I have 2 used 15'' kicker xpl subs, both have the same issue, i hook them up to my amp which is 1000w xplod, before i had a mtx sub hooked up so i know everything is in working order, but the kicker subs will play very faint but the subs arent hitting and are very quite, any ideas?

SOURCE: one hits harder then other

Check the Polarity on the subs, you might have to invert one. Best way i know of to test is get a BASS CD -=download a bass test cd...legally of course=- and check for a test that will just flutter the speakers in and out and see if they both go in and out in the same way, if one is in and the other is out that could be your problem

hi, your amp seems to be getting power but the cables might be wrong so it's not getting enough power. the light on the amp should be green if everything is going well. are you sure the cables are suitable for your amp?

check your fuse up front first. some amps will turn the light on with only the remote wire (the 12 volt signal from the head unit). That may be your issue. If not you need to check your signal input. try hooking the rca's to a diffrent source, i.e. other radio your tv anything with Rca out put. If still you get nothing then pull your subs out and take a regular 9 volt battery and touch the leads to the positive and negative of the sub. Just for a moment though if the subs move when they come in contact with the charge from the battery then my last suggestion would be to take it to a store where you can have an authorized tech check out the equiptment. Good luck

I think the electronics have a 3 years warranty and the drivers have a five years warranty for this product, maybe you can have it replaced. Maybe the auto on/off signal detector is the culprit.

I have the same problem with mine and since Acoustic Research went out of business, I too have been looking for a solution. I may have found an alternative to throwing away this really nice speaker. I found a company on the web that appears to sell an amp that may fit nicely into this speaker enclosure for $99.00.

UPDATE Feb-16-2016: This Amp is still going strong since 2012 when I replaced it. The price has gone up to 139.00, but may still be worth it to replace a bad one given the cost of Sub's today.
