View Full Version : Alpine INA-W900BT Questions

12-19-2010, 01:56 PM
I just bought one and I'll be putting into the STI here in a few days. This is an upgrade over my old Avic 900BT.

1. I purchased the SIR-ALP01T unit for the sirius connection... What difference is this over the KCA-SC100 + SCC1 combination? The SIRALP01T is going for as little as 30 dollars on Ebay (marked down from 299.99 from shop.sirius.com!?). Both units use the Ai-Net connection so I'm at a loss to which one is better and why.

2. I'm debating on what amp to buy. MRP-F300 or the KTP-F445. I'd like to keep the install clean and hidden and I think the KTP-F445 will provide enough power to get the job done.

any other thoughts?

What are your system goals? The F300 will be cleaner and give you better headroom than the 445 Power-pack. A bigger, dedicated amplifier will always give you better performance. I've used a few Power-packs and they're a nice piece, just powerful enough to drive Type-R components. If you're using stock, Type-S, and alike speakers, the 445 Power-pack will suffice.

Can't help you much with the Sirius question. It looks like the SIR ALP1 is a simpler install through the Ai-Net bus. I still use a docking station so I can take my Sirius tuner in the house too. Good luck.
