honestly I'm not sure. I just ordered a used one and should get it in a week or so. I'll let you know how it works out, if your buying a new one I would imagine it would come w/a birth sheet.
I will pass on the Avionixx. Here's my new list of amps i wanted to buy:
1. Tru 4.65 - 65 x 4 - $450 or
2. Arc 4050 - 55 x 4 - $429 or
3. Arc KA$ 400.4 - 50 x 4 - $270 or
4. Audison SRx3 - 2 x 75 + 250w 4ohm - $450
So far i have researched that the TRU will go louder than the Arc Audio amps, more like 80-90 x 4 rms. Arc prices are getting cheaper if have time finding the right dealer. They are very popular now. Audison are new to our shores. The SRx are the their entryl level and saw one this weekend at a local dealer in glendale,ca. They are made in italy and are very small too. Here's a link on the SRx
