What would be the optimal way to replace the stock HU and amp, while retaining functionality of all 10 speakers in an 02 TA?

Really, I need all 10 speakers to run off of the amp(s). I plan on doing the android tablet install that was done in the C6 in another thread. I also plan on adding either a 10" or 12" sub (suggestions?) in a stealth box which I assume I would power with a separate amp.

I'll be using stock speakers in all factory locations with the exception of 6.5" bazookas in the sails because they came out of my old f-body.

Then why on earth would you want to replace the factory amp? The factory speakers are designed for certain positions in the car because the Monsoon amp filters the signal to certain output channels. Retaining the factory speaker configuration without the amp would require at least two replacement amps to provide eight channels of output - four channels of low pass filtered signal to the sail panel subs and another four channels of full-range signal to the door and hatch mids.

Replace the head unit first for the most noticeable upgrade, then replace the factory speakers for an additional improvement. Replace the Monsoon amp only if you decide to do a complete rework of the entire system with aftermarket equipment - including rewiring everything.

Personally... the Monsoon system is really an all or nothing type system. Either keep it all (Maybe a headunit swap only) or ditch the whole thing and go completely aftermarket. The speaker impedance's are all funky (non standard) and the amp has some crazy crossover/filtering schemes in it.

If you want to replace the headunit with a tablet, get a 25+watt x 4 mini amp. The Monsoon amp is designed to use the speaker-level outputs of a headunit (not the RCA outputs). The tablet's headphone output won't provide enough power which is why you need the mini-amp.

Connect the headphone output of the tablet (or preferably line out if there is one to get cleaner unamplified signal) to the RCA input of the mini-amp and connect the speaker-level output of the mini-amp to the car's radio harness using a Metra or Scrosche adapter.

There have been a couple threads on this a while back. Do a search and you'll find more info.

Just because I wasn't sure how to get a speaker level output from the tablet to the amp. I wasn't aware of the above mentioned method. Thanks for the help guys!

NEW QUESTION: If I run the tablet's headphone out into a mini amp, how will controlling the volume from the tablet affect the sound quality? Will it be incredibly distorted at higher volumes?

I might just ditch the entire system and start over to make this work.

VIP1

That is why I suggested using the line-out of the tablet instead of the headphone output.

Even if you ditch the Monsoon system, you will have the same problem.

kjcmusic17

That's what I though. I'm pretty sure they don't have a line out. How come the C6 install doesn't have that problem? He ran from the headphone out to the amp?

VIP1

To my knowledge, the C6 stereo setup uses lower level outputs (like RCA) instead of high-level outputs (like speaker outputs).

But I'm not completely certain on the C6 stereo setup so you'll have to ask someone that knows more about it.

kjcmusic17

So an option would to be to find an amp that can accept low level inputs and use that instead.

You have two options:
1) mini-amp to keep monsoon system
2) replace monsoon system

Monsoon System- Get rid of it UNLESS you want to keep the factory originality in the car.

I am using ROCKFORD FOSGATE PBR300x4 (bought from Double D mods),
its a 300 watts RMS 4 ch amp.

I connect my Nexus 7 to Amp with an 3.5mm stereo to RCA cable that runs to the amp.
New wiring was installed for my Alpine Components in the doors are Coaxial in sail panels.

Pics of this?!

Sorry - I don't have any pics of the amp & speaker install (that is standard like any other).
I didn't modify my bezel and mount the tablet in dash yet.

kjcmusic17

I was just interested in the tablet and bezel.

Anyone have a link to said 4x25+W mini Amp? I'm having trouble finding one that will match up with the adapter that goes to the Monsoon amp. Maybe I'm just dumb. I searched too. Didn't find much

I don't know that you need that much power. You're not driving anything. You just need more gain. How much, I'm not sure...

Look up "HTD LGB-1". There was another RCA to RCA, low to high powered little amp on fleabay but the link to tech was slow at work, I got frustrated, and now I can't find it. I'll see if I can find it in the morning.

Capricio

Search for: "Pre-Amp RCA Input / Output Line Driver Signal Amplifier" on ebay.

kjcmusic17

Correct me if I'm wrong, but I can't use a Metra wiring adapter to go from that thing, to the Monsoon unit, which is what I need to do.

VIP1

Why not? The Metra adapter is the stock connector on one side and cut wires on the other. Just use the wires you need and leave the others disconnected (better idea would be to remove the unused wires from the adapter).
