n00b to subs

Hey guys, I've been reading this forum for awhile and got inspired to do my own system after seeing a bunch of pictures on these forums (that and my buddy also just put in a sweet system and I need that kind of bass in my own car). That being said, theres something about sub amps that is sort of confusing. When shopping online for a "mono sub amp" many of them have their wattage rated per one channel. can you hook up two subwoofers to one of these "mono sub amps"? example;

on sound domain it says RMS Power: 450W x 1 @ 4 ohms

Bridged RMS Power: 900W x 1 @ 2 ohms. please explain to a n00b! thanks in advance. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 
quick follow up - I havent taken a look at any amps up close, but are there more than one terminal for parallel hookup of more than one subwoofer?

Also, I see a lot of you like Resonant Engineering stuff, but what other brands do you guys like? I'm going to probably go with a 2 sub system, both in sealed (fiberglass) enclosures and I'm thinking the Brutus BX1000. I've heard good things about Phoenix Gold, are they true? I like this new piece (the Octane-R):

edit: picture fixed. sound domain is the greatest, hosts pictures for all the equipment I'm looking at! (expensive store though)

 
The QX has half the wattage rating, 125 and 250. Theres no way you can get a quality sub for 42 dollars anyway, unless you're buying it from someone who "got it after it fell off the truck." How do you think the tantrum-x sub would go in a bigger box though? My sealed enclosure is likely to be closer to 1.5-2.0 cubic feet (for each one).

edit: the octane-R's list for like 65-70 each, so when comparing to others in the price catagory, keep that in mind. I would spend up to like 100 or so a piece, so any other suggestions?

 
oh, another question; sorry if the answers are somewhere in the faq but I didnt see anything quite similiar to what I'm curious of. If I get the BX1000 (or BX 1500 for that matter) would it be better to run two single 4ohm woofers, two double 4ohm woofers, or two 2ohm woofers. thanks!

 
is there really a huge difference in SPL (for the enclosure type I'm considering) between a 10" and a 12". Double coils sounds like the way I'm going to go.

 
single vs dual coil? are the duals much louder?

you're right, if I were doing single coil I would want the higher rating @ 2ohms.

edit: spelling

 
add another question to the mix: if I want to add a multi-channel amp for my full-range speakers, is a crossover really necessary? or can i just use the pre-amp outputs on the multi-channel (or vice versa; on the mono block). thanks!

 
ok, for example, I use this ( http://www.sounddomain.com/sku/PHOR804 ) multi-channel amp to power my full-range speakers. it says: Dual continuously variable 12 dB / octave high- or low-pass crossovers, meaning a high-pass for the full-range guys, I'm guessing? and then it also has pre-amp outputs that I can plug into the mono block.

I'm not even sure the multi-channel will be necessary; I'm gettin the pioneer DVH P7000 head unit that powers 50W per channel. for 300 dollars, I'm not sure I'll even notice the 25W difference in the full-range ones, or will I? Do you think it'd be worth it Jmac?

P.S. thanks for taking the time to answer all my questions by the way.

The reference ho I'm running sounds really good. about .75 - 1 cuft would be about right. mine is in a box barely big enough to mount it 😂
