yup, just use the 700 for the focal access and run it from the HU first. then start saving up for a decent 2ch amp for the focals for next upgrade.

yup, but u risk damaging the amp or the speakers

good SQ systems usually dont even have any rear speakers. if u feel u need to, then powering it up with the HU is the better choice. in good systems, rear passengers will also hear the front components.

for fronts + sub, since rear pre out is used for sub now.

are your 5 inch speakers from a component set, or are they OEM speakers? usually first upgrade would be changing oem speakers to components, then only adding amp and sub. if theyre oem speakers having them powered by the amp could kill it, make sure the gain level is low.

why not get jbl amp to complete the set?

for a 4ch amp to run sub, make sure sub is single voice coil 4ohm, or a dual voice coil 2 ohm wired in series (4ohm load), this is bcoz most 4ch amp are only stable to 4ohm when bridged mono.

can, provided the electronic crossover can cross at frequencies high enough for the tweeter..

for front usually class AB amp. Class D amp usually for subs, since they cant play frequencies more than 200hz.

difference is them is just their design, not which is better than the other.

its not like in school last time, if clever go class A, stupid go class D

efficient only in relation to power, thats being turned into sound instead of heat, thats all. recently there are class d amps that are able to play full range, however that doesnt mean its better sounding than class AB.

quality of amp depends on how it sounds, regardless of its design.

there are 12 pages in this thread and a lot of good advise on what a good starting system for SQ is.

get an electronic crossover la....

yes, the one with speakers is called passive crossover. it divides frequency at speaker wire level, comes between amplifier and speaker

electronic crossover uses rca cables, divides frequency at signal level via rca cables, comes in between head unit and amplifier

Added on June 14, 2009, 11:12 pmhave u tried playing with EQ yet? try and boost some low frequencies before u play with gain. anyway u can increase gain as long as u know where to stop, so u avoid sending clipped signals and damage your sub.

yes, high pass for front speaker amp, low pass to sub amp..

nowadays head units have inbuilt electronic xovers already, so thats another way to go

sell the xover and save up for new HU, just use the hi pass and lo pass filters on the amp

can use stock HU with the alpine 4ch first because it can accept speaker level input, no need to buy hi-lo convertor

just power just the comps first and later the sub.

in car audio, waht u pay is what u get, thats why component set always more expensive than coaxials, and of coz sounds a lot better too.

instead of using amp + coaxials, better use that money just buy component set. add amp when u have budget later on...

components always sound better with amp, so depends on your budget lah...can also install the amp later, run the components direct from HU first.


yes you can, that method is highly recommended actually. some dont even bother with rears, kacau the front soundstage only.

most 4ch amps can accept input from a single rca, theres a switch for it, should be written something like "sum or separate"

the one on the right looks like the one in website, so the left could be a copy..?

cd player, 4ch amp, front components, rear 6x9, kautim....

engineered, best to change your player, dont waste money on cheap EQ

jaya yup, thats good also....

get an amp, the head unit amp is very very small, not enough, especially for the speakers u stated above. and get the passive xover from your friend, look for a 4ch amp to start with, to power the front speakers (mtx+jbl tweet+xover) and the rear 6x9. the underseat woofer has inbuilt amp inside already. once the tweeter is connected to the passive xover the sound will be better..

monoblock is a single channel amp, used usually for subwoofers
u can use either 2ch or monoblock for the sub, all depends on what power is required by the sub and how it is wired, if its single voice coil or double
no pls do not connect the 2ch amp to both your components and sub
your components will not sound better, and either the amp will rosak or your speakers will
if u plan to upgrade to better 4ch amp, u can use the new 4ch amp to power both your front components and your sub. use old 2ch for the rear speakers.
