wiring subbbbb without amppp??

[vk.jonno]

hi as the title says i was wonderiing if this is possible?
And how would i do thiss?
I suck with wires and electrical stuff so
in the simlest way possible please??

[nathanVY]

no. you need an amp.

You could wire it to a rear channel of your head unit, but it would be lucky to get 18wrms which would not even move the sub, and chances are the h/u doesnt have a low pass filter so it would act like a giant speaker.
Pretty much as Nathanwright said.

You need an amp.

Yes it can be done, but under no means should you do it. Wiring a sub directly to the head unit, to either of it's channels, would give you at the most, 12-15 watts rms.

EDIT must have been typing at the same time as the other replies.....

[vk.jonno]

no dramas.
As i said i have no idea about electrics hahaha,
thanks alot guys

[nathanVY]

if you post up the specs of the sub maybe someone can suggest an amp to power it. if you need a hand with the wiring ill come round if you're near me.

i did for while, if you set fader to the rears lol, it gives out more bass then any 6x9's can, but no where near an amp

[vk.jonno]

ok ill put some specs up
its a candence 'fx series'
350 watts(rms power)
700 watts(peak poower)
and then its got 4ohm impendance and FXWB121-4

btw i just read that off the back i have no cloe what any of it means.
Then i just got a shittty sony xplod speakers and headunit
which actually work really well just gota tune it right

As the others have said, you need an amp. For that sub I'd buy a 2 channel amp and bridge it so it's a 1 channel amp. Since the sub is rated at 350Wrms, you want an amp that does that much or a bit more. Since you have a low budget, this is probably the best value for money you'll find for a new amp. Otherwise you'll be looking at 2nd hand.

And in reply to the others saying you'll get no or very little sound running a sub from the head unit, look at this:
It's rated at 93db 1W/1m, so...
93dB @ 1 W
96dB @ 2W
99dB @ 4W
102dB @ 8W
105dB @ 16W
108dB @ 32W
111db @ 64W
114dB @ 128W
117dB @ 256W
120dB @ 512W

You do get quite a bit more sound with more power but 105dB at 16W is still fairly loud before you take into account cabin gain

lol, what do u mean by 'bridge it' ?? :P

well that was cool ! :P

well so basically long story short i put positive into one channel
and the negitive intot he other channel

[StoneX]

Yeah, but you need to read your amplifier instruction manual or the amp will have markings near the speaker terminals to indicate how to bridge it.
