I went on Bimmertech's website and when I put in my vehicle information, they did not have any amp upgrade options for it.
I was looking at Focal and Rockford Fosgate, but both were quite pricey. I heard about BAVSOUND and nothing but amazing things about them. They were also cheaper so I went that route. They sound great don't get me wrong I'm just bummed at the distortion from the subs.
But is there a way to find out what my amp/woofers specs are? I have an older model 5 series compared to you skrelnik
, it's an '05. I'm sure the components were improved or upgraded between pre-lci and lci models, hence the different part numbers.
