can someone explain the severity of having good wiring? an head unit

i have swap meet 4 gauge an it always sounded good but i heard half assing anything on your system will cause some slack an idk..

 

As of now i have 4 gauge wiring power ground an some regular black rcas lol so i plan on running either 0/1 gauge like a good brand,,better rcas,,

an replacing my cheap Fahrenheit dvd playing head unit to something with at-least 4v output!

anyone car to explain or discuss there opinion..

 

 

also i have a sundown saz 2500d amp i plan on either a fi/sp4/btl or dc level 4 or xl 1 18 with a huge ported box(i have a van)..i have one yellow top optima the big three upgrade an a upgraded 200+ amp alternator!

 
Good lord sir running your 2500d off of 4 gauge could be dangerous. using to small of a wire can make the wire heat up and not transfer current as efficiently meaning you will have a voltage drop or not sit at the correct voltage. If that 4 gauge is of really low quality it could get overheated and begin to melt. If I were you I would deffinitly invest in a good run of OFC 0 gauge wire for your power and even maybe get a run for the amp ground up to the battery negative but that may be over kill. I think its funny you have a 200+ amp alt big 3 and a yellow top yet your using 4 gauge.

As far as RCA cables dont go and buy a thousand dollar pair of them just get a nice twisted double shielded pair. These will keep out unwated noise

 
It's called a system for a reason if the system isn't setup properly have the right gague wire and stuff this "system" will not be 100% complete and that will cause to mass failure subs, amps etc....

 
all of these comments are correct ,in your case .the wire just wont give the correct amount of power your amp needs, the deck is flee market garbage,at best,and the rca's aren't designed to take the current flow that you can introduce with the correct amperage and voltage from your system,they need to be shielded and the regular black rca's just are not.sounds like the alt and maybe even the batteries may do the trick.if you want a dc sub or a better one in general hit me up.

lol well my wires have never gotten hot so all of the first comments i appreciate but are wrong in my case ..

but i am gonna upgrade my hole wiring to 1 or 0 gauge also some new rcas a new atleast 4v output radio aswell.

like i said ive always ran **** like this its worked an banged for me i just wanted ur input but thanks anyway.

my low the sub i want i got a better price direct 500 shipped for xl with extras new, thanks though

 
i'm the dc rep for nor cal,if there is someone telling you a different price than what i quoted ,i'd be careful he has no authority to give that price,it may be a used woofer or an m1 .tell him to send you a pic of the motor.

 
the rca's aren't designed to take the current flow that you can introduce with the correct amperage and voltage
Did you mean to say "rca's"? Current flow in RCA is extremely low and isn't even something to consider.

Joe562MMA, there are many reasons to upgrade the head unit, but going to higher voltage RCA outputs is not nearly as important as the hype. It's commonly believed that an amplifier will make more power more of the time with a higher input voltage, but it isn't true. If the amp can't perform correctly with 2V input the gain isn't set correctly.

Another issue here is whether you really do need to upgrade your RCAs. All you really need for good signal transmission is good fitting barrels and low resistance connections. You can check this with an ohm meter, looking for resistance as close to 0 as possible. Foil shielding and twisted pair construction don't do enough to reject noise in the car. You get those features on RCAs to justify the higher price.

you are correct here trumpet ,what i meant was the shielding or lack there of in the rca's he was using can and wont protect from noise ,ie engine or alt noise.

 
With my 4 gauge stinger hpm on my old phoenix gold xenon 1200.1 i could feel a slight warmth on the wire, so there is no way in hell your wire is cool as a cat. 4 gauge is good till 1500rms than it is time to upgrade.
