someone probably asked this already, but is the stock stereo pre-wired for an amp??

nope, only the bazooka

awww fawk...is it JUST a sub only or specifically a bazooka tube?

awww fawk...is it JUST a sub only or specifically a bazooka tube?

i think its for a specific model


its very low power, i believe its for the EL models

the wiring for the bazooka is too small for any decent amp anyway. just run new wires. it's not that hard.

eric, didnt see you at the meet

yea i know...but im too lazy at the moment to run my own wires...and i dunno if the stock deck can handle my sub...and i don't really want to change the deck...

holy old thread

why bring this back????

Whoa hold up... are there signal wires in the back that provide a low-pass signal?

no ned an LOC

Line-out convertor... so it's speaker-level low-pass? Some amps can accomodate that

I was just thinking about this, I want to run an amp and 2 10's in the back, does the deck itself have line out ofr subs or any other rca outputs?? or as stated above, do i need LOC

If your amp can take a high power input yes you do not need an LOC however it will always sound better using one

see above

yeah i was reading another thread and found my answer..thanks for the reply

Just FYI, the Bazooka harness is SEVERELY inadequate for any reasonable amplifier. Stay away from it and run a decent-sized wire with a high thread count for your power and ground. Your amp will thank you.
As for signal, you can use high inputs if your amp supports them, or you could use LOCs. Either way, you're going to be susceptible to signal noise, either at the speaker inputs or at the LOC itself. Keeping the speaker wire run to the LOC as short as possible and using a shielded RCA cable will minimize the signal noise possibility as much as possible.

...using a shielded RCA cable will minimize the signal noise possibility as much as possible.
I disagree. Using a shielded RCA cable will ensure that if any noise is introduced at any point in the cable, the shield will spread that noise the entire length of the cable. Use a non-shielded twisted-pair design RCA cable to reject potential noise, rather than attempting to block noise with shielding.

that is entirely incorrect. shielded wires are designed specifically to block signal noise that is seen through lengths of cable. do know though that different companies supply only certain amounts of shielding. Monster Cable supplies between 82-87% shielding where as there are other brands, greater in expense of course, that have higher shielding. Mogami cables are designed with 98-100% shielding and are used for Studio applications where the highest noise protection is needed. i've used mogami's side by side to raw high power cables running nearly 4,000watt continuously and never had any problems with static noise transfer or intruding noise signals. Shielded wires are made specifically to provide protection from noise, use a good quality shielded cable and you wont have any problems.

mogami cables are expensive, before anyone asks. you can get them at any local Guitar center, if they don't have the specific type of connectors you want, you can do a special order for about 5 bucks extra for some custom cables in the specific lengths that you need. you wont need to do that with RCA, mogami has those available. you can expect a single 10 foot cable to cost about $20 *when i mean single i mean one cable or "the left" input cable while "the right" input cable would be a second cable*, this is for their normal hi-def line. silver, gold and pure series are of higher quality, generally with the same shielding but with higher conductivity and thus more expensive.

that is entirely incorrect.
No, it's absolutely right.

Why don't you explain, if you can, what's wrong with what I stated? All you did was talk about shielded cables, but you never really provided an argument against what I said.

Do you understand that the shield is a conductor, and that it covers the entire length of the cable? If so, you should be able to see the logic in what I stated. Your RCA cables pass the signal from one end of the cable to the other, right? So I'll say it again, if the shield picks up noise anywhere, it can pass that noise the entire length of the cable. Additionally, you shouldn't get any noise in a Scion if you use a twisted-pair design and the install is done correctly, there's no need for a shielded cable.

that is entirely incorrect.
No, it's absolutely right.

I think what Winter was assuming was that everyone was bearing in mind that the signal is isolated from the shield on these types of cables. Most systems actually run the shield to a ground, which typically keeps the induced noise isolated from the signal all the way from source to reception. Some systems also use a Balanced Line Driver application to reciprocate and therefore cancel out the induced noise.
Your statement is correct, but it goes under the assumption that the installer is going to isolate the UTP cable from sources that commonly induce noise. Ideally, ALL signal cable will be completely isolated from ANYTHING that will induce noise, but we all know that, in some cases, this is almost impossible.
Eliminating points of contact with possible noise sources is the best method of eliminating induced noise. If this is impossible and the signal must come into close proximity with a potential source of noise, using a decent shielded cable that keeps the signal isolated from the shield will help to minimize the possibility of induced noise. Also, minimizing the points of contact between the signal and noise as much as possible will keep the possibility of induced noise at a minimum.
Sorry for any confusion.

^^
thankyou UV7

i didn't have the need to explain in detail as to how a proper shielded wire worked other then the fact that are designed specifically to resist and or effectively cancel out signal noise.

the shielding material is normally ran directly to the main amp ground and is isolated within the amp so that it is to never come near any of the processing being done so that it keeps signal noise to the most minimum possible points. even a system that is completely shielded from all noise will still have noise, you just wont hear it.

that is entirely incorrect.

Glad to see you seem to understand the topic, unlike Winter. :)

I agree a balanced design is definitely best for noise rejection & prevention, but my comments only pertained to standard implementations. Most people don't use balanced cables due to the additional cost & complexity of such systems (compared to non-balanced), and because they're not usually needed in most modern vehicles.

Routing of cables used to be very important (as you indicated), but it's much less so now. I do have to question one of your statements, "...it goes under the assumption that the installer is going to isolate the UTP cable from sources that commonly induce noise", because it leads me to believe you may not understand that the twisted-pair design itself is noise-resistant. The thing is, shielded cables cost more and they're not needed to ensure a noise-free install in our Scions. I'm personally using inexpensive unshielded twisted-pair and don't have noise, and there are many others who've done the same, so there's no need to recommend that people buy shielded. The entire car body is a big ground, my UTP cable is right up against it (and all those moving electrons) all the way from the dash to the hatch, yet I don't have noise, so why buy, use or recommend shielded or balanced-line for our vehicles when it's not needed?

That was the only real point I was trying to make in that initial post in this thread. At least now some of the newbs have more info to ponder, and can make up their own minds about which type of cable they choose and why. I just get concerned when I see misinformation (incl. incomplete info) and recommendations that people who don't know any better might act upon. :wink:

ok, so my schooling was wasted time in my life and the experience i've had is also a waste...

didn't realize we were targeting each others opinions... different experience gives different opinions. my experience is from the live field, not car audio. so for you to target me and say i don't understand is ridiculously.

whatever... believe what you wish to. i'll go on doing what i've always done because it's never failed on me.
