Good amp for two 12 ht subs

[Deepair007]

First, would these subs be great for small HT? They were originally for car use. If so, what would be a great amp for these subs? I can control crossover at the reciever (rx1070).

Perhaps try modelling them with winisd or bass box pro etc first.....

I would hit up Parts Express and get a reasonably good plate amplifier, then mount it in my rack.

Ensure that your custom built or upgraded powered subwoofer system performs at its best, and includes every convenient and expected feature, with Subwoofer Plate Amplifiers from Parts Express.

You can also get dedicated subwoofer amps that are external, but they tend to be a bit pricey. But, they have them as well...

If/when you determine the subs have sufficient output for an in-home application, Crown, QSC and Behringer pro amps are also popular for diy subs.

Thanks for the recommendations. At first I was looking at Berhinger nx3000d with 900watts or Crown XLS2502 with 750watts but maybe a plate amp would be good enough for cost.
What's confusing is the fact that amps have a frequency response so I'm assuming it needs to match or go beyond the capabilities of the driver. I assume wattage is the same way in that the amp should output at least the rms value of the drivers.

The thing with subs for cars is generally they only deal with car interiors, don't have to dig very deep nor deal with a large space. Some are suitable, probably most are not. Drivers may have a max input wattage, but not very meaningful on its own. Sensitivity gives you a better idea of the relationship between amp/speaker when it comes to dealing with power (let alone type of box/design being utilized).

Ok. I ran (4) pa subs with a x-max close to your car audio subs specs. Mine were 18" and 240oz magnets, but still "comparable". Look for a pro audio amp that has low pass and hi pass filters. I ran crown cdi 1000 amps. There's a comparable model for less cash. Mine, i could hook up a laptop and do anything i wanted to it. Super underrated units. Oh, by the way.... it was..... steller.

There are some here that are obsessed with measurements, lovin' numbers and all. Sometimes just experiencing not being able to take a breath in your own home theater room means enough.

Do you already have the subs? Are they already in a box or are you building one?
