Hi all,

I have an Alpine MRP-F600 4/3/2 channel amp. Specs are:

100W RMS x 4 (4 ohm)
150W RMS x 4 (2 ohm)
300W RMS x 2 (bridged, 4 ohm)

I have four speakers, they are Type R components which handle 110W RMS at 4 ohm.

I have two subs, Alpine Type S 10's, they handle up to 300W RMS, dual voice coil, each coil is 4 ohm.

I think I have the wiring scheme figured out but am looking for some input as to whether or not it is the best route. Here is what I have so far.

Run the front two components in parallel through the first channel. The rear components also in parallel through the second channel. This should give each speaker 100W at 4 ohms by my calculations.

Then run each sub wired parallel (with the second voice coil connected in series) to the other 2 channels. Should give each sub 150W at 2 ohms.

I've attached a simple diagram that might be helpful in understanding my descriptions. Is this the best way to run it using this amp? This amp is capable of 1320W MAX power.

Thanks for your input!!

It will produce sound, yes. You will have no fader, no balance, basically no tuning capabilities, but it will make noise. The obvious fix is to run a monoblock, but I assume budget is a concern here...

No, budget really isn't a concern..my concern is the amount of trunk space being used. I was hoping to avoid two amps which is why I'm asking for suggestions.

I guess I could run the front components off channels 1 and 2 then the subs off 3 and 4. For rear fill I could toss a set of coaxials in there and run them off my HU.

Ideally you should just use that amp for your speakers and get another amp 2 ch or mono for your subs. That gives you the balance on the speakers and then your ratings for all your components are met. That being said if the budget is not giving for this then lets look at the connections for the 1 amp.

If you parallel the 2 front and 2 back speakers each at 4 ohm that would give you a 2 ohm to each of the first 2 channels. That would provide 150 Watt to each pair of speakers producing approx 75 Watts per speaker. Connect these to Ch 1 and Ch 2

You should not hook up the subs that way, your putting an 8 ohm load on to a 4 ohm stable amp channel. you should bridge CH 3 and 4 and then series the coils and parallel the subs to get 4 ohm load. This would then provide 300 Watts total to both your subs, which is the max you could get out of your amp.

If budget isn't a concern, run a monoblock on the subs. The Alpine MRP-M500 is a small amp that (half the size of the 600 you already have) seems to be purposefully built to drive the E and S type subs, and it will match your other amp to boot.

I know the M500 is a solid amp the problem is trunk space I was trying to avoid two amps. I guess I have no choice

Just install the amps vertically, then they dont take up nearly as much real estate in your trunk.

OP, what is the vehicle?

Dude, come meet with me somewhere today. I now live in the Calgary area and have nothing to do today on my day off (my family is not out here yet so I am still allowed to do car audio).
