help choosing 6.5 components and 4 channel amp

[Emilio Tizzone]

Good Morning Guys
New to this forum, seeking help for a SQ Setup

have been doing some crazy researching all night and day about the best set up of 6.5 component speakers and 2/4 channel amplifier for my 2004 Holden combo caddy
i would ideally like to have 2 set of 6.5 components in the front doors and a high SQ 2/4 channel amp that can run everything with out issues.
or my other option is 1 set of 6.5 components in the doors and directly above the back of me a pair of 6x9 boxed with a 2/4 channel amp
have been doing heaps of research on 6.5 components and have come up with a couple speakers listed below
wanting to push 125/150 watts/rms each speaker and looking for them to get crazy loud and still maintain good Sound Quality
- Hertz HSK 165XL

- Hertz HSK 165

- Morel Temp Ultra 602

- Polk Audio MM6501
- Rainbow Germanium CS 265.25
Has anyone here had experience with these speakers and could guide me the write way?,
i dont mind spending $400/500 (AUD) on a set of components
Also would like help choosing a good SQ 4 channel amp or even 2x 2 channel amps that will be able to handle 125/150 watts/rms each channel for long periods of time

suggestions and help is much appreciated.

Great quality speakers can handle a lot of power and the ones you have listed will all get loud and sound damn good doing it, but it is one of those things that are more personal than just our recommendation , it really is best to try and find shops that carry what you want to audition to get a better idea on what you like.

There are those that like each brand for their own reason which is valid as they have had great success with the brand.

You cannot go wrong with any of the brands you listed plus a ton more that have not been listed.

thanks heaps for the recommendations,
i might head down to the shop tomorrow and test them out, im more leaning towards the morel ultras and hertz hi energy tbh.
although every dealer has speakers on display running of the head-units, a bit hard to choose with out an amp to hear them at there best.
is there any possible recommendations on a 2 or 4 channel amps that can handle 125-50 watts/rms each channel for long periods of time and that offer clean power and SQ.?
i had a look at a - JL Audio HD600.4 - but have a couple more options of amps in mind

- Precision Power PPI P900.4 - dont know much about these amps ?

- ARC Audio XDI 600.4 - heard are good

- CT Sounds AT-125.4 / CT Sounds 125.2 - dont know much about these amp ? have seen people recommend them to others

- SoundStream p4.800 - dont know much about this amp ?

- Rainbow Beat 2 - heard are good

- Nakamichi N4 - heard Korean amps are really good

feedback or suggestions guys ?
Thanks

Also forgot this amp - Sundown audio SAX-150.4

[Masterbasser]

I have the nvx jad 800.4 which is same as ppi 900.4 basically. good amps, running each of the 4 channels at 2 ohms, no problems as of yet. it is a class d 4 channel though

[Carnines]

Don't worry too much about the brand of amp, find a reputable brand of amps and have some overhead on power. Invest in a good dsp/eq.
