I installed a sound system in my car. I had 2 10 inch subs rated at 250 rms and the amp was rated at 300rms so I only put it at 1/4 power. I've had them all summer and then they stopes last week. I blew 3 25 amp fuses on the amp and the subs where smoking. I replaced the subs with 300 rms rated subs and the exact same thing happened. What might cause the fuses to blow and the subs to smoke? Really need to find the problem because I can't go out spending $300 a week on god damn subs
