what is wrong with it
nothin ever can just go smooth for me. i have a hifonics bxi2008d which was hooked up to a mtx 9500 after a few weeks the sub started cracklin and not bein loud at all so i think its blown. but also now the amp will put out te first couple thumps of a beat the first time i turn it on for the day but after that it wont put any sound through. the protect is not on and ive played around with all the levels and dont know what else. think i fried it out? i thought usually protect lights stay on or blink when an amp is dead

make sure the input sensitivity on the amplifier isn't turned up too high. Set it to 25% of full to start.
Set the LP filter to about 50-60Hz
Set slope/Q-factor to 18dB/octave
turn off any "bass boost" EQing features
carefully check the integrity of the power and ground cables at all connection points, including chassis, battery, and amplifier.
Check the remote trigger line connections.
After that, also disconnect the sub, and check DCR across the terminals, lightly and gently press on the cone, with fonger tips around the center dust cap, to feel if the cone is frozen, or if it moves freely.
You can also take an alkaline battery with a wire at each terminal (pos/neg) and touch one wire to each speaker terminal (just a quick tap of a touch) and see if the speaker cone moves and if the speaker produces a popping sound.
That will tell you if the sub is severely damaged most times.
