Subs and amp sat in my garage for a year. I just

It sounds like you are using the blue wire (power antenna remote turn on) instead of the blue/white wire ( amplifier remote turn on) to turn your amp on. The power antenna remote turns off when leaving tuner mode.

Hello.... I am sorry to hear you are having problems. The reason for this is that since you have a stock stereo, the shop (or person) whom installed the amp and subs used a line out converter. What this part does is allows the connection of RCA cables to the factory head unit. Almost all bass signals are always in stereo, so since you were only hooking an amplifier for just subs, you can actually just connect to just one of the rear speakers instead of connecting to the right and left. Just makes the install a little quicker. There is nothing wrong with this as I usually do the same thing in our shop. However, if you are going to be using the balance control, then you will need to go back to the shop and have them hook the converter up in stereo (to both rear speakers). Hope this helps!

wrap a striped speaker wire around the back of the rca out put on your cd player and for the record that aint a 2300 watt amp its like a 300 watt amp

this is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....

Hello,

I've got a pair of these MTX's subs powered from a Fusion 450 watt 2-channel amp. For the price, they are great. By the way, they are 4-ohm.

My first suspicion would be that something in the first incorrect wiring damaged either the amp or the subs. Can you explain specifically what the "installing the subs incorrectly" means? Was the amp output shorted out at any time or was it operated without a load? Either of these conditions will fry an amp and sometimes, the protection circuitry doesn't work either.

First make sure that your amp is still working. Check both the primary power fuse, usually located near the vehicle battery, and the fuses on both sides of the amp. Make sure that when you turn the system on, the power light comes on steady (blinking is protection mode). Test your subs one at a time on a speaker output.

Make sure that the speaker wires are wired correct at both the amp and the speakers......otherwise it sounds like the typical death of a power acoustik amp (great amps, but prone to a premature death)

This sounds like a problem with the head unit output to the sub amp. Are you using a Pioneer head unit? If so, you may have a problem with some surface mounted fuses inside the radio on the main board. Certain Pioneer head units have a common problem with these fuses blowing. They are fuses for the ground on the RCA outputs.

Let me know if this is the case, and if it is I can give you the part number of these fuses and tell you where they are located, but you would need good soldering skills to replace them. Also let me know what model number your head unit is.

Thanks,

Dave

first check that the subwoofer function on the actual head unit is turned up,second check that the gain on the amp is at bout half way then check that it is on a lp (low pass setting)
then check that the boost on the amp is turned up.
please leave feedback.
cheers

did u have your remote wire hooked up right?

The first thing to try is disconnecting ONE of the two subs. See if you get more bass with a single sub than with both. If you do, re-connect the second subwoofer, but reverse the (+) and (-) wires.
