Hey I have a JL Audio E1400 Mono amp 500w rms. The amp is under rated and I have had it tested and it was hiting 562w.It is a GREAT sound quality amp with a-lot of clean power! Its about a yr old now and in the box, I had it in my explorer for two moths but I got another 12w6 so since I had two of them, 500w each, I had to get a bigger amp. The amp is in its box in my closet. I was about to list in the classified but thought I would check here first. I can let it go for $220. PM me if u r interested. Thanks
