Well, I guess the first question is....Has anyone on this board installed or know much about this amp?
Right off the top, I have been finding some conflicting information both on other forums as well as via Alpine's website and Crutchfield..
1) It states the amp is 75 x 4 @ 4 Ohms, and 300 x 1 @ 2 Ohms....but the mono channel is stable @ 300 x 1 @ 4 Ohms in "bridged mode"... <--- This is the manufacturer site..
On other forums I have read where the amp pushes the same 300 x 1 @ both 2 Ohms & 4 Ohms (Not Bridged)...Also, the product manual kind of states this as well, but its not very clear. To me that says that I am fine running my JL Audio 12W3V3-4 on this amp...I just was wondering if anyone knows this to be true...You can read this for yourself...Page (1)

2) As well, it states that 4 gauge wire is "recommended" for this install. I already have cables run in my truck that are 8 gauge and at the risk of cutting some corners, would I be fine with the 8 gauge wire, or should I really run all new 4 gauge wire? The amp will be installed under the front passenger seat so the distance to the battery would probably be no more than 10 feet I am guessing....
3) Finally...I understand the basic premise of RMS --> RMS power associations, but I currently have Infinity Reference 4002i speakers in the rear doors. They are rated @ 35W RMS @ 4 Ohms....Would I be safe still running these on one of the 75W RMS Channels coming off the amp? I know you should neither underpower or overpower a speaker...but again...Just trying to save a few bucks here considering the amp is $600 from an "authorized" dealer...
Any comments would be greatly appreciated!! Thanks..
