received.:thumbsup:

Anything which does 50 watts per 4ohm load at 12volts will work well to power them.

that amp seems too small. according to their minimal specs, it does 100watts at 1ohm.

You can expect 50 watts rms to the pair.. {25watts each}

It will work, but you could use a true 50watts pers sub to run them and get about 4 times the output.

I have no more new ones that I know of. I just noticed the box and decided to list them for a price I myself wouldn't say no to.
I may sell some lightly used sets soon. I have left overs strewn throughout my life.. a set in my daily driver, a set in old pickup.. extras in misc boxes.

I had 20 total at one time... so there are 14 more somewhere:D

That is what they do.

The sound resonance depends on the panel you mount them too.
The best car application I've used them for was the rear wall of a 1990 S10 extended cab. That truck sounded like it had a pair of subwoofers...nice quality 10s or 12s.

Understanding that Aura Bass shakers act like little suspended sledgehammers creating vibrations might give you a better idea of what they do.

They are an aluminum heatsink housing which a stationary ferrite ring and inner wound coil is mounted in. the coil is an electromagnet which acts on a suspended magnet causing it to move up and down.
More power? nope, 50watts RMS is all it needs to move the magnet full stroke. More power would only create destructive heat.
