[QUOTE="contevo, post: 8211546, member: 659241"] My current equipment : Alpine MRP-M350 - i got this amp for 40 bucks Quantum Audio QAW12D2 626RMS 12" sub I got this from a friend had it on two 12 box JVC HU bought at bestbuy on sale $40 and wiring kit. I did couple of research, people suggested many options and opinion, I follow it but still not working for me. but I already burn 2 sub, cheap one I got off walmart for testing purpose. I want to do this right I'm not trying enter audio contest or anything like that. I'm aware I have stock alternator, and I'm limited on power output, my friend has 2 12 alpine with 1000 rms amp, everything stock except HU and his sytem sound sweet. he gave few tips setting up the JVC, lowering bass to -6 and setting sub level etc... Today I setup this, and he said put my gain all the way up since is a 626rms sub, and the amp only pushing 350rms @ 2ohm, I set my LP filter to little under 100hz( is this correct?) and bass boost EQ on the amp off, so I turn up the vol to 40 system sound nice and sub sound powerful, but still didnt kill my hunger for little more punch, so I crank the volume to 43, and than my sub goes silent, I have to power off amp and turn it on again get it to work again. only does this whenever i go on beyond 40 volume. Also I couldn't find manual for the sub, how to wire it. because on the back of the magnet it has label stay " DVC 2 ohm " and if look up the model number it states Independence 4 ohm... so I follow a diagram wiring 4 ohm for 2 ohm amp . so what am I doing wrong here? I really can't invest much money at moment probably income tax ill get better amp and alternator but for now I want this. thank you for ya time. [/QUOTE]
