It's an frequently told taboo that all equipments needs to be from the same brand in order to get best pairing and performance. Been there and done that and all I can say is that...its utter nonsense....

Between the Hertz and GM, I'd pick the GM.

Understood. Btw, I have 1 more question. If another shops wants to sell their HSK 130 (Hi Energy 5.25" component speakers) and HCX 130 (Hi Energy 5.25 co-axial speakers) at the same price of ESK 165 (Energy 6.5" component speakers) and HCX 130 (Energy 6.5 co-axial speakers) because that other shops wants to clear their old stocks, should I grab it? That other shop os also trustworthy seller, plus 1 year warranty will be given, just like other products.

Choose the shop that offers you professional installation work.

The quality of the installation work weighs as evenly as the quality of the product itself.

Guys just ask some review opinion, my car is myvi recently just changed the head unit player and 4 speakers set total cost is rm1900 plus installation etc. for info front speaker is 4 inch size position on the left and right side of the dashboard, and rear side door speaker is 6inch. below is the breakdown :

head unit player entry level
Kenwood DDX417BT = rm900
http://www.kenwood.com/my/car/visual_navigation/ddx417bt/

Front speaker 4 inch (30watts rms)
Rockford Fosgate R14X2 = RM380
http://www.rockfordfosgate.com/products/details/r14x2

read door panel speaker 6inch (65watts rms)
Kenwood KFC-M614P = RM500
http://www.kenwoodcaraudio.co.nz/product/k...onent-speakers/

Plus installation all rm1900 total. what do u think will kena cut throat price?

All the sound i tune myself, crossover frequency front and rear setting, slope,  fader etc all. The HU is not bad have 13 EQ band for me to adjust (62Hz - 16Khz), my personal fav EQ setting is the W shape wave pattern.
And to be honest no matter how i set the bass still very lost, only have tuk tuk tuk sound not boom boom boom, but mid and tweeter so far good kick and snare all clear, only a thing slightly matter which is mid bass is kinda low, vocal bass not enough to vibrate my jeans to feel it (i think i'm too much of a bass maniac person). SQ and SQL consider good only thing missing is SPL! i don't think add an amp just to push these x4 speakers will boost the bass any how because it's not their job to vibrate the car and not their job to pump low frequency. i guess need to add subwoofer already. my only choice is underseat sub because don't wanna use boot space. will try to add 1 underseat active sub below passenger side, if not enough will add 2nd sub under driver seat. oh yeah my music is hardstyle and hard trance, formerly club/disco dj back in 2000, i guess my ears is very sensitive towards sound satisfaction.

UNless u add 6x9 speakers on the rear panel loh.. add 2 channel amp

Yeah bro, i just added 1 active under seat subwoofer but the bass is still very not nice no matter how i tweak the frequency at the crossover. I think underseat subwoofer no matter how can't perform the good low soft punch bass compare with ported box subwoofer (behind boot those). i think is because due to the body itself and sealed type makes the bass reflex so irritating. So far this is the best of tweak can get to match play all genre song, i set the crossover to 60Hz now and slope is -24db (straight chop down line). If set to 50Hz or below the low frequency punch is missing (too low), if set to 80Hz or above and no matter what slope the drum or piano bass vibrate echoing too loud makes it irritating. For my setting here 60Hz the best for mix balance all genre music. Summary is no matter what still those back boot passive box subwoofer plays the BEST soft low frequency loud non irritating BIG vibration punch, those vibration which shake your chest u know what i mean. 12 inch the best to punch out soft deep low frequency bass.

Underneath subs can go well if you intend to play more rock songs actually.. i was impressed.. maybe an sq setup for you would be good tho..

Honesty, seriously i regret bro underseat sub, especially im trance and edm kaki that active sub was just good at playing the trance mid bass 100Hz range note only, totally missing the 40Hz low bass note range which trance bass basically all stay around that range to comfort ears.... after this lesson next year im gonna aim for one biji 12" very very good powerful driver with a good powerful mono amp.

Whats ur budget thoo

max max around 2k budget (mono amp + 1 x 12" sub) actually thought of 2 x 10 inch sub driver but 12 inch can hit better lower note which 10 inch can't achieve plus very waste boot space for compact car.

While i was surfing the net to get some info on which brands to choose for my car ICE since i am still a noob. I realised that there are too many different brands to choose from and dont know how each brand would deliver. I m sure many of us here face this prob. I know some say that u hv to test n c which 1 u like or suits u best. I agree with this statement as well. But dont u think it will be almost impossible to actually test each brand.

So, i found a list of brands that fall under 4 different categories. How far its true, i really dont know. Plus, i belif the people from this forum are not from Malaysia. So, their opinions might be different than ours since the products they get there could be different that what er get here. Correct me if i m wrong. So, i hope all of us here could use this as a guideline only. We would also love to hear your experiences using certain brands. Some brands mentioned here may not be available here. N some brands may have been missed out. I'll keep updating the list based on your experiences. So, tell me which category does the brand fall in.

Ok. Before i start, let me remind u that this is not based on my own research. I found it on the net.

So, the 4 categories are:

Horrible brands - avoid these brands at all cost, they are a total waste of money.

Entry level brands - good for the first time car audio enthusiasts, you get a great sound for a cheap price.

High quality brands - these are more expensive than entry level, but not ridiculously expensive, since you get execellent sound that will be louder/cleaner than entry level brands.

Competition brands - these brands are the mother of all brands, prices are very expensive but if you can afford it, these are the brands that win sound competitions at car shows.
