You probibly have a bad RCA cable that happend to my on my brand new MTX thunder amp, try that or else move your ground to a dif. spot in the car or add another ground, also make shur your RCA cables are on the opp side of the power because they magnetic power ran through the power cables can distort and some time dammape your subs.

My amp keeps going off on protection mode as soon as the bass starts bumping

check powers and earth, unplug sub and crank it up see if it still goes into protect if it doesnt the sub is too much load for that amp and could have damaged the amp, if it still does it then its a fault in the amp or power problem make sure you have good thickness 4gauge and good earth

Is that on all the time or are you saying the light is on? If that light is always on that just means it's protecting your amp. If it's off and not playing bass then your in trouble

check your ohm load from your sub... that's generally the problem causing protection lights to kick on or the amp to shut down.

Your probably not pusing enough wattage to the amp. Look into buying a capacitor for your set up. and you may need to run a thicker guage wire to your amp.

Compatible amp for subs

hi there. yes it should work providing you have the correct wiring it for it, if you buy the LV 416 enquire about a wiring kit to fit, most will. theyre normally around 20pounds. most amps will be compatible with most subs. i run both my 12inch 1000w off one 1200amp at half power, they kick lovely and i have no problems.

any other quiries please ask
