From the looks of those specs, you can run those interior speakers off the deck. Preferably a high powered deck like an Alpine
, they'd like that. A quality high end Alpine can put out around 18 - 20 watts rms. That's about as good as it gets from a deck.
Sub play frequencies below 80hz.
My own definitions of:
High bass = 80 to 65hz
Mid bass = 65 to 45hz
Low bass = 45 to 20hz
A crossover is a must for a sub, any halfway decent amp will have a built in crossover.
btw, a channel is the output on an amp for a speaker, one channel has a + and - pairing to hook up a speaker to. A 2 channel amp can play 2 speakers, a 4 channel plays 4 speakers, and so on.
...and whose MB Quartz? Do they make digital watches or something? lol.
