The local shop is selling the older alpie type r 12s in the ported alpine boxes for only $119. I might pick one up but I need some ideas on cheap but good amps because I don't have very much money to spend on car audio right now. Btw, it comes with a 4 ohm DVC version of the type R so I will need a mono amp. -------------

Concept CA525M amp is what I used on the last one and wow man. The next amp I used was the new Scosche EFX amp and it layed the smackdown as well. Definitely worth looking into.

Like around $150 at most.  If I do buy it it anyways... I don't know if there is an amp that puts out 400 watts continuous for that little amount of money. I saw an Infinity Reference amp on sounddomain.com that was rated for 300 watts continuous at 2 ohms. Anyone have any experience with these amps? Any other suggestions. -------------

I would stay away from the infinity amps. I haven't heard and good coments on them at all. Why not just look on E-Bay? I just bought a MTX refurbished 801D Sealed in the box right from MTX for $160 and the Test sheet showed 582 watts max at 2ohm at 12v. The Damn thing pounds like hell. Here is a link to one that I just found and from a reputable seller to boot. https://cgi.ebay.com/dll?ViewItem&category=64573&item=5769616190&rd=1 BTW: I bought the 801 that I have from these guy's. Good customer service. Chris ------------- Alpine CDA-9833 HU

Alpine has a small mono amp that does a decent job at powering a single type R. I believe the model is MRD-M350. It is 350-400w RMS and retails for $199. You could probably find it used for under $150 though.

The new MRD-M605 is $215 on flea bay, same price as the M350 . No worries about their quality going down hill, my brother bought the new M605 and its still an amazeing amp.

my brother has a type r 12 and has a rockford fosgate on it. i think it's 400 rms and it hits hard, but doesn't extend the sub all the way which would prevent you from damaging it.

I just connected it to a home reciever to listen to for now and it sounds great! It got pretty loud too even though the amp's output is only around 100 watts a channel or so. Racer 427, where have you heard bad things about the Infinity amps? All I've heard about them is good. I actually might buy the MRD-M305, but the Infinity amp is only $134 on sounddomain.com. -------------

Actually 2 friends of mine both had bad experiences with infintity amps. Not so sure if they were the new model's or not. The other thing that I don't like, the power rating that you see on cardomain are dynamic not rms. Chris ------------- Alpine CDA-9833 HU

I just looked inside the port of the Alpine compound reflex box. It's weird... It has slot port that goes the depth of the enclosure (it's on the left side of the box) and then two circular ports connect the slot port to the main part of the box (where the actual subwoofer is). Does anyone know what this design would be called? Here is a drawing: 
It looks similar to this sixth order box, except the woofer is mounted on front instead of inside the box.

Would an Alpine MRP-M350 be a good amp? I might buy it off of ebay, unless I can get the local dealer to bring down the price a little.

I have it, and it gets loud as hell. Sounds like more than 1 sub. Yeh it has two circular ports about 3-4 inches that lead to the outer rectangular port. Is the m350, 350 watts?

Sorry I should have gave a link to it. https://www.crutchfield.com/S-dICvlAHP2Ea/cgi-bin/ProdView.asp?g=130&I=500MRPM350 And it supposedly does 350 watts continuous at 2 ohms. -------------

It would sound good, but even more watts would be even better! I have 550 going to mine and it sounds great. ------------- Volkswagen Golf
