I did the center channel swap today and it went off without a (major) hitch. My only notes are:
- There is a tiny tab on the back of the existing plug, so make sure you have a small tool handy to depress it while disconnecting the existing speaker. Probably everybody knows this, but it took me a minute to realize.
- Despite using what I felt was great care with a trim tool, I slightly crushed the front lip of the center dash grill, so there there is a now tiny gap when replaced. I don't think very many people would notice this, but maybe go slow and take care to keep what is, I guess, some delicate plastic unscathed.
- The existing wire connection is fairly short without much slack. Not a real problem, but just be aware you will have very little room to work/do the splice and I'd suggest going slowly so that you won't need to cut off any more in case you mess up. Honda had wrapped it with some nasty duct-tape style stuff that took longer to remove than the rest of the splicing operation took. I used open-barrel connectors and a ratcheting crimper and then covered the splices with heat shrink tubing. Soldering these would probably be the bulletproof thing to do but I felt secure in my crimps and thought it would be a tricky place to work a soldering iron (even a butane portable). I used speed clips on the speaker terminals but also soldered new hookup wire to them. Crimping would probably be totally fine here but since I could easily take the speaker to my workbench, I did.
- According to the Crutchfield doc, and as was the case in my RTL-E, tan is positive and light green is negative. The Hertz speaker has a small red dot on the positive terminal.
- The Hertz speaker drops right into the grill with no modification needed, but it only fits one way due to the shape of its mounting slots. You don't need to use the Hertz clips or bolts, save the bolts from the Honda speaker.
It does indeed sound great! Definitely a high bang-for buck mod. Less than the cost of a tank of gas (if you can split the speaker set with someone else, which doesn't seem to be a problem around here).
I'll aim to tackle the front door and pillars this weekend.
Thanks again to
