$300-350?How much space & $$$ you have to work with?

I really don't trust Rockville. I would buy a PPI or Orion before Rockville.There is always amps like this: https://www.amazon.com/Rockville-dB...ncoding=UTF8&refRID=9TQ98WE4MZY5SYM014QZ&th=1
But your first post stated "good amp with clean power" and I'm not sure these could be classified as so.![]()
How about the BRX2000.1D for $189.99?Two ninety-nine - BRE2500.1D

A sundown amp , class d will be the ticket.
At that price , refurb or used .

Wire all four parallel / parallel for 1/4 ohm @ amp. Sundown will work @ a quarter amp
I have 4 image dynamics IDQ-8V.4D2 at 500 RMS each, what would be a good amp with clean power to buy?
Thanks Guys for all the input I have decided to go with Synergy Audio WFO 15.1D 2000 RMS for $399.99.Sundown amps are "good clean power" and customer service is `Top Notch`!
Play it safe ... get more than you bargain for
