I'm actually driving a myvi and still new to audio systems. This is how I configure my 4-channel Caliber 2000W amplifier:-

2 channel to my JBL 12" woofer and 1 channel to my front 4" stock speakers. My
rear speakers (don't know the size) is connected directly to my original myvi
headunit.

My problem is sometimes the amp shut down automaticaly and I've got to wait for bout a min for it to switch on back. What's probably gone wrong ? I'm actually in my uni in perak and if possible, I wanna DIY myself.

Another problem is that I'm not sure weather this should be the good configuration for an audio system. Any suggestion that you sifus can recogmend me ? Was actually thinking of changing to a better 4" speakers, is it worth it ? coz sayang wanna drill a hole at my door panel.

this is a good setup already... you are on the rite track... 4" speaker are best at vocals... get a 4" component then the sound staging will be lovely for the vocals... but if you wan more mid bass then no idea but to use a 6" mid bass...

bout your amp... i think it is over-heating... have you check whether it is hot when it shuts down? if it is... try to lower the gains for every channel... if the problem still presist then should get an independent amp for the sub...

hope this helps...

cheers...

over heat bah
try to see whether the protection light is on during the shut down period

seems like amp overheat

Lowered my gain ... So far seems to be alright.

About my configuration , should I disconnect my rear speakers from my headunit ? I've got a feeling that the sound comming out from my front speakers(amplified) and my rear(not amplified) are different and it sounds kinda weird.

btw, wuts the difference between 2ways speakers and 3ways speakers ? Any suggestion on what types of 4 inch speakers should I get for my ride ?

the speaker you mention is component speaker or coaxial? component are consist of one pair of midbass(5"-6") or one midrange(3"-4") or even both of these, passive crossover and a tweeter... each speaker is separated from each other... while coaxial are those speaker that comes in one... one big cone and on top there is those tiny tweeters... usually component are for front fill while coaxial are for the rear fill...
IMHO... component sound will win coaxial sound hands down anyday, anytime... provide they are compared from the same range of product...

the sound that are connected to the amplifier will sure sound good as more power are feed onto it and the amp are able to control to cone more effieciently... thats why it produces more details of the song... using an amp to power a speaker will also minimize the possibility of sound clipping...

while our HU which built-in amp are jus 17W to 20W RMS... when you play your music loud... you will get distortion and most of the time, the amp is clipping... so you will hear that the sound weird...

IMHO... you can leave the rear speaker connected to the HU... but if it is interfering with your sound-staging then unplug it...

cheers...

amps are easily get hot especially when you bridge the channels to drive subs

Yea ... I think it got over heated. It usually shut down whenever I switch it on loud for a couple of min and then lower it.

Btw , I'm actually using a pair of stock speakers for my front and my rear. My front are normal 4" component speakers I think , and my rear , I'm not so sure bout it (never open it before). Actually added a 120W pioneer tweeter to the front. Now I'm actually planing to change the front 4" speakers. Any suggestion ?

I might change the tweeters also , don't sound nice to me.

Btw , I also would like to thank you all for sharing with me your experiance

if you wan to change the tweeter and the 4"... then my suggestion would be change it to a component set... and power them with your amp...

Myvi front speakers are 4"? Damn.... that must be hard to look for component set if you want to use original location.

BMBoschmann RV4200XT... care to try?

can mount 5.5 inch mids at the OEM location
but fibre the door panel for a 6.5 inch mid isn't a tough job

Oh...myvi front can fit 5.5inch?

But l wonder, the original myvi HU (25wx4) can drive component set or not.

if entry level component sure can la... it needs around 5W RMS to drive one... but not to its fullest potential only ma... so the best thing is still getting an amp... if on tight budget... a jalan pasar one will do already...

Actually can, but the result wont satisfy you.

I still suggest that you get a power amp to power your comps. If you power it direct from the HU, the treble and the mid will be 'overshined' by your subs.

Actually getting another sub is not a problem. the problem is the original Hu dont have any RCA. Now power a sub already have to use a high and low filter. haiz....


l know this would lead to a question "Why dont change a better HU?". Well, last few months my kancil have been broke into by thief. kanasai....they not only stole my HU but smash my window somemore in daytime (while l,m working).

go and find one AudioControl LC6... its a 6 channel hi input to RCA converter... not cheap though but its the best currently in town... you can set the gain for each channel... megashine in miri got sell this... but i didnt bother to get the price as i dun need it...

cheers...

Oh....if you know the price pls post it here ok? Thanks.

will try to get the price if i got go back there... you from miri or kuching?

l,m from Kuching. But if u let me know the price, at least l woundn't kena...."sembelit" by the shop. lol
