First of all I would like to thank Jacob for giving me the oppurtunity to buy his amp! installed The saz-1500 replaced my RFt10001bd, All I can say is wow! this amp had more balls,sounded better, and took less space! I am not the techie kind of guy but for a consumers point of view, the most important thing is that the product gave an improvement,it did not let you down,performed more than expected and most of all you know that you are backed by an excellent guy! The amp is driving 2 12" Oz MAtrix eLite head unit is a clarion hx-d2,seps are Legatia 631 and amp for the seps is an Audison Lrx 6.9. I wouldnt hesitate to buy from jacob again, he is a nice gentleman to talk to and deal with. I also hope he can make a 6 channel amp, 100 x 4 and 150 x 2 in one chassis would be ok! If there is one thing I dont like about the amp, that would be the choice of lettering for the label SAZ-1500D on the bottom righthand portion of the amp, hope it could be changed to a more serious looking font. But overall, the choice of chassis is elegant and build quality is top notch! If only I had the money to import this to the Philippines, I could be rich by now since I am sure that this product would sell a lot here! Jacob, I hope your prospected dealer here would push through with the dealership program! Thank you very much again Jacob!!!
