Hey peoples! I've already learn't a bit going through some of the replys you have all written, your all doing an awesome job!
This is my problem, I own a 98 Subaru Forester, I have a pioneer deck with one rca left and right out.
I want to run two amps; a boss audio BA-2900 4 channel bridgable rated at 60W RMS x 4; and a Alpine monoblock MRP-650 400W RMS @ 4 ohms, 600W RMS @ 2 ohms.
I'm running a 6 1/2' Alpine splits 70W RMS, two Alpine 4' 30W RMS on the rear doors. Also a pair of MTX subs in a box in the rear. I'm not 100% sure what RMS they are but I'm sure i dont need a bigger amp, I might blow the rear door off!!!! lol.
I need to piggy back the two amps ( boss to alpine), but the boss has two sets of in plugs one set on the rear side channel and one on the front side, ( the outs are on the front input side). I'm not sure if the amp needs two sets of rca in's or not?
Basiclly what I want to know is, can i piggy back to two amps, how to do it, can i power the 4' speakers, or can i bridge the two channels to one side and two the other side, just for the front? and how many amps will i be pulling for wireing, I brought a kit, just want to make sure it's enough before i go wireing through my car, and also what to start my gain settings at ..80?
Thanks heaps guys, i hope you can make somthing out of my ramblings! Cheers Mick from Melb.

This is a very old model amp. (Circa 1996 - 2005?)
OK, where to start... If this amp has 2 pair of RCA input jacks and the HU only has 1 pair of RCA's, using "Y" splitter cables at the amp input stage will give you 4 inputs, but no HU fade control at the HU. That's fine if you want to bridge this amp down to 2 channels and power the Alpine splits with this amp only and use the HU amps to power your rear 4" speakers. (Recommend a Highpass Capacitor type filter to block lows to the 4" speakers) Or, use amp as a 4 channel and set the HPF for the rear speakers above 200 Hz.
Since this Boss amp does have RCA outputs, you can use these to feed the Alpine sub amp as well.
There are several other options to consider here as well. It just depends on how much work you wish to put into this project and the knowledge base you have gathered so far. If you have good experience with wiring and understand integration hardware well, there are several other options at your disposal.
Q's for you:
1. This Boss BA-2900, what is the fuse rating for this amp? (2x 20A's, 2 x 25A's ect.)
2. Do you have the manuals for these amps?
3. What is the model # of that Pioneer HU?
