if you can afford to get one of the amps you listed you can probably get a jbl-600.1 or 1200.1 the 600 is $200 and the 122 is about $300 and either one of those amps will push just about any subs
will the JBL 600.1 amp meet the needs of my JBL GT-1081 subs and can i run two subs off of one of these amps because most of the JBL amps i've seen are one channel amps. Where can i find the amp for a good price.
yes you can definatly run the two subs off the jbl amp, all of their job bp amps are 1 ohm stable and you can get them really cheap from ebay the 600 is about $195 plus shipping look for a guy with the user name scala1 i have gotten a lot of thngs from him and he is a good guy.
