You are not going to get hard chest vibrating lows from any speaker in that size range. Ading a subwoofer with those speakers will make your setup complete. Then you will hear the Big BOOm....

I always recommend sticking with the same manufacturer for all your speakers. Mixing and matching (unless for very good reasons) can sometimes lead to problems..

Differnt speakers & Different subs doesnt matter. Its actually better to buy separate because you can use what ever you think sounds better. I have two carvin passive speakers and i have two JBL Mpro 418s subwoofers. Not all subwoofers sound good. Any subwwofer or any speaker will be hooked up the same as any other brand.. From amp to the speakers.

I beg to differ.. especially with active speakers (mainly because most active speaker users dont use outboard processors and crossovers)

With the correct crossover settings, EQ & amplifier gain, its actually easier to match different speakers with a passive system..
I've seen a lot of guys mess it up though..
so.. let me clairify
For DJ's who have never EQ'ed and matched a sound system, and just simply "plug an amp into a speaker" their best bet is too purchase their tops and subs from the same series and manufacturer. (in my opinion)

There is a lot of good advice here. Let me see if I can add to the mix. I've been at this for decades and have made about every mistake possible. Hopefully I can help you avoid the pitfalls without boring you with numbers.
Somebody mentioned earlier that you should be looking at RMS wattage. As you're starting out that is a good suggestion. The peak wattage is what you will get under perfect conditions right before you kill your speaker. If they don't give you RMS wattage assume they are talking peak. Usually RMS is half the peak number.
Your amp should be 1.5 - 2 times the power of your speaker. The reason behind this is that when you turn your amp all the way up, you are usually sending distortion through your speakers and this will blow them quicker than overpowering them. If you think you can't control yourself think about getting a limiter also.
Since you are on a tight budget, you will probably need to buy something used. Don't be afraid of using powered speakers. For a beginning DJ they are a good option. I would not suggest them for subs though. Unless they are wood cabinets (most aren't) the bass won't be the same.
B-52 makes a good inexpensive sub. I am not thrilled with their tops but I am probably too particular about my sound. If you are planning to play a lot of music with deep bass (like rap), you will probably want to go with 18" woofers.
If you want me to bore you with the details, I'll be more than happy to tell you why one is better than the next. I hope this is enough to get your started.

Speakers tops that are active have eq settings. Any brand active subwoofer has a built in crossover so you can adjust it . If you dont have active subwoofers because its passive, you buy a amp and a crossover. Whats not to match of that. Its not rocket science. There are some djs that dont know anything about hooking up equipment. What if they dont know how to hook up speakers tops and subs of the same brand.. Same thing right ? so how does different tops and subs make a difference. If you want your setup to match the same logo and be very picky about looks, then you get the same. I don't really care about same logo. I just want the best of tops and best of subwoofers.
Any subwoofer will do. It doesnt matter the brand because when they are active, they have a frequency setting and a volume. The bass will blend in easy with the tops. If you dont know what you are doing, it doesnt make the fact that unmatching brands is bad. If it was an issue for un matching, then it would be a problem for passive speakers because you have many amps to choose from. Example.. Yamaha Passive speakers and QSC amp.

OK, bass bottoms, bottoms, subs, etc. It's all the same. Bass bottom is just the old school term for it. I too suggest that you get 8 ohm subs (this only applies for passive). A 4 ohm load will limit you to only using expensive amps if you want to use 2 speakers per channel. The extra power you MAY get from using a 4 ohm speaker can easily be offset by buying an efficient 8 ohm speaker. This is what I was talking about previously. The true thing that determines your loudness is the SPL. A 350 watt speaker with an SPL of 99 db will be half as loud as a 350 watt speaker with an SPL of 102 db. Every 3 db equates to approx. twice the sound.
You will not get pounding bass from those speakers. Here's a trick for you. Get speaker stands and put the speaker horns at ear level (approx 6 feet). This will make it sound a lot louder. Keep your subs on the floor.
As a beginning user it is usually better to buy matched speakers (which usually means buying from the same manufacturer). Later when you learn more about the specs of a speaker you can venture out and match your own. Not all subs are the same. Each manufacturer's speaker has different specs and different frequencies that they are better at. You may buy a good sub but if your tops aren't a good match for those subs, it won't sound good. There's a whole science behind that too but...boring.
For the most part you get what you pay for. You will probably be trying to buy more within a year. I hope everything works out for you. If you need more help from someone who has seen equipment and DJs come and go, feel free to PM me.

There are different ways to hook up subwoofers. I just keep it simple.. I am using two Jbl Mpro 418s subwoofers 600 watts rms & 2400 watts peak. It has a 135 db max spl. The subs are 4 ohms. I am using a QSC plx 3002 amp that pushes 900 watts per channel in 4 ohms regular. I am using a DBX 2/3 way crossover to separate my tops and subs. It sounds really good. My speakers push 400 watts rms in 8ohms so im using a QSC plx 2402. The 2402 pushes 425 watts rms in 8 ohms. I could use another amp that pushes alitlle more watts for the tops but it sounds good enough alrteady.

I wasnt talking about "hook ups".. :-)
I was saying that mixing and matching can add another layer of confusion for newbies. (just understanding RMX VS Program between manu. can be a pain in the arse)
arguement is mute anyways.. with the information you posted about your system, It probably does sound "nice", but could sound "holy crap awesome!",
but the only way to "prove it" would be for you to actually hear what your JBL subs can sound like in a system with properly matched amps and tops. (you didnt post what model of tops your using.. so maybe they are a good match? I do know your underpowering your subs, but again, might be a good match for the tops)

The Hookups part.. I was talking to No doubt..
@ Hippy. The tops are Carvin Pm15. They are 400 watts rms, 800 watts peak. 100db spl. The JBL subwoofer can take alittle more from a more powerful amp more like 1,100 watts rms per channle but 900 watts sounds good. Before i had another qsc plx 2402 for the subs but i sold it to buy the 3002. I was lucky to buy the 3002 for 400 bucks.
The 2402 for the Tops & The 3002 for Subs.

Caliente, don't get me wrong. All of my comments are geared to being sensitive to a newbie with limited funds. Yes it is good to get an powerful amp that runs stable at 4 ohms that matches your speakers specs. But the less expensive option would be to run a less expensive amp in bridge mode for the subs. Using 2 8 ohm subs will also give him the flexibility to not take a large speaker when doing smaller events.
Also like I mentioned, having your amp 1.5 to 2 times your RMS will allow you to push your speakers and still sound clean. It looks like you are doing exactly that. I too love my QSC and Crown amps.
Oh yeah, here is something else a newbie should know. While you can plug up a bunch of speakers into one amp and get sound out of if, DON'T DO IT. You will kill your amp quickly if you go below the manufacturers recomendations (and it will not sound good either). Here's what you need to know...Every speaker has a load (ohm) rating. If you have an connect two 8 ohm cabinets together your load changes to 4 ohms. I know it sounds backwards but that's science for you. I am talking about using 1 channel of an amp and passive speakers. So if you hook up two 4 ohm speakers, you get 2 ohms. There are very few affordable amps that run stable at 2 ohms.

Go to the pawn shop. Get you some big ass Peaveys, the 50 pound ones. Go get a Behringer amp. The Euro series, 800 watt. Get some cables, plug them up and rock on. Go old school. Never look back. Never, ever look back. Tell them frat boys that CRash said "whats up".
