So I'm thinking of getting a new HU. What I have in mind is the Clarion CZ501. I'm sure there's others out there. What I'm looking for is a unit with 4v or higher RCA outputs, 6ch RCA, H&LPFs. USB and Bluetooth. This will be for SQ mainly. Willing to spend bout 200 on one. Prefered manufactures are Clarion, Alpine and Kenwood. Not too into the flip out decks. Single din. If someone has any experience with the CZ501, would like to know how it performs. Need suggestions on other decks.
