I have a rockville punisher 10” blown,it has a 246 oz motor.are those motors any count.i thought of buying a basket and making it a 15”. Do the build myself.i just dont know who has good voice coils to buy and which spiders to get.the sub has 27mm xmax one way.maybe skmeone can explain which spiders are which.i figured i could build a decent sub for around 200$.can someone give me a little input on this.thanks
