Hey i'm trying to wire up a sub and amp to my stock HU, as you may expect it does not have rca pre outs. Question is that i have the speaker level input on my amp (alpine), should i use that or should i go for a line level converter and use RCA's?
What are the pros and cons? do i sacrifice lots of sounds (bass and quality) by going the speaker level input route? I can get a converter but its non-adjustable, is that fine?
