looking good, can i suggest you make up a false floor tho so its flat, i can see the tyre shape! then carpet this false floor too. other than that its looking good!

reded · 09-01-2007, 08:53 AM

yeah i did make a false floor but it looked $hithouse so i threw it out,
will make a good one when i can be bothered.
i really badly want to get it DB tested befor the comp....just incase it doesnt sound good.

well today out the back of my old mans work i decided to give the system a good crank :sm_headba
and i noticed even after i reversed phased the 2 side subs they dont go as hard as the 2 back subs....

:
i have them hooked up to a 4ch amp and its bridged so they should be gettin plenty of power?

so any idea's of what is going wrong ?

cheers troy

CaRtZ · 10-01-2007, 07:49 PM

enclosure size, ported, power, brand... all of these could be a contributor...

reded · 10-01-2007, 07:55 PM

but the thig is i've hooked the subs up in the boxes with the ports on there own and they went HARD!! so im thinking that the amp might not be powerful enough...:(

CaRtZ · 10-01-2007, 08:07 PM

did i get this right? you put the k/w subs in where the boss ones now sit and the went good? but the boss ones r siht?

if so id say its a power issue....

try swapping all subs so k/w in the sides and boss in the back and see how it goes?

old_mate · 10-01-2007, 08:32 PM

bass cancelling

Hybrid34 · 11-01-2007, 12:19 AM

Ahhh looks very good, but has any1 ever heard of the 2dB gain rule? I wana know more about it.....!!!

reded · 11-01-2007, 08:52 AM

no sorry Pat i didnt make that verry clear lol.
when i was buliding the boxes i gave the subs a test run on there own in the boxes i built, and they sounded great and went hard....
i am thinking my amp is notr quite strong enough..

old mate: how would they be getting cancelled....?

Hybrid34: thanks man never heard of the 2DB rule.. what the hell is it?

cheers troy

HLC · 11-01-2007, 11:03 AM

well the subs are directly opposite each other. the sound waves are going into each other and cancelling themselves out.

Hybrid34 · 12-01-2007, 03:05 PM

well apparenlty this is the big arguement about installing a second sub, If you add a second one, your only going to get a 2dB gain, my friend knows all about it and can explain it in dtail, i'll ask him n get back to you if you like...

castek · 12-01-2007, 04:57 PM

yeh, running different subs, power frequencys etc, can lead to problems. the best is to have all the same subs with an amp each

looks good but. i'll get pics of mine up once its done. nothing like that but

reded · 12-01-2007, 05:57 PM

oh ok thanks guys,
i was out the back of dads work today and i decided i would try and fix the problem, it strated off well because all 4 of them were going hard, the side 2 were throwing correctly and all

and then all a sudden they went back to only working a litte bit..? im thinking my capasator is stuffed because they will work when the capasator is fully lit up but when its only half lit up they wont work properly..?

cheers troy

efgiar · 12-01-2007, 06:25 PM

are you running a fuse or c/breaker, check for clean connections and good earth

reded · 12-01-2007, 06:37 PM

yeah im running a fuse on the 4guage from te battery to the capasator...
or i was thinking it might be that the RCA and the power cable form the amp are too close together??? would that make them not throw right?

reded · 12-01-2007, 09:55 PM

sorry guys for been so stupid i just went outside then and had a play with it, and the problem was verry simple... the RCA lead was sitting against the power cable along the amp so all i did was wrap the power cable in that grey stuff that comes with the wiring kit and moved the RCA lead away from it simple...

thanks for all of those who helped me out with everything from wiring to idea's to just help in general and thanks for the positive feed back. much apreciated

i am finally happy with the result and how it sounds. hope you all like it too.

cheers troy

ROOSTA · 14-01-2007, 10:29 PM

Looks good mate..

I don't know about the 2 Db extra for each sub.. but there is also another unwritten rule which states for every doubling of power you get 3 Db gain.. So another upgrade in the future worth looking at would be a more power amp/ sub combo.. and sell the gear you have already to recompensate some of the $$$..

Well done!!!

Chers,
Nik

reded · 15-01-2007, 08:49 AM

Thanks Nik im happy with it.
Thanks for all the help you have giving me on this boot and other stuff

yeah i was thinking after a turn 18 (2 months) i might upgrade it all to JayCar Precision subs and amps...

thanks.

cheers troy

CaRtZ · 15-01-2007, 09:41 PM

hmmm i have heard the 3dB rule before. i have also been thinkin of goin with some Precision Response subs but i am 2 weeks from moving to Wodonga so funds don't allow lol :(

.... on second thoughts... Hey Nick, u work @ Jaycay dont you? could you do me a deal? ;)

reded · 16-01-2007, 08:59 AM

I've never heard of either of them two rules...
but yeah in a couple of months will be upgrading, just want to see what DB i can get out of this set-up.

cheers troy

ROOSTA · 16-01-2007, 10:51 PM

Hey guys..
I work in the Jaycar Elesctronics Albury Store.. Actually i half manage the Albury store.. LOL.. Anyways.. I am always willing to do deals on our gear.. especially to forums members.. At the Albury store we have one of the best audio displays in the country which i made myself.. I have all of the available subs working in their ideal enclosure off an 800 wrms d class.. i also have all of the speakers Jaycar currently stocks working and demoable..LOL.. except the 6" splits.. which sound the same as the 6.5"s anyways..

And if you pop in i will happily astound you with a 6.5" sub which sounds louder and clearer than most 10" subs.. LOL.. Plus comming in on the right day might also mean listening and feeling my sweet tunes.. LOL..

Anyways.. enough of a plug.. I should prob get back out to the shed.. LOL..

Cheers,
Nik
