Like the saying goes, you get what you pay for. I agree totally with ExtremeRS, if you buy cheap then you'll be buying again and agian over time. If the amp you have now is still working and doing a fairly decent job then leave it in for the time being and save some more cash and get a good amp. Better to do it right the first time. As far as decent amps, I ran and still run 2 of the original Alpine 3522's for my mids and highs and they have been running strong for 8 years now. Just steer clear of things like Rockwood, Jensen, Audiovox, Sparkomatic, etc and you should be OK. If you ask me you can;t go wrong with anything good, ie....Orion, Rockford Fosgate, Alpine, Soundstream, Pheonix Gold etc.........Yeah they cost a lot more, but I gaurantee that a 25x2 Orion HCCA 225R will out perform any of the 100 dollar 3000 watt amps any day of the week.......
