The Powercall X71 Siren been updated as of 9/10/2008. The latest version has fixed a few items that I didn't really care for in the first version. The following items have been updated:

1) The current model now gets wired to power, ground and the speaker and now has a separate pair of shielded wires for the Toggle switch.

2) The current model also now has an instant activation. The first version took about 3 seconds to come on once the toggle switch was flipped. This current version comes on instantly.

3) I have included contact tape on the inside chassis in the instances that customers torque down the box too much during installation. I have also included additional spacers between the board and the chassis to help remedy this problem as well.

4) As well, due to the costs of material rising, we have had to bump this siren cost up just a bit. I split the cost in half so it only affects our customers $5.00. Unfortunately, there was no way around this as costs of materials continue to rise and we have added a couple items to this version. It's still dirt cheap for a single tone Powercall Siren and nobody can touch our prices. :)

The Powercall X71 siren has one tone, the Powercall Siren Tone. The unit is a strong 100 Watts with a toggle switch to operate the On/Off function of the siren. The X71 will operate any 100 Watt siren speaker mounted anywhere within your vehicle.
