I just bought a 12" Pioneer sub TS-W309D2 from Best Buy on sale for $40 thinking it was a good deal (was it? lol). it's a 400w rms 2ohms sub and I'm having a hard time deciding which amp to get. I understand adding just a sub, I should get a mono amp and from my noobish research, I've come up with two amps to choose from: the Kenwood KAC-8105D and the Alpine MRP-M500. both amps are similar in specs and I don't know which to choose or which one is better. are these even the right amps for me? are there any other amps I should be looking at? I'm just looking for a reasonably priced amp to properly handle the Pioneer. This will be connecting to my '12 Accord SE. any help would be appreciated, thanks

I had the little brother from that Alpine (MRP-M300) Same Size tough! It is Powerful like crazy for that size! Only CON is, It doesnt have enough Customization but alot of Presets..

You cant go Wront with Either of Those....

The MRP-500 is rated at 500rms of juice, but with wiring/other power loss you might actually be looking at 400rms so it should work out well. If you're afraid of overdriving the sub you won't be too upset with the MRP-300 as stated above, alpine amp is the way to go though.

the specs are a little confusing on this sub. it looks like its a dual 2ohm voice coil sub, that means it will wire to 1ohm in parallel and 4ohm in series, and neither one of those amps mention a one ohm stability and are around 300w in 4ohm which is honestly going to be better for that sub anyway, as i dont know that a 40 dollar sub would do a true 400w for too reliably for too long. so i would say you need to find a 1ohm stable amp of some sort. dont mean to be a downer, and i hope im wrong. it will sound ok and your probly realistically looking at 250w daily.

Werd. Which still isn't that bad for this setup.

no really not at all, i think it will actually sound nice and full rather than overly thumpy at that wattage, and the upside is at 250/300 ish you wouldnt really have to worry much about blowing the sub, my only real concern for the poster was not to ruin his amp of choice...same amps but what ever the 1ohm version might be (for bigger bass) or just wire for the 4ohm.

It's always best to have a amp that is capable of making more power than needed. That way you can set the gains correctly to get the power you want and need. Set them correctly not just eh thats good, get a dmm and research and find the guide that tells how to do so. Unless you have a o scope(but you prob don't know what this is, hell I doubt many here know what that is)
