Also i already have an Alpine deck installed
SO i have a 2005 GLI mk4 with the stock Monsoon stereo system I have after market speakers for tall the doors and components. my question is since there is an amp in the back of the car do i need to replace the wires or could i just plug and play with my new one? and do any of you guys know what the specs are for the stock amp? the new one im putting in is a 250 class d alpine. and are the speakers 6-1/2 all around? has anyone had any major problems doing a sound set up in our cars.. i heard i would need a capacitor from a stereo shop state side because the car cant handle the power and it messes things up.. not sure to the extent of truth on this. let me know thanks. I have done many installs on cars and if there is one thing i have learned its that every car has its own issues. (ill never do a MR2 again!) and if anyone has a wire diagram of my GLI that would be cool thanks any other tips on the install will be welcome also
Wow, so much mis-information we will need to clear this up before moving on.
What alpine amp do you have?
I read that you have all new components for the doors. Does this include crossovers?
The 250 class d amp, is this a mono amp (model number?) and what do you plan to power with it?
If it is a mono amp, what do you plan on using to power your components?
Now on to facts.
You will never "need" a capacitor. If your charging system/wiring is up to par, you won't even need to upgrade you battery, but it is a better option that wasting money on a capacitor. It sound like you almost went backwards in planning this system out. Answer the questions above, and I will help out as much as possible.
I have two alpine type s components and a set of 6 1/2 for te back that are hertz if I remember correctly they were used with this amp( in my old car sounded great lot of power IMO) http://www.crutchfield.com/App/Mobil...MRPF250&tp=115
The comps have small little built in crossovers along the wires I believe could be wrong tho. As for subs I need to wait till I find a shop here that sells them, and good brands . And that could be a while.Thanks for the help
It would be easiest to bypass the Monsoon amp all together. To do this you would need to run RCAs from your new head unit to your alpine amp. (run an extra set for your sub amp, if your radio has 3 sets of outputs. Then you could run from the output of your amp into the crossovers for the components and then to each speaker. You can use the stock speaker wires coming from the monsoon amp, but you won't be able to use the tweeter wires, if the crossovers are attached to the mids like these:
If they are seperate crossover units it is much easier, because you can use all of the factory speakers wires.
You will have to also power the amp, and I would also run separate power for your amp as well.
I figured I would have to run new wires but I wanted to be sure. I have RCA wires. So your saying to just cut out the old amp and just use the alpine? Or maybe I could use the stock amp for the rear and then the alpine with my front and the sub after I get it. What I really want to do is eliminate the rear speakers and mount some 6/9 speakers in the rear. But that would be a pain in the ass I feel. As for the doors, is there any snags I should know about?
I been awhile but I finally ordered all my stuff. The subs came in the mail last week( 2 10" rockfords 250 rms each single 4ohm) the amp and new heady it are in the mail I got a pretty nice kenwood and the sub box and amp should be here any day. P500.2 ( Rockford ) and a vented box. I'm going to bypass the amp all together. I'm just having issues running the wires down the center if the car due to the e break and the center councle or whatever.
