I was just wondering if anyone on here has experimented with the new line of the Kicker IX Amps before... I'm really liking them more and more I look at them being fairly smaller in size, and stackable! I'm thinking of repowering my system with the 500.4, 1000.1, and using the stock 350.4 for the cabin speakers. I guess I'm concerned with them dissipating the heat being as small as they are. If you have used them or dealt with them, let me know how well they performed. Pics I just pulled from ebay, hense "sonic electronix" logo.
