Memphis Sub/Amp & Kenwood Excelon Speakers?

So, my car has Kenwood Excelon speakers. This is what I got from GoHo Audio a few months back. I called them today to get a quote so I can start saving and turning my ride, 07 Galant, into something nice. I asked about the speakers, if I needed to upgrade, and he said that The Excelon were good speakers, I just needed an amp. He recommended one and with installation it was about $400. Now for the subs, he recommended two 12" Memphis something, that with an amp & installation, cost around $850. He said they carry 2 or 3 stronger subs, I believe Memphis...but that's $1000+ money and possibly new wiring. I don't need all that. I asked about JL subs and where he did admit they were better, he said the price isn't, and Memphis gives me plenty of bang for my buck. The 12's come in a ported box. I wanted something that would turn a few heads. Not necessarily a 8.0 on the Richter scale, but no more confusing my car, especially the sub w/ a loud cell phone. How does that sound guys?
