of course dual 2ohm.

first of all, can ur player support 5.1? if yes, how many RCA outputs are there? if there's a output for centre then u can install a 5.1 system. can ur HU play active? if u wan us to recommend which comp or amp to get, u gotta tell us ur budget and music preference, too.
btw, i'm selling a set of used Boston Acoustics SL60, pm me if u r interested.

if i'm not wrong, multimedia system and SQ system aren't the same. first of all, SQ is very subjective, like in ur case, u love details and punchy bass, sharp highs and big bass, while some prefer laid back sound and moderate bass... multimedia system has to be set/tuned differently, i dunno wat is needed to be set exactly but somehow SQ settings might not be suitable for DVD system. if budget is not a problem, i suggest u getting a single din alpine DVD player and pair it with the alpine H701 processor. then u can play full active multimedia 5.1 setup. amps and comp u can decide after u decided on ur HU. if u wan to play stricly SQ, i think 5.1 is not the suitable way to go. u are better off with front 2 or 3way active setup with sub. of course dat alpine H701 processor can handle this job too, supporting up to full active front 3way + sub. dats all depending on u la. my point is the alpine proc is very versatile which i think suits ur needs, just have to think u wanna pair with which HU. other similar products are Audison BitOne, JL Audio Clean Sweep and etc.

if u wan to setup like ur diagram, best is for SQ setup. i would still recommend the same thing, alpine single din DVD player paired with alpine H701 processor. u can play full active like dat. perfectly suits ur needs as u can change the setting anytime from inside of ur car. the processor has 4 pair of RCA output. 2 for front comp set (1 for tweet and 1 for midbass), 1 for rear and 1 for sub. this setup shud last u for a long time. bear in mind such a setup will require a few amps as u need 7 channels of amplification. pay more attention and allocate more budget to the front system, the rear can juz get a coaxials and a moderate amp will do.
P/S: a lot of ppl using this processor in ICE competition.

of course u may skip the rear. then u can use a different setup. u can either use the setup i told u or get a single din DVD HU which has a gud built in proc so dat u can play active 2way front + sub.
processor means DSP(digital sound processor), a device that enable u to do time alignment, electronic crossover, equalizer and independent gain for each channel. u can just google for alpine H701 for more info. it's a very flexible processor. this proc connects to the HU via optical or ai-net. if other brands may connect using RCA but i heard dat the sound wasn't dat gud compared using optical. usually a HU with 1 preout onli is a sucky one.

well, both brands r considered leaders in making some of the best hu. so, alpine is not bad either. sony oso gud in making electronics, so as jvc and panasonic, but their ice products r so so onli.

1 channel = 1+ and 1- on the amp. 1 rca output/input(not pair) represent 1ch. rca is low level output and output from amp to speaker is hi lvl output. so if u wan to play like ur diagram, u need a 4ch, a 2ch for rear and a monoblock for sub. or in order to save space, a 5ch and a small 2ch will do. if this is ur 1st time diy, then gud luck.

2 RCA (1 red & 1 white) = 2 channel on the amp output (2 +ve and 2 -ve).
while on mono amp, most of them combine the information on both white and red RCA into 1 output, so there's onli 1 +ve and 1 -ve on the output terminals of most mono amps(same have 2 +ve and 2 -ve depending on the topography of the amp). most 4ch amps, will have 4 inputs (2 red and 2 white RCA), which result in 4 +ve and 4-ve in the output terminals as they dun combine the signal like a mono amp does.

this diagram is ok. dun see anything wrong. as for sub, u gotta match with amp. refer to the 1st page of this thread for wiring examples. dvc and svc doesn't really matter, if ur amp can onli go down to 2ohms, then 2 pcs of svc 4ohms wired to 2 ohm will be the best option. of course, u have to match ther power too, u can't be using a 500w rms @ 2ohm amp to power 2 500wrms subs, rite? cos this way, the subs will be getting onli 250w each.

there's something we call Y-cables, which splits the signal into 2. google for more info.

just get 1 comp set will do, leave the rear for the HU to power. then u will have enuf amplification channels. Y cable split ur signal into 2, how the SQ changes varies in different system.

it's all down to tuning. not sure if any of ur HU mentioned got crossover, u can check their spec. bear in mind, if ur sub is too powerful, u might not enjoy ur setup cos of overwhelming bass dat 'cover' the sound of ur comp. dats why gain matching is important in SQ setup.

the sub will not feel the same in aeroback compared in sedan. but u can alwez remove the rear speakers and there will be 2 holes for the bass to come in, dats wat i did for my car. u can alwez adjust the gain on ur amp to ur liking.

whole set for 3k? maybe if u find some nice 2nd hand stuffs will give a not so shitty sound. 5k will give u a decent system at least.

yes u may use the HU to power the stocks first, no problem with dat. u plan to play SQ or SPL? wat kinda music u listen to? below is a thread quite similar to ur situation.
http://forum.lowyat.net/index.php?showtopic=1185806&hl=

lets say if ur budget is 5k, i'll give u an example setup dat fits ur budget. i am not so sure for the prices but it's not very expensive. for HU, get alpine 9887 1.3k new or pioneer P80RS 1.6k new, or u can find some 2nd hand HU like eclipse 7100 or 7200, alpine 9835, 9855, 9812, 7998 oso can and cheaper. for mid end comp speaker ranges from rm700-1200, Boston Acoustics S60, Alpine type R, DLS R6A, Peerless Definition, Focal Access or Polyglass, Eton PRO170, Vifa drivers if u plan to play active and the list goes on. Amp: ~rm1.5 - 2k i suggest getting some 2nd hand amps for cost saving, ask zenn to recommend u some nice amps. dun worry abt durability of 2nd hand amps, gud quality amps are made to last long. then now to the subs, a single 12" sub will do rite? try to get a sub around rm500 then it will all fit to ur budget. just remember to stay away from china made brands and fake stuffs.

abt accessories shop i not so sure, u have to ask the locals. i'm from sabah so can't help u. active setup gives u flexibility in tuning i.e. independent crossover, EQ, time alignment and gain control on each channel, and each speaker gets its own amplification, meaning 4 speakers need a 4ch amp, the passive crossovers of the comp set are not used in this setup. while passive, like the name sounds, using the passive crossovers. not much flexibility in tuning. all these mostly depends on which HU u are getting and if the HU has the capability to play active.

it's better to get a seperate amp for the sub so dat it wun suck up too much power. and usually bridged 4ch might not be enuf to feed a sub unless u get a 150rms sub. i suggest 2pcs of 2ch amp.

u r into SPL? which Lanzar amps, they have lotsa series, got Heritage, Vibe and so on.

it's just like mercedes oso got different classes. every manufacturer has low to hi end products of their own. Lanzar i would say it's quite a gud brand for beginners. i've had Lanzar 6x9" before and it served me well. u can check the model at the official website or google it for more info and reviews.
