Impedance: 4 Ohms OR 2 Ohms

[Rob182]

Does it matter when look at a speaker?

i want to use a speaker with is 2 Ohms without it being amped!!!

is this ok?

Cheers

Rob

no will kill a hu in no time at all

 

[dannyboy172]

not sure on impedance, whats the sensitivity/range and RMS value?

 

[kpowell911]

what do you mean without it bein amped?

impedence usually mattes with subs, 99% of speakers are 4 ohm.

what do you mean not bein amped?

 

[Rob182]

• Diameter: 5" (13cm)
• Power Handling, RMS: 55 watts
• Power Handling, Peak: 165 watts
• Sensitivity (2.83V/1m): 94dB
• Frequency Response: 55Hz – 25kHz
• Nominal Impedance: 2 Ohms
• Mounting Depth: 53mm
• Cut-Out Diameter: 120mm

 

[Rob182]

it well just be power by the head unit not amp! (i know the head unit is a amp) but i mean not an external one!

 

[kpowell911]

and you want to run that of your HU?

 

[Rob182]

yeah

is that ok?

 

[kpowell911]

no cause your HU is 4 ohm stable, you wil lfry your hu

 

[Dink]

the lower the impeadance the higher the current = one dead hu

 

[Rob182]

so i need to find a 4 ohms speaker?

 

[kpowell911]

yea shouldnt be too hard Most speakers are 4 ohm

 

[kpowell911]

is it the stock renault head unit?

 

[dannyboy172]

What make are they mate, majority of co-axial component speakers are 4 ohms.

 

[Dink]

i'm going to guess infinitys

 

[Rob182]

yeah is it the standard reno HU (cabasses)

and it was the kappa 57.2i speakers i was looking at

http://www.caraudiodirect.co.uk/product_info.php?products_id=4378

but there 2 ohms

 

[Rob182]

i'm going to guess infinitys

Spot on :rasp:

 

[Dink]

they are designed to get more power out of a small amp rather than be run off a hu

 

[Rob182]

thanks all,

glad i asked before wasting £220!!!!

I think i well go for the other kappa with the 4ohms!!

they should be ok with the head unit?

 

[Dink]

these?

 

[kpowell911]

i wouldnt waste my money with expensive speakers if im running them offa head unit, sending about 20wrms too them
