Last night I did some similar mods to my dad's 02 Carrera, father's day gift. I put the MB Quart RCE 210 in the dash, and added the Becker ipod aux input with the Belkin mod hard wired to the phone power. Quick and easy and made his basic system sound so much better. Everything is exactly the same as my 00 Boxster so it made it really easy. Now he wants a new system in his Tacoma.

Ok, so I found the problem with the dash speakers going on and off randomly. The left 4" speaker positive terminal touched the metal in the dash once in a while, I found this by accident. I redid all of my connections, had the wires all zip tied together neatly and tucked away under the dash, put the right speaker in, then the left, and as I tightened the 1st screw, the sound went out. It was then that I saw the terminal touches part of the metal in the dash. So I covered all the terminals with electrical tape and it's working fine. On the Haes 4 channel amp, the door speakers are brown, brown with a stripe, green and green with a stripe. Next step is to replace the door speakers, probably 6 1/2" mb quarts after Andy shares his template with us, thanks Andy!

The MB's mounted easily, I only had to drill 1 hole for the 4", tweeters went right in, secured with a little epoxy. I didn't use the original wires, I used new ones, crimped and used heat srink tubing, all my connections seem to be very secure, I'll have to check if there's any pinches or broken wires. Tonight I should have some time to do some digging around. Thanks for all the suggestions.

Andy, the crossovers are inline, and secured very well, I think the problem has to be with the amp connection, that's the only place I haven't checked yet. The problem is very strange, sometimes it goes off and on with bumps in the road, sometimes it just goes off and on randomly while stopped. I can't recreate the problem in the garage yet, I've shaken and moved all the connection inside the car, so I'm hoping it's the amp wires in the trunk. You should make more of those door mounts to sell, I'm sure many people would buy them, I'd consider it.

Thanks for your suggestions, I'll check all the speaker connections again, and the amp connections. I'm almost to the point of replacing the amp and head unit with Alpine, I know it will sound better, and the ipod setup will be perfect, but I'd like to keep the stock look. Andy thanks for the info on the door speaker wire colors, I'll have to see if I can figure out from the amp wiring if they match at all. Glad your setup sounds good, that sounded like a lot of work.

Can you post a picture of how well that sub fits behind the seat? Has anyone had any issues with upgraded components turning off and on randomly? My MB Quarts in the dash keep cutting out, I thought it was the crossovers so I used other ones and it worked for a week, but yesterday and today they started cutting out randomly again. I suspect the factory amp may be overheating or can't handle the better speakers, but the amp isn't hot. I've checked all connections, can't figure this out. Just about ready to get a new 4 channel amp for the dash and rears, and an Alpine head unit for my ipod. Any thoughts?
-
Thanks Andy, I'll check the amp and see if it matches, maybe I can figure out the drivers side, unless you get to it and post the colors.

Andy, For the sub install, I ran the power and switched power from the head unit, just spliced in there. Seems to be enough to power the sub, I got a little lazy and didn't run it through the firewall to the battery. When you get to the door speakers, can you let me know what color the wires are?

To feed the Kenwood sub, I connected the PNP rear speaker kit to the stock stereo, cut into the speaker wires to add the small amp under the passenger seat, fed the rear speaker wires from the amp, cut into those wires to the Kenwood sub. The power for the rear speakers and the sub are more than enough since the front stock amp is pretty weak. I put a piece of wood under the carpet and mounted the sub upright, so it's facing the back of the seat. It's only 1 click from all the way back so no issues of losing leg room.
-
The Kenwood sub is KSC-SW1, the 2 channel amp was an old Panasonic I had from a long time ago it's only about 3" x 5" x 1.5" and fit easily under the passenger seat. That little old amp is actually better than the factory amp, I have the gains turned almost all the way down to match the front components. The components for the dash were MB Quart RCE210 they dropped right in with very little modification. So does anyone know about the wiring for the 4x40 haes amp?
-
I either want to block the low frequency since they bottom out at higher volumes, or disconnect them. The kenwood sub has much better bass so I don't really need the door speakers anymore. The rest of the speakers have crossovers so just the door speakers distort from the bass.
-
I added the PNP rear speaker kit and a small 30w 2 channel amp which fit under the passenger seat. Changed out the front dash to MB Quart 4" and 3/4" components, left the door speakers stock, going to put bass blockers on them since I added the small kenwood powered sub which fit behind the passenger seat with only sacrificing about 2" of legroom. One question I have, does anyone have a wiring diagram for the Haes 4x40 amp, I want to put the bass blockers on the door speakers without opening up the door panels.
