cotoaudio

I bought one of these about a month ago.. I modded a number of the original SI's so I was looking forward to this one. I have a number of commercial amplifiers to compare these to. . www.cotoaudio.com/duke (see reference equipment link) I am running it off a 12v battery.. bought it at Radio Shack the Alarm backup battery 12v 5ah.. $26 bucks. Bought a cheap charger at an auto parts store. $20. make sure you get one for these type of batteries and not a car charger.. You can get a battery and charger cheaper online or even an autoparts store).. End results... For $130 bucks plus $50 for the battery/charger Forget about it.. Absolutely no brainer purchase.. This thing kills.. It would cost you a couple of grand to get this sound.... I already swapped the RCA and Speaker jacks with Cardas jacks. Welborne labs has great prices.. Sonic Impact makes it easy as the holes are drilled for the bigger speaker posts( What a relief) and the RCA jacks go right in. I just snipped the round connectors and put them over the bigger jacks and soldered them to hold them in place.. Took me about an hour to replace all of them.. No stress no mess.. I will probably replace some of the Caps and the pot with an Alps once I have time... but for now.. The amp is driving the Lowthers and it is all good... Actualy very good.. Good luck..
