A few examples of some sound system setups that will sound good and not cost too much money. Although some people might say this is way too much money to spend on car audio, others would say it's the cheapest they'd spend. And this is supposing you are going to install everything yourself which I'd rec. because even though you might not be too experienced with doing so, it's a great learning experience and usually you'll do a better job than the installers at best buy or a local shop. If you do find a good installer thier services aren't cheap at all either.

Now all of these setups I'm going to talk about do not include rear speakers. If you feel the need for rear speakers then by all means get some decent coaxial speakers. The only time I would rec. rear speakers is if you want surround sound for a Video system, or if you are installing a system in a large SUV or Van like a Seqouia or Suburban or something, where the rear passengers would want some more sound. But in most cases the front components powered by a strong amp will be loud enough for the rear passengers too.



*The first setup is for the person who want's the least amount of equipment but the best SQ possible. And to utilize the stock headunit. Let's say with an overall budget of around 1,200 dollars.

Now if you want to use the stock headunit you are going to need to convert the speaker wires into an RCA output. To do this I rec. a line output convertor(LOC). The NE-774V from www.davidnavone.com is a very good LOC. It cost's around 40 bucks shipped. For more info on installing the LOC check out this thread http://www.toyotanation.com/forum/t70831.html

In this setup you will be using the front channels of the LOC to send the signal for the front channels of the amp and the rear channels for the sub amp.

For an amp I'd rec. the DLS A5. It does 85 watts rms X 2 for the front speakers and 300 watts X 1 @4 ohms, 500 watts rms X 1 @ 2 ohms and 700 watts rms x 1 @ 1 ohm for the sub(s)

This amp sells for around 475.00 online. (retail is much higher)

For the front component speakers the Alpine SPX-177R are pretty good for the price 225.00 online. They are actually made by a company called Vifa.

For subs, one of the best SQ subs out there is from Image Dynamics. The IDQ is known as one of the best SQ subs out there. The new IDV.3 has a little better SPL than the IDQ while still retaining good SQ. So for this setup I rec. the ID12V.3D2. Running it at 4ohm will give it 300 watts rms from the sub output on the DLS A5. This sub sells for 160 @ cardomain. If you want to spend more then get two of them. That will send 250 watts rms to each one. Or get two dual 4 ohm ID12's and you'll be sending them 350 watts each. The subs and amp can handle it but if you get the dual 2 ohm subs it will be less strain on the amp and your electrical system.

This brings the total to around 950 with shipping.

A 4 gauge wiring kit sells for around 20 bucks and the RCA wires will add another 20 bucks. So figure 45 bucks all together with speaker wire.

I buy my wiring from www.knukonceptz.com they have a quality product with good prices.

If you feel like you can build your own box then you'll save yourself a good 50-75 bucks. If not then have someone build yourself a custom box. Try to stay away from prefabbed boxes like Q logic, it's better to have a custom box made to the exact specs. rec. for the subs. I have my boxes built by Marv, he is one of the best box builders out there, not the cheapest out there but one of the best. http://community-2.webtv.net/MarvsPlace/MarvsPlace/

With the remaining money you have left spend it on deadening mat. My fav on the market right now is eDead V1.se. It's the thickest stuff available (70 mils) and the best price for how thick it is. See this for more info http://www.toyotanation.com/forum/t64909.html

If you want to use a better LOC there are a few other options available soon. The JL Clean Sweep and the Audiocontrol LC6 These are good if you want to go with an Active setup. Which I will talk more about later.

More setups to come...

This next setup is for the more daring. This is an Active setup using a 2 way component set using a 4 channel amp to power the components AKA Bi-Amping . There is no need for a passive crossover. However you will need either an external electronic crossover, an amp that has the neccesary built in crossovers or in this example, a headunit that has the neccesary crossover points to properly seperate the highs and lows. This setup will be loud and clean and deserves a good loud SQL sub, with plenty of power.

For the headunit, in this situation the Pioneer Premier DEH-P860MP will be used. It sells for around 350 shipped online.

The headunit's crossover will be ran in PRO mode which will separate the Highs, mids, and the sub output.

As for an amp you will want to use one that does around 100 watts rms x 4. More or less depending on what speakers you chose to use.

For speakers, my fav. that I've ever heard is the DLS Iridium components. They won European Loudspeaker of the year. Eddiem67 will vouch for the quality of these things.

The 6.2 set sells for around 500 bucks.

On the amp you will have each channel going to one speaker.

For an amp there's alot of good choices to go with. If you want to go with DLS. The A4 would be a good choice. Not exactly a budget amp, but definitely an awesome SQ amp. Another good SQ amp I like is the Zed Audio Draconia, it does 70 watts rms x 4 @ 4 ohms. Cost around 370 or 450 with the Bur Brown upgrade.

For more good SQ amps look into Arc Audio, Zapco, Audison, TRU.

For the subwoofer end of this system I'd rec. a couple of Subs.
1st the Image Dynamics IDMAX12, HIGHLY regarded SQL sub. Plays very accurately, hit's hard, and gets loud. Retail on one of these badboys is 450. Cardomain is an authorized dealer.

This sub is rated for 1000 watts rms but is a highly efficient sub and can play well at 600 watts rms and up. I'm going to be installing one of these with the DLS A6 amp @ 2 ohms sending it 870 watts rms. The enclosure of choice for this sub is 1.5 cb ft sealed.

Another good sub is the Adire Audio Brahma. Not as efficient as the IDMAX, so you will definitely want to send it more than 1k watts RMS. It's rated for 1600 watts rms, most people run anywhere from 1200 to 1400 watts rms on them. These subs have good SQ but great SPL. The 12" retails for 379.00

Some more good SQL subs to look into- RE XXX and other subs from RE, Ascendant Audio Atlas and Avalanche, Soundsplinter RL-p, Digital Designs, Eclipse TI and Aluminum subs, Elemental Designs.

Most importantly installation and tuning is what is important. You can have the best equipment and it can sound like junk if not properly installed and tuned. Deadening the vehicle with eDead/raammat, etc will make a huge difference in the SQ of your install.

If you use a electronic x-over, does it need to have a bandpass function? So that you can set a high and low cutoff point for the mid, or is not necessary?

In other words can you get by with using a 2 way (lowpass & highpass) electronic x-over? Use the lowpass for the mid and just let it roll off naturally.

Couldn't tell ya man, I'm not too experienced with Active Setups, I just know the basic fundamentals of the setup. Eddiem67 can probably answer that one.

Eclipse 8053 top of the line HU (300.00) from me
Rainbow SLC265.02 6.5 comp set (105.00) average price
MB Quart 4200 4x100 (100.00) on ebay right now MSRP 1200.00
12” Adire Shiva Sub (125.00) new
Box (40.00) average price
Misc Wiring (50.00) average price

Grand Total of 720.00 and you can get a lesser HU too.

Yes most higher end head units will do that for you, ie Eclipse, DLS amps has hi and low pass filter but are limited frequencies. My head unit is by passing my mid woofer at 63Hz/12db slope to 315Hz/18db slope running fully active.

So whats the diff between active Xover and passive Xover? i know one of them is the crossover unit that comes with component speakers. But which one?

So its better to have the HU doing the Xover rather then amp? Since you are running the components off the HU, then I won't need an amp then for my speakers (components wise)?
