I agree with you here ...The X02 and the X04 works really well ... but the best one is the X03 This one, I do not ...Linear Power is the only brand that hold it's value longer than any other amplifier brand in the world ... We do not know of any other amplifier product on the car audio market that sells "used" for almost the same prices for when they were sold as new products ... They are VERY well built and work just as good 20+ years later as they do when they were new ... ... And almost all Linear Power products are capable of being repaired and modified with more "up to date" technology ... I do not know of ANY other product that does this ... Now please ... End this and help the op with what he needs to get his system set up instead of bashing products ... Thank you ... No I meant an X01, there was one on the bay for 325. Wasn't going to use it, just add it to the collection. I disagree about LP amplifiers. I am a fan and while a lot are collecting Orion, Phoenix Gold, and old Alpine, I like to collect LP. I've decided on a 952, 3002, and 8002 to run in the Cadillac. They're all currently being paid off, upgraded, and repaired lol. I would not say they are overpriced, they are expensive. But either way, I'm a fan. Oh and buying used, repairing, and modding a LP amp is not too bad at all. A JL HD 600/4 is 799.99 msrp. I can say I paid considerably less for both amps, repair, internal mods by Jeremy, and hammer finish gold powder coating.
