demonstr8 Posted May 4, 2009 Report Share Posted May 4, 2009 Wassup fella's...is there a way to test a sub to see if it will function properly without actually hooking it up to an amp? i read online somewhere that there is a way to check the phase of a sub using a 9volt battery, is there any truth behind that? The reason why im wondering is because i found a real good deal on a sub i'd like to pick up, but i wont be able to test it on the spot and i dont wanna pay some stranger cash and get screwed ...thanks for any info.

mrwigglezdj Posted May 4, 2009 Report Share Posted May 4, 2009 ohm meeter and check the coils and make sure they read proper ohms, and the battery is only for phase checking, if it pops out its correct if it goes in then the polarity is reversed Quote Americas loudest work van2006 iasca heavyweight bassboxing champion at 150.4 db with 60second average TL8 memphis PR15s,12 memphis PR6.5's coax,4 memphis PR 1inch tweets Link to comment Share on other sites More sharing options...

mrwigglezdj Posted May 4, 2009 Report Share Posted May 4, 2009 ohm meeter, the coils can be badly burnt but still allow power to pass, but the meeter will tell you if they are shit (dont forget to do the ole scratch n sniff.... i smell all subs i buy used before i even put them on the meeter. if it smells burnt then i wont bother with it Quote Americas loudest work van2006 iasca heavyweight bassboxing champion at 150.4 db with 60second average TL8 memphis PR15s,12 memphis PR6.5's coax,4 memphis PR 1inch tweets Link to comment Share on other sites More sharing options...

MunkeyQ Posted May 4, 2009 Report Share Posted May 4, 2009 I've got a little battery powered T-amp which I take along to test speakers/subs out - it's only $30 or so on ebay and it's light enough to take along with an MP3 player. It's only 10w, but that's more than enough juice to work out whether a speaker is fried or not. Quote Link to comment Share on other sites More sharing options...
