Amp Wiring

[Rekin]

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.

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!

no probs. send cheque to address in sig

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

Another quick question

Will the 4gauge wire fit through the existing hole in the R32 Firewall? (the one in the top left corner of engine bay)

Not keen on any drilling...

Thanks

[Chris Rogers]

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

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

Pull that inner guard out and all will be revealed, including a big grommet

[Rekin]

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

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 ^^,

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
