I read that mono block amps give you equal power power no matter how many subs you have them hooked to. I have 2 12 inch 4 ohm subs rated for 380 wats per sub will this give me 200 wats per sub or 400. or what would you suggest in a mono amp to give me close to 350 wats per sub?

Re: will this give me 400 watts on each
Bignatedabal: You can't get something more out of a device than it's rating. In other words, if you have a 400W amp that's all it's going to produce. For example if you're looking to drive both sub spkrs @ 350W each then buy a sub amp with a rating of 700W @ 2ohms & connect your 4ohm spkrs in parallel to the amp. Each spkr will produce 350W of sound if everything is installed correctly.
1 thing to look for in amp mfg's. Look for those who rate their amps in RMS power. This is the true output rating. Many amps are rated in peak-to-peak which seems great but doesn't tell you the real story, unless you know how to do the math to determine the RMS. The better mfg's will take the time to test their amps & rate them properly. Also look for massive heatsinking (the cooling fins). I consider cooling fans to be a benefit as well.

Your amp is under powered for those speakers (350 max. watt). Even if your subs were 2 ohm your amp will only put out 75 watts X 2 at 2 ohms, if you bridge that amp you might be asking for trouble . I'm guessing there both 4 ohm. Look around for a 2 ohm stable mono amp with more power and you won't be sorry. Ray
You can't bridge that amp onto a load lower than 4 ohms. So you can't bridge that amp onto two 4 ohm subs. To get the most power out of your subs is easy. Run one channel to one sub and the other channel to the other sub. 165 watts RMS is plenty for most subs.
Yes, you will be fine. 4 gauge power wire is sufficient for a couple of reasons, the primary one being that most of the companies that are boasting 2000 watts for a 4 channel amp are off brand "web-retail only" companies, and they severely over rate the power output of their amplifiers. Secondly the supposed 2000 watts is peak power and not rms power. Peak power means how much power that amp can put out during absolue climax of the music or during a tone burst. RMS power is how much that amp will put out continously to your speakers or in this case, your subs. If you look at the spec sheet of that amp, in all actuallity you're probably only getting 200-300 watts rms even bridged.
On a side note, if you really want to push your subs hard, you might want to consider getting a mono block or "class d" amplifier and use that 4 channel amp to push your surround speakers. Class d/mono block amps are specifically designed to push subwoofers and will give you the most efficient power out and the best heat dissipation to withstand the output required to drive subwoofers. You'll get better bass and also more adjustability to tweak the sound levels coming out of your subs. Hope that helps.
You cant bridge it to the MONO AMP . You can only bridge subs & speakers to 2 CH & 4 CH AMPS that are bridgeable. Because if it appears that there is 2 channels on a Mono amp its so its convenient for you to hook up 2 4ohm subs to it easily But both channels are actually connect internally together in parallel inside the amp unlike a 2 channel they are separate.
So just connect your mtx 9500 to a plus and a minus and doesnt matter which since all the + terminals of are connected together and - are connected together already.
Whats important is on the side of the sub/box it reads 2 ohms. The lower the ohms the more power the Mono amp will put out. Mono amps are designed to handle 2ohm loads.
If it reads 4ohms The MONO amp is the wrong amp to use cause the power will be weaker. So if you have a 1000 Watt Mono amp at 4ohms the sub will only get 500 WATTS Max while a 2 ohm will get the full 1000 Watts.
If it reads 4 ohms connect it to a 2CHANNEL AMP and BRIDGE IT (connect + of the sub to 1st channels positive of the amp then connect - of the sub to 2nd channels negative of the amp) . The power will be doubled when you bridge it on a 2 channel amp. NOW if it was a 2 ohm sub and you bridged it to the 2 channel amp it will fry the subs and ruin the amp. 2 CHANNELS CANT TAKE A 2OHM LOAD BRIDGED OK.
find the ohms on each subwoofer and how much it can handle. If you have two 4 ohm subs get a powerful MONO AMP and hook it up in parallal. If you have two 2 ohm subs get a (1 ohm stable) Powerful MONO AMP and hook it up in parallel or a powerful 2 CHANNEL AMP but the wiring can be a little complicated cause you've got to connect the subs in series and bridge it on the positive of 1 channel and the negative of 2nd channel for maximium benefit without burning out the 2 channel amp. If you got two 500 Watt subs then you got to find an amp that can put out 1000Watts anything less wont sound good and may burn out the subs because of too much distortion cause of lack of power.
It depends on how you define the "best way". Driving each sub with a separate 750 watt amp will result in about 50 percent more power than having them share the output from a single 1000 watt amp. But with 2 amps, there's more wiring issues to contend with and the adjustments are more complex. The 2 750 watt amps will cost more than a single 1000. Plus if the 1000 watt amp is stable to 1 ohm, the power difference will actually be less than 50 percent because of the lower impedance. But if the 750 watt amps are also stable to 1 ohm and their outputs can be combined, we're back to 2 being better than 1.
I'd say that the simplest, most economical way is to use a single amp. If maximum power to the subs is the highest priority, and cost and wiring is not an issue, then 2 is better.
All amps aren't created equal. More exspense amps put out "cleaner" power. You need to know what the RMS power rating is for the amp at 8 ohms and 4 ohms. Also, is the speaker an 8 or 4 ohm speaker? How you wire a speaker or speakers (series or paralell) can change the ohms (resistence) which will change the power put out of the amp. Also, I'm assuming you are setting it up in mono?
Your subs will share the amp output. And if you are not careful, you'll end up blowing them. The amp puts out 1300 watts RMS at 2ohms, the subs have an RMS power range of from 75-350 watts, and you'll be driving them with 650 watts each. A better power match would be to series the subs to present an 8ohm final load. This will reduce the output power to a level the subs can handle. Or you could buy 2 more 12.1's and connect them series-parallel for a 4ohm load and each sub would still be getting 325 watts RMS, just about the maximum they are rated to handle.
Hope this helps.
