coaxial speakers have the most basic of passives, and the chaepest, which is usually a small capacitor that acts as a simple high pass filter for the tweeter.

if u buy a COMPONENT SET, it will include a passive crossover

if u buy them individually, the passive wont be included.

the type of crossover between amp and hu is called electronic crossover. if u have enough amplifier channels then u wont need a passive crossover. also, some players have inbuilt electronic xovers already.

example, in a 3 way system, u have a pair of tweets, pair of mids and a sub. to play active 3 way u need 6 channels of amps. usually one 4channel amp and one 2ch or monoblock amp for sub.

if u only have a 4ch amp, then u will need a passive xover. the passive goes in between amp and speaker. it divides the sound between the tweeter and the mids. (high range goes to tweet, midrange goes to the mids)

any decent 4 x 50W amp will do

dont worry about the 2ohm 4ohm yet....

the kenko amp is cap ayam la, id suggest u save up some more to get a better amp

ckmoy
thanks for the bump, but me takut his budget not enuff

gilbert
the amp is around 1.1k, can nego bit la...

buffalo soldier,
sell your rear 3way spkr, then add to the 500 budget for your front components. if u already bought a pre-amp, then can sell that as well to increase front speaker budget. your player is ok already no need pre amp. for simple sq system all u need is a 4ch amp, a sub and front comps, thats all, keep it simple..

buffalo
yes, taman dagang every friday nite, lebih kurang 11pm-3am, corner lot (Starwalk Cafe) dekat 7-eleven belakang Galaxy Shopping Center
500 tak dapat le focal, 700 boleh....beli la lepas jual your stuff

gilbert
your price range i got one PPI 4ch amp for RM700, or if u want just 2ch better get the Phoenix Gold M25, RM500 new.

eh i got 2nd hand cleansweep la, mau? hehe....

what is the amp specs? is it the 65W x 2 one?

the sst6.9 im assuming is a 6x9 spkr that u use at the back

and u say the pg45 is a 4 inch speaker? are u installing it in front?

i dont think the 4 inch spkr can be blown by that amp if its only 65W. if u prefer bass, then use it for just the 6x9 spkrs, power the 4" in front with the HU power.

if u want to get into SQ, u can power the 4" spkr with the amp, and use the HU power for the rear 6x9

i dont recommend powering both of them in series bcoz of the 3ohm 6x9

one more thing u can do is use a 2 way passive, but has to be custom made, lowpass and highpass around 300hz and suitable for 3ohm. this way, the 6x9 will play bass only, the 4inch will play all the mids and treble

u can buy 2 sets of components, for front and back. usually i dont recommend speakers for the rear, but your car is large, so its ok la..



good amp will have good power (clear and controlled) will make the speakers and subs perform well. sub enclosure have to follow manufacturer's recommendations. yes size and build quality matters, so make sure theyre up to specs. u dont need a capacitor, youre not running a high power system, plus your alternator is strong enuff already. yes id recommend a 12 inch sub too.

id recommend getting a 4ch amp for the 2 sets of components, and a 12 inch sub, with a suitable 2ch or mono amp. for HU pls get a decent cd player with 3 rca outputs.

the 3ohm is ok since its connected independantly on its own channel.

yes there should be a fuse for your power cable close to the battery.

and yes monster cable is an ok brand, can also use stinger or steeetwire or audison. aura also can la if strict budget...

yeah can also, look for component speaker set, around 700-1000 can get an ok one already, for beginner standard is good la, but since u will be running without amp, try to find one that doesnt require a lot of power, maybe something 50-80W RMS

i have helix esprit component set RM900, and focal access components rm750

if u want 1k for amp and comps is possible but u end up with cap ayam stuff.

if u can go to 1.2k, i can offer u Phoenix Gold M25 amp and Focal Access components.

for 1k i can offer u 2nd hand peerless component set and a new phoenix gold m25 amp

a good SQ system can at least reproduce the whole audio frequency (20hz-20khz) with ease and with certain qualities. havent even got into good staging, imaging and tonal quality.

and its actually called an active sub, not passive. active bcoz the amp is inbuilt into the sub enclosure.

if an 8 inch active sub can achieve good SQ then id be dancing in the street, naked in the rain....

jimmy dont get too worried about class, just must know the amp good or not first. so just shop around and see what amp u can get that gives you 300W rms @ 2ohm. come back here and list what amps u found within the budget, then we recommend which one to get.

bukanmain yes u can upgrade step by step with HU first. after that i suggest get the front component speaker set first, and then amp and subwoofer.

can get u Helix Esprit component set

not sure la, can be anywhere from 1k to 1.5k depending on shop...

try to join the penang sq tt, then u can learn from them a lot more than what u can read online.

join the autoworld forum ice section i think theres a thread for penang icers, or u can start a thread of your own and u can call for a tt yourself.

cap ayam......

save up bit more money make your purchase worthwhile and long term....

http://forum.lowyat.net/index.php?act=ST&f...0#entry24615781

rogers is UK brand but made in china, as usual china very clever use name of home audio company that dont have any car audio..........anyway its sq is so-so only....

u cant have a sq setup without a sub, the active sub for under seat is only good for midbass only, not sub bass, plus it sounds pretty bad.
