I recently had a system set up in my xterra and i had purchased a dual 2ohm Fi Q 10" to be run by a cadence iA7 amp. (see following link for specs on the amp: http://www.powermaxelectronics.com/product...amp;idcategory= ). The box was built to be stealth in my xterra and is a sealed and i was told built to house about 0.4cubic feet. (middle of recommended area for this sub) that said, they told me the measured resistance on each coil was ~1.5 ohm so they set up the system to push 3ohm. however, it seems that the sub is rather flat or not quite as responsive as the installers would have expected. i was told that this amp doesn't have enough power for the sub but in talking to others about the amp, they said it should easily push 550rms at 4ohm and 700rms at 3ohm. he suggested checking the wiring just to make sure it was wired correctly. so my questions are as follows: for those who know the sub well in this forum, does it appear that amp i currently have should be sufficient? what is the best way to set this sub up based on the amp i currently have (with respect to series or parallel on the wiring)? and in general have i really purchased a good fit sub wise for the box/amp i have? thanks in advance for any help!!!!
