Re: Help with Rear Subwoofer and stock amp
Ok, as a final follow up I figured I would add a retrospective post.
I ordered a new set of speaker surrounds. The driver side sounds fine, so I left that one alone. The passenger side needed to be redone so I cut away the new foam between the cone and the frame. I was able to scrape the frame down fairly well, but the adhesive (seemed like contact cement) I used on the 1st repair was really strong on the cone. While I wasn't able to get rid of 100% of the surround on the cone, I was able to scrape a good portion off, maybe 80% or so. My thinking was that if it would not loosen with chemicals and a razor, it really wasn't in danger of falling off during use. Once I was done scraping I went around one last time with rubbing alcohol.
The new new repair kit came with a different adhesive. Instead of clear contact cement, this one was a black tar like stuff. I centered the newest surround and applied the adhesive to the edge of the cone. Then I cut the tip off of a Q-Tip and used just the stick part to gently push down the surround until it was secure all the way around. It took 3 or 4 revolutions before I was confident it was completely secure.
I then hooked the speaker up to a computer sound system and put a test tone through it per the post from ATX above (see page 1 of this post). The amp for the computer speakers really didn't have the oomph to push the Crossfire subwoofer, so I had to use a tone closer to 100HZ instead of 50HZ, but the process worked amazingly well. The surround went on fine and I used the T-Qip stick method for attaching the surround to the frame as well. I noticed that it was a tad off center and as I pushed the surround in a few places the I could hear the scraping very easily, so it was just a matter of not pushing the surround so far. It took me maybe 5 or 10 minutes and listening to that tone was quite annoying, but it worked great. If I ever have to repair another speaker surround, that is the method I am going to use.
Attaching the speaker to the frame and putting it back in the car was a snap. The speaker sounds great and I am loving the new sound system! It was a bit of an aggravation due to my mistake the with the first repair, but I think I not only ended up saving some money, but it seems like the stock subs are really the best option.
Thanks everyone for your help. Hopefully this post can help others in the future. It may be a sticky job, but in the end it is not that tough and it really does make the sound system sound great again!
