Ok so im about to buy a kicker zx750.1 from my friend. I need to know if theese will hit some 12" mtx 4500 series 225rms a piece subs there 4 ohm heres some of the amp and subs backround. Im new to the system scene so.

Heres One Sub but dont forget i have 2 of them.

yup it will haha

 

someone else please help me out.

 

It's a mono block, so you're going to have to be careful how you wire the subs since there is only 1 channel. But powerwise, you should be able to safely run it at 4-ohms and have plenty of power for the RMS levels. You don't really want to be at the peak power level anyways because that's when you risks burning a VC.

 

what u mean be careful?

 

i honestly wouldnt recommend it. That amp is too big for those subs and at the shop it seems like mtx subs are the ones that usually come back blown.

oh and interms of pure simple wiring anything from a 6 chan to a mono block is exactly the same you just have to know what your doing

 

u wud over power them, and like someone said, its a mono amp. hence the amp is set-up for 1 subwoofer. u'd have to bridge it to connect to both. however...750/2=325 per sub. so u'd have 325 watts running to each sub. rms is 225. i'd be careful. u nvr go by peak power, bc thats what it could hit at any given time. continuously its hitting at rms. go to www.ikesound.com and they have plenty of 2 channel amps. thats what u really need. i have a mono amp bridged for 2 sub woofers. i don't like it though. i mean it pounds, but sometimes it's louder than other times. idk whats up with it. like i'll hit a pot hole, and all of a sudden it'll b loud as ****, then it'll like pound but not as loud. idk. i think the amp is bad. **** audiobahn.

 

mono amps are made for subwoofers. the amount doesnt matter just the wireing and ohm loads. a class d mono amp is the best thing to get for subs because it is the most efficient and taxes the cars electrical less and gives you more power generally. Audiobahn is a shitty company and make shitty products the fact that its a mono amp doesnt effect the fact that a 2 year old could make a better amp.... buy a new amp

oh ya its impossible to bridge a monoblock amp. the definition of "bridging" an amp is combining 2 channels to a single load (one channel produces the negative portion of the sine waves and the other produces the pos) a mono amp only has one channel so it cant be bridged (but i understand what you ment.... you hooked up the subs in parallel)

 

what if i just keep the gain down?

 

it's still running the power to the subs from what i have been told.

 

mmm not really but it depends alot on the HU voltage

 

i know i don't know alot, but anything i say about audio r things i've heard from other people. alot of what i say might b wrong, but it's just so if i am wrong, i can b corrected. it seems though with audio every person who wires systems is right in their own mind. i'm not bashing anyone, its just an observation i've seen. which is why i really don't care to understand everything about audio because one person tells me one thing, then another person tells me another. it gets so confusing.

 

The amp and subs you have chosen are fine. The amp is a bit big if you run 2 ohms and if you start cranking it way the hell up you will blow them rather quickly. But on the flip side buying a smaller amp ( or run this one at 4 ohms) will be just as bad because the subs will then clip once your amp runs over it's RMS rating (and is unable to provide clean power). Wire them in parallel and you'll get a 2 ohm load. The amp is rated for 2 ohms so it "should" run just fine. This all of course goes out the window if you wire it wrong, but seeing the specs I'm assuming that the subs are single voice coil, so honestly you can't wire them wrong.

 

You'll be fine with that amp.. I would recomend to buy a new amp. You could get a X thunder 600xd for under $300 with a warranty. You could even get away by using the 300XD. That the right set up for what you have but in case you end up upgrading in the future, you would then need to buy a bigger amp. But yeah, using a mono amp and trying to get the best sound, I would parralell the subs..

 

if it makes you feel better i work at an audio shop selling and installing all this stuff...

 

Emperor knows what he's doing, I'd listen to him....

I don't see how he can get the amp at 4 ohms (which would be good power for the subs) when he has 2 4ohm subs connecting to a Monoblock amp (thats either 8ohms or 2 ohms) So not a good chioce for your setup....(I personally would not do that unless you plan to upgrade your subs very soon.)

I still have a 4 channel JBL thats perfect for your subs (bridged)...otherwise you want a Mono block AMp rated for about 450-500 RMS @ 2ohm (or 8 ohm) or something at 200-250 RMS each in a 2 channel amp @ 4ohms.
