I know others have asked themselves countless times which components should I get and how much should I spend. So far the unanimous choice for under the seats appears to be the SWS-8. My selection for the amplifier was based on reading one of Technic's posts about Arc Audio amplifiers. I must have changed my mind a million times on which Arc Audio Amp. Thats where I sit right now. I am waiting for a harness, door/rear speakers I have not decided on yet. If I've missed anything all suggestions are welcome.
