Subs sound terrible (Ive tried so many things)

the best thing to do is get in touch with amazon,and see what they can do about it,if you try to fix the problem yourself it will invalidate the garantee!

Make sure that when you hooked up your 4 channel amp to the remote turn on lead it is the same as the sub. Only hook amps to the Blue w/ white strip. The solid blue is power antenna lead and will lose power when on CD, ipod etc and only stays powered when the Tuner is on. Hope this fixes your problem.

Hello meow_mix_666,

If you have tried different amps and different subs with the same result, I'd definitely suspect that you are not getting enough of an output signal from the head unit. Checking the RCA's and perhaps using a different set of preamp outs would be a good idea.

One other possibility that you may not have considered is to check the phasing. I've run into speakers that had the markings reversed and running the subs out-of-phase on a 4-channel bridged would make a huge difference in the bass.

Hope this helps.

you can **** yourself

Hey Ryan I have the same thing dude has and my sound only works when I have my subs are hooked up. Without my subs hooked up I have no sound at all. Do you know how I can fix this?

you've spent alot of money on **** by the sounds of it!!. you should only ever run multiple subs the same brand, power and resistance you can just connect any old subs to a system you need to wire them depending on the load that the amp needs to see. first thing is to try the amp/s on a individual sub to check your amps still work once done check the subs 1 by 1.

you have definately blown a output channel, or power supply. Send it in for warranty.

make sure you have the wires from the amp to the box, and the box to the subs hooked up right... red is positive black is negative

This is a multi-tiered question. First of all, you're going to want to run the subs at a 2ohm load (if the amp is capable) to get the maximum power from it. Use the 5.0.1 for the subs only, that's what it's designed for. Run the cap in conjunction with only the sub amp as it has the largest power requirement. You can not link the two amps to increase output as they are first of all different amps and second of all not designed to run that way. Some amps are but they must be identical.
Set the crossover on the sub amp probably no higher than 80Hz (I like it lower than that but that's a personal preference) and turn the sub-sonic filter off.
Now, one of the most important things about a subwoofer is it's encosure. If it's a properly built box designed for your subs specifically then you should be ok. You dont' specify if it's ported or sealed etc. That would be helpful to know as well as it's approximate size (air volume).
The head unit can also have some bearing on how things sound, as I recall the Sony X-Plod units are fairly decent for the price and if set up properly should sound ok.

If you need further assistance please provide a little more info about the sub enclosure etc.

good luck!

if you are sure its the amp. the problem is internal. but if your not sure, try a different stereo or source of sound to the inputs of the amp. if there is still no sound than it is the amplifier and it could be a number of things.
