Upgrading sound system and keeping stock HU
#46
Hi people, I read a lot of these post and i want to add an amp and 2 10's to my car. Now i have a stock 07 coup and i want to keep my HU but i want to add a amp and speaker. I read that the car comes with an amp in the trunk under the rear support. So do i use the amp that is in the car as a pre-amp to the amp?
Ok let me make this simple..
1: What do i need to add 2 10's or 2 12's or 1 speaker to my car with keeping the stock HU and why do the speakers face the rear of the car instead where i would be. I'm not in the trunk. hehehe
2: i want to use a amp (aftermarket) can someone recommend one that will work great with the stock HU? and remember broke as a joke.. (meaning i don't want to spend over 200 for an amp)

Thanks for this thread
I am able to enjoy some added bass while I wait to get all my gear together for my full custom install. Presently I am running 2 JL 10W6s and 1 JL Audio 500/1 Amp running the 2 subs. This set up is overkill for the oem system, I had to turn down the gains to its lowest setting. If you are to keep the original oem system and just want to add extra bass, I would suggest running a single 10 and maybe a less powerful amp. I prefer using an amp with more power for additional headroom(cleaner sound) but hey thats me, but for the budget the latter would be a better choice for most people. I was not able to take pics at this moment but I will soon in the next few days.

Just trying to figure out a few things before taking the final step.. So far, I have a sub and box that fits in my car, new front components and a cheap amp that I had left over from my previous car. Now what I need is some way to get the signal from my stock NON-BOSE HU, to the amp. From what I've read here, I need an LOC that will convert the differential balanced signals to standard single-ended inputs. I was discussing this with my friend, and he recomended the MTX RE-Q, because he said it fixes the problem of the stock HU turning down your bass at higher volumes. However, I'm unsure if it will convert differential balanced to single-ended. I could go with an LOC that I know does this, but will this other LOC prevent the bass from being choked by the stock HU? I just don't know... The only thing I know that will do what I want, is the JL Cleansweep, but my system is very low-end, and basic, and I don't want to go with such an expensive solution, because it's overkill for my needs. Any ideas, pointers? Really confused here.

Hello all,
I am new to the forum with a G37, I have had the car almost two weeks and I am ready to overhaul the audio system. Does anyone know where I can find a schematic for the existing system or a pin out of the molex connectors that are connected to the amplifiers in the back? I would like to determine if the current system uses passive or electronic x-overs? I would like to upgrade the amps, speakers and add a sub. What is the best method. I currently have a couple real nice balanced zapco amps with the x-over. I was thinking of taking the balanced output from the head unit to the Zapco electronic x-over then running one amp for front and one for back and take the sub out to another amp. Do the current speakers have any networks on them or do they get x-over from the bose amps? any help would be appreciated. thank you Z

I have kappa 60.7CS in the front, 62.7i coax for the side fills and 692.7i coax for the rear deck.
I know the stock amp only outputs lows to the rear deck as "subs" so my coax rears ain't doing anything but bass.
What I would like to do is get a 6 channel amp like this to replace the stock:
http://www.crutchfield.com/App/Produ...nel&i=136A6450
and if I need additional bass which I think I will I can add a basslink.
My question is how do I get the 2 rear full range channel outputs from the stock HU to feed 4 of the 6 amp channels so I can get full range signal to both the rear sides and the rear deck? Can I just split the 2 into 4 or is that going to cut signal to all? And then where do I tap the basslink into?
