Hi,

I have owned some Aura Bass Shakers in the past and I really love them
for their low freqency response.

My question is, if I have 2 bass shakers that are rated 50 Watts each,
and I hook them up in series to a 100 Watt sub channel from my
Soundstream amp, would that be OK?

I have overpowered bass shakers before, and they broke, so I am not
anxious to do that again. On the other hand, I have had them work fine
for years when they were hooked up to an Aura 50 Watt per channel amp.

Thanks for your wisdom,

John

Well john, i've recently come into car audio, and i've learned one
thing...watts mean nothing. your question depends on how many ohms your
speakers are and if your amp is two or even one ohm stable. find out the
specs on that and we can help ya out.

Thanks everyone for the help.

These speakers come in different power sizes.

The ones I have are rated 50 Watts;

Specifications: Color: Black. *Power handling: 50 watts RMS/75 watts
max. *Impedance: 4 ohms *Usable Frequency Response: 20 to 100 Hz *Fs: 40
Hz *Force Peak: 30 lbs. per ft. *Dimensions: 6" dia. x 2-1/8" H *Net
weight: 4 lbs. each.

The amp I was thinking of using was the SoundStream 355, which is rated
at 75Watts (for one channel) at 4 ohms, and 150 Watts at 2 ohms.

Never mind, I can get a 4 channel x 50 Watts by Aura that is made just
for these shakers, so that looks like the simplest way to push them.

I really love these things, I have owned several of them, and they are
the icing on the cake for low frequency response.

John

Hey john, its spanky again. after further research into these bass shakers,
the website i found said they are 4 ohms each. ohms are important cause
amps deliver different watts at different ohms. i also found that these
shakers are only rated for 25 wats rms each. so i would watch out for that.
either way two 4ohm speakers in parallel would give you 8 ohms, which might
be beneficial to you if your amp is pretty powerful. however if it isnt,
and is two ohm stable, you might want to think about parallel configuration.
without a model for the amp i cant offer any more than this...i promise.

hopefully with my last bit of info,

spanky

You mean in series.
