I would like to do a pro audio setup on my doors because i think it would be great for at bonfires and just for the loudness in general. Probably just a mid and tweet in each door for now. So this is a very budget build as these are going into my beater car. So what im not sure about is the crossover part. This is my head unit JVC EXAD KD-AVX1 DVD / CD receiver with 3" LCD screen at Crutchfield.com (http://www.crutchfield.com/p_257KDAVX1/JVC-EXAD-KD-AVX1.html?search=jvc+KDAVX1&osp=jvc+kd-avx1&tp=20217#overview-tab)
So im going to need a 4 channel amp and a passive crossover for each side i believe? I see some of the big spl vehicles with tons of speakers in the doors how do they do the crossovers for those? I guess i just need someone to explain to me how it's done.

Those are the ones i plan on using havent really decided on a tweeter yet and do you mean 2 woofers and one tweeter per door? Is that so i can wire down to 4 ohm?

I run mine active off the HU, but in the wife's ride I use HPF on the HU and FMOD's for LPF. That's to bandpass the mids, AQ supertweeters have a built in cap for HPF....

Unfortunately most PA set ups seem to have NO xovers of any kind, just letting mids and tweets play full range. Tis one reason why PA gets such a bad rap in the ca world...

8 ohms + 8 ohms = 4ohms

get all 8 ohms speakers and tweeters

parts express has that 5k passive crossover for tweeter $5 out those on each tweeter

get a low 2 channel amp to power your tweets, wire both 8 ohm tweeters to run 4ohm

get a mid level powered amp 2 channel for your mids wire both 8 ohm speakers to run 4ohm

most 2 channel amps will run at 2 ohms, if you ever need to add more speakers just drop the ohm load to 2 and you will be alright, for example if you add 2 more 8ohm tweeters it will drop the ohm load to 2 channel.

good luck

It's a cap wired into the RCA line it plugs in like a barrel connection on the RCA. There cheap and easy to use

Only thing I disagree with is that many A/B amps don't like running at 2ohm and will get hot and thermal protect. I prefer to use a 4ch bridged and run 2 8ohm mids per side.

If we're getting into ridiculous generalizations there's no reason for more than 1 subwoofer in a car. Multiple tweeters can work beautifully with the right execution.

I'm sure your right, but you will have absolutely no sound quality. How about PA horns?
BTW a bunch of loud cheap speakers will sound like a large transistor radio.

Just because there are a lot of people doing it does not mean that it is a good idea.

When you're playing "music" around 160db's do you really think SQ is a concern?

I run Selenim PA mids (made by JBL), same ones used in stage monitors for smaller venues. They happen to sound just fine at normal levels and do a good job of keeping up when the time comes...

Since I'm a sound quality guy I'll speak about what I know. There are situations where it's best to have your tweeter and woofer very close together. Some would say this situation is 100% of the time to achieve better clarity. With a factory door placement for the woofer this means using a coaxial speaker or a braxial system, which has a tweeter mounted on a bracket in a specific alignment above the woofer cone.

We know what happens when the sound is all coming from low in the door, generally. The sound is low as well. Staging and imaging suffers. One way to help this problem is to use an imaging tweeter system. This isn't just a second pair of tweeters in parallel with the main tweeters, as that would be a hot mess. With careful selection of the imaging tweeter, proper location and aiming, the right crossover implementation, and by adjusting the levels, the extra tweeters can seamlessly blend in and raise the stage above the dash.

Being receptive to this idea means throwing away the follow-the-herd mentality and putting to bed the rehashed installation technique of splitting the woofer and the tweeter by a couple of feet to get that A-pillar or dash tweeter location.

My mistake, though if you wanted to listen to music SQ would be a concern but I guess that would be my preference and not the OP's. I've heard PA speakers in many venues and do not care for them used musically. Being you system is in a car(?) you may have it balanced better than a stage monitor.

I did this in the STi. I ran coax in the doors with some "upstage" tweets in the sails crossed a 6khz. Was just lovely.

Okay I understand your point but 99% of car audio guys are not doing it in that way. So I'll change my comment to 99% of people who run multiple sets in a vehicle would be better off with one properly setup pair. ;)

A few companies make "upstage" upgrades as you know, just for that purpose. I also think of line arrays in a 2ch set up, numerous tweeters and midranges and they can sound amazing. Not a car environment, but most listening rooms have plenty of reflection issues also.

The ONLY speakers used for live performances are PA, so you've never been to a concert, club, jazz hall, or whatever and enjoyed the sound?

I have NO balance, I have LOUD :laugh: My only concern is tweeters aren't shrilly and mids aren't muddy or gravelly, so I guess it has some balance as it blends together pretty well.

Alright here's my plan for the ultimate budget loud:
Amp:Amazon.com: MB Quart OA800.4 800-Watt 4-Channel Onyx Series Car Audio Amplifier: Car Electronics (http://www.amazon.com/gp/product/B00BQU1444/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A1WRTEG7T8P2CK)

4 tweeters: Amazon.com: Goldwood GT-302/S 1/2" Mylar Dome Tweeter Shielded: Car Electronics (http://www.amazon.com/gp/product/B0002ZPRTM/ref=ox_sc_act_title_3?ie=UTF8&psc=1&smid=A385A0XNQBW8HY)

Im going to try running the mids and tweets for each side on their own channel but i have a feeling it will give the mids not enough power and tweets way to much so i may bridge it to the mids and run the tweets of hu power just depends how they sound on different power levels ill have to try a few different setups.

I have run pa speakers in my car, and prefer to run better sounding drivers.
There are some pa drivers that sound good.
I used B&C 6.5" mids and they sound really good, but the cost is high.
I have also used Beta 8s in my doors and they sound decent for pa driver and are way cheaper.
I bought some pyle drivers and ended up giving them to a friend as they were really nasal and cheap sounding (to me).
Everyone has different ears and standards, and this is just my experience.
I now run Usher 7"ers in my doors and put lots of power to them and they make me happy after lots of sound deadening.

I hope you find what you want for your needs.

That's not completley true, yes some of the cheap stuff probably does but I use the fosgate pro tweets and they sound awesome, before I got them my buddy was trying to talk me out of them, then he heard and was surprised how good they sound. Buy good stuff, setup right, it works. Don't get me wrong I won't be winning any sq comps with it but it's loud and clear.

I wouldn't do those tweeters. Get a pair of AQ supertweeters at the minimum. Those tweets will NOT keep up at all with those mids.

Do NOT overpower the mids or they will sound like ***. Make sure you have them bandpassed. Playing too low will limit power handling and sound bad, playing too high they will sound muddy/distorted.

His budget stuff can sound just fine if set up properly. I've messed with $1 PE horns before, made them sound surprisingly good.

And NO not 999 out of 1000 since I have 3 diff PA set ups that all sound very good and have built several more for others on my team. Maybe 990 out of 1000 then :p:

Yes all speakers ****, that was my point.....

In the end it's not really about the equipment it's about the install and application. Almost anything can sound good it's just about how you use it, which again I'll say that most people using pa gear in cars are not doing it right.

Actually you could make a very good case for that. The inherent inefficiency and distortion, uneven dispersion of sound.... Most of them are messy enough in an anechoic chamber.
