I recently changed out my stock bose HU with aftermarket HU and stock bose amp and speakers. Now for some reason I lost some of the bass that I use to have with my stock HU. My question is can I add a sub and use an aftermarket amp to pw it and still keep the stock speakers and bose amp? I was told that this setup would cancel each other out and sound crappy. Anyone have this setup and how does it sound?

As of now I feel the stock speakers sound better and louder but the base is worst with the aftermarket HU. Anyone have this problem?

 

What HU do you have? The electronic crossover may be active, which would cut bass from your front speakers

If your new HU has RCA outputs, you can add an amp and sub and send the signal from the HU to the amp with an RCA cable.

The Bose amp is the weak link in the system, though, so since you are adding an amp anyway, why not get a 5 channel amp to completely bypass the Bose amp and power a sub and the interior speakers. I used a JL 500/5 to do that.

 

if u do it your way wont I just blow out my stock speakers faster that way?

I'm running the kenwood 8019 and I do get base but not deep? The base is there as the volume increases but it sounds like bad base, lol.

 

I have an Alpine head unit that feeds the BOSE amp and speakers, and I use the SUB out on my Alpine to an AMP to a sub in a 4080. I love the sound, but I do have Kappa door speakers going in soon o make it better.

 

Have you adjusted the bass settings on the Kenwood unit itself? I had the Kenwood 8017 and just recently swapped it out for an Alpine IVA w200. The difference is night and day with the 2.

 

Not if you adjust the gains properly.

You're going to want to replace the stock speakers anyway.

 

u got any pix of your setup in the trunk?


Also, if i was to keep the stock bose amp, can I just get aftermarket 2ohm speakers or will 4ohm speakers be better?

 

If you keep the Bose amp, you need 2 ohm speakers to connect to it.
