2 12" Subs
What are you looking for in these, Louness? Sound Quality? a mixture of both?
Also have you considered a single 15, that will be more cost effective, and allow you to buy a higher quality speaker for the same price.
Mixture of both really, I listen to alot of Dupstep and Techo/House. And no I have not considered that, mostly because I'm new to all of this.
2 Sets of speakers
Again, Loudness, Sound Quality? How much power are you looking to put out, what size of speakers do you need, have you considered where to mount the tweeters if you choose a component set?
I believe I need 4.5 and again mixture. For power I have no idea, I'm asking the wizards. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
Head Unit
What features are you looking for? do you want it to have USB, AUX, Bluetooth, iPod support? are you looking for something that has a removable faceplate?
AUX is necessary, Bluetooth and Ipod would be a cool plus, but AUX would cover both my Phone and Ipod. Removable faceplate I think is another must.
2 amps
This mainly depends on the speaker choice, but do you have the electrical to support 2 high power amps? have you considered the cost in replacing the battery under the hood and perhaps even adding a second battery?
Honestly, I haven't considered any of that, You're input would be greatly appreciated.
