OK, so right now im driving an 07 g35 sedan with bose system and i had a 12" kicker cvr running at 200 watts from a crappy amp that keeps cutting out if i put the volume high. So i have two questions:
1. Has anyone else had problems with the bose system that when you put the volume high, and then lower it again to the same position as before, the volume seems a lot lower than it did before you put it high? i have this problem all the time, esp. when i go above 3/4 the volume counter, the sound just seems to drop a lot. has anyone else had this problem? what to do?

2. I want a better system and my big bro has an old 15" kicker l7 solobaric lying around and i was thinking to stick it in my car. Im about to get an alpine mrp m1000 amp that should push it too 1000 watts rms for a good price brand new ($145). Would this system be good? Would i need anything else to supplement this upgrade? (ie. better battery, capacitor....etc?)

thanks for reading!

 

I had 2 kick solobaric 10" subs in my 03 Sedan with Bose... It worked great for a while but I eventually switched to aftermarket navi, speakers and amps.

I ran the same sub (only 1 10" solobaric) in my 05 sedan without bose (basic radio) and it always functioned fine. I never noticed any level problems.

If your SVC (or whatever its called on 07's) turned on?

 

what is an SVC? Sorry im a newb lol

 

i'm not sure exactly what it stands for but it's speed sensitive volume control. Usually it has 3 settings Off-Low-High. It's designed to make the volume louder as your speed increases and then lower it again as your slow down or come to a stop.

 

yes it is on because most of the time i drive fast so i thought hey maybe itll be louder but i noticed the same phenomena happened with the speed sensitive control off

 

where's the gain set at on your sub amp?

 

it is taped into the bose system so i can control the bass from the main audio control like normal

 

your issue could be a bad ground....
