So I have/getting 4) Mtx 6 x 8`s, 3) 10 inch Mtx sub woofers, 1800 watt boss 5 channel amp, and a 4 channel x 50 watt rms Head unit that I havent decided on yet.
My question is will a 4 channel HU work with 5 speakers and at 50 watts will it be able to push all this?
Aso will all this work together?
And does anyone know the specs about the mtx subs I can`t find anything on the internet about them?

Couple things: Just about any head unit will not make 50W of power. They will do about 18W before severe clipping, about 12W relatively cleanly.

These watt ratings you are throwing around are "WLS" ratings, *When lightning strikes*, meaning absolute MAX and probably not a viable number.

Given that, and given the reality of your goals, you might want to consider, running the front 6x8's bridged off the 5ch's main channels, leaving the rear powered off the head unit. The rear should play -20dB to the front anyway, as the front stage is where you want to detect the sound image of the music.

Cheaper here btw and authorized.

But let's backtrack... what do you actually OWN, and what are you considering buying? Because I think I can find you better products quite frankly!

 

[sinister mob]

First off do a search on Fourthmeal's threads in the Audio/Video section. Then take a look at mine....

I went the route of adding 4 - 6x9 speakers. You want components up front as opposed to replacement speakers. Then you want them powered with a good amp. I don't know a lot about the different brands of amps, but an 1800 Watt amp for $174 just does not sound right. The HU as 4thmeal mentioned will in no way produce anything over 20 watts and provide audible music. Use a good HU that has the functions/accessories you want and let the amps add the juice. I recommend something with front, rear and sub RCA outs so you can fine tune everything. It is a lot of work, but do it once and do it right.

I would get a good 4 channel and a good 2 channel amp. Or a REALLY good 5 channel if you want powered rears. I started with a 4-channel for the fronts and sub and wanted a bit more of rear fill. I then added a 2-channel amp just for the sub and used the 4-channel for the fronts/rears. With that I was able to bring up the rear sound just a bit and add some rear listening for passengers. When it is just me I can move it lass in the rears.

Components in general sound better, especially in the escape. With low mounted speakers in the panels, and a terrible stock angle, you need to bring up some front stage with components IMO.

I ordered the 6x8`s online the other day and I'm waiting for them in the mail(have em), I saw the mtx subs with the the boss amp for 140 on craigslist and was thinking about getting them(don't have), and the head unit i'm still trying to figure out what I want it to have b4 I buy one.(don't have)

Excellent. Well I remember your previous thread dealing with the MTX speakers, and I remember you got a smoking deal. But A: Why did you make another thread about the exact same thing, and B: do you really want a used amp and power hungry subs for $140? I would say the subs alone would be a smart call, but the Boss amp makes about 150-200W of decent sub power, and about 30-40W per channel to the 4ch section. 150-200W is not terrible for a sub setup, but for three MTX subs... I think you should go several levels up. I have a bunch of Credence closeout Lanzar Sabre 12's that would definitely do well with only 150W, but MTX has never been efficient and these 10's are no different. Those subs you see are decent machines, but they are space hungry and would probably do better in a much bigger, possibly ported box. I'll let you decide if that's worth $140, but I can tell you that amp isn't going to do much other than clip too soon, too often.

Head unit-wise, well the sky's the limit of course but I think you chose well overall. I would recommend buying a head unit based off the RCA preouts it has (preferably at least 2 sets out, 3 would be better for future use), and based off what type of signal you plan on playing, like iPod, mp3, etc. All the rest is fluff, pretty much. Remember with Pioneers they have an issue with a fuse inside called a Pico-fuse. It will blow if you "hot-swap" rca's, or mess with the ground of the unit while the head unit is powered. And then you'll have unbearable noise in your system. Solution: Always double-ground a Pioneer unit, and always turn off the power supply to the head unit and system when changing RCA wires around or doing anything with ground.

Well this is the actual setup

it does have a lot of space but I have plenty of fiber board so I was gonna make the box into something similar, I would greatly appreciate it then if you could help me out and tell me exactly what setup I should get (amps, subs, and HU) and yes I will be mostly listening to my Ipod or mp3's through the HU. It doesnt matter what size subs or how many subs I just want some decently loud speakers that also have good clarity and bass, they dont have to a box either, I can build my own. And with the amp I wanna be able to play my subs and my front speakers (possibly rears too if I can afford it). Thank you to everyone who helps me out?

