Oh and on the having the 6x9's playin full range. I personally would disagree on that, if ur amping them aswell. 6x9's wont play the lower frequencies as well as your subs will so it probs wont sound as good as it could. personally i think you would be better off high passing the 6x9's to a frequency just below the cut off for the subs low pass to keep a smooth trasition between frequencies. The main cause that could make it not sound as good when having the 6x9's playin full range would be that, if your rear loading your sub(s) the air pressure in the boot will possibly be pushing the cones of your 6x9's in the opposite direction they want to go which can cause problems. However if you are just gonna run the 6x9's off the H/U then may i suggest just fading most of the sound to the front.
update: i have wired up the amp to the boot... it all looks good and works. so all i need is a box and i'm done.
btw, i got 6 metres of 8 guage shielded wire and a metre of unsheilded all for 5 bucks off a mate who is an auto electrician. i got the remote wire, rca's, fuse case, fuse and connectors from local car stereo shop for 50
Yeah when I said to run the 6x9's full range, I was asuming that they were to be run off the deck. And with high pass filters on most decks set at 125Hz, this point is too high for a smooth crossover. This is because most low pass points on amps are set to 80Hz. But if you have adjustable crossover points then you're right on the money VL Commy! Either way though, my personal taste is to have them faded almost completely out (just enough volume for passengers and a touch of fill). This way the 6x9's won't interfere with the saging that you've set up in the rest of your system.
UPDATE: all done! its amazing how much you can learn from doing something like that by yourself... i did have some help with connectors from my mate the auto electrician. thanks to everyone for their help
