Is it ok to wire ahead of time?

Ok im really bored this weekend and i was thinking that i would run my rcas (connect them to the back of the deck even), and back to the trunk...wire my power wire allthe way to the battery to the trunk, and run my new speaker wire to the doors. that way, when i get my adapter from servo and my amp i can just plug them both in and cut the wires to the harness from the front stock speakers and plug them off...is it ok to do all that? i cant forsee why not, but i figured id ask...cause im pretty impatient and when i get all my crap im not going to want to take all day to mess with the s***.
 
The biggest thing is DO NOT PUT YOUR FUSES IN. Having a loose power wire with juice going to it floating around is a bad bad thing. You might want to cap off your RCA's as well as I've gotten a bit of scratchy nasty possibly damaging noise from loose rca ends touching grounds and eachother before. That aside, everything else should be fine. Preferable infact. I wired alot of my stuff in a similar manner. Get everythign setup first all of the tricky stuff out of the way so that when the time comes all you have to do is plug everything in and fireit up. Just make sure that you take your time and do it right. A shortcut here or there to save a couple of minutes won't sit easy with you for the rest of the life of your car. Anyway you might be caught off-guard by how long it can take, keep that in mind. You might wanna go in steps. Let us know if you need help running stuff, of course everything's pretty well-documented inhere already.

One thing I personally suggest (And I doubt many others will) is under-seat amps. Just my personal preferance, but I like having the extra room in the back for gear and such, and never have any intent of building an amprack and a nice showy setup. I found there's LOTS of room under the seats in my p5 for amps, and it makes all of your wires shorter to boot. Plus it's kinda cool to pull your seats out, and have a big open area inside to crawl around in, which I might reccomend anyway.
 
I agree with poseur here...it's not a problem to wire up so long as you're careful...just make sure you plan everything out well enough...It's that whole measure twice cut once rule.

Thats a good point. you have to make sure you have enough wire and things. you dont want to be ready to get everything going and find out that the stuff dont work cause teh wires are to short.

like said before tape off the RCA's and dont hook up the power wire (atleast teh fuse)
 
thanks for the advice...some day i plan to have the amps in some nifty thing with my sub, not sure what yet (had an idea like protege5gurly, but not 100% sure)...yea i didnt plan on putting in the fuses, and i planned on taping off the end of EVERY wire. my question is, when it comes time to install the front door speakers to connect them to the amp, can i just cut the factory speakers and tape them off? that way if i ever go back to stock theyre just sitting there? or do i have to run the speaker wires from the doors to the front, then to the back? thats the only problem i forsee, is running the front door speakers into the back. everything else ive done several times before on my previous cars, except putting the power wire through the firewall...i have big stupid hands, i may struggle a little bit with that. i just opened my knukonceptz wiring kit today, damn its pretty nice looking...the blue power wire should match nice, though i may eventually replace the aquamarine fuse holder.
 
Mathew, that is exactly what I did with my Yukon. As a matter of fact, I still haven't installed my amps or sub (mainly cause I can't justify buying them with a baby on the way). I went ahead and built my amp racks, fiberglassed my sub enclosure, and pulled out the whole interior and wired it all up. You may want to go ahead and throw some extra wire in for things like interior lighting or data acquistion stuff if that's in your long term plan.

Get yourself a nice bushing for running your power wire through the firewall. I bought mine from cardomain for a couple of dollars.

If you have to drill a hole in your firewill to pass your power wire though, insert one of these guys in there and it will prevent the firewall (metal) from cutting through the insulation jacket of the wire.
 
i was told you dont have to drill.

should i run my power wire opposite side of the rcas? im assuming this piece of shorter 4 guage wire is for my ground? damn its gonna be hard to get that into that fuse holder...well maybe not...hmmm...

if it wasnt snowing out id be out there right now messing with this.
 
you can run the wires through the grommet thing. thats where i ran mine. id put some of that electrician tape on the ends of the rca and like they said, dont put the fuse.
 
You may not have to drill. I'm not sure if there is an existing space available in the P5 to run your power or not. If someone who's run it before said you don't have to, I'd take their word over mine. If you do end up drilling though, get a bushing.

I always run mine as far apart as possible. And whenever you have to cross wires, try to do it at a 90 degree angle. That will tend to eliminate noise coupling between signals. Oh yeah, try to use a single point ground system if you can. It will help eliminate noise by reducing ground loops in your system.

Yes the shorter 4awg is for your ground. Make it as short as possible.
 
when would i have to cross wires? so can i just the speaker wire straight to the back or do i have to go to the front first?

damn my amp is coming today all i need is the speaker adapters...i might have to bundle up and go out there :D
 
also how should i wire the speakers...just +/- to +/- on the amp, or is there something i can do to get more power to the speakers, like connected both positives to one wire and both negatives and only hooking up one set of +/- on the amp?
 
damn one last question...wtf is this small speaker wire looking thing attached to the RCA cables? a ground of some sort?
 
He won't need a bushing, thankfully. There's a rubber grommet on the driver's side that you can fit 4ga through easily...I'm pretty sure there's even enough roon to get 1/0 ga in there. That is a nice piece, though! :)

Matt, for your speakers, since you're sending less than 75W to them I wouldn't bother upgrading the wire to the speakers. You'll probably have to solder some extra wire to it in the doors so that you can reach your crossover, but that's about it.
 
bridge...what exactly do you mean?

And that little wire running with the RCAs is the remote wire. pretty nice how that's set-up, eh? :)
 
yea it sure is i figured that out but was too lazy to edit lol...im running the s*** now...i meant like cant you bridge 6.5s like you can bridge subs? like you have 4 ohm 6.5s cant you bridge them to 2 ohms or am i stupid lol remember im not good with audio stuff.
 
Man, you are gonna have such a f'n blast running all your wires. Remember to take your time and do it right! Installation is the best (most fun in MHO) part of a good stereo.
 
If you bridge the front (right & left) together you will get more power. However, you will be running them in mono instead of stereo. So, out the window with your sound quality and any imaging you hope to achieve.
