I went to a car audio shop today and checked everything out. They have the 7894 on a $100 discount, which is amazing. So I think I'll pick it up. I did however get a good response on the differences between the 9813 and 7894 from another forum. Here it is:
Reasons why the 9813 is better than the 7894
9813:
6ch. time correction (all three sets of preouts)
2/3 way, 6 position,24dB xovers and adjustable slope
5 band parametric EQ
WMA files
Who cares about the better bass engine, it sucks.
7984:
4ch. time correction (subs not correctable, but the rest delay so the subs can sound like they are up front)
3 position 12dB xover
Bass and treble center freq adjustments instead of EQ
No WMA files
The 9813 doesn't look as nice because of the added LED's above the EQ, MX (which also is gay), and Xovers. That's only my opinion though.
I hope this helps.
SumAccordGuy94 - I wish to run the wire straight to the battery. What's the best way to run the wire from behind the deck to the engine bay? I imagine I'll have to do some drilling.
