Wiring 4 MTX Thunder 8000 Woofers?

Alright guys, I know some of you out there know your stuff so here goes: I am going to be putting 4 MTX Thunder 8000 12" woofers in my Extended cab s-10 xtreme.  What I need to know is if I hook all 4 up in parallel, the amp will see a one ohm load right? Well, if I hook all of them up in series, they will sound like crap because the amp will now see like a 16ohm load or something like that.  My question is, should I hook up all 4 together but the middle two in series and the outer two in parallel? IS that even possible? I want my amp to see a 2ohm load because I want it to last a while. PLus I still have the option on which amp to buy so I was thinkin a mono block amp from MTX also to power these mad boys. D Class maybe??  What amp (From MTX) do you guys think would be best and how should I wire these??  THANKS

Should I just get two amps and use one mono amp per parallel pair of speakers? I KNOW someone has to know the answer to my question. Anyone??

You could wire a pair of subs in parallel and then both pairs together in series then you will get 4 Ohms (Assuming each woofer is 4 Ohms.) Or get a 1 Ohm stable Amp. From my personal experience I'd try Memphis they make 1000D amplifiers that hanlde 1 Ohm without a sweat, sound awsome, small size, and don't heat up, plus the price is very reasonalbe for a true 1000 Watts RMS amp. Let me know if this helped any.

You have a couple of options.  When hooking up 4 4-ohm SVC subs you can either get a single 1-ohm load or a single 4-ohm load. (Check out these diagrams for more info).

Most regular two-channel amps will put out their maximum power with a 4-ohm bridged load.  The Thunder 942 is probably the most powerful 2-channel MTX amp available right now.  Crutchfield says 942 watts RMS @ 4 ohms, but the manual says that that's "dynamic power @ 14.4 volts".  It claims the "continuous power at 12.5 volts" is 700 watts x 4ohms  bridged .  So either 235.5 watts per sub or 175 watts per sub.

Now MTX also makes the 1501D, which can put out 500 watts x1 @ 4 ohms, 1000 watts x1 @ 2ohms  (both ratings are RMS power @12.5V);  or the dynamic power@ 14.4V ratings are 750 watts x1@ 4 ohms or 1500 wattsx1@ 2 ohms.  This amp seems appealing but it's not even 1 ohm stable so you'd never be able to maximize its power output.  As a side note, does anyone know why the diagram they show in the manual shows two pairs of speaker outputs on the amp, even though all the ratings are given "x1 channel".  Class D 2-channel amp?  Or just multiple speaker outputs for easier wiring or something?

Anyways, with those 4 subs your best bet in my opinion, assuming you want to stick with just MTX equipment, is to get the 942.

If you're open to other amps then there's plenty of possibilities out there....JBL BP1200.1 (1200 watts RMS @1 ohm, 1 and 2 ohm stable) or their new sub amp; or the Audiobahn A18001DQ (1-ohm stable; 1800 watts RMS@1ohm).

The JBL will be probably at least 1/2 the price of the audiobhan if you get it off ebay.   I know you seemed to express an interest in MTX stuff but I just want to let you know of all your available options....

the 942 will put out a realistic 1000W @ 4ohm mono...the 942 is basically an old 2300 with some upgraded components...I have 3 2300s and they are all around 1000W...

sf22 if you bought two 942s, you would need to get four dual 4 ohm subs...that way each sub could be wired at 8 ohm and then the pair could be bridged down to 4 ohm mono thus hitting your amps peak power point...

however, you would need one wicked alternator to handle the current demands of these amps...these amps are class A/B and therefor capable of drawing 80-85A of current apiece, and that is more than most stock alternators are capable of alone, before you factor into the vehicles current draw as well as an amp for your speakers...

the 1501 is a pretty hefty amp as well...but alot more power and being class D its current draw is less than the A/B amps for the same power output...and with the 1501 you could do exactly what I said before with the four dual 4ohm subs...hook each sub up at 8 ohm, and then bridge the each pair to create a 4 ohm load, and then bridge the 2 4 ohm mono setups to get your 2 ohm mono, thereby hitting your amps peak performance at 2 ohm mono...

and esmith, most monoblock amps have 2 sets of speaker terminals like a 2 channel would for ease of wiring...it makes it alot simpler sometimes to have dual speaker outputs from your amp when wiring multiple sub setups...they are not actually separate channels, just a couple of extra points to wire up to make your life less difficult...

and I would second the nomination of the JBL 1200.1...it is a very solid amp and very versatile because it will put out 1200W into 2 or 1 ohm...however, it sounds like you want to stay with one brand for your install (it does look nicer to only have one brand most of the time) so really, you could go whichever way you would like to as far as the 1501D or the 942...

but in any instance, you should be looking very seriously into an alternator upgrade...big power needs alot of current...

Well, I have already thought of the amp draw from my alternator and upgraded to 3g's 160 amp just to be on the safe side. I also have an optima battery for them days where we all like to just sit and listen to music while waiting for whatever we happen to be waiting for. But Big Purds, Thanks a lot with the info man.  I think I am gonna go with the 2 942's and just wire each set of subs parallel to the amp.  Seeing a 2 ohm load won't be a problem for it since I will have 2 amps powering 4 subs. I was thinking about the JBL amp but since I get FAT discounts with MTX.... I gotta save the $ you know?  But all you guys have been great help and I think I am more knowledgable than I was a few days ago about what I was gonna do :) Thanks again!
