Hey,

Doing some research on amp wiring as I plan on installing the wiring to my temp amp. If im going to put in the wiring may as well set it all up for any future added amps.

Currently i have:

Aerpro 8gauge 4ch 600w amp wiring kit

Audioline 4x 75w RMS amplifier.

I find it hard to believe that the amp is 75w RMS, but thats what it states on the box...

Im planning on connecting 4 speakers to 1 amp and then buying a mono amp + sub.

My question are:

Will the 8gauge power cable provide enough power for both amplifiers?

Estimating that max 50w RMS per speaker (on the 4ch amp) and probably a 300-400w RMS 12inch sub.

How do i split the power for both amps? I read something about a distributor block?

Can the R32 alternator provide enough current for both amplifiers running on normal volume?

The 600w on the amp wiring kit refers to the max power the power cable can provide? Also the wiring kit has a 60amp fuse, will this need to be changed too?

Thanks for the help!

Alternator will be fine. If you're having issues improve your grounding (eg battery negative to chassis, amp to chassis, etc)

Power runs: Either a single run from battery positive to boot, and then use a distributor block (it's like a splitter) to separate into each amp, or you can make separate runs from battery to each amp. Remember to add a fuse within 30cm of the battery however.

good idea.

thats a start. kit is good for that amp.

My question are:

Will the 8gauge power cable provide enough power for both amplifiers?

Estimating that max 50w RMS per speaker (on the 4ch amp) and probably a 300-400w RMS 12inch sub.

no. it will be enough for the 4ch you have only. if you are doing two I would suggest 4 awg and a 4-8awg distro block at the other end

How do i split the power for both amps? I read something about a distributor block?

correct.

Can the R32 alternator provide enough current for both amplifiers running on normal volume?

it can. when you start getting REALLY big then is becomes a concern.

The 600w on the amp wiring kit refers to the max power the power cable can provide? Also the wiring kit has a 60amp fuse, will this need to be changed too?

how big is the fuse(s) on the current 4ch that is there. if they are BELOW the 60A rating leave it be.

Thanks for the help!

8 gauge will do the job, if the battery is in the boot, but I would probably use 4 gauge for power and earth cables just to be safe, only if you do go the additional mono block amp. If its just the 4 channel amp 8 gauge will be sweet.

If you need to split the cables you can use a distributer block such as in the link:

http://images.google.com.au/images?sourcei...sa=N&tab=wi

This basically makes the cable go in as one 8 or 4 gauge and then spits out as many 8 gauge cables as you need (1 for each amp). These have fuses in them also, but you should still have a fuse near the battery.

You can use one 60 amp fuse, place closed the battery, the cable from the battery to the fuse shouldn't be longer then about 30cm (so Ive been told by many) otherwise it wount protect your equipment as well. If you start blowing the 60 amp fuses easily when you turn it up a bit, go for an 80 amp, and it should be all good. This will all depend on how much power your amps have.

Just make sure you have really good grounding points. This can make or break your system!

Thanks all for the quick responses. Appreciate it!

Chris, the cheque is on the way :)

Time to buy another pair of rca cable, 4gauge power and a distru block.

Now what to do with this 6metre 8ga power cable...

Guess it can be cut in half and go from distru to both amps.

Thanks all :/

possibly. easier though to run it inside the drivers guard and through the main grommet there.

trying to install the amp wiring kit as i post this :pwned:

On a previous thread you posted for a r34:

put the wheel on full lock and peel the inner guard out. that will invlove removing the mud flap and a few screws above it. it will reveal a grommet about the size of a fist.

Is it the same for the R32?

Thanks :O

Just popped off the inner guard to reveal a large rubber grommet blocking my hole :P

Do i pop it out or do i make a hole through it? not sure how to get thruugh this thick rubber...

Edit: Made a hole using screwdriver :) the power cable is finally through ^^,

  • 11 months later...

i'm in need of choosing a 4 channel amplifier and speaker cables.

is there any rule of thumb in terms of determining which gauge wire to use for the speaker/amp combo? (i.e. is it dependent on RMS or MAX?) been doing some research on gauges, impedance, ohms, amps, fuses, etc. and the Aeropro 4 channel kits seem to be what i'm after.

a run down on my current setup.

  • deh p4650mp (has only 1 rca pre-out. should i upgrade to maximize my 4 channel potential?)
  • 35W RMS 4ohms (220W MAX) fronts 6"
  • 40W RMS 4ohms (260W MAX) rear 6x9"
  • would i select for amp rms to match speaker rms (at matching ohms?)

few points i need clarification on.

  • the smaller the number (gauge wise) the thicker the wire and the higher the resistance. correct?
  • you would want to use the thinnest cable suited for your system's power. correct

comparing the 8ga and 6ga Aeropro kits

  • why is the trigger/remote cable & speaker cable thicker in the kit with the thinner power wire?
  • which of the two kits would suit me best, i'm guessing the 8 Ga.? i have no intention of upgrading nor do i want a sub

if all you are doing is a small 4 ch then the 8awg kit will do fine. the 6 awg kit will have more speaker wire in it though.

as for AWG structure:

lower number = bigger cable = less resistance ( you had 'more' in your points)

for power that works well. for speakers - anything over under 16awg (numerically) to me is overkill.

questions - ask/ring me >_<

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
