i have 2 questions as the title states.....
1. Im planning on running 1500 watts, and i heard that RCA cables matter.... what kinda RCA cables do i need for good sound? can i get just some average monster cable RCA?

2. and w/ that kinda watt, what kinda fuse do i need? i heard 100 amp is fine? is that enough? a wafer fuse? or do i need 160 amp...

 

size of the fuse you will need will be specified by the amp's owner's manual.

 

I have rockford its really good sound, they have a wiring kit available. Its like 50 bucks. Don't run the rca and the power on the same side.

 

you CAN run them on the same side if you want to. it's really up to the person installing it.

 

i didnt receive the amp yet, so i will look in the manual when it arrives. just trying to get a jump on the stuff i need.... and what happens if i run them on the same side? if the audio cables are shielded would it stil lbe affected/

 

at 11 volts it will draw 136 amps
at 12 volts it will draw 125 amps

You will need a 150 amp blade type fuse.

I seriously hope you replaced your alternator(110 amp stock) with a bigger model and beefed up your grounding system, or this is going to get messy.

 

It depends on how well the shielding was done, but if they are shielded well, you shouldn't have a problem. The shielding's ground is the most important aspect, which is kind of tough to protect in such a small enviornment as a car. If your ground is clean, then you could run a 150,000 volt line next to the audio line and it wouldn't matter.

 

you can run the rcas for a sub the same side as the power wire...the frequency at which power wire causes interference is a higher frequency than what your sub will even play...obviously then you do NOT want to run your rcas for speakers next to power wire...almost any rcas, no matter how well shielded, will still be interfered by a larger power wire (0 or 4 gauge)...

 

i'm running my rca's next to my 4 gauge...no problems here...

 

3 pairs of RCA next to 0gauge. Also no problems.

 

I'm using monster cable micro xln. Its great because the cable is small, but the plugs are delicate.

 

I have the Stinger Dream series RCA's...very good quality, but a little $$$
