I don't think you really need to go until 4 subwoofers. Just get one 15" subwoofer powered with at least 800w RMS and one pair of component speakers (power by at least 2x400W RMS) for the front. As for the rear, just leave the OEM speakers to be powered by the HU (for the surround sound). Make sure get good quality amplifiers (power is most important here). By the way, don't forget to get a set of comp. speakers with very good mid bass and able to stand the power as you need them to complement your SW.

The 4 speaker that I mentioned just 6.5' component speaker without any sub install 
I read your post about the Agako amp, giving good complement to this amp 
really feel to have a bite on it   
but this brand not familiar here, and also not much info available in the web.

Greetings all.

I'm planning to get my car's speakers changed to a component set while retaining the stock Clarion HU. My budget is RM800 max. Currently looking at :

- Infinity Reference series
- German Maestro "A"-series
- Dominations (not sure which, but the one around RM700-800 gua)
- Boston Acoustics (not sure which series/model too)

Of all above mentioned, which is most recommended?

All feedback and suggestions/recommendations are generously welcomed.

Thank you guys!

Boston Acoustics SX60. I guess should be within your budget. zenn got sell but dunno if his is inclusive of installation not.

You don't need amps and subs?

so it's abt 2k for the whole system... u need 1 4channel amp(~700), HU with USB(~500), 1 compenent set(~500) and a 10" sub(~300). as for which model very hard to recommend cos got a lot of varieties.

Is that the best amongst the list? I have not personally heard them yet so I can't be a judge of anything.

Well I want to, but my current budget is only RM800. So I guess I shall go for a decent set of components first.

Thank you for your reply tho!

edit : Oh and, what's the main difference between the S60 and SX60?

The main difference is the model number...the "X".... 

No la, SX sound different. A bit clearer and higher pitch...can be said as clarity also.

Anyway, go audit one before you want to buy.

if 800 can get la SX60 with installation
difference between SX and S is the tweeter, SX one nicer sounding, bit more detail

if can stretch to 900 can get u Eton Pro 170

Ahh, I see I see. Tried to Google for the difference but can't seem to find any significant difference between the two.

Thanks for your feedback! Oh and, what do you mean by "audit"?
Thanks for the clarification. Appreciate it.

Eton.. Is it much superior to the SX60?

What do you mean by superior? In terms of technical specs?

Audit is go listen to it, then choose which set you like the most...

Sometimes ppl can say earth and sky, but if you don't like it... it won't worth a single penny.
