Today, when I should have been studying for final exams, I installed my new sub and amp in my car, essentially completing my audio upgrade. A couple weekends ago I replaced all the 5.25" (4 total) and all the tweeters (4 total) with MBQuart RSC 213 Reference Line component speakers, and after much, much appreciated help from
jllphan, I ordered my Kicker CVR-10 sub and Alpine MRD-M300 V12 amp last week.
Before I go any further, let me say that I know to many of you this is small-fry stuff, but this is the biggest audio upgrade I have ever done, and as jllphan will attest, I knew almost nothing when I started!
I post this information for other E39 owners who are on the fence about digging into their precious German vehicle, and for anyone who is as unexperienced with car audio as I was. Let me tell you: if I can do it, you can do it. What an incredible difference! The sound is now round and full and clear. It's just what I wanted, and it was done for a grand total of $500:
Sub: $80 shipped (brand new from eBay)
Amp: $170 shipped (also brand new from eBay)
MBQuarts (2 sets of 4): $180 shipped (brand new from eBay again)
Box: $40 Circuit City
Misc wiring hardware: $30 hardware store
As you can see, I bought the big stuff on eBay. Granted, there is a risk in that, but I've learned to be a savvy eBay shopper and know what to look for. Everything I bought was brand new and still sealed in its factory packaging, and for all three (sub, amp, and speakers), I paid roughly half of their retail cost. So I saved quite a bit.
As I said, the sound is great. I didn't even have to punch a hole behind my rear armrest like many bimmer owners do to be able to hear the sub better. The sub and amp can actually easily overpower the rest of the audio system.
I will try to post pics of how I mounted and wired the sub tomorrow night. AFTER my final exam
One more thing I think I want to do: I want to put midrange crossovers on all of the 5.25" MB Quarts, because they're still trying to pump out bass (which is a joke), and when I turn it up they start to sound a bit muddy. I have compensated for this at the moment by keeping the bass on the head unit almost all the way down but turning up the gain on the Alpine (sub) amp. Any advice on this plan?
