I am looking at the Acoustic Audio HD728 7.2 (two passive subs). Can this amp drive both subs, or would I need two amps?

It will drive them just fine.be carefull. Might even be a bit to much for them.

yes, you can, but keep in mind that the nominal power for the amp is 300 W, you won't be able to extract more energy from the amp. (300 W is still a lot for a subwoofer!). You might want to connect the two subwoofers in Parallel and that will reduce the total ohms from 8 to 4. You can also connect them in series, but that is going to increase the resistance (to 16 ohms) and that will mean that the transfer of energy won't be optimal (i.e. they will sound with low volume)

I believe you can use the input/thru XLR on this to pass back to an amp that powers the passive speakers. But this will NOT power your passives, if that's the question.

It's not meant to be "hooked up" into a 7.2 system. You really need to match your speakers with your receiver.if your receiver did happen to have pre-outs you take a risk. Of damage. I have a 7.2 system that I've matched speakers to receiver. It has 130w per ch. and will play loud and clear enough for our neighbors! This amp is a 2 ch amp meant to be played in a stereo system ( 2 speakers). Hope this helps

I would expect 2 microphones will work. This is not a "heavy duty" amp. Don't push it too hard. Although rated at 240 watts, we are running outdoor loudspeakers for a total of about 100 watts, the unit really gets hot when we turn the volume up. As for 2 microphones, mic 1 position will mute all other sound when it is active. I don't know of any way to turn that off. You may be able to set up the mic 2 and AUX inputs for 2 mics to be active at the same time.

This amp will be perfect for that, you will want to put two speakers in parallel on each channel, giving you a 2 ohm load on each. Like this http://www.diyaudioandvideo.com/FAQ/Wiring/parallel.gif on each channel.

It has two inputs, but you can only use one at a time, so no. Actually, I use mine to bring my acoustic bass up to the level of an non-amplified acoustic guitar. If you're looking to amplify an acoustic guitar, this probably won't be powerful enough to make your bass keep up with it.

You can run two speakers off of a 4 channel amp but unless you are an experienced car Audi installer I wouldn't suggest running 4 speakers off a two channel amp

You'll have to buy one separate, do it though, this amp seriously is so great. I got it for my DM10 drum kit and have a mic plugged into the Aux port and the acoustics are great.

no. you will not get the quality sound from one amplifier. you will need two amplifier. you will need to know how many watts your speakers are and your amp. should be competible with ur speakers. it goes the same with ur sub..

Yes and no its only a 2 channel amp meaning 2 + and - for 2 speakers you would have to put 2 speakers on each + and -. Like both front and both rear on a + and -.

It's a five channel 2front 2rear, and one sub output. It powers my 1200w 12" Kenwood sub and sounds great. I think if you are looking to power 2 subs you might need a different type of amp. But overall the Alpine amp, this series and the next one above are the best. MRX and PDX I believe are the models. Not sure off the top of my head

This is a Sub and Amp in one enclosure. You don't need a separate amp, but you do need to run power to this for it to operate.

I would NOT recomend this amp for a Sub Amp, at most it would be useful for small door speakers X2 , it would only push out about 25 - 35 RMS clean watts, That's equal to a powerful head unit.

Not sure Paulo, I got the 7.2 because I have 2 powered subs, and 8 surround speakers... needed the power!! may just have an extra bell or whistle that you may not even need.... product description for both should be listed,sorry.

I would.think so seeing as it has a built.in crossover. But i would talk to someone from best buy, or an audio store.to make sure before.purchasing. I only have a sub, and my factory speaker hooked up thru this amp. So I am only taking up two channels. I will say, it's a beast of an amp, and if it does what you are looking for, its worth every penny. Hope I have been of some help

Just one, but it has two voice coils, so you can configure it in two different ways (this is dual 4 ohm, so that gives you these options: 2 ohms impedance if wired in parallel, or 8 ohms impedance if wired in series). If you are unsure about that, look at Apine's website for this sub and check the owner's manual for diagrams (or if you are getting this new, it should come with a manual in the box). Ideally, your amplifier would be able to produce about 1000 Watts rms so you can enjoy the most out of it, but to be safe, the amp shouldn't be able to produce much more Watts than the sub can safely handle (again, that's 1000 Watts rms).

You need at smaller amp, this is to much power for you single sub, I got this amp with two vm audio 12 ',3000 watts each one, this amp got enough power to hit very hard my subs, imagine your single sub, will blow out
