So after asking an car audio store to order the Alpine MRP-f300 for me to buy, the owner tells me that they're out of stock and they won't be getting them for another month. But they had a Sony Xplod Gtx6040 in stock and after checking the reviews on my phone, I ended up buying the Sony, cause I didn't want to wait. But ever since something in me sort of regrets getting the Sony, even though it sounds good and gets the job done to say the least. Mainly because I keep hearing all these good things about Alpines, and the great reviews on the MRP-f300 in particular. Now at this point I COULD order the Alpine off the store's website, and ask for a refund on my current Sony. But I wanted to know, is it really worth it? I mean the Alpine would cost me about $20 more(not too bad), but the Sony isn't bad at all. Would I hear a difference in sound quality? If so how much? Since I just recently went ahead and replaced all my speakers( with Alpines), and my HU, should I dish out $20 more bucks and get a more critically acclaimed amp? Or would you guys save your selves the trouble(if this happened to you) and just keep the Sony Xplod? Please let me know what you think. Thank you!
