Im confused.
If you are running a high power 55 Amp alternator at full power at 14 volts, thats 770 watts. Even if you ignore efficiency losses, if you are running your amp beyond that, then youll be sucking the additional needed power from the battery. Even if you are running the LiFe 6 amp-hour battery, you/dont have much time before you run out of power...
So, unless you are just riding a mile or two, I dont see how you can cruise any distance if your 1,000 watt amp is really putting out 1,000 watts...or even 700....or 500 if you are running any other accessories.

Good point. The power is there to deliver when needed, such as some hard bass, but on the average would need to be much lower.

Unless your gains are tuned for a target voltage, I do not see none left on table. Which is a good thing!
EX
Ch1 Fairing wired parallel 2ohm load split 250 or 125 per speaker
Ch2 Lowers wired parallel 2 ohm load split 250 or 125 per speaker
Ch3/4 bridged bags wired parallel 4 ohm load split 500 or 250 per speaker

My amp is 4 x 250W @ 4 ohm or 2 ohm. Many have said this is good for an 8 speaker set up but then I would ask questions and the answers would come back not a good idea to parallel speakers with different sensitivity or placing 6x9 and 6.5" in parallel is a bad idea because your filters need to be set different to be effective. Then this thread happened and it made sense. 4 channels = 4 input RCA = 4 opportunities to set levels and filters. I was trapped thinking solely about front and rear with a left and right channel. MONO gives me the ability to put 125W to each speaker and tune each set of 2 to the correct frequency range and output level. Thus I have not left any power on the table and balanced my system through proper tuning. If I have this philosophy wrong please correct me.

If u have the watts to parallel & a DSP, wire them to a specific channel and tune away for that specific channel unlinked.
Caution, some DSPs allow u to unlink the tune with the exception of the crossovers & slopes. Plan & shop accordingly.

One day I might grow up to be big and strong! At that time I will look back on the journey and be glad all of my coaches helped train me! Thanks for all the help to all the members of this community! Seek to understand with a questioning attitude and you will become an effective individual.
So when I purchase a DSP It seems the DSI-2 may be the best for this application for my set up. After doing a little more research it appears to have the ability to tune each channel independently for slope, filters, and gains. I believe the DSR-1 is only capable of un-linking pairs of channels to set gains independently. I really would rather purchase one DSP, instead of two due to making the wrong choice. So in the opinion of those vastly more experienced than myself, could you please share some recommendations for a dsp. I do not want to leave a bunch on the table.
