Hey there peeps, im new to this forum and hopefully you guys can help me out.

So the set up i've got is: clarion 6" and splits at the front, JBL 6"x9" in the rear shelf and a kicker 12" sub and amp WITH an eonon touch screen i know i know but it is actually good apart from the sound quality. My system was thumping before i had it put in, i previously had just a basic pioneer HU but sounded awesome.
What options do i have to get better and more powerful sound? I was thinking hooking up my speaker to a good 4 channel amp? Any suggestions without replacing the HU?

[~Spyne~]

get a 4ch amp and power the front splits and rear 6x9s from it.
set a high-pass filter on both of around 80Hz. Make sure the phase of the sub is matching the phase of both front a rear speakers (if one if out of phase with the others, you will get cancellation and greatly reduced sub/mid-bass)
make sure the sub has a low-pass filter around 70-100Hz.

Ensure the front and rear speakers are solidly mounted - this mean for the 6x9s to put them in some form of enclosure (ideally) and have them screwed/bolted down.
for the front speakers it means making sure the midwoofer is mounted to a nice solid baffle, with no airleaks around it. try to completely separate the front wave from the back wave. sound deaden your doors and seal over the service holes.

there's a start

Very professional, spyne

[Gobbledok]

step 1 is get rid of that eonon double din noise generator.
step 2 is read Simon's article about sq here.
step 3 is experiment, experiment and experiment.

oh and dont forget to ask as many questions as you need to.

[HEKYEH]

There are a whole heap of options to improve the sound quality of your setup, some of which ~Spyne~ covered.

That article by Simon is a really good one to give u a better understanding of the elements of sound quality.

How much do you want to spend? All comes down to budget...

[faze0ne]

Thanks Spyne sounds convincing but how do i actually set it to high pass/low pass on the filter?? HEKYEH i don't really have a budget something affordable of course not ridiculously priced but i want just a decent sound similar to what i was getting from the Pioneer...

[faze0ne]

Ohh i see on the amp im guessing... What amp would you guys recommend and how powerful for my set up??

[br85]

By the way, you want expert advice, NOT professional. Trust me, heaps of people who have worked installing for 20 years still don't know much about sound quality and how to achieve it (though there are a few who do). Your best bet is to talk to people who actually know acoustics AND who have implemented that knowledge. (~thematt~ is one such example).

Are any of these considerable:

(Dont think this one is powerful enough)

Would an equalizer be another option or not as good as an amplifier?

[Pulse-R]

I'd look for something at least 75Wx4 at 4 ohms.

[faze0ne]

out of them which would you pick to suit my situation or do you have one that you can suggest to me with a link??

[faze0ne]

If someone would like to answer this for me how many pre-outs am i going to need for a 4 channel amp 2 or 3?? Can i get an adapter for more if need be??

[~Spyne~]

if powering 2 speakers (front, for example) then you need 1pr of pre-outs (run the amp in bridged/2ch mode)
if powering 4 speakers (front and rear) then you need 2pr of pre-outs
if powering 2 speakers and a sub, you also need 2pr of pre-outs (ch1&2 for speakers, ch3+4 'bridged' to run sub)

as for amps, it depends on your budget. ryda are reputable for online sales, but most/all of their products do NOT come with australian manufacturer's warranty.
fhrx are also very good for online sales - not as cheap, but great service, good advice, genuine products with Oz warranty, and good shipping
second hand, there are some good amps in the FS section;
phoenix gold zx450, spl dynamics s2604, earthquake ph2200/4, zapco ref360.4, jl 300/4

Hi, have you tried going in to a reputable shop to ask their help. Most reputable shops will give you an honest opinion (it is their best interest)

I agree with BR85 there are some people out there who have been around for ever yet still struggle with some concepts of audio. But don't rely entirely on the internet as some people on the web still have no idea....Yet they talk like they do.....

That HU you have was built to have all the connections but SQ was the last thing they were thinking about.... The Pioneer, Alpine, Eclipse etc are still made to sound good as well as having great connectivity....

I would start with a good head-unit then get an amp if you think you need it.....

[faze0ne]

Is it recommended that i get an 8 gauge wiring kit for the 4 channel amp?? 4 gauge wont be enough...
