Best Head-Unit for expensive sub-stage and bass only

[DedicatedEnthusiast]

Considering upgrading my entry-level pioneer DEH-14UB Head Unit IF it will make a notable difference in output or sound mainly in my sub-stage going with a upper-class pioneer, kenwood or alpine deck with 4-6v pre-outs. Tell me what do you guys think? I already have the entry-level pioneer wired up to a clarion MCD-360 crossover with 5v max output voltage so am I really going to notice a big difference in the bass production from the subs or no??

Any and all input is appreciated thanks:)

I don't think you'll notice anything. Ear or meter. :shrugs:

If you need more voltage, you can always add a line driver too.
