Anyone have thoughts on MB Quartz 4-channel amps? Figured I'd ask here than to start a new thread.

 

alpines have differential balance imputs according to a guy on bimmerfest. im looking into those. i havent found anything on mb quarts though.

 

Sounds fine to me, but not being able to look at it

Just check the screws holding the thing together closely for signs of the unit being opened and messed with.

 

got it thnx. ill let you know how long my stock sub can take the power b4 it "blose"

 

I'm going to be using a Rockford Fosgate T1000-bdCP.

edit: I think this post was supposed to go to another thread... sorry..

 

TT are you doin stock setup like me? if not, what are you gonna run? after hrs of research im open to all ideas at this point.
I'll prolly just go with all new speakers and sub like wrathernaut suggested sooner rather than later.

 

dumb question. i just looked at your equipment. you are way past the stock arena

 

you know how when you go to costco for just for toilet paper and you walk out of there with a big screen tv ? thats how i feel with this audio stuff. doing your homework is good but you quickly discover stock is not good enough. my wife thinks I'm obsessed haha. but I love my car and plan to keep it for a while. this may sound snobby but I won't let anybody touch it. when It was under warranty I would put a "do not wash"sign on the dash and now i do all the maintenance with help from the forum. thnx guys

 

All I can say is that the more work I do the more my car means to me. Although I've definitely let friends drive it here and there. Haha.

 

I completely agree. whenever I do a full detail,engine included ,it feels like a new car to me and I baby it just a little more.haha it's weird. my brother who races alfa romeos,can't wait to get his hands on my car but no way. whenever I'm in the car with him it's 1 hand on the dash and another on the door handle .imagine what it would be like without me in the car. he most definitely would have it sideways almost immediately. haha

 

please explain what is an rca splitter and how would i connect this to my existing speaker wire.
can you please give me a quick rundown of what wire goes to what?.thnx

 

It's an RCA cable on one end and 2 RCA cables on the other. Like a "Y."

A 4 channel amp requires 2 pairs of RCAs and you'll only have 1 pair. A splitter will give you 2 pairs.

 

thanx Top Teke, sorry for asking such dumb questions, but i thought the bose system has no rca. can you clarify. thanks TT

 

A bit off topic, but can this concept of differential balanced amp idea be explained further? Are they simply using a common ground for multiple channels instead of individual +/- for each?

 

No problem. You are correct, it does not have RCA outs. You would need to use a line level converter. This sticky explains the rest of the details on how to add a sub/amp while keeping the stock Bose HU.

The physical input/output is the same. Here's a rundown on balanced audio from Wikipedia.
