Question about Alpine MRP-M450 Car Audio Amplifier

1 Answer

Not enough bass

I currently have one Alpine Type E 10" subwoofer hooked up to a Alpine MRP-M450 mono amplifier using 10 awg wiring in my '07 Honda CRV LX. I am still using a factory stock deck. (No premium sound system initially)

It sounds like I'm not getting enough bass from it at all compared to a similar setup I had in my '04 Toyota Rav4 (got stolen) which had the same sub but connected to a lower rated amp, the Alpine MRP-M350. And that sounded great with plenty of bass. The CRV is a little bigger than the Rav4 but not by much.

So what should I do in this situation? Should I get a bigger subwoofer? (I am considering a Type R Alpine 12") or bigger amp? Is it the gauge size powering the amp? (BestBuy associate said 10 awg was sufficient, I found out that online sources say that 8 awg is recommended), or is it my deck?

Any help would be greatly appreciated! Thanks!

Its prolly the deck, did you try turning the alpine's input gain controls up...

its not the wiring, if the wiring was insuficient, it would just melt...

you might also see if you could adjust the bass frequencies or crossover frequency, the crv might just have a different resonant frequency then the rav 4

I haw alpine mrp-m350 amplifier how many sub can i


Hook up the MRP-M350 to one 4-ohm sub, and you get 200 watts RMS; connect a second 4-ohm subwoofer and the power output increases to 350 watts! All that juice means that your subs won't just be loud, they'll sound clean and thumping.

How to wire 2 ohm 2 12ich alpine type r's to box terminals?


Dual 4 ohm subwoofers can only be wired @ 1 ohm, 4 ohm or 8 ohm.
2 ohm mono load is not possible.
You will need to use (1) subwoofer to get the 1000W out of the amp.
Wire both positives on one sub to + on amplifier and both - on the same sub to - on amplifier to give the amplifier a 2 Ohm load.
Add a second amplifier, or buy an amplifier that is 1 ohm mono stable.
You can wire both to the amplifier at 4 ohms 600W, but they will share the power and only see 300W ea.

You need to check the Fuse on the Power Wire and check the ground wire to see if has loosened up. Also check Power Wire as well.

Hope you see what you are your looking for! Good Luck!

When the bass cut on the speakers cut off


220 watts RMS x 1 at 4 ohms (400 watts RMS x 1 at 2 ohms)
the amplifier may be over-driven. are there red protection lights coming on the front panel? Or a loose wire - power, ground, or speaker.

MRP-M450 puts out no sound to the subs


The amplifier may be overloaded, check to see if it can handle 4 OHM loads and 2 OHM loads. if it turns off at high volume the amp may be overloaded. if so try a 8 OHM load. if it still turns off it may be an internal problem.

Have you determined if the problem is with the amplifier or the subwoofer?

 

Have you checked the wiring to make sure that there are no loose connections?
