thanks Guys ! no problem Max,
thanks to You Gentlemans I know at least radio is fine. Looks like amp need to be repaired then.
Max no mark levinson no problems. thats good side of Your setup. Hopefuly it will payback that 300-400$ repair cost with great sound quality !
that will be last thing i will do probably in next few months. Next step is taking GX to trans/diff shop to find whats that humming noise in back. I bet its pinion bearing so im preparing mentally for diff rebuild $$$
good news is i got 2 brand new tires since bridgestones that i have on rear axle they have lot of meat but due to age and car sitting on flat tires they have micro cracks, i was lucky and i found localy on craiglist 2 brand new achilles desert hawk 265 55 17 brand new for 120$/pair i didnt think too much for that price, plus they match front tires

maybe they are not the best but have good reviews and for winter anyway ill get winter tires :]
