Good deal?

Hi guys,

while looking for an amp to power my sub, a friend of mine mentioned he has an Alpine PDX M6 in storage. It looks to be in very nice condition but have yet to test it. He said he'd let me have it for $250. Is that a fair price, good price? Is there a way to test the amp short of installing it?

Thanks

Pic is not the actual amp.

Absolutely correct, it puts out 600rms. That's more than I need to run a 450rms SI BM mkV. I'm looking for a quality amp that puts out clean power in that range. Just wondering what the going price is for one of these units?

2000rms? Which amp would that be?

idk about clean vs dirty power. all I know is rated certified power and that's what this amp does. but I'll let everyone else take it from here. if you wanna lay $250 for 600rms when you can have 2000 have at it.

Well, I looked at several of those listings too. A lot of times listed stuff doesn't correspond to sold stuff, that's why I asked here. I didn't mean for you to do my homework, my apologies for making it seem that way. But thank you nonetheless.

Seems like a decent price for the Alpine. As far as pretesting your amplifier, I never did. Wire it up and turn on the stereo!!!! You could look on youtube for videos of folks testing them.

That is half the new price, which is a decent discount imo. But demand for that amp has to be low. Id offer $200. The SPL crowd wont want it and people looking to spend more for perceived quality will be looking at amps from Zapco or JL.

It is an expensive amp for only 600 watts and there is probably no chance in hell that you will hear a difference between it and many other amps that make more watts per $. But for $200, I would go for it.

There is very little info on the Zapco budget ST line, but one video featured the ST-1350XMII and it came up short in just about every test. Can I post a Youtube link here? If not, feel free to remove it:

That leaves me with little confidence in the budget ST line.

Yes, that's my impression too. So with my limited budget of about $250 for an amp, I'm looking at a Sundown SFB-1000D, the Alpine in this topic, and a D'Amore E750.1. The JL Slash series as well as the Rockfords are over budget. Any other mono amps at 1 or 4 ohms with 500rms I missed? The Rockford R2-750X pushes 500rms but only at 2ohms.

Any other reliable amps I should be looking at pushing 500rms at 1 or 4 ohms around $250?

If I remember right, that ST 1350 was a refurb unit that wasn’t authorized by Zapco. I would stay away though as well. They get super hot from what I hear and aren’t worth the cost.

For the Alpine $250 isn’t bad. Honestly, this is a more oriented SPL crowd so dollar per watt means a ton. Over at DIYMA, they will tell you to buy quality. For me, I wouldn’t spend $250 on that. If it were 1,000 RMS and up, maybe.

doesn't that thing put out 600rms? for $250 I could get an sfb that puts out 2000rms
Because the ONLY thing that matters is how many root means squared you can get, amirite?

My thoughts as well.
Zapco budget
No sense paying for the big names if you're not paying the bigger price tag for their good stuff that actually earns them their reputation. It is very likely that entry level Zapco is just something they bought out of a catalog from China. While Zapco has some top talent in their R&D, I doubt you're buying any of that in their low end lineup.

No way to test an amp without powering it up and giving it a signal to see if it works, but 200$ would be a fair price on the used Alpine.

Honorable mention for this one here. Amplab is local to me and they're good guys.
Will make 500W into 4 ohm for you and has a good bit more on tap if you wanted to upgrade subs later. I've always had good luck with Kicker amps and that's a fair price.

Sundown SFB is 200$ from their site as well, but that's way overkill for you and I would personally NOT buy a full bridge amp without a factory (or third party) warranty.

I'll check out Amplab and Kicker. Never even considered Kicker because my impression was that it was an amp for the crowd that want to rattle license plate frames and not the SQ crowd ;-)

Yeah, the full bridge technology is giving me 2nd thoughts too, but the SFB does come with a 2 year warranty. Maybe driving it at half the rated rms will prolong it's life even further, lol.

So, more checking to do. And thanks once more.
