Yes another amp question

[95RollaLX]

I was reading some past discussions and came across where a guy was talking about his MTX81000D. I thought you said that this amp could power 4 MOMO's? Was this correct? Or maybe at least three while its running with 14.4 volts cause then it pushes 1500watts (supposibly). Also if it doesnt, I was planning on getting an additional 2 12's if I need to get another amp and connect them together does it matter if its a different amp, my friend told me that if u connect 2 different amps together it will sound all messed up. is that true?

Also, everyone says to put a fuse within 16 inches of the battery. Why? What does it matter if its next to the battery or in the trunk.

With this configuration and having this amount of power, I would suggest wiring the subs in a series / parallel configuration. This will achieve a 4 Ohm load and the amplifier will run cooler, plus the subs will sound better due to maintaining a high damping factor which controls excessive cone movement once the signal has stopped.
The purpose of installing a fuse within 12 to 16 inches of the battery is to protect the lead in cable and your car. I worked on a vehicle several years ago that a customer had a Yamaha Car amplifier ( I know I'm geezin', its an old folks thing!! You thought that they made home audio, band equipment, boat motors, and motorcycles. ) installed into a '89 Taurus wagon, and the installer did not install a fuse onto the primary lead in cable and he terminated the connection by using a "block" that pinches the outer insulation of the factory battery cable to make a connection to the positive terminal to the battery. Well needless to say the amplifier's power supply failed and since there was not a fuse installed, the cable acted like a toaster and burned the wire, the interior sill plates, kick panels, and the carpeting. All because of not taking the time to do it right the first time. they were in too
much of a hurry. Save now, pay later.

Happy Fuse Installing!!

isnt the series/parallel configuration where u take 2 of the speakers and hook the pos to pos and neg to neg and connect em to the amp and do the same with the other two?

If you connect two amps together will it get distorted because of different responses and stuff?

That wiring method is a parallel configuration. With a series / parallel wiring you connect the positive to one woofer and the negative to the second woofer. Now you are left with a unterminated negative from the first woofer, and a positive from the second woofer. Simply connect a jumper wire to both of these terminals and this will complete the series circuit. This will result in a 8 Ohm load. Duplicate this method for the second pair of woofers and parallel both sets of positive of negative leads that are running from both sets of woofers and connect them to the bridged terminals on the amplifier. The amp in turn will see a 4 Ohm mono load. The amp will run much cooler, live longer, and sound better.

Happy Wiring!!

Do you think that connecting the four MOMOs to that amp is severly underpowering the subs? Whats the minimum wattage that these subs can handle without harming them. Cause I know I have blown a sub from underpowering it before.

This amp will power the 4 MM120's just fine using a series / parallel wiring configuration. Plus you have the additional gain from using multiple drivers.
Just keep a bottle of Pepto in the glove box.

Good Luck!!
