ONLY ONE SUB IS WORKING

I HAVE TWO 12" DUB MAGS HOOKED UP TO A 600W AMERICAN LEGACY AMP. ONLY THE RIGHT SUB WORKS. I HAVE CHECKED ALL THE WIRES AND TAKEN THE SUB OUT OF THE BOX TO MAKE SURE THE WIRES WERE STILL CONNECTED. I HAVE CHANGED THE WIRES FROM THE BOX TO THE AMP AND STILL NOTHING.

2 12" subs + 600W amp. Turn on, goes boom once, then red light


Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.

600w legacy amp


9 times out of 10 if your amplifire is in protect mode and evrything externaly, like speakers, fuse, voltage, etc. checks out fine then
either you have shorted out output transistors or power mosfet transistors. Basicly that just about what happens with car amps.
It's easy enough to fix IF, IF you know what your doing. First you
need to check the output transistors with a digital volt meter on diode check, If they check out then check your power supply mosfet transistors. I can almost guarantee this is your problem. Very common. I buy non working amps all the time and repair them. Listen to pbabin also he has helped me out. Good luck

Installing The Subwoofers to the amp... etc.


You should go with a 4 guage power wire kit. If your amp is going in and out
at high volume than that is your problem. 8 guage will work but, if you want
the proper current which is your power from your battery, going to your amp
than I would recomend the 4 guage amp install kit or just the main power
wire coming from your battery. If you would like contact me and I will send you
to a very good sight with all the info you will ever need for car amplifire installation.

I have a dub 4001 amp


Take it step wise.

Unplug the inputs and outputs from the amp (be sure to mark the wires so you can hook them back up), leaving only the ground, +12, and remote wire hooked up. Now, turn it on. If the amp light goes red, the amp is broken. If it goes green, turn if off, plug in the speakers, then turn it on. if it's red, its a speaker problem, if green, do the same with the inputs, and you'll have your answer.

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

Amp stuck in protection mode.


check to make sure your ground wire is attached to a clean metal surface no more then 18" away from amp. check all wires to ensure none are touching other terminal. all else fails remove one sub and see how it play, if its works great switch subs. could be a defective amp. if it is the amp and you payed for it with a credit card or bank card you can do a charge back from the bank to get your money back if the store wont replace it. thell the bank "you want to do a charge back cause it wasnt as discribed).
