I cant stay that kind of speed at highway, i'll get sleepy. Unless traffic jam or heavy traffic 90km/h would be alright.

Day: Fly-dei
Date: 21 Nov 2014
Time: 9.00pm onwards

Location: Restoran KINRARA, Sri Petaling (parking here)
GPS Coordinate: 3.070083,101.690922

yeah, i believe that because i got the same result last time.
full tank from KL, driving highway to JB, average speed 90 kmph for 340km and just utilise 3 bars (about 109 km per bar)

btw, to all bros', and long time no see
missed dunno how many N threads

Whole tank is 40litre. Usable 35lit.

Clarion gives good functionality as a stock headunit, output full range signal. The stock 50w x 4 is actually rating for internal amp to almost unable to breath anymore, the actual wattage usually around 22W at 5% THD which means if going down to 1% it will be lower than 22W, squeezing more power gets more distortion, just like asking you to give a speech in a hall without a mic.

Yes you're correct plonk in 8Ohm speaker will get lower power output, it won't strain the amp, just the amp is harder to move that speaker. Car audio usually use the standard 4Ohm is due to the car voltage supply is low, but lots of current so you'll see 4ohm, 2ohm, 1ohm or even go to 0.5ohm for more wattage.

Home speaker and most cheap car speaker weakpoint is the material used will age way faster on bad weather, as you can see most old speaker surround rubber harden and broken.

Alternator when on charging does contribute more noise to vehicle, I agree that. I was suggesting replacing the original head unit to aftermarket headunit as a starting is because the original headunit itself has poor noise rejection on the amplifier section or even the headunit itself generating extra noise to the output. With directly to speaker you won't notice it. But when connect such a signal to an amplifier, it amplify many time more from the source, so you'll hear it. And yes cheapo amp doesn't provide good noise rejection on the hi to low converter.

For my case, adding low ESR capacitor as near as possible to the headunit power supply helps, but only reduce the noise, it still there. Replacing to a better design aftermarket headunit eliminates it, so choose which suits you.

Pure copper cable with good shielding is a must.
Actually, the original car design use car chassis as a main ground, that is why you can see all the electrical grounding are screw to car body, and people claim adding extra cable from battery to chassis and engine to chassis is to reduce the resistance between car body to alternator and battery, so you'll get brighter light, one kick start, etc improvement. Chassis ground isn't lousy as you think, mostly is because bad contact grounding cable cause it.

Don't get mislead by the relay thingy. If you're only use your headunit to turn on the amplifier only, there is no need to add a relay as that signal only turn on the controller in the amplifier, also before the controller there are some noise filter there. Unless you're switching high current application like lightings, fans, custom mechanical parts. Also when using relay, becareful with the relay solenoid current rating, use a small relay will do good as the original headunit control signal are rated 300mA max, pushing beyond will kill the headunit, those headlight relay will drain above 300mA when the solenoid turn on. You also need to becareful on the relay inductive kick back which most of the time you'll hear a tick sound on your sound system when the relay click, sounds annoying and dangerous as the kick back suddenly generate high voltage back to kill your system, remember to install the kick back suppressor, usually a diode or a resistor to tame it.

I wonder huai no pipu pull fat cable to ECU power supply and grounding, adding a capacitor near to the ECU and expect +5hp.

Any reasonable usb HU aftermarket would do the trick? Saw some china brand HU around < 300 bucks. Ok or not? Speakers 2 unit maybe invest in better ones.

wah, mine before 300 already time to isi. too many traffic light launching and cucuking haih..

haha, find some friend to chat in forum ma, inspira forum quite dead now cause mostly move to whatsapp

woah, then it's quite fuel saving, my swift 1.5 4AT, every time pump around 35 liters also, usually 400km or less need to refuel d

Don't cincai invest in china brand HU, some can be worst than original. Better go for Pioneer or Alpine entry level, they do the job well, so really worth it.

Speaker get Mohawk coaxial replace all 4 speakers ok liao or you can find a tweeter pod like this to fit a component set at front. If not into heavy ICE I suggest keep it simple will sound better.

So u come siram this thread to overtake Insapla tered issit?

to makes new fren also la, lol

champion driver/car banyak free

n3w i dont know other shops price, but last time i change for kancil HU i amik kenwood, siap with usb and ipod playing features, also less than 250 bro. pasang kedai abang charge rm30(expensive) but oh well.
now i saw some entry level pioneer kenwood at kedai abang less than 200 dy. u need jalan2 check bro hahaha
go malim brothers, alot choices

You sound like a pro. Anyways, those are only my personal opinion, not necessarily fit all.

Adding capacitor will not alter ECU fuel mapping, however adding resistor to intake MAP sensor will

Running a 1.5 4AT dinosaur, 35lit for 400km in city drive is considerably reasonable fuel save. Try a Kampro 1.3 with 4AT iskazulka For that 35lit on city I think around 220km ady fuel warning dao until wanna picah desbod liao

koreksyen. 35L x 9km/L = 315km
nzh0920 mine average 9km/L in town driving. btw, in town driving i usually pump about 28.69L = rm66.00. when fuel lit up, average gaga fuel got about 8L less. so usually gaga refuel 32L full tank.
9km/L average for light footed, warmest aircond temp settings. could get 220km only for 28.69L full tank IF my gaga set aircond temp to half.

Anyone tried replacing the bulb inside the AC cluster? Found 1 of the bulb fused on my saga.

woot.... 220km, susah to accept, lol

well then, go to corner and suck thumb like the rest (s@ni & Quazacolt)
