Stuff needed to add a second amplifier?

greenhorn · 19th January 2013, 13:48

Got hold of a 4 channel amp via classifieds, now for the hard part of adding it.
I already have a 150W RMS stereo amp running in bridged mode driving my sub, and the associated wiring. Need to install the bare minimum stuff to get the amp up and running (will do a proper install + Damping later)

Can I just run a pair of power wires from the existing amp to the new one? maybe upgrade the fuse too, or are distribution blocks etc necessary? I'm looking for a bare bones install.

Without a distribution block, you would have to run another power line from the battery.
How thick is the current power wire to the 2-ch amp?

Hello greenhorn

You can cut the power wire near the existing amp and clamp a thimble on that . Then you can attach another power wire using a thimble with bolt in that which can save you from running new power wire . This is what i have seen been used by installer if person dont want to buy a distribution block . Please find the picture of the thimble i am referring to .

You could, since you are going to use it for a fairly short time. A DB is not a bad investment - makes the wiring safe.

I doubt if you are the SPL type. At the moment, you can drive both the amps through 1 central fuse - don't change fuse rating. With one power cable supplying 2 amps, there *just maybe* some voltage drop at high volume. If the power cable is not heating up unduly, you are safe.

It would be preferable to use a separate ground for the new amp, instead of jumpering off the sub amp. Easier to debug problems.
