I'm looking for the cheapest 600 W or greater monoblock amplifier at 1 ohm. I haven't ventured on these forums in forever and have kind of gotten out of the audio field.
Cadence makes a 700W mono amp that sells on ebay for 100$ ish. JBL makes a 1200W mono amp that'll do a little more but the refurbs can be had on eBay for 125ish...both direct from the company stores.
