I got this amp here:
MTX Car Audio - Archive - RT4340 (http://www.mtx.com/caraudio/archive/rt4340.cfm)

I really would like to do something a lil different this time around. Could just buy a normal passive set like rsd's or whatever but this time I want to buy mids,tweets, and xovers seperate. Not sure on how to go about matching the pieces up with frequencies and all. Need a set of 6.5" with some compatible xovers, and some nice azz tweets to set if off. I could bridge my amp or run a set of each in my four doors. Been looking on Madisound and Partsexpress but not sure on what to look for. I do want some nice loud midrange and decent midbass and once again, some clean smooth tweets. Can someone lead me in the right direction please.

2way or 3 way? If you call parts-express or Madisound they can also help you with selecting the right components for the xovers. A ton of choices as far as tweets and mids go, what's your budget?

Straight Trash. if you gonna run a old mtx get you a blue thunder pro or one of the thunder series like a thunder 302 or something. the road thunders are terrible. i dont care how nice your speakers are they will sound bad on that amp.

Hey there OP. I hope you're having a nice day. I couldn't help but notice that you're interested in buying yourself some new component speakers. I also noticed that your current amplifier has been called less than stellar by another poster. Maybe you should put some thought into purchasing my JL Audio 300/2. It's in pretty decent cosmetic shape, it's in 100% working order and I'd be willing to let it go for a fair price.

Just sayin'....

you need to be careful when selecting speakers and building your own set. read up on Thiele/Small parameters and how to apply them. also pay close attention to speaker impedance, off-axis response, power handling, mounting depth, cone treatments/materials, etc. some speakers are designed for small sealed enclosures (not car doors).

Madisound has some car audio components, that are matched speaker sets. kind of middle ground.

I think Zaph has a nice component set on madisound too.

thanks for the replies guys, ill check Madisound and see what i come up with. Budget is around $200.00 for a complete set.

I like this amp, does its rated power and more. Speakers I previously ran off it sounded pretty nice. What makes it "trash" as u say?

As much as I hate to send you to DIYMA. I would look through the review section on there a lot of old good stuff about drivers from Partsexpress and madisound and others.

I would not waste my time posting there but it is a good place to dig up old reviews and research.

You would probably be better off going active via amplifier crossover, or external electronic crossover if you REALLY wanted to piece together your own components. I say this because it'll just be easier in the long run. Granted, you'll have to use all 4 channels on a 4-channel amp, but I'd say it's worth it if you want to try your hand at something new.

gonna have to do some research but this does sound interesting. Do I need any special h/u or xover to dothis or can my existing gear work?

^agreed, that also saves the cost and hassle with a custom passive crossover.

Your existing amplifier doesn't have a crossover flexible enough to do what you want. However, an external electronic crossover can be had for relatively cheap, or you can buy a headunit that is active capable. But for the sake of price, I would go with an external crossover unless you intended on buying a new headunit/new amplifier anyways.

It does take a lot of reading to really understand what you would be diving into. Before you even think about buying anything, you should spend a few days reading what exactly it means to go "active," and what the pros and cons are.

I have these https://www.madisound.com/store/product_info.php?cPath=45_228_256&products_id=846&osCsid=40a1d5d19e89c4a45d4a010f2ba03953 and for the $$, YOU CAN'T BEAT THEM.

I'm using a set of PG Elite tweets for now, but I'm also looking into these https://www.madisound.com/store/product_info.php?cPath=45_229_324&products_id=1466&osCsid=707c38ae55b73f48501bdb4fd049ce17 or these https://www.madisound.com/store/product_info.php?cPath=45_229_250&products_id=633&osCsid=29844a0be6eb23a26e92fb8f207d5ab0 to replaced them.

All in all, that's $128 plus S&H ~$11, so $140 and enough left over for a decent xover to go active with them.

looks nice man, they sound pretty good i bet. Can u or anyone give me some kind of idea as far a what kind of xover to be looking for?

The only downside to those is that they're 8 ohm mids and not 4 ohms.

I'll have to get a DQX someday, but for now the amp and HU I have can split up the freqs for me to run a 2 way active front end. I already use a DQS.

thanks alot man for takin the time to help me out. I really appreciate it. Im sure i can afford something like that Clarion with no problem. Those are the type of oxvers i use to run back in the day when i first got into this audio stuff. I could still just run my sub off the h/u xover right. No need to run it through the electronic xover is there?

That alone is not a down side, at all. People should really get out of this mind set...

There aren't any Navi/DVD active capable double-din units out that I know of - you would need an external processor. There just isn't a market big enough for manufacturers to make double-din, active capable navi's :crap:

I don't have any personal experience with them, but there was quite a bit of talk when they first came out. If you google "830875," you'll be able to find lots of threads on DIYAudio and DIYMA.

Here's a quick link: site:diymobileaudio.com 830875 - Google Search (http://www.google.com/search?hl=en&q=+site:diymobileaudio.com+830875&sa=X&ei=8QI6TNOGA4bGlQfYp6HVBw&ved=0CDUQrQIwBA)

Sorry, but I don't suffer from that mind set. I used 8 ohm tweets at one point. It's only a 3dB drop power wise, most people want the most they can get from their amp and 4 ohm would do that over the 8 ohm, my bad for assuming that.

Getting the most out of your amp doesn't always mean getting the most amount of power. When comparing 4ohm to 8ohm drivers, it's the efficiency that you need to be mindful of along side the other specs, not power handling or impedance alone.

Obviously, if the 8ohm driver has the same efficiency as a 4ohm driver (and they are the same model), then the 4ohm driver would get louder - you are correct in that aspect. However, the most common scenario is quite the opposite: 8ohm drivers usually are much more efficient, and require much less power for the same SPL. Here's a good read on 8ohm vs. 4ohm speakers (http://www.diymobileaudio.com/forum/diyma-tutorials/31-real-deal-8-ohm-drivers.html).

The mindset that most people are in is that since an amplifier will not provide as much power at 8ohm than it can at 4ohms, then the speakers will not play as loud. That's simply not true; there are other factors that decide it's output.
