It isn't wise to connect the business end of amplifiers together so if you want or need to use them together you do it at the input end. It is better to use an active rather than a passive method, simply connecting the inputs together in parallel would work but is not recommended and the results are unpredictable. A passive splitter would be better and produce more control and predictability. It depends what results you are looking for. Clearly it is better if each amp drives only one speaker, especially if they aren't an electrically matched pair. If the amps normally require an 8 ohm speaker it should still be acceptable to use 4 ohm loads as long as the peak input at the front end doesn't exceed half the rated maximum. You could use one amp on each channel for stereo via a suitable preamp or you could use an active phase splitter and use the two amps as a single push-pull amplifier with two outputs or with a front end filter you could make one amp work on the bass to midrange frequencies and one sub-bass to bass frequencies. Some of the stuff is probably commercially available but some would need to be constructed so what you need is a friendly tv engineer or an electronics enthusiast...

Depends on your budget. Look for something that does 300wrms at 2ohms.

Try using a continuity tester turn the amp on as normal play the head unit and see if you get a reading or you can try using a different sub woofer if the problem persists I could be your amplifier then

While the manual controls on the amp do provide some amount of control, the Tweeq app allows much finer control over the equalizer, crossovers, and phase/delay settings.

you really want something closer to 600 watts. if you arent careful, you can overdrive the amp, since the speaker isnt seeming to mind the volume, and the resulting audio distortion can damage the speaker

Check ohm reading of the speaker. Should read close to whatever the spec is (2 ohm, 4 ohm, 8 ohm) if you have multiple subs and no ohm meter then try connecting one at a time to the amp. Either you have a shorted sub, ohms are too low for the amp or you have an (least likely) amp problem tha y only shows up under a load.

Check power make sure you have solid 12 volts. Disconnect speakers, shorted speaker can cause protection mode to engage. If still in protect mode will need to repair. Kicker does out of warranty repairs on kx series amps or try T.I.P.S contact at linearpower.com. Iirc Ray @ tips was one of the engineers at kicker back when kx series was introduced.

Something loose, air leakage, air movement from the cone at certain frequencies.

Try wiring them in series.

if you have connected the power supply up backwards (crossed over plus to minus ) then im afraid you've damaged it internally , but if you have only connected the speakers backwards , that's not too bad . unpower it and ck your wiring to the speakers make sure all the speakers red or + goes to the positive or + on the amp and the negative goes to the other terminal
