i ran the 12.4s for 5 months with some heavy abuse finaly burnt out on 1kw each the rms they just over heated and started smoking like crazy, i saw frankb 's left overs of those subs after running 2.4kw each fresh outa the box and they smoked and melted if i remember right, they are a fantastic daily driver they hit prety hard hard but there not good for really loud edaily driving.... how much u pay for those anyways? i wouldn't mind getting some new ones as back ups for when mine blow and i have to struggle with reconing them. i've also only used bassworx amps, run 6 75.2s and 4 500.1s all the amps are still running great, they're nice and loud to me never had problem with overheating all around great amps... can't say anything for the 1200.1 or the 3000.1 but i trust in the quality

 

there 1000 rms 3000 peak but they can really only handle about 2400 if they are brand new after being worked in they can handle 3000 for very short amounts of time and if u resin the cones they'll be able to handle it alot better

 

i ran 2 at 1000 rms on daily and the smoked out my car after runnin for 4 months... but are these peple actually useing them turned up loud enough so that they are actually getting 1000 watts or more? beacuase i kno mine were getting close to 1000 watts and they fried

 

Dude those subs are garbage and Frank was lucky if he had over 5k from 8 amps with the rise he had in his truck. Plus his batts are dead and wont go over 12v so do the math. P.S his amps wouldnt even take 13v so thats the type of product Bassworx is. The only good thing that they make is the 3000 amp Adam is having good luck with them.
