Has anyone used the MTX TX6.BMW speaker upgrade? (link below) The kit comes with mid range and tweeter replacements for the front two doors and two new slim woofers for under the seats.

I have an E70 LCI 35i with the base audio... We all know it needs upgrading. I've looked at the Bavsound options and was about to pull the trigger but then came across this MTX kit. Bavsound is great but to upgrade mids, tweets and woofers its about $1000, MTX kit is around $400 with subs. Granted no upgrade for the rear doors but I'm sure I could source them separately.

Ive searched the forums but cant find info on this: Does anyone know if the speakers connections are still in the rear trunk area even with my base audio with no amplifier? Could I slap a small 4 channel amp in the rear factory trunk location easily or do I need to source speaker connections elsewhere?
