Guys,

I just purchased the RCA cables for the amps/converters. Is 16feet too much? It was a choice between the 10 or 16 feet. I choose the longer just in case.

I heard that the length (if too long) can be a negative to the sound, any comments?

Also, is the cables supposed to be a male connectors (both ends)?

16' is good. depends on where you're mounting the amp also. i think 10' would be a little too short.

yea, if too long, you can pick up noise along the way. 16' is a good length, i use that in all my cars. just don't run it with the power.

 

I put my amp rack right behind the seat btwn the rear speakers and the strut bar. I used 10' and had about 1ft surplus.

 

So long as you avoid any power lines like stu46 said 6' isn't going to make much of a difference. You just have to decide if you want the extra cable wadded up near the amp.

Oh, and I haven't ever been able to confirm or repeat this, but I have heard that if you loop up the extra cable you can get feed back because of the loop (being an engineer I can understand why it is possible). Just FYI

 

Stu,

So you saying to run the power wire separate (not tie them together)?

By the way. I have a mono (Phoenix Gold Octane-R 5.0:1 ) & a 4 channel amp (Phoenix Gold Octane-R 5.0:4 ) . First amp requires a 40 amp fuse, second amp requires 50 amp fuse, making a total of 90 amps. I bought the fuse holder with 80 amps.

If I decided on a HU (alpine 9833), would the fuse holder be enough? I asked the question before, but never got a definite answer. I am running a 4 gauge cable to the battery with distribution to each amp using 8 gauge.

Thanks a lot.

If you have 2 amps I would go with a distribution block downstream of the inline fuse near your battery. That way you will be 1 large fuse (80 amp) and then 2 smaller ones for each of the amps.

And STU did mean do not tie the power and signal wires together. But you must also be sure not to run the signal wire next to a vehicle power line. There are lots of "hot" lines all over the car.


Here's a pic of my distribution block.

 

yea, i try not to. but i'm also running two 2 gauge for power.

 

10' or 16' RCA? I used 6' from the HU to the area behind drivers seat and it worked OK. Ran down the center console.

 

gundam02,

Would 80 amps be sufficient eventhough, the two amps combined to be equal to 90 amps and the Alpine HU might draw more amps?

Tony

 

First question I have to ask is are you sure about the power load of each Amp?
Second if you are sure, are you using an ANL fuse?
Mainly I ask this because I was unaware of an AGU fuse above 80 amps, that is why I said 80 in the post, I didn't recognize that you said you had a 90 amp system.

You definitely want a minimum battery fuse (the main single fuse at the battery) that is at least equal to the total max amperage of your system otherwise when you pull full power on big notes you could overheat the fuse. Now if you don't mind replacing fuses all the time then it's ok

As far as the HU needing even more power, are you not going to use the existing head unit power for that? Are you running a new power lead from the battery to your HU? If you are using the existing HU power lead then don't worry about a fuse to handle that too, that power lead is in the system fuse box. But if you are running a new power line then yes, you will need to consider going even higher on the main fuse block.

Hope this helps.

 

gundam02,

Yes the total of the amps are 90 amps. I have purchased a AGU 80 amps.

As for as the HU (Alpine 9833), I am not sure if i need to run a power directly to the battery or distribution. I will not being using the HU's power. Can anybody elaborate on that model. From what I interpret, if you don't use its own amp, then you don't need to. Anybody know the answer?


Tony

 

You should be ok with the 80 amp AGU, but there will always be the possiblity that you could pop that fuse. So I would definitly keep a few spares in the car.

As far as the HU, I have no idea. Hopefully someone else here can help you out.
