Hi ive just bought a audiobahn aw121t sub for my car,im just wondering how i should set it up.i have 3000watt silver sonic 4 channel amp (3000 is the peak power), i have mi kenwood 300 watt max 6x9's wired to channel 1&2 and im going to wire my sub to channels 3&4amp.im not sure how much gain i should give my sub exactly becuse i know you can damage them by under or over powering them.as i know from experiance that ive blew a sub up before.im just wondering can one ef them electrical tester things test how much watts are going to a speaker? can any1 advise me on this please thanks jay

This could be caused due to the impedance load being to low. Your amp is stable to 2 ohm load however its very possible that you have your subs wired to a 1 ohm load that would cause the amp to go into protect mode. The subs you have are dual 4 ohm voice coils and would need to be wired in series/parallel. I've included a link that will show you how the subs should be wired.
Hi, if you wire all voice coils in parallel, you will get down to 1.5 ohms. That is the lowest you can go with these 2 subs. Just hook the amps' positive to all 4 positive speaker terminals and the amp negative to all 4 speaker negative terminals. Please let me know if you have more questions, and thanks for using FixYa.
A pair of JH4512-04's can be wired to 2 ohms if the subs themselves are paralleled. There's only one voice coil and it's 4 ohm. If wired in series, the final impedance to the amp would be 8 ohms. They cannot be wired to 1 ohm.
In bridged mode, your 4-channel amp is only stable down to 4 ohms. You can bridge 2 of the channels to provide a relatively low 200 watts RMS X 2. The best power solution for your subs would be to bridge channels 1 and 2 and wire one sub to it. Likewise, bridge channels 3 and 4 and connect the other sub. If you connect both subs in parallel, the impedance will be too low causing the amp to overheat and possible fail.
As for the settings: Low pass filter on, crossover somewhere between 80-100, input levels to match your receiver, and bass boost to your personal preference.
when a sub is blown it usually makes a scratcy or grinding noise if you push the sub in but if its blow it realy wont make much of a sound so it sounds like your voice coil is going out you will want to get this looked at quick or it can get expensive...i had one were it was cheaper to buy a new sub rather than fix it. it can also just be it disorting from too much power. i would never go over the power limit when dealing with 3000 watts, that can get realy expensive quick
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.
