sup bogue. i live in liverpool. ive installed for circuit city in the carsouel mall for about a year (ended up quitting because the manager was a cockface)
but from whati know about IU, they have good stuff for sale, albiet high prices like most stores of their repute, some of their installers are pretty good, but chances are you wont get a good installer. and there are some really shady installers there, that copy down information about people and their cars and what was installed. ive known several people who have had equipment installed at their location and maybe 2 weeks after the install, it was stolen.
i cant proove that it was IU. but im willing to bet that the installers have friends that they feed info to and get a cut of the profit. they do this under the owners nose, so its not the stores fault. just shady\crappy installers.
if you are interested in getting some equipment installed, lemme know and i could prolly save you a ton of money - and get a higher quality install done to boot.
