I have 2 kenwood 12s and a 1200 watt amp ( I know it isn't all that great ) when I first bought it all brandnew it hit both subs pretty hard. But now I can only hit one hard. If I take them and hook them up to my home audio they both slam ( the home audio is pushing less watts ). Any help would be great

 

are you running the amp/subs in stereo or mono ?

 

I have it bridged idk what you mean

 

if the amp is bridged (mono )and they are wired correctly one of the coils could
be damaged , I would use a multi meter and check the resistance of each coil

home amps put out rated power at 4ohm or 8ohm so they will push
a damaged coil with a bit more force , where a car amp needs it's 2ohm load

 

So you think one of my subs could are bad

 

Could be bad

 

I have tried them not bridged

 

Alpine Electronics of America, Inc. here is my amp , which sub should i buy because i dunt know about impedence and ohm much , KICKER | Solo-Baric L7 15" 4? 4 ohm is compatible with my amp or 2 ohm is compatible KICKER | Solo-Baric L7 15" 2? , please tell me thanks !

 

If your amp is 1 ohm stable I would go with the 2 ohm
