what its a 4 channel amp it can power subs just wont have full poweri wouldnt go for 6x9's if you are getting a sub tbh, you are better off going for amped front components.
reason for this i believe is that having a sub effectively drowns out any sound gains from the 6x9's effectively making them useless. i would also check that you can run a front/sub setup, as im not sure if you can with those amps. might be wrong though
thats what i meant. i wasnt sure if it could to 3 channel mode with bridging.what its a 4 channel amp it can power subs just wont have full power
mate firstly not being funny you bout a a vibe amp there sound quality isn tthe best but it will do
you need to look at what setups you can do as if you can run it in 3 channel mode then do that set of front components onto channel 1 and 2
then bridge the sub as it will receive more power
