1) I'm using a self-amplified Bass Tube (basicaly the same hookup as an AMP). I'm using the low-out RCA on my head unit for input, I know the power wire goes to the battery with the fuse and I've grounded it. What I'm confused about is where I connect the switch/remote wire and how exactly does it work? Do I need to connect it to anything if I want the amp to turn on with my car? If I don't connect it to anything will my Amp be on even when my car is off? What I want is just my amp/tubes to turn on when my car is on, I don't care about any fancy switches to turn the tubes on/off. Please help me here, I'm such a n00b and so confused. |
The remote is just that. It turns the tube on and off as needed. Your deck will have an output just for this. It is a blue wire. There are actually two, the other is blue w/ a white stripe. One is for turning on amps, the other is for extending the radio antenna on some cars. Honestly I can't remember if you want the blue or blue w/ white stripe. If you get the wrong one, the tube will only work while the radio is on, but not for CD. Look in the manual and it should tell you what one you want.

2) I have no idea what the amps are that I'm pulling, all I know is that I'm using an old Bazooka self-amplified bass tube with a passive bass tube slave running off it and a Pioneer 6500 head unit. What is a good amperage of fuse to use on this setup? Thanks |
Not much power. If I remember right the tubes were class a/b amps and put out 80 watts. With a slave tube they jump to 120 watts, making 60 watts per tube. The newer ones are jumping to 100 and 150 watts, but are class d amps now I think (more watts using less amps). The new ones use a 15 amps fuse from the looks of it. For the power wire just throw in a 30 amp fuse and that should be fine. Honestly the fuse by the battery isn't for the tube, its more to protect the car. If there was ever a short between the tube and the battery, this is the fuse that will blow instead of setting the car on fire. Internally the tube will have it's own fuse to protect itself. Usually you match the fuse or go a little bigger for the fuse by the battery. I have 2 amps, one that has a 40 amp fuse and anther that has a 30 amp fuse. So any fuse 70 amps and above would be fine in my car. I went w/ a 120 amp fuse in case I ever upgrade to something crazy, more amps, bigger amps, etc ..... then I am ready to go without upgrading the fuse.
