to amp or not to amp?

[techietam]

How are you doing, guys.
I am kinda new to aftermarket car audio and need an advice

I got me Kappa 6x9 and 60.5 Kappa components.
Also have RF 360.2 amp and Infinity Perfect 10" sub.

I am about to buy Alpine 7894 HU which has 27Wx4 RMS amp

How loud is it? I just want to make sure that I don't have
to rewire the whole thing incase I need more power to the speakers.

Will I see the difference going from the factory Infinity system
that was installed in my 1998 Chrysler Sebring LXi

If I decide to go with RF 550X Amp, will 15 gauge wire
handle 70W RMS that will go to speakers?

Please, help!

Itll sound alot better with amp...15 guage should be fine...though personally i use 12

15ga should be plenty big.

Kappa's are power hungry, get the amp.

It's a sin not having an amp for component speakers. I mean why spend the extra money on components when you are just going to use the HU's amp to power it? It's like buying a car so that you could push it to work.

Alright. I guess I made my decision to get the amp

Is Rockford Fosgate 550X, 65x4 enough for that?
