Finalizing VW Golf Install Specs

Phoenixcolt · Post by **Phoenixcolt** » Thu Feb 01, 2007 12:17 pm

Clarion DXZ955MC headunit, which I love the specs on and owned the step down model a while ago.

RSd65 comp set for the front. Stock locations. I will be running 2 channels of an rsd500.4 to the tweeters and 2 channels to the mids. High pass the tweets at like 1000 or so, low pass the mids at 1000 or so on the amp(is 1000 ok or better at diff. freq.?). Dump the passive. I will run high pass out of my deck at 40 for the mids that I will be able to control independently from the tweets with the deck I am using so the mids will be bandpassed between 1000 and 40. I will also be able to time align the tweets and mids independently which is great using this config. I was thinking of adjusting the tweeters to like 10 watts, should I do more? I don't want to blow them. The mids I will adjust to the 78 or so watts each that the 2 channels they will be run off of can put out.

RSd12 sub. 4ohm svc. Bridged off of a Ti600.2.

What do I need to run for power wire, will 4 gauge suffice or do I need 1/0 for these two amps? I am guessing 4 will suffice but the 600.2 will be pulling a lot of power so I am not sure what is reccomended.

Stock 90 amp alternator. To avoid crazily dimming lights, how big of a capacitor should I pick up? I know that 1 farad per 1000watts is recommended but not necessarilly adequate in most cases. The 600 is going to be a class a/b amp running in mono capable of pulling up to 60 amps on it's own and I am not sure on the RSd500.4. Will 5 or so farads help or be overkill or not enough? I just want to make sure I don't destroy the alternator with all this.

Would it be better to put an extra battery in instead of a capacitor?

Thanks in advance.

1/0 or even 2gague would be fine, or you could even run a dedicated 4 gauge for both. a single 4 gauge will not be sufficient at all.

don't let the 500.4 fool you. it is 85x4 at CES2006 standards. if they rated that amp in '05 it would probably be called 1000.4. it needs its own 4 gauge for sure.

Good to know. How about my power supply though? Extra Battery, or just cap? If cap, how large?

Post by **Bfowler** » Thu Feb 01, 2007 1:25 pm

i wouldn't worry about either, see how your system handles it as is, and if it needs more oomf, start worrying about extra batteries or new alternators

Well I just know how these a/b amps eat power up. I used to run a ti1000.2 at 1 to 2 ohms with 2 ti400.2s and later a ti1200.1 at 2 ohms with 2 ti400.2s and i had 2 batteries and a 15 farad powercore. Then after a while I was forced to upgrade to a 200 amp alternator that i still have in my Colt. I know the setup for the VW will only be a ti600.2 and an rsd500.4 but I am definitely afraid the stock alt. won't keep up.

that's probably true. what i was getting at was don't wast your money on a cap and/or extra battery, just go straight for the alternator.

Upgraded alternator is great but usually ridiculously overpriced. Know of anyone who sells one for less than $500?

dont bother youll be fine

with normal music i doubt youll peak over 300-400rms watts

Cross tweets/mids in the 3200 range.

Phoenixcolt · Post by **Phoenixcolt** » Fri Feb 02, 2007 7:33 am

You all think I should just use all the deck crossovers instead of the amp crossovers since I can manipulate everything independently? It would be easier to get exactly 3200 hz than guessing where 3200 hz lies on the amp.

I was just looking at the RSd500.4 crossover frequencies. They only go from 40 to 400 and there is no x10 button like the Ti had. Why is that? I guess I will have to use all deck crossovers unless I am missing something. Am I missing anything???

Use the deck XO's, you are correct the RSd has squat for features beyond the basics that everybody has.

Post by **Bfowler** » Mon Feb 05, 2007 10:49 am

you could just keep the RSD passive crossover and duel bridge the 500.4 to make up for the power loss of the crossover

That would be a good idea but I will be using the decks time alignment, and since the tweets are on the dash and the mids are going to be in the doors, I need to be able to time align them seperately. Otherwise it would hurt the sq.

My plan was to be able to run the low level speaker outputs to the coaxes and stock tweets in the back for my passengers and I would be able to turn them off thru this units amp canceller when I was alone again. The way I will have to run the xovers since I can't do a lot from the 500.4 makes it a little more difficult. Now I will have to run speaker level outputs to the rear tweets rear mids front tweets front mids individually. No biggy but:

Does anyone know what colors the tweeter wires and mid wires will be behind the aftermarket wiring harness?

I found a wiring diagram for the front tweets and mids but it was for a 95 or 96 and it was only for the fronts. This car has rear tweets.

I have an RSd 500.4 on the way and a Ti600.2 for the sub but I am still considering using a single amp to power the whole system.

What is the potential current draw on a Ti900.7. I know the 1200.1 was 120 amps, is this the same? Can't get the manuals on PG any more!! I am considering picking a 900.7 up. If I did this, I would run 4 channels of the amp active to the mids and tweets and run the sub out at bridged 2 ohm.

Stock 90 amp alt, stock battery at the moment. Would I need to upgrade the alt or add a batt. or cap with a 900.7?

Was tantrum revised xs? I am also still looking at the xs6600 as a possibility for a single amp system but I really want that 900. Is the xs6600 considered a sweet amp or a mediocre one overall?

Thanks.

its pretty average. 50x4 for the four channel and 75x(300 bridged) for the sub output.

tantrum was/is a revised XS amp

Thanks for the manuals. 80 amp draw, not too bad. I am thinking it would be a similar draw running two amps vs 1 900.7.

How is the sound quality on the xs 6600? If it is average, what makes the 900.7 above average? Is it all of the technological advances between the time those 2 series were made?

Phoenixcolt · Post by **Phoenixcolt** » Wed Feb 07, 2007 11:24 pm

Got a hold of a 900.7. You guys think 2 gauge would be enough to run from the battery for the one amp?

Amp manual reads 4 gauge mandatory. If you're running it directly to the amp it meets the recommendations per PG.

Phoenixcolt · Post by **Phoenixcolt** » Wed Feb 07, 2007 11:37 pm

At least 4 is mandatory. I don't want to go bigger than 4 but does anyone that has used this recommend I go higher?

Post by **stipud** » Thu Feb 08, 2007 8:10 am

I noticed a huge difference when I went from a single run of 4, to a run of 0, with a 2 foot piece of 4 gauge before the amp. 2 gauge should be perfect... the terminals should be able to accept the wire directly.

Phoenixcolt · Post by **Phoenixcolt** » Thu Feb 08, 2007 9:21 am

Cool, I was thinking 2 would work.

Phoenixcolt · Post by **Phoenixcolt** » Sun Feb 18, 2007 11:07 pm

I am thinking about trying to glass something like this behind my rear seatback in my Golf.

You guys think I would be better off doing just 1 sub in one of those corners?

Would 2 angled this way lead to a lot of cancellation?

I would like to do 2 10s like this or 1 12 in 1 corner.

I know it isn't a great drawing but I wanted to show you something like I am invisioning : ).

from your other pics, it looks like you are a pretty handy installer....what about something like this?
