The problem with "hiding" amps is keeping them ventilated so that they stay cool... Not a fan of putting them in confined spaces. Class D amps run much cooler but if your talking about a 4 channel A/B amp then they tend to heat up more. It also depends on how hard you drive them as well. I've heard that the 4 channel class D amps have gotten better but still a lot of audiophiles tend to stick with the A/B for the 4 channel setup. Heat tends to shorten the life of the gear, so I try to avoid it... One thing that caught my eye though was the amount of space where the rear speakers are once you remove the panel. Would be very easy to fabricate an mdf board and mount it in that space for the amps. You'd have to set your gain and all before putting the panel back in place for sure but there is plenty of airspace in there for an amp to have decent ventilation.

 

Do we have room under one of our seats for a normal sized amp?
I briefly touched underneath a seat and there was some huge box under both.

 

Take a look under there... I wouldn't...

 

I was thinking about one of these systems. The MagnaVolt. It sounds like a great product to me.

Here is a link to a vid if your unfimiliar with the product.

 

Consider some of Rockford Fosgates new mini amps those things are pretty cool for what they are. The amount of places you could hide them goes to a whole new playing field.

Also mount your amps. I can't tell you how many troubleshoots I do and how many DIY installations are not even mounted.
