Has mtx stop selling the mtx ta81001?

Since this is a vintage item, the cost is whatever the market will bear, wherever you're trying to sell it. I would suggest checking current prices on sites such as eBay, where one is currently being offered to sell at $200, while another is being offered for $90. The perceived value is what determines the selling price at this point, because the MSRP is long irrelevant by now, being that it's a discontinued item.

It should tell you on the back of the sub ,The continus watts it will handle, If not phone the place you got it from, Or some place that sells them,

Check for a blowin fuse or a defective relay, If there good the blower motor is shot, End will need to be replaced,

Try online or ebay Or from a car audio store that sells (MTX) Amps,

NEVER mix different power amps. Depending on the ohms of your subs, sell one of the amps, up to you. The 4001 has more power, but either amp will do the job, the amp needs to see a 1 ohm load, so your subs have to be dual 2 ohms, or single 4 ohms to do this. If your subs are dual 4 ohms then you will have to run your amp at 2 ohms which would be have the power, or a half an ohm, (Not Recomended) and be at double the power. You may be able to do a competion sound off and just "Burp" the subs, but at a half an ohm, dont expect to listen to it to long before it goes into protect and shuts down.

They probally would, but i just found that sub for 51.00 im sure it would cost that and more to have.it fixed

yea at car audio store

MTX never released any of their schematics.

What sort of problem are you having with it?

A large capacitor between your battery and the amp may help. Your alternator is most likely strained by the amp's power consumption. If you can't get a stronger alternator or suitable capacitor, you may nbeed to replace your battery and alternator more often than normal.
