Been lurking a bit, first time posting. I just bought a 2015 Chevrolet SS that comes with a Bose system. The stock system is absolutely terrible and lacking in bass and detail. I live in a fairly remote town so driving down the local car audio shop and listening to speakers and systems is not an option for me. I am however a reasonably handy DIY kinda guy (and love to tinker) so with a bit of advice and guidance I am certain I can put together a system that will exceed my own expectations.
As far as music, I really listen to a wide variety of Country, Rock (hard and softer), Pop, Classical, Hip Hop, Classic Rock, etc. so I will need something that performs well in all categories. With that said, the amount of time spent listening to each genre generally matches the order I presented them in above (if that matters). I do like a good bit of bass (dont want to shake the cars around me though, thats obnoxious) and I notice that if I ever reach to turn the music down its due to shrill and fatiguing highs so will definitely need a tweeter that is not too harsh (but still accurate).
I need to keep the stock head unit, but I am looking for the best way to upgrade the front stage (6.5” in doors and 1” tweeter in pillars) and add a subwoofer in the trunk. This will probably be a bit long winded, but I want to give you as much information to work with as I can.
I have not really set a budget because I’m not sure where to start. I will say that I am looking to achieve a system with good SQ at as low a budget as I can. Essentially, once the prices of components begin to hit a level of diminishing returns we are probably in a good place. I could probably stomach $500 in front-stage speakers, and then the rest of the supporting components just cost what they cost.
I have been reading about the Dayton Audio DSP-408. Is this something I should incorporate into this build or is there a better option out there for me? My initial thought was that I could utilize the factory bose amp to power the new speakers and use whatever DSP I end up with to correct and EQ the signals being sent to them (is this a poor idea?). Additionally, how do I determine what kind of signal (high or low level) my HU is sending to the factory Bose amp?
I have a subwoofer (12” Sony Xplod) and a mono amp (Alpine, 1x500W RMS) to put in place for the time being and allow me to focus on the rest of the system. Should I consider upgrading the subwoofer in the future? Not sure how the Sony compares to other subwoofers on the market.
I will be picking up some CLD, MLV, and foam (forget the acronym) to properly sound deaden the doors, trunk, and cabin floor. I’ll certainly take advice here, but think I pretty much have it covered already thanks to some great info available on this forum.
A few additional questions I have:
- Is there any benefit to replacing the 8” woofers in the rear deck since I will
be running a subwoofer in the trunk? Or should I just remove these
- Should I look to see if the NavTV M650-GM interface is compatible with my
HU? Is this something that would benefit me, or what is the best way to go
about retrieving the best signal from the HU to send to a DSP?
- Which speakers should I consider for a semi-budget minded build with
sound quality in mind? Best value for the money essentially. I have seen
Audiofrog thrown out quite a bit, and have also seen some SB Acoustics
speakers thrown out there as excellent value for the money.
If I missed something feel free to ask. I look forward to discussing this build and am wanting to get going on it pretty soon. Thanks in advance!
