Amp Question

[JDMFreak]

i've searched, but couldnt find anything specific...

ok, so i want 2 amps in my car, one 4 channel amp to run my pioneer speakers, and one monoblock amp to run a 12 inch sub....the 4 channel amp i have already installed in my car working perfectly.

so here is my question....would i be able to use only one power cable with the one fuse from the car battery to power up my 4 channel amp, as well as running the monoblock amp??

so basicly wat it is is that one power cable from battery to 4 channel amp, then extending that cable from the 4 chanel amp to the monoblock...

Hi
Depending on how much power your running.
I would run a 4 gauge power cable to a distribution block with 2 8 gauge outlets,
Then connect each of the two outlets to each amp.
Run one big fuse as close to the battery as possibble.
The distribution block does not need fuses the amps have them anyway.
So to answer you question the easiest way is to go and buy a distribution block, diconnect the power cable from you amp run it to the distribution block and then connect your amps from there.
Ensure the power and earth cables are thick enough.

i recommend that u disconnect both amps from the power cable that comes from the battery and connect that end to a distributor...make sure that cable between the battery and distributor is an 8 gauge cable...had have a fuse on the cable too...ok so now from the distributor, u'll need two 4 gauge power cables, 1 for each amp....and hopefully u know wat to do with the rest like the remote cable and the rca's

i hope i gave the right information...someone confirm b4 this guy blows something in his car

*EDIT* u beat me with a better answer TEGNO1

[JDMFreak]

my 4 channel amp is 800W, and the monoblock amp i'm planning on getting would have 800W output too....atm, i'm pretty sure i'm running a 8gauge cable from the battery with a fuse....can i just use that to the distributor? then have another 2 8 gauge cable from the distributor to the amps?...or will that blow something up??

[TEGNO1]

Na that should be fine as long as you run that fuse near the battery,
i do recommend at least 4 gauge but that should be fine just ensure you earth the amps correctly with the same gauge cable.
Running a cable thats not big enough is like trying to run standard fuel lines on a 1000hp motor.
But dont worry about it too much youll be fine.

[JDMFreak]

r u sure it will be all good??? should i run another fuse between distributor and them amp too??

[IndoStyler]

opps, i ment 4 gauge cable from battery to distributor and 8 gauge from distributor to amps....but yeh....as tegno1 said, 8 gauge cables all the way thru should be fine as long as u have the amps earthed properly....and if u really want to be safe, u can add the fuse between the distributor and the amps, but not really nessecary coz u already have 1 near the battery, and the amps are fused anyway...maybe just get a bigger fuse near the battery

[TEGNO1]

yeah no more fuses,

[JDMFreak]

wats a good distributor?? and how much??

[integraz]

Stinger is good quality, but mostly you are paying for brand name, and most do the same exact thing.

You can get one at Jaycar for around $25 for a fused one.

Also what are the fuses on your amps?

[JDMFreak]

dunno wat fuse i'm using...will look into it later

i was just looking at this 1 http://www.ryda.com.au/Stinger-STEE8-Tee-Distribution-Block-8GA-p/stee8.htm

would that be perfect for the setup i'm going to run??

[JDMFreak]

i think i'm using a 60A fuse or something

[davec]

that would be ok as long as your running a fuse on the power cable to the battery. i'd suggest that u get a distribution block with fuses just to be on the safe side. like what integraz said get the jaycar distrubition block their best value for money.

from what i know... if u want to run power more that 400WRMS... u need to get at least 4 gauge wiring.. if not... then they would not sound on their maximum potential... but it's ur choice... it's gonna be alot more work if u wanna do it... but from what i think... do the hardwork and u'll going to really enjoy it later...

i'll keep that in mind

sounds alright...i'll do some more research

[theseven]

i'll keep that in mind

remember though... it WRMS not max watt... it's different... usually it's on the box of each items...

[JDMFreak]

theseven: so basicly wat ur saying is that my system will still work with an 8 gauge power cable from the battery with a fuse, but it will sound much better with a 4 gauge power cable from the battery with a fuse....am i right??

[IndoStyler]

theseven: so basicly wat ur saying is that my system will still work with an 8 gauge power cable from the battery with a fuse, but it will sound much better with a 4 gauge power cable from the battery with a fuse....am i right??

yeh spot on dude....its becoz u get more power flowing thru in a 4 gauge than an 8 gauge, therefore more sound power....but none the less 8gauge from battery all the way to both amps will still do the job....just not as efficient, or as powerful

[theseven]

theseven: so basicly wat ur saying is that my system will still work with an 8 gauge power cable from the battery with a fuse, but it will sound much better with a 4 gauge power cable from the battery with a fuse....am i right??

yeap... so what's the point ur buying a high voltage amp (expensive stufff!!!) if u don't want to use it to it's max potential??

