Item(s) for Sale:

Crossfire XS 8K (12v model)

I am the 1st owner and have had it on a strong electrical.
Nothing wrong with the amp I just need more power..
I have 100% feedback on E-bay and plenty of references and feedback on multiple forums. If you would like to see them just let me know..

Clamped over 10k out of it. With a starting voltage of 14.9 dropping to 12.9 and a nominal impedance of .5 and reactive of .999
(probably could have gotten more out of it but I gave a few demos before I clamped it so batts were not fully charged)

Item(s) Description/Condition:

Here are some specs copied and pasted from the Crossfire page.

The XS-8 amplifier is a raw power machine capable of INSANE POWER LEVELS. The amplifiers circuit board is based on years of high power research and development along with years of experience to make sure every XS-8 amplifier will perform beyond expectations. The XS-8 was designed for competition SPL vehicles in mind, and ridiculously loud street beat machines. The XS-8 is designed and built without compromise, to deliver the strongest amplifier possible.
Many years of R&D have been focused on improving the efficiency and durability of such a high-powered amplifier. We have developed a power supply designed to extract maximum power from real world battery voltages, and produce INSANE power when voltages are taken up to the 18-volt range. The Mosfet and output legs are hand soldered to handle the extreme current demands, and ensure reliability. Power supply connections are handled by 3 sets of 0 gauge connectors for maximum current flow.
We offer 2 versions of the XS-8 amplifier, models are the XS-8K, and the XS-8X. The XS-8K power supply was designed for the STREET CLASS SPL competitor or the daily ground pounder when voltages are under 16 VOLTS or less. The XS-8X power supply was built for the EXTREME HIGH VOLTAGE competitor looking for maximum power at 18 VOLTS. Therefore, whether you have an extreme vehicle looking to break 180 DB or a street vehicle pounding the pavement, CROSSFIRE has made sure we got you covered.

No.. Crossfire has been around for a while. FI does do some OEM subs for Crossfire though. But other then that its 2 different companies..
