Questions about the BTA10250D
 

I'll be purchasing this model within the next week, and I have a few questions about installation steps and what I should buy for installation.

Here's what I can find:

And:

My questions:
So...How long are the wires that come with this unit. I believe I am reading that it comes only with about 19" (including fuse) of 12 gauge power wire. Is that correct?

If that is correct, and the power wire is only 12 gauge, should an 8 gauge CCA (copper coated aluminum) wire be a sufficient extension?

Also, will I still need a fuse box/fuse, the kind that comes with an amp installation kit?

You do not need to use 8 gauge for the power wire, 12 gauge is plenty sufficient for the Tube. Not to mention, it makes it easier to connect to the in-line fuse holder and the harness of the Tube.

No, the in-line fuse holder that is supplied is all you need for the installation of the Tube.

As for the length, the in-line fuse holder may be 10" long, to be honest, I've never taken the time to measure. As for the harness, these wires are most likely 12"-16" long.

Wow, thank you for the quick reply, Heavyduty. (^_^)

I already posted this Q in my introduction thread and I hate to ask twice but, maybe if the answer is here, it can help anyone else who ends up with my same questions:

Should I connect to my head unit's 2.5v RCA sub outs or tap into my speaker channels? If I use my sub out, I can use the low-pass filter in my HU to block the bass frequencies to my factory speakers. But, I see the recommendations in the FAST-9999 thread to always use the high-level inputs instead. My HU claims it puts out 20 watts RMS x4 channels at 4 ohms.

I'm not sure which is considered the high-level input for this tube. And, if the RCA's are the lower choice, would it be worth it, to use the bass filter in my head unit?

Thanks again. (^_~)

Take advantage of the subwoofer output of the headunit.

The High Level Input is quite simply connecting to the speaker outputs of the headunit. The voltage level is high, thus, High Level Input.
