Ok guys i got this amp for free off my brother and by the looks of it and what he told me its a monster. Now my questions are how should this be wired with my 2 12 inch mtx 4500 subs. Everywhere i look says the gt 24 is 2 channel but when i look on the back it says mono. And how do i and how should i tune this bad boy to compliment my subs. If i blow them oh well thats why they invented better subs for. The whole car is going to get my system installed friday night we have 100 sq ft of fat mat to install and a 2.5 farad campacitor , my subs, and the amp. let me kno what u guys think please.ALSO CAN SOMEONE TELL ME THE SPECS ON THIS AMP. I think its insane for free.

06CobaltssOrange

Please guys give me a little help here
How should this hit the subs?
Where exactly and how shall i tune it?
Waht do u guys think of it?

Lets see.... it looks like its a 900w amp, and i actually have those subs in my car too.. if its a mono amplifier then i dont think u can run both subs, can you? (someone plz confirm this). I have a 1000w Sony XPlod amp powering my subs and they hit HARD.. like insane HARD... cant go wrong with MTX. and i dont really know about that amp, so i really cant tell ya much....

here are some pics of my setup as of right now...
the amp is mounted upside down for easy access to the wiring, btw.

i will not run a sony amp sorry my bro told me he paid a lot a lot of money. he bought it 2 1/2 years ago

Co|3aLt $$

well it's definately a "900w mono" amp, due to the sticker on that boy.. lol. and unless there are hook ups for more than one sub you're limited to one sub. So you'll either need a two channel amp, or another for the other sub.

06CobaltssOrange

well i kno u casn have more then one sub running from a mono block but everywhere i read about a gt-24 it says its a 2 channel i just dont get it.

Piston_Head

Boston's website says it is a 2-channel amplifier.

http://www.bostonacoustics.com/car/c...product_id=247

So you can either hook it up as a 2-channel or bridge it and run it mono.

If you run it mono, you can still run multiple subs. It all depends on your subs. Are they single 4ohm subs or dual?

its a 4 ohm no matter what this amp should run my subs without a problem right do u actually think the amp is a overkill i kno boston acoustics is high quality. Here are the specs im running two
Subwoofer Size 12"
Dual Voice Coil Yes
Impedance Dual 4 ohms
Peak Power Handling 450 watts
RMS Power Handling 225 watts
Woofer Surround Foam
Woofer Composition Aluminum Polypropylene
Sealed Box Volume N/A
Ported Box Volume N/A
Sensitivity 93 dB
Frequency Response 30 - 150k Hz
Xmax (millimeters) N/A
Top Mount Depth 5.5"
Cutout Diameter N/A
Warranty 1-year Sonic Electronix

Piston_Head

Well, the MTX T-4512 subs are rated to handle 225 watts RMS each. You wire them in stereo and that amp is rated at 120 watts per channel.

Run the amp in mono or "dual-mono" as the site says and the amp is rated at 750watts (one channel @ 2ohm). Sure seems like a big jump to me. The site doesn't say if it rates the amp in RMS or max power. I'm guessing max power, but I could be wrong.

I personally wouldn't have an issue running those subs wired mono myself.

If your worried about it, just go easy on the throttle !!

Sorry, just saw your new post.

Since they are dual voice coil, run them in stereo with each sub wired at 2ohm's. Then they will be getting 200 watts a piece. (according to the site)

I gotta run, I'll check back later and see if you got things sorted out.

Check out Rockford Fosgate's website for the wiring wizard if you are having trouble figuring out the resistance.

what the hell.... take a pic of the speaker connections and the fuses for me...

do you have the flash on your camera on? because its hard as hell to see....

ya i was trying to see what the actual words were on the connections to determine if its a mono or 2 chan amp. Doesnt really matter what the web says its important what it actually is

Heres what I can find about it

With a 12.6v input (Basic Car Battery)
4 ohm ~ 120 Watts x 2
2 ohm ~ 200 Watts x 2

4 ohm ~ 440 watts Mono
2 ohm ~ 750 watts Mono

With a 14v Input
4 ohm ~ 175 watts x 2
2 ohm ~ 275 watts x 2

4 ohm ~ 550 watts mono
2 ohm ~ 900 Watts mono

Look at the pictures guys...


Right Smack dab in the middle on the bottom there is a positive and negative terminal, and a 2nd positive and negative terminal. TWO CHANNELS!

If you said your subs were both 4 ohm impendancy, you want to run your subs in Series and bridged. This would show the amp as a 8ohm impendancy and be around 220watts.

