Remember – I am non-technical. I have tried to read as much as possible about replacing the dash speakers/squawkers and got some of it, and on others get lost . I am just looking for the simplest/easiest route possible. I have already replaced the front and rear door speakers. Current car and speaker info: 2013 Prius, non-JBL system, 6 speakers no sub Stock HU (do not want to replace) Front doors = Infinity 9632cf 6x9 Rear doors = polk dxi651 6.5 round To be installed in dash = polk dxi350 3.5 round 90Hz-22kHz From what I have read, the dash speakers and front door speakers are wired in parallel. There is a stock bass blocker on the stock squawker, but full sound/range goes to the front doors…correct? I have gotten to and removed the stock dash speakers and have seen that the new dash speakers will fit with little cutting. Is this the easiest/simplest things to do: In order to keep and use the stock wiring and plug, just remove the stock bass blocker and attach it to the new speaker. Will this do the trick? Or should I use some other type of bass blocker…inline capacitor to “+” side. If this is done, I am not sure on how to wire it all, if the stock plug is removed. If I do have to buy an in-line bass blocker, what/which one would be best for the new speakers? Crutchfield has: (150 Hz cut-off) (300 Hz cut-off) (600 Hz cut-off) (800 Hz cut-off) …or other… Plan for the future, towards end of year, is to have an installer put in an amp and sub. Thanks for any and all help…Paul.
I did read your document for the dash speakers but my new dash speakers do not have a built in crossover, like you mentioned yours did. So I still have my original questions regarding the stock bass blocker or some new bass blocker. What might be easier or better suited for my situation? Can I just do what you did, but put some new bass blocker from crutchfield between the stock plug and the new speakers?
I put in a 200 microfarad non polarized electrolytic capacitor. My concern was that this would provide a lower impedance load to the head unit, and I fear the head unit may not like low impedance loads. So what I did was install a 2 ohm resistor in series with both the squaker and the door speaker. This way the lowest impedance load the head unit will see is about 3 ohms. Since I now have a JBL-ms8, I will be removing the capacitor as well as the resistors. It is nice getting a wider frequency range from the squaker, but I have no idea what would happen if I didn't have the resistors in place. Given the head unit is quite expensive, I decided it was cheap insurance.
lopgok, I believe my factory HU and stock speakers were all 4 ohms, and the new speakers are all 4 ohms...Is this something I should be worried about? I have the non-JBL version with 6 speakers. Does anyone know what kind/level/range the stock bass blocker is? If I was to go with a xxx microfarad non polarized electrolytic capacitor, which one would be appropriate for my new dash speakers (polk dxi350 90Hz-22kHz)? 100, 150, 200, ... For the other front and rear speakers, I assume I just want the full range going to them. My concern now is if the stock bass blocker is ok or should I get a xxx microfarad non polarized electrolytic capacitor. Thanks all for the help.
The dxi350 is a coaxial 2-way driver. Usually, a coaxial driver will have its tweeter "internally" high passed already. As for the woofer part, the 150Hz hi-pass from Crutchfield will do. The stock squawker has a cap soldered in, and you can definitely use that. Desolder it from the stock squawker and wire it in series with the coax. I have no idea what frequency it filters and personally I wouldn't use it. FYI, the Prius speaker wiring goes like this: HU -> Dash Tweeter -> Door Woofer There is a set of wires from the HU that connect TO the tweets and THEN to the door speakers.
JGI...thanks for the info. After doing more research and reading more to understand, I read that the stock bass blocker on the stock squawkers is 6.8uf (or around 6000hz). I have decide to get some bass blockers from Crutchfield, but they recommend based off of speaker size, to get for 3.5 size speaker: (for low power system) 600hz (for high power system) 800hz I did read my new speakers Polk dxi350, come with a 200hz bass blocker, but I don't remember seeing them in the box, but will recheck.
