Hiya

1st post on here and looking for a bit of help if possible?

I've got a Mk 1 Punto and I've added head unit, 6X9's and upgraded the front tweeters on the dash.

I now want to add a sub and front door speakers.
Firstly, will I have any troubles installing door speakers in my 85 SX with the electric window motor?

Secondly, I'm not the most technically minded person but when I choose my Amp, will I be able to power a sub, 2 6X9s and the front door speakers from it and then also power the tweeters from my head unit as they require little power.

The setup sounds good at the moment but when loud, it starts to distort slightly.

Any help greatly appreciated.

Cheers Guys,
Jay
