What are the options for upgrading/changing the receiver and speakers for the Allante? What receivers can fit in the dash? What speakers will fit this car?
Thanks!

Put the top down. Leave the radio off. Problem solved.

I probably spent more than $500 last year getting the stock radio (not CD) working again with parts from AllanteSource and labor for my mechanic. I was hoping to use the car as a summer daily driver, but it will probably stay as a weekend only car.

Easiest upgrade is to replace each 25 watt amp in each enclosure with a 50 watt from a 91 or 92 Allante.

We do have a high output upgrade to the original 1989/90 amps that probably surpasses the volume of the 50 watt units in the '91/'92. We only do them by special order and the cost is an extra $30 per amp ($120 versus $90). You'd have to do all 4 of them or the volume would be unbalanced.
