Which of these amps is best for component Fronts/Sub?

Hi there,

My first post here...

I'm wanting to amp up my Rainbow SLC 165 NG Components, and also get an amp in the very near future for my Subaru Legacy Wagon.

The Components are rated at 100w RMS. The Sub wouldn't be a HUGE one, or need to be shaking the whole car, yet I assume in a larger car (wagon) some of the bass would be lost. I'd probably go for a 12" sub.

Prices in NZ Dollars is about $150 for an amp install. Options are...

Pioneer PDRS4100F Class D 4 Amplifier $549
products

Fusion Encounter EN-AM60040 Amp $399
FUSION Electronics

Sound Magus C160 (like this one?) $449
products

Fusion Reactor RE-AM90040 $599.99
FUSION Electronics

Sony Xplod XM4S $449
XM-4S : Xplod™ Amplifiers : Car & Marine Entertainment : Sony New Zealand

Thanks if you took the time to view the links :veryhapp:
Amps are kind of expensive over here, so they may not be amazing quality, but all I can afford... Fusion doesn't have the greatest reputation, but are kinda powerful.

Thanks for your opinions,
Jonno

PS: I want to get it professionally installed, as I'v had problems with altinator squeel through the fronts before.
