Amp purchase

Amp Purchase

So with the replacement of the stock dash and deck speakers, I decided to replace the amp. This was a bit tricky because of the nature of the Saab audio system, but I finally figured it out.

I purchased a JL Audio a6450 (6ch x 45w @4ohm RMS amp) that allows me to do exactly what I need. I will be passing ch 1/2 to the dash speakers on a high pass filter, ch 3/4 to the rear deck with a high pass and then using the combined signals (pre-high pass) to send to ch5/6 where I will most likely sum them and send them to the 6.5" door speakers as a mono channel with a low-pass.

Door Speakers

I am going to replace the 2ohm door 6.5" speakers with some 4ohm 6/5" mid-bass drivers. I am looking at the Phoenix Gold ti-6 which are supposedly decent speakers and affordable ($140US for the pair).

Mounting the amp

The a6450 will be mounted in a false floor in my trunk. I haven't decided if this floor is going to be full floor or only half and have a 'step up'. The only reason for this is because I would like to keep access to the spare tire.

I plan on leaving a second amp 'chamber' for an additional sub amp that will power a single 8"or 10" JL w3v3. I haven't decided on the amp or sub yet. I think I will use a JL a1400 (500w class D) or a JL a1200 (300w class A/B).

Sub

The sub will be mounted in a custom fiberglass enclosure on the passenger side of the trunk. There is currently a small area which is apparently for golf clubs cut out in the side, which if I take off the panel, leaves a nice sized chamber for a single sub. I will hopefully render both the floor and the sub enclosure soon
