Using support thread rods as speaker terminals also

[jrod1050 5]

Might be a stupid question but im gonna ask it anyway.I have a enclosure with 2 thread rods running from the front of the enclosure all the way to the back of the enclosure for support. Can i also use these thread rods for a speaker terminals also? I will be running a memphis 16-2000d to a 18" btl d1 voice coils. Will be running in a series for a 2 ohm load.

Only problem i could see is the rods possibly having some kind of electrical resistance. Only 1,000w for a BTL?

i have been wonderin the same.

The best way to find out is-

Get multimeter and touch the farthest points apart on the rod and see if u get any resistance reading on the meter.

If that isn't enough, send power through a speaker wire then through the threaded rod and see if there is a power difference.

Considering threaded rods are usually big in diameter, I wouldn't worry too much about resistance. If there is no risk that the rods come in contact together or come in contact to the bodywork of the car...go for it.

yea, i have 3\4" rod i'll be using. My multimeter only reads 1\10th of a decimal so i cant give an accurate answer on what kind of resistance it offers.

Ill try it out and see what happens. The 16-2000d is listed @ 2400 rms @ 2ohms 14.4 volts

It will add some resistance, but not enough to make a differance.

even on the mic?

What if i over-run wire? If i attempt to run 2-4 8awg wires per sub to the rod and the same amount to the amps... will that help on a meter or is that overkill?

[nem 2,019]

I am not sure how it would effect your spl reading.

[shizzzon 461]

ok, well i'll add that to my required testing on the meter, hehe.

I'll know in about 3-4 weeks.

well my install is going in a daily driver so i think im going to run with it. LOL. I might meter it just to see what kind of numbers im putting up but definately no competitions. I live in east nowhere Georgia so i should be the king of the block anyway. : )

i think i drove through east nowhere, GA on my way to Florida a few weeks ago because at some point in Georgia, my GPS lost signal and didnt know where i was at for a few minutes.
