Hi guys, first of all this is my first post so sorry if its in the wrong area but i would like to ask a few questions if i may!

i have this amplifier Eagle Black PA4060E 60W RMS Mixer Amplifier

and i have 6 of these speakers White Compact Wall Ceiling Miniature Speaker 100v | eBay

My question is, this is going in my ceiling of the house i have bought but i have currently got the cable terminated into the 8ohm terminal as its alot louder that the 100v terminal, i have done some reading and i believe this is wrong but could somebody explain why please and if this will burn out or break after any amount of time? also im lookng to buy a ceiling mounted sub with this so has anyone got any suggestions please?

Also just to add i have it connected to my tv via a twin arc to 3.5mm jack, this is just playing around with it but has anyone got any recommendations??

Thanks!

I'd install an isolation transformer in the audio line between the amp and the TV to avoid any ground loop issues.

Am I running the chance of breaking my tv? What does the transformer do? How else can I improve what I'm doing?
Thanks for you reply buddy!

Hi,

Something is very wrong if the 8 ohm output is louder
than the 100V line output, it simply shouldn't be.
Conversely nothing will go wrong using the 8ohm.

60W 8 ohms is essentially a 22V line system, and
will give very limited output into a 6W 100V
speaker, about 0.3W on the 6W tap.

Thanks for your reply matey, so what tapping should I use on the speaker and I obviously connect that back at the amp (but which terminal the 100v line)?? And how do I connect the amp to the tele? I've tried twin phono leads but no sound comes out, I can only get sound if I connect a 3.5 jack into the headphone port then phono into the amp, sorry for all the questions!

Hi,

The tappings allow you to adjust relative volume,
Set the loudest at 6W and the rest relative to that.

They should connect to the 100V line output.
