I would like to upgrade my system.

[you da man]

Also, do you hit the party cove and float alot and do you plan on doing the install yourself (sounds like you're not because you say you're a "novice" at this). HLCD tower speakers are expensive but are worth it compared to coax type speakers. Your budget will be the main factor. Just to give you a hint, I have an average size upgraded system but with top of the line equipment (4 Bullet HP HLCD tower, 6 Bullet HP cabin, JL Audio sub, 3 JL Audio amps, 3 batteries, onboard charger, WS-420 EQ, and HSE Revolution) and total cost was just shy of $6,000 installed so you can see, your wallet and/or your wife may go into shock
