Park G10 amp at 4Ohm Speaker?

[gibson]

Hy Guys,

I wanted to ask if I can replace the amp's origininal 8Ohm Speaker with a 4Ohm Speaker. Will it damage the amp?

If yes, would a 4Ohm Resistor be enough to manage this problem?

Thanks!

HiGibson.
For an accurate response, please read and post what the Power chip code is, and measure the power supply voltage(s) It *should* have 2 voltages referred to ground, from +/-15V to , say, +/- 22V , but we'll wait for your answer. ¿Are you sure the original one was 8 ohms?
*Maybe* you can use a 4 ohms there.

The power amp chip is TDA2030. This chip can but used with 4 Ohms speaker but it depends on the power supply (shouldn't be too high). The amp with original speaker gets very hot so I don't think this is a good idea. It could work but you should improve cooling of the chip (add a fan?).

Thanks, very nice answers.

I think I'll try to improve the cooling, thank you for your good ideas!

I played bass guitar with this amp. I was surprised with a quite good quality of the sound but it is possible only with an external speaker. The chip was getting very hot but the amp is still alive. I would increase greatly the heatsink (and I would possibly add a small fan). Of course measure the previous speaker first - maybe it was already 4 Ohms. Check also the TDA2030 datasheet what power supply voltage is allowed with 4 Ohms speaker.
