Lets narrow it down.

You've go two speakers, one works, one doesn't.

First off, switch the connections on the speakers.

- Good to bad
- Bad to good

Now, if the one that wasn't working, starts working: The speaker is OK

If the one the was working, still works: The Amp is OK

If the one the was working, stops working: Either the amp input for that channel has been compromised (check connections), That side of the amp is blown, or possibly (long shot) the heads balance is all the way to one side.

If they both are working: It fixed itself!!

Hope this helps locate the problem

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

My system just stopped working one random day. the sub will hit very softly every 5- 10 seconds. i think it is the amp. what could it be?


Hello

Well my first thought is that you blew your sub. Does your amp have a power light on ? Is it green or red ?

If you have an extra sub or amp, or a friend does. Try switching one or the other out (sub would be easiest) and rule out which one is really at fault. But im still leaning towards a blown sub.

Post back if you have any further question's or comments. Thank you for choosing Fixya!

I just need to know the best way to hook my amp and subs together. i like a lot of bass. i just bought the subs and yhey dont really sound any diffrent. should i get a new amp.


Hello hembreegerry,

If you like a lot of bass, you definitely need to consider another amp. The SP2X-300 is only rated at 170 watts RMS into 4 ohms mono. That would barely be enough to power one small sub. You do not specify what brand and model your subs are, their impedance, or their power handling capacity. But for any subs, your best power solution is to add together the individual RMS power handling capacity and select a monoblock amp that provides close to the maximum at the impedance they will be wired to present. For example, if your subs are 4 ohms and have a maximum RMS of 250 watts, you would want an amp that outputs abour 500 watts into 2 ohms (2 4 ohm subs wired in parallel = 2 ohm load). An ideal amp in that example would be the Alpine MRP-M500 which outputs 500 watts RMS into 2 ohms.

Hope this helps.

Wiring issues


ok here is how it goes power wire from the battery all the way to amp..then ground wire from amp to a good ground on car then the remote wire which you have to run from the amp to the back of your stereo which in most cases is blue then hook subs from the sub box to the amp

Subs


I looked up that amp, it doesn't have a listing for 2ohms x1 but it has 2 ohms x 2 and its at 250watts. For this situation, I would recommend a different amp or different subs. Right now you are getting the most you can get out of your sub/amp combo, if you only have single voice coil subs. Which is common in the mtx preloaded boxes. Either you want an mono block amp stable at 2 ohms or 2 dual 4 ohm voice coil subs. If you got the subs you would wire the voice coils in series so you could get 8 ohms then the subs in parallel so you could get 4 ohms, which would be the best for that particular amp. Good luck.

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
