I will be installing 3 amps in my 07 Maxima within the next couple of weeks. I have on ARC KS300.4 that will run bridged to my front comps (Morel Dotech Ovation 6, 350w X 2 @ 4ohms bridged), I have another ARC KS300.4 that will run bridged to two Hertz EBX200R 8" subs (350w X 2 @ 4ohms bridged), Finally, I have an ARC KS125.2 Mini that I will be using to power the rear door speakers (ARC FD6025 2 X 70w @ 4ohms).

That being said, I will have a 1/0 run of Monster Cable (I know everybody's feeling about Monster products, but I got a great deal!) from the battery to the trunk (fused). Inside the trunk I will have a distro block to split the power into (2) 4gauge, and (1) 8 gauge to run to the amps. Now, my questions are:

What size fuse do I need to run at the battery on the 1/0 wire run?...and

What is the proper way to ground the amps? Should I ground each amp seperately at seperate spots? Or should I run a ground distro block and ground the distro block with 1/0 at one spot? I know that Pioneers are known for ground noise issues, and I want to avoid that. I've also read conflicting views on the proper grounding techniques....Lastly,

Do I need to run a relay for the remote turn on lead?

I will be powering everything off of a Pioneer DEH-P980BT. I will be using KnuKoncepz RCA's...I'm still undecided whether I will use the Krystal cables, or the Karma cables. I've used the Karma cables in 2 different installs and they worked perfectly.

Any help is appreciated.

These questions have been asked a ton of times before. People would say a fuse to protect the wire. In 0/1 your looking at 250a.

For the ground try out different spots, methods, etc.

A relay for three amps isn't needed imo.


350 x 2 to your front stage. I guess you like a lot of head room. I'll bet your amp will never pushed past 1/4 of the way daily.

my rule of thumb is add up the all the fuse ratings so if you had 6 50 amp fuses across all amps, subtrack about 50 amps so 250amp for the main power fuse.

cause in the real world you are never allways going to pull 300amp and if u did all at the same time it would not be a good thing.

I've got 3-30amp fuses on each of the KS300.4's, and 1-30amp fuse on the KS125.2, for a total of 210 amps. I just got off of the phone with Monster, and they said that the 1/0 powerflex is rated at 150amps, but the guy I was talking to didn't really sound like he knew what he was talking about. This wire has to be rated higher than that, wouldn't you think?

Luckily for you there is a site that has never been updated [ since this basic **** will umm ...never change !! ]

Now here is the shocker , what would you name a site that teaches "BASIC CAR AUDIO" ?

How about BCAE basic car audio and electronics

I've spent quite a bit of time there already. The problem is reading on their site doesn't tell me what has or has not worked for others . What they say about grounding contradicts other things I've read, so I thought I'd ask here, but thanks for the heads up.

Is that monster wire cca? If that's the case then it's basically the same level of 4ga for carrying current.

There are some here who will tell you the shorter the wire the more current it will carry

So if you can make some 12 guage short enough it will probably carry 150 amps

Once you exceed the safe amount of current...you'll know [ trust me ], the song smoke gets in my eyes comes to mind

Negative...OFC, according to their site.