06CobaltssOrange

wow so in fact its two channel do u think it will hit theese two mtxs immensly

I think they will thump pretty good. Depending on the box and what the box is tuned at... they could get pretty loud.

halfj99

a single channel amp can run more then one sub just gotta wire it in series

Switt23

... or parrelel. It doesn't matter either way they "Could" work. It depends on what impendancy your trying to get. Series Adds the ohms, parallel divides the ohm by the number of subs granted they are all the same rating.

Series. Two subs both with 2ohm = 4 ohm load

Parrelel. Two subs both with 2 ohm = 1 ohm load

How a lot of people pop their amps. Don't really know what they are doing and wire down to a 1 ohm load and their amps aren't stable at one ohm.

cobaltguy88

I never said you had to, im just showing u what i had... geez..

Not true, these subs can actually max out at 500watts a piece... I have my sony 1000watt amp pushing 2 of these bad boyz perfectly.... how do i know? my friend jake who owns an Audio Express here in Phx, AZ told me that MTX themself mailed his shop a guide to the Thunder series subwoofers.

As is usually the case with most car audio there is lots of mis-information around. Thanks in no small part to misleading advertising.

I'll try and make this post as cut and dry as possible, for your sake. Otherwise it will make you crazy.

You posted that you have two 12" MTX 4500 dual voice coil subs. They are rated at 225w RMS each. RMS power is all that matters. You can send 500 or 1000 watts to each sub if you want, just depends how long you want them to last. You can give a sub more then it's RMS power, as long as it is clean and you will be fine for a daily driver, within reason.

Here are your subs specs direct from the manufacturer.
http://www.mtx.com/caraudio/products...hunder4500.cfm

All your amplifiers specs are in the original link I posted. Here it is again, direct from the manufacturers site. Click on the "quick specs" link for the actual numbers. For the sake of this post I will assume that Boston is using RMS power for it's ratings. (hopefully)

Now on to the wiring .......

Here are all the different ways you COULD wire your subs.

To wire them @ 1 ohm MONO.(which your amp does NOT support)



To wire them @ 4 ohm MONO (which your amp supports @ 1x440w)



To wire them in two channel or stereo, each sub is wired to each channel separately. For 2 ohm STEREO (which your amp supports @ 2x200w), wire each sub as follows.



And finally you could wire the amp in 2 channel @ 8 ohm's, but your amps power would be way down, so there is no point. BUT to show you how to wire it here you go.



So you can either wire it like the 2nd or 3rd picture to get the best match.

To wire it in 2 channel or mono, just follow the markings on the amp. It shows positive and negative for each channel and it shows which speaker outputs to use for mono if that is what you choose.

Hope that clears it up a bit ...... Who knows, maybe I made it worse !!!

Not to be a downer here but since I have heard so much about this XPLOD amp I had to pipe up and say something, The Sony sell the amp for so cheap because in reality the amp won't put that kinda wattage out. Its like the old cheater amps in reverse. I have seen a few of those bench tested and the highest one I have ever seen was 440w and that was right out the box. In the end YOU GET WHAT YOU PAY FOR. Don't get me wrong 400-500 watts is stiil decent power to be running into 2 12's I'm sure it sounds great but if it was really 1000w that 8 gauge wire you have running to it wouldn't make the grade. BTW taping your RCA's to your power wire might cause you problems, rule of thumb is to keep power wires and signal wires (RCA's) 12-24 inches apart
That Boston amp however is the real deal, you got a good score (I wish my brother gave me such nice things) But as was already stated hooking it up to 2 DVC subs is going to be tricky since the amp is not 1 ohm stable
Thats your best bet right there. Its going pound real nice just be sure not to go cheap on the wires. You can have the most expensive/powerful system out there but with the wrong wires it's going to sound like s**t.

are they the 4 ohm singles or doubles? if they are the dvc then wire them 4 ohm mono... if svc then wire them to 8 ohm mono

cobaltguy88

I havent had any problems with this amplifier whatsoever... Iv had it for over a yr now and its STILL crankin out some nice power... I love sony products (my cousin whos in Iraq right now actually had Sony sponsor one of his show cars in california) and have had nothing but great experiences with their stuff....
Its all about personal preference, IMO, one person may like Sony and another might hate it cuz ONE sub blew out or what not.. so eh, thats all i have to say about that..

And btw, the wiring was done as it is by choice.. I know its supposed to be seperated but its easier for me to access hehe...

I should put up a new pic of my new Kicker amp, subs, and box... ill post it when i can.

mfcordova2007

I don't know alot about connections and that but i also have a mono block and u connect it as u would any other amp + and -. i'll put some pictures of what's in my car.
