We use Viper and Prestige by Audiovox Alarms and like them both

As far as your Audio those DB Drive PLW12D2 Subs are some excellent Subs they will handle abuse to the max and put out some serious bass for you,

Your Quantum Audio Amp is actually capable of doing in the neighborhood of 2000 Watts RMS if I remember correctly which is a good match up to those subs

So your mids and highs should be something serious to keep up with your Bass

I am not sure of what you are looking for but what you are starting out with is a head banger set up which is usually coupled with Loud Speakers or a boat load of Coaxial Speakers in order for the voices to keep up.

So if Loud is your main goal try Selenium Loud Speakers
