Just bought a used CE-1000. Wanted to add CEAS2 onto the amplifier, wondering where i can buy the CEAS2 and have it professionally installed or if i can install it myself if it is not difficult. I live in San Francisco, CA. I actually checked guitar center but unfortunately they are out of stock and it will take 4 weeks for the product to come in and i wanted this to be done ASAP. If there any other alternates you can provide it would great. Also does the fan for CE-1000 turn on when you power on the amp? or does it turn on only when in use? i tested it for 10 minutes and the fan never turned on at all. Also since i bought this used am i still covered within crown's warranty? My S/N : 669482 9118. thank you.
