My Other Car...

Purple stuff with rain repel. Kept some in a spray bottle to mist off the thin frost on the side windows and flick it off with a water blade.

I finally got one mounted the other day, I had to tweak the trunk torsion springs a little to keep one from sticking itself to the magnet. The hole pattern is a little different so I had to drill new holes, not so fun working in the rear deck area, luckily there's a nice 90 deg air drill and special metal bits that start with no wandering for me to use at work. Those bits sail right through structural and hardened steel like nothing! Amazingly all 4 holes lined right up with the speaker perfectly. Installing the speakers will be the easiest part, it's going to be getting the amp cabling ran and installed that will take the longest. I still don't know where I want to stick the amp, I'd like to leave under the drivers seat free but that may not be an option unless I can mount it in the trunk off to one side somehow so I don't loose any luggage space. That means running power further though, so maybe under the seat will be best. I can mirror the routing of the RCA's and power cabling for the front amp. Why two amps? The power handling of the front and rear is too different. Fronts are about 3 ohm at 100-120W and the rears at 8 ohm at about ??? watts. For the rears I just play with the gain till they sound right, there's no spec on the amp for 8 ohm loads but I figure it's about 1/2 a 4 ohm so in IB I'm going to shoot for about 50-75W RMS which is fine. IB lowers power needs and makes the speakers more sensitive, sort of. I couldn't box them in the rear deck if I wanted anyway, the trunk torsion springs are in the way. I would have to redesign that system.

Nice - yeah, drilling on that rear deck can be a pain without the right tools. How big are those amps? - might be able to mount them under the rear deck. I just picked up some cheap class T amps (Tripath tech) - that are pretty shallow in design. Might try to pull them out of their cases and rework some of the components on the board. Might be able to get them to sit under the rear sail panel area.

Yea, the only problem is the power ratings listed online are a little...confusing. Some list it was XXX W peak and other places list that as the RMS wattage with no peak ratings.

 

Good news is that my old JL 300/2 V1 just got fixed, does 330W real power, and is on it's way back. I don't have an application for it though since anything I run IB won't need 150W each RMS and due to depth limitations I can't do anything too crazy with the front door speakers that would need that kind of power.

Ok so I decided to just use the JL with the 2 Tang Band in parallel for a 4 ohm load on the JL bridged. Those 6x9's sounded terrible at first. Now after about 4 hours play time they're sounding very good. I ended up flattening my EQ a little more (less bass) and set the fronts high pass to through instead of 40 or 60hz. The filters in the head unit are way too sharp, so when it says 40hz high pass it means it cuts SHARP at 40hz and NOTHING below 40hz plays at all. I'd like more of a soft filter around 50hz on the fronts but whatever. I can probably do that later with a little passive circuit if it's bothering me too much or get a nicer amp for the fronts.

 

 

So on to the rears. Wow. Amazing bass. So many rattles and vibrations to fix now. The car sounds so full bodied and nice, honestly I think better than the Celica except the staging isn't as good since the tweets are down in the doors on the Mazda because coax speakers. I did good. I am happy. I dislike the car much less now, just having good sounds makes my day so much better.

Nice! I've wondered about the Tang Band speakers after seeing them on Parts Express. Good to hear that they sounds pretty good to you - might be something I should look into down the road. Commute really sucks, if the tunes don't sound very good - especially if you spend a good amount of day just commuting back and forth to work.

I fixed about 80% of the rattles and buzzes pretty quickly, I'll go through and do a good job later when the weather stays nicer. It's good enough for now.

 

 

Now I'm ordering up some 205/50-16 Conti DWS for some 16x7 04 Mazda 6 wheels I got to fit the 03-05 Mazda 6 front brakes that are going on it. The rotors are MUCH thicker and about 20-25% bigger around, the pads are about 30% larger, the caliper bore is slightly larger but the forums say no problems with it. Once the fronts are done, wheels/tires are on it'll be road trip ready if I want to drive anywhere and not eat up the sticky summer tires on the Celica. I have all the parts except for the rear brake adjusters to rebuild the rear drum brakes. I've decided that the rear disc swap is going to be too much time and trouble no matter how much I'd love to have rear disc. If I didn't need to change the whole knuckle with bolts that are about 10 inches long that run through multiple bushings I'd consider it. Or if the car wasn't from the salt belt I'd consider it. I just don't think they'll come loose without a ton of fighting so I'll rebuild the drum brakes with new hardware, springs, shoes, wheel cylinders, and adjusters and see how it is. I think it'll be fine.

 

 

 

I do need to pull and clean up one drum to paint black, one that I had painted was defect (warped bad for no reason) so I had to get a quick replacement and no time to paint it. With wheels on I'd like a nice black brake drum back there. Eventually. Asthetics can wait, I can do that at home on some weekend.

Sounds like that Mazda is coming around nicely.

 

Yeah, I'm waiting for good weather and some free time to play around with cars. trying to get my son involved in some simple wrenching around the car, as it will eventually be his. That leaves me with filling that spot with a potential summer / good weather car / possible auto-x project car.

It is. I'll be happy when I can just drive it. I need to do an alternator and axle, but first rebuild the rear brakes. Once the weather stays nice I'll leave it at the shop, take the train home, walk from the train (3 miles, no sweat), and just drive the Celica till I'm done. I can do one side then the other over a couple lunches or something during a week. The shoes, hardware, and wheel cylinders are original, the adjusters have stopped working and the brakes are far out of adjustment. I need to track down some brake adjusters.