 

[fourthmeal]

Next question: How much trunk are you willing to sacrifice?

 

[Jordan31]

Those subs are older MTX Road Thunder 200 watts rms and 400 watts rms max @ 4 ohm each

 

[snac]

I only want about half my trunk taken up but i can probly make either one or two boxes run along the sides of my trunk. Also I will be listening to all types of music.

Alright. Those MTX subs would be OK, but may be inappropriate as a trio. A pair might be better. You could always sell one of them or keep it around for another project. I'd probably pass on the amp, but the subs might be nice.

I need the T/S specs on the subs to design an appropriate box. I think these subs like ported designs, if I recall. With T/S specs, I can run it through winISD, then make a 3D model of an idea in my head.

You are more than welcome to leaf through my builds, you might see a design you like. Also take a peek at my favorite installer's work, http://www.simplicityinsound.com

I've shown this to another E-C'er, but I still think this is one of the best uses of space while still going big:

 

[fourthmeal]

I think I found them:

[fourthmeal]

OK, if indeed those ARE Road Thunder subs that I have modeled... I would NOT buy them. They are short X-max, very large box (both sealed and ported), extremely poorly designed speakers. IF you had a ton of room, I'd consider them. If you stick them in a box too small...all you will get is a wicked one-note wonder setup.

In short...we can do better.

 

[fourthmeal]

And... here's some awesome options you might want to consider. I look toward Meniscus closeouts regularly, because they are amazing deals at times.

http://meniscusaudio.com/polk-subwoofer-p-825.html

I have modeled a pair of these in only 2.5 cubic feet, tuned to 30hz. Ruler-flat, excellent power handling, and for $50 each you are REALLY doing well here. A pair will get up and play very hard for 10's. Smoke the crap out of those MTX's.

And Meniscus also has 12" versions. They are almost the same price, BUT you will need a bigger box. About 3.5 cubic feet tuned to 28hz would be nice to see.

I need to find you a decent set of amps.

Found these:
Kenwood eXcelon 600W RMS (not MAX!), 2ohms (perfect for those Polks for example)
http://www.caraudioclassifieds.org/foru ... hp?t=44110
$100 obo!

Alpine MRP-M500
http://www.caraudioclassifieds.org/foru ... hp?t=44261
$95 (work a deal on shipping.)

Check this out, work a deal on this guy's TWO Hifionics amps. These are very nice amps!
http://www.caraudioclassifieds.org/foru ... hp?t=44670

Such deals to be had just on that website alone.

alright thanks ill check into these amps and subs, and let you know wat I decide but im looking to spend $300 for subs, amps, and a HU and wat idea did you have for the box? I liked that pic you showed me. and im not gettin those mtx 10`s.

 

[snac]

http://miami.craigslist.org/pbc/ele/1777885796.html
What about these? I can talk him down, this might be a good setup, I just need to make a box.

 

[snac]

Or these? http://miami.craigslist.org/brw/ele/1778117003.html
Im finding a bunch of good deals

 

[fourthmeal]

Those are good deals potentially. If they were stolen ,not so much..

Anyway, I'll have to do some more speaker modeling tomorrow after work for ya. I can say that overall, MTX speakers tend to want large boxes, and get very peaky in anything smaller. So... and mind you I've owned a LOT of speakers including MTX...I don't really recommend them for subs. They make fine amps though, like that 3401 you saw in that first ad.

With these "take it all" deals, you may end up spending a bit more to get what you want, but you can easily sell off the other goods via eBay, or better yet go to places like caraudioclassifieds or similar, and with those custom truck boxes,..go to the enthusiast sites that do those trucks. Gotta go where the money will flow!

 

[snac]

So did you do any speaker modeling for me or come up with any ideas? Its most likely going to be two 12's, a 4 channel amp and a 2 channel amp.

Your late evening is my early afternoon. I'm in Vegas. I plan on drafting up those MTX sub offerings later tonight and see what airspace they need. My guess is it will be a lot. You will probably want a mono amp, and a 4ch amp btw. A 2ch can of course be bridged, but most times when running more than one sub...that's going to be less than 4ohms load and anything less than 4ohm load usually is the realm of a monoblock amp, made for subwoofer duty. 2ohm, and 1ohm being the most common.

To help me, you might want to call those guys selling those boxes, and ask what ohm spec those subs are if they haven't listed it.

Heres all the specs, but ya lets see if this works out, if not I'll find a better setup maybe piece by piece.