[JDMFreak]

ok, i got another question now...does it matter wat type of cable i use for an earth cable? or does it need to be the same as my power cable?? can it be thinner or thicker than the power cable??

[JDMFreak]

dont worry, i found my answer....earthing cable has to be same size as power cable or thicker...i should be all set now

[TEGNO1]

Got it
just remember to earth to a good clean earth point on bare metal.

[JDMFreak]

yeah, will do...i'll probably sand down some paint in the boot and bolt the earthing cable there

[IndoStyler]

u have PM if u want free cables

[JDMFreak]

PM replyed...PM me ur number and ur location....i hope ur close to where i live in campsie

[IndoStyler]

pm replyed...i'm in bexley north....heaps close to campsie


btw, register urself on to crxaustralia.com if u got a crx and come to the meet ups if u can

I'm running 60A main fuse--->6awg ---> distro---> 2 x8 gauge to 2 amps

I've got 1000WRMS Rockford Fosgate Power amp. Even wired to 1 ohm doesn't even pull anymore than 60A, if it did, it would've blown, i know its not good for the amp, cause big cable= more power to amp, but its just a temp.

I shall upgrade to 0gauge soon anyway.

On the safe side use 4 gauge main and 2x 8 gauge out.

[JDMFreak]

i think the monoblock amp i'm getting maybe 500W RMS....and the 4 channel is 400W max not RMS....so i think i should be fine with 8 gauge cables all the way....i wasnt looking after big sound...just after the deep bass that my speakers doesnt give me

[integraz]

Well if your speakers aren't giving the midbass you want, there are other contributing factors:

What pioneer speakers are they? splits, coaxial?
Are the front speakers mounted properly? vented into door cavity? mdf spacer? sound deadened doors?

If not, then this is the route i would be taking to improve you speaker mid bass performance.

Also look at different enclosure for your sub. Is it sealed ported?

[IndoStyler]

i got a del sol same as JDMFreak...atm i got pioneer splits at the front and 6 inch 3 ways at the back...i get good high range and ok mid range sound...i had to tune my amp and headunit to lower the low range bass coz it doesnt really sound too good when i turn up the volume...i was also after a sub in my boot...i believe that subs in sealed boxes will tend to be louder with the low range or deep bass if u want to call it than ported subs. but also u will need to have the right amp to go with the sub...if u get a cheapo $100 amp to power up a 15inch sub, it may not sound as good as a $300 amp powering up a 10inch sub

the amp is the most important, u need to find a monoblock amp that has a few adjustable features on it so u can tweek the sound coming out of it so its adjusted according correctly according to the size of the sub, weather it would be 10, 12, or 15 inch.

my recomecdation is to get a 600W rms monoblock amp and a 12 inch sub with a sealed box. that way u get the low range sound u want from the boot of a del sol...if u want anymore than that, then u will need to upgrade ur power cables first, and then get a more powerful amp and either get 2 12inch subs in a sealed box, or just 1 15inch sub in a sealed box

[theseven]

i think the monoblock amp i'm getting maybe 500W RMS....and the 4 channel is 400W max not RMS....so i think i should be fine with 8 gauge cables all the way....i wasnt looking after big sound...just after the deep bass that my speakers doesnt give me

hmmm it's ur choice... it's hell of cheaper using 8 gauges all the way through i know... but using 4gauge going to be much better sq for sure... like what i said... what's the point ur getting that high end amps if ur not going to use it in it's max potential...

chip in another 100 bux and it all solved...

[theseven]

and also when the time comes and u want to upgrade some more... more amps or subs... u wouldn't need to go all the toruble again putting the cable through from the front to the back...

showcar ready... lol

[JDMFreak]

no need for show car buddy...just want more sound...and more bass that my speakers doesnt give me...btw, indostyler: thx for the cables i picked up today...i'm giving u a trade rating soon

[theseven]

it's ur choice mate... whether u want it there for later use or not... good luck with ur install anyway...

[IndoStyler]

mate, just curious at weather or not if this has been finished...plus any opinions u may have with having a sub in the boot of ur del sol now compared with no sub

[JDMFreak]

dude...sounds pretty good actually...i'm getting some very decent bass now...i'm using 8guage power cables all the way with a fused power distributor as well as a fuse close to the battery...got the 4 channel amp running my speaker setup, and the monoblock for my 12inch sub....i kknow alot of ppl think that the bass cant be heard from the boot of a del sol, but they're all wrong...u actually can hear it as long as the boot is closed...but yeah...if u plan to get a sub in ur del sol, dont let ppl tel u that u cant hear the sub in the boot, coz u actually can hear it...i reackon u can still hear 1 with a 10inch sub with the right setup

[IndoStyler]

sounds sweet...sounds like something wat i got in my boot, but all good...

and i agree with u on the whole thing abt ppl thinking that u cant hear the sub in the boot of a del sol, u so can hear it in the boot...just gotta close the boot
