I have no issues with my aftermarket speakers and my Monsoon HU. I switched it out at first, but hated the look of the aftermarket radio. I am happy with my tape deck
People always ask about the tape deck when they see it.
I run Infinitys up front (wired kinda like component), Kickers in the sails, Kickers in the rears and Infinity Basslink in the spare tire area.
