Installer recommendations in LA

[Blue55]

My 135 is being re-delivered pretty soon. I'm looking to at a pair of SWS-8 subs. I've had pretty mixed results with installers on previous cars in LA. Can anyone suggest someone they've had good luck with who knows what they're doing, won't mess up my car, and doesn't overcharge.

My install should be pretty straightforward. I want to swap out the stock subs with a pair of SWS-8s. I ordered the premium audio option with iDrive. I don't plan on upgrading any of the other speakers.

I have an existing Alpine amp from my current car that's driving a bazooka tube I'd like to keep since it's been very reliable and has enough punch for me.

What else do I need besides an amp? I'm looking to keep the cost down since my car is a lease.

Thanks,
