I went to circuit city to check out the Infinity 1230 refs. they didnt have any on display, so i bought a pair with the intention of returning them. i pulled out the one blown sony that i already own first, and installed one ref. i turn up the system like that just a wee bit, and it sounded good. i then took out the working sony and popped in the second ref. i cranked it up this time and there was nothing. i could hear the subs, and could feel a little buzzing, and i could see them moving nearly an inch when they hit, but i couldnt feel sh!t. the one sony i was running b4 hit ten times harder (just to give you an idea how wimpy it was). they seemed to be doing that cancelling thing. how can i stop this from happening in the future. and should i go back and get the 1230s or wait for more money and get kappa perfects?
Before you switch the polarity on the sub, be 100% certain that you got it correct. Last thing you need is another blown sub. It's not that hard, open up the sub, pull out the sub and check. Better safe than sorry.
