week. :-p
Yes, you need a fuse right off the battery. Genereally within 18" of the battery. Generally this fuse should be equal to or a little above the total of all the amps in the system. Your Sony has two 30 amp fuses. Any fuse from 60 to 100 amps would work fine for you. If you get that kit it will have a fuse holder and fuse included just for this purpose (ATC in-line fuse holder).
The purpose of this is to protect you if anything goes wrong. Thats why the closer the the battery the better (thats the within 18" part). Does it happen often if ever, no. I personally have never had a problem. But if you did it could save your car from an exploding battery, wiring meltdown, and the car catching on fire.
I did see it happen w/ my brother once. He put in his first stereo and routed in the power wire. Fired it all up and the system was just a bumpin (four JL 10" on a MTX amp). So then he goes for a cruise and go show it off. He pulls in the parkin lot and presses the e-brake pedal (truck was standard and needed to be running cause the amp used so much power). Well f course he wasn't so careful in the wire placement up under the dash. That brake pedal cut the wire casing and grounded it out quicker than he knew what happened. Nice big shower of sparks, it was scary. Thank god the fuse blew right away, shut the whole system down quick, and saved us. He felt like an ass and we were done for the night. Try finding a 60amp fuse 10PM at night in a small town.
Good luck.
I still say get that package. Its gots everything to do it right...... might even have directions.
coat hanger or something. I just took a coat hanger and bent it and then shoved it through from the inside of the car, taped the wire around the coat hanger and pulled it back through.
i did that too. Worked out just fine. I got my amp all wired up, but have one problem; there's no sound. The amp power light is on, so the power aspect is good, but there is absolutely no sound coming from the subs. I fooled around with all the switched on the back, which did nothing, so it has to be a connection somewhere. Any hints on the most likely suspects? I really don't want to have to unbolt my sub box and take it apart....so I hope it isn't in there. Thanks.
Do you have another speaker you can plug in to eliminate the sub and wiring inside? Also make sure your RCA connections are good and that the RCA cable works. Its pretty simple really, there is only 1 in and 1 out, so do some process of elimination. Try different cables, different speakers, you could try also a different source if you have a portable cd player with line-out outputs and just keep the volume really low to see if its your headunit. Just eliminate everything till you find the culprit.
i have a high to low converter hooked up to wires spliced off the rear speakers, so that might be it. I'm not sure if the + and - are hooked up correctly on the right one; would that affect the sound like this? I'll see if I can get some speakers to test, thats a good idea.
