I am looking for a 5 channel amp to run a JVC KD-NX5000, front/rear speakers and a JL Audio 10" Sub. Bought the sub and enclosure from StickerCity to mount behind the seats. Would like to find an amp to power all that would fit behind either the driver or passenger seat. I've searched the forum but am still confused as to what to buy. Am replacing the front and rear speakers with Infinity Kappas. Want a really nice amp but want to make sure what I buy fits....plan to purchase online and have a local guy that will install. Thanks in advance for any help.
