3. I don't look at nominal RMS ratings of speakers, it's one of those gray areas that once you've been in this hobby for a while you'll learn how insignificant it is. I do recommend at least a 50W amplifier for most people with my recommended at 75W.

But let's say you just have 30W versus a 50W amplifier, when all else is the same, the difference is just 2.2dB. Whether that additional decibel is important depends on you.

4. You cannot in your head unit because you do not have enough crossover functions.

Sa totoo lang.. malabo yun system mo and I attribute it because you're using the wrong terms in your post -- especially that midrange/midbass part. So I'll try to set your system up from scratch with recommendations..

Since you have a Pioneer DEH-P6900UB and a Focal Polyglass 165V1 component speaker..

For install, throw the Focal Polyglass at front -- tweeters near ear-level and midbass at the doors. For tweeter installation, I'll go for the cheaper option, I believe the Polyglass tweeter comes with a plastic enclosure so just throw that sa windshield mo, point the driver-side tweeter towards your passenger's head rest and your passenger tweeter towards your driver's head rest, and double-tape the bottom. Custom fabricated A-pillars aren't cheap.. even if they come from the installers in Banawe they'll still cost a few thousand and so.

The set also comes with a passive crossover that filters frequencies for the tweeter and midbass.. you can just install that anywhere where it's convenient. Some people install it directly on the doors while some throws it under the dashboard.

For the back, keep the speakers stock. If you don't have back speakers, feel free to get the ones in front. I'm not really fond of coaxials at the back and what I usually like are just midbass drivers. The problem with coaxials at the back is because the inclusion of a tweeter makes our head "aware" of its location and this drags our soundstage lower and at the back.

For the amplifier, the best one is something that fits your budget. Get 4-channels for flexibility's sake in the event you might have a subwoofer in the future. For now, use 2-channels for the front speakers and 2-channels for the back speakers.

For the tuning, I will recommend you do a slight front fade setting. This will make more of your sound emanate at the front speakers rather than the back.

Salamat po Sir for your prompt reply..

Sorry po Sir, talagang newbie po ako dito.. This would be my very first set-up kaya kailangan ko po expert advise nyo po..

Now I will focus on your suggested set-up..by this Sir, I will not use anymore my stock rear speaker and use a subwoofer.

Questions:

1. As I've read on your previous comment, is JBL GT5-A604 amplifier suitable for my HU and speakers?
2. Now this time, the 2 channel will be bridge na talaga po for subwoofer, tama po ba?
3. What subwoofer po will you recommend?
4. Or shall I buy a mono amp for my subwoofer?

Sobrang laki po ng tulong na maiibigay niyo po sa mga taong katulad ko nga bagohan pa lng..

Salamat po ulit..
