E53 Amp Upgrade Question
 

Alright experts, please help me out. I've spent the last 3 hours searching this sub-forum for an answer, no success (could be my density on the subject matter), so here goes.

I have a 2006 E53 X5, non-dsp, non navi, but with the HIFI 10 speaker set up and amp. Upgraded my factory speakers to the BSW kit because a couple of the stock midbass had blown. Overall I'm happy with the sound, much better than the factory setup. Come to find out no sound is coming from the right side midbass (new speaker). Figure an amp channel is blown and wanted to upgrade my amp anyhow, so I need suggestions.

I'm not interested in replacing it with another factory amp and I'm also not willing to wait for the BSW solution (seems like it has been in development for 3 or more years?), so what would everyone suggest to replace the stock amp?

I know next to nothing about audio and need some help, thanks in advance!

Forgot to mention that I have no motivation to do anything to the head unit, either. I will be keeping the MID.

Unfortunately there is no easy solution to do what you are looking for, as most will require extensive custom wiring. We typically recommend just sourcing another factory amp!

Figured out a solution and it works great. Running 2 Alpine KTP-445U 4 channel amps now. Apparently the dash mid and tweeter were on the same channel, so it is connected as such: Left Dash Mid/Tweeter Channel 1, Right Dash Mid/Tweeter Channel 2, Left Front Midbass Channel 3, Right Front Midbass Channel 4. The second amp is: Left Rear Mid Channel 1, Right Rear Mid Channel 2, Left Rear Midbass Channel 3, and Right Rear Midbass Channel 4.

Sounds great with the new BSW Stage 1 kit!

Glad to hear you got it all worked out and that you are enjoying your Stage 1!

I'd love more info on how you wired that up. I wanna get best sound without adding a sub and u seem to have exactly the set up I'm looking for! Pics would help too
