There are many LOC's on the market and many different ones depending on your needs but this to me was just all around perfect and the performance IMO is off the charts. I called the company - Audio Control - themselves to ask some questions about the LC2i before buying and there customer service was really good. They were knowledgeable and friendly. My system goes - 2009 Acura TL Base with factory radio, bluetooth, hands free link, 6 dics cd, XM Radio, and USB iPod integration. I installed a 10" Infinity Kappa perfect pushed with a JL Audio HD750/1. The only thing I did was unhook the 8" factory sub and ran the LOC through the factory sub location. This gave me control of the sub through my factory head unit as my radio has controls for the sub alone. I did not have to remove my radio for this install due to the fact that I used the built in remote lead to amp function on the LOC this is one thing that drew me to this particular LOC as I didn't want to run a separate remote wire from my radio or fuse box. I read that this LOC remote wire function gives you the "Subwoofer pop" when first turning on the vehicle but I have NEVER found that to be the case. It is whisper quite at all times with no feedback at startup whatsoever. I have a dedicated power wire running straight from the battery to the LOC and everything else is standard install AMP, Sub etc. The BEST thing about this LOC though is the "AccuBASS processing for correction of bass roll-off" which in my setup works VERY well. It seems to really bring out those low notes that the factory amp tries to roll off and does it seamlessly. I would recommend this LOC to anyone. It has great control at a fair price with easy instal and great features.
P.S. I also installed infinity reference 6.5 all the way around in my Acura TL to replace the factory speaks. They are 2ohm speaks which are the same as factory. This combo with the factory head unit and the sub has been an incredibly affordable alternative to a full system redo and sounds immaculate while keeping all the functionality of the factory system with LOW power drain.
