AMP install question! VIC

[tsxl]

I have a 4 channel AMP installed and wired in the car. Using Aerpro bassix 8 gauge power cable. Are the cable anygood?
I want to add another 4 channel kicker (KX600.4) amp and for a 10 to 12 inch jL sub. I was told to use a 2 ways distribution block. But here a problem the sale told me the 8ga wire will not suppport 2 amp. He say the wire might melt. Anyone tried before? I dont want to rewire it. If that is a must! how much would cost? I don't wanna spend too much. I live Melbourne.

By the way i am using a honda battery.

Have any have an opinion?


Cheers.

use a lower guage cable.

4ga.

how much power are the amps and how much current are you drawing??

how much power are the amps and how much current are you drawing??

I have 4 channel 600watts and i am adding a

kicker AMP

•2-, 3-, or 4-channel output
•Tri-way capable (Tri-Way crossover required)
•75 watts RMS x 4 at 4 ohms
•150 watts x 4 at 2 ohms
•300 watts x 2 in bridged mode
•speaker- and preamp-level inputs
•front and rear high-pass/low-pass crossovers (variable 50-200 Hz, 12 dB per octave)
•front/rear bass boost (0-18 dB at 40 Hz)
•remote gain control with 25-foot cable
•frequency response 20-20,000 Hz
•requires 4-gauge power and ground leads — wiring and hardware not included with amplifier
•unregulated Class A/B power supply offers a massive increase in power at 2 ohms
•22-9/16"W x 2-5/8"H x 10-1/4"D

I am only using this amp for a 10 or 12 inch sub. I think i will be getting JL Audio..

well those specs say that amp needs 4ga wire anyway, so it might be an idea to run a separate power cable, or at least upgrade your existing wire.

what happens when you use smaller wire is you actually have more losses in the wire because of the larger resistance of a smaller wire. those losses cause the wire to heat up and eventually melt. using a larger wire can both dissipate the heat better AND heat up less for the same current draw. hence why you need to use a lower guage (thicker wire) for higher powered amps.

but you do need to put new wiring in. the cables that you already have wont be bad. they will do the job well for your other amp. but you will need to upgrade the power wire for the other amp. any wire should do fine, as long as its installed properly. OFC (oxygen free copper) would be the best though.

[tsxl]

Frist thx for your reply. The information was given very clear. But here is the thing, I don't want to pull my car apart again and rewire it. Is there another way.
Because the wire install i done before already have sound coming out from the door when i turn up the music. If I rewire it, it would make it worst.
Do you think I could use the cable that i have now and use a distribion block (1x8ga in, 2x8ga out) to run 8ga to each of the amp? If it end up melting the cable then I will rewire it after! Have anyone try it before?

How much does it cost to rewire?
Any where good and good for budget? In Melbourne?

Thx...

only way is to pull the car apart and rewire it all.

not sure what you mean by "Because the wire install i done before already have sound coming out from the door when i turn up the music. If I rewire it, it would make it worst."... but upgrading the wires wont have a negative effect on the speakers in the door, definitely wont make it worse.

if your distro block only supports 8awg in & out then obviously you'd have to change it. change/upgrade the wiring too. dont wait for things to stuff up & melt, then having to go thru the hassle of doing everything all over again, costing more money in the end.

even more reason to change it if you're getting a pro to do it. upgrading your wiring should be easy for em, no matter how complicated your wiring/electrical system is.

which side of melb are you from?

[tsxl]

Wantirna, around knox city.
How much does it cost just to wire it up?
I can go any within melb. Anywhere good and good budget?

look my friend since you only running 8awg cable I guess you only using 60A fuse under the bonnet, your cable won't be melt coz the fuse will blown first before the cable melt, so my opinion just leave it and try, 100% you won't melt anything

BUT if you keep blowing your fuse when you pump it really hard then you can think about rewiring it

[tsxl]

Well i've your word. I will give it a try and see what happen!

[vtecprelly]

shouldnt melt unless ur pushing stupid amounts or power. im running 8g on mine and i have a fusion powerplant 1000 watt amd and a pioneer 300 watt amp. never had a problem. but i still want to upgrade the wire.

id run with 4g tho. just better flow especially if ur amp and battery are at opposite ends of the car

[redefine]

look. tbh, the specs are always safe. usually done for the system constantly running at full power, which in an audio setup rarely happens (usually only peaks at that at certain times, and runs constantly at a lower level). so you will probably get away with still using the 8awg cable. using the 8awg cable for both amps will result in a less efficient system and slightly less power as you would get with 4awg, cause you'll get about 1v total voltage drop.

you wll probably get away with it...but if it were my system. i'd use the 4awg cable.

rewiring isnt that hard once you already have it wired. all you need to do is somehow attatch the replacement wire to one end of the current wire, and pull the other end. as the origonal wire is being pulled through, it should bring with it the replacement wire, which is much easier then doing it the first time.

[tsxl]

I am please to hear " Give it a try " or i can get away with it!
Look i will give it a try. If the sound goes abit .....* I would rewire it. That what i was thinking.!

Thx.

Woo good to hear someone done something like this. So what speaker and sub have you got?

I have a
VR 504 – 600 Watts 4/2-Channel Reference Amplifier +
Jl Audio - VR600CSI Component Speaker System and
Jl Audio - VR525-CXi Coaxials

Friend just give me a 4 channel kicker (KX600.4) amp
I just wanna run a sub on it.
I like JL sub. I think i'll get 10 to 12 inch sub.
What do you think?

[redmugenjazz]

i would suggest you run an image dynamic idq10 sealed box for a jazz, its decent priced for its quality i is able to produce a deeper tight base and also use a QUALITY amp (JL slash series mono or bridge 2ch, old school soundstream reference series, audio system twister series) for the sub otherwise a JL would be more powerful and produce tighter bass around 80 hz - the kinda bass u hear thump on ur chest at the clubs. The reason why i recomend u use a high quality amp is that i tried to run my friends alpine v12, cheap ebay amp, kenwood 800rms mono (yea right), the sound is flat and will distort when a loud bass note kicks in. then again, sound is subjective, i listen to rnb a bit of techno so i prefer a deep more tighter base for rnb but its up to u.

[Addictions]

either way to split it and have god quality sound from all components it would be recommended to use a 4 gauge cable then split it with the distributor and from that use the 8 gauge cables.

[tsxl]

Anyone have anyother opinion?

As aka_NSX suggested as long as the cable is appropriately fused close to the battery it should never melt. Fuses need to be chosen so that ratings allow enough current to flow to avoid annoying blown fuses, but low enough to protect the cable from being set ablaze

id run with 4g tho. just better flow especially if ur amp and battery are at opposite ends of the car
difference in resistance (resulting in power loss through heat production) over short runs of less than 5 meters should be negligible. If the cable you're using is capable of carrying sufficient current to power your amplifier(s) then there will be little to no benefit in upgrading.
