Hi. I have a 2000 civic coupe and want to add subs and amp. right now i have a pioneer deck and pioneer speakers. i was looking at this combo package they have at best buy but after reading around here it looks like i could do better than that. budget is $400 out the door. i dont really wanna mess with installation, or building a box, so i will probably end up taking it to audio express for the install. thanks for any help.
