You can buy a ground loop isolator or move your RCA cables away from your power cable. Also try a different ground in your dash.

How much rms dose an american pro vs 1409 put out


I used to have a similar model, vs1405, and it was advertised to have 600w max. Its rms ratings were 260w bridged @ 4ohm. and 80x2 @ 4 ohm.
So I really wouldnt expect much.
I would personally suggest the HiFonics Brutus. Very nice amps for the price, and have TONS of power.

I have 2004 nissan maxima making engine noise when starting n while driving?? what to do? i have 79,000 miles on the engine.


Buy a ground loop isolator and hook it up in line on the rcas, that will get rid of the whine. If you ran your power wire next to the rcas it will be louder because it creates a magnetic field. If you have a 4 channel amp you will need 2.

Sounds like the thermal protection on your amp is doing its job. You can put an external fan in to help in cooling, like the crossflow type shown here, or a couple of muffin fans like these (look familiar?). You may have fashion a bracket to mount the fan(s), but that shouldn't be too much of a problem. Many fans are shipped with mounting tabs attached.

Humming noise in amp


You must break it down through a process of eliminating items. With the system running unplug the RCAs from the amp. Do you still hear the noise? Try turning the gain down on the amp a bit and increasing the subwoofer level on the head unit instead. Make sure you have a low pass crossover set (probably below 80Hz).
Does the noise change with engine RPM?
Try a different RCA cable. I find that most times noise filters will make the problem worse not better. If none of the above things work, check that the grounds within the car are good, battery to frame, to engine block and chassis. Sometimes a bad vehicle ground is the cause. If all else fails, hook it up to someone else's system and see how it works.
