Need Help powering 4 Fi Q18s.

[mkylexl 0]

Alright 4 Fi Q 18s. I need a amp/s to do atleast 4kw rms, sound good, wont get hot easily, and no more than $1200. I dont want to buy used anywhere, I need *WARRANTIES* so if there are any link yall can provide I will highly appreciate it. Im looking at prices currently on wooferetc.com.

For that price, w/o used or refurb it narrows it down a bit.

Do you have the subs already? Are you looking for an amp a piece, or 2 amps, or 1 amp? what are the voice coils, dual 1 or 2 ohm? That'll help narrow it down a bit more.

If you want an amp a piece, the hifonics 1206d seem good for the money, about 250-300 each. That'd be around 4kwatts.

If you want 2 I had 2 hifonics bxi2006ds that never gave me any problems (except when I tried going below 1ohm)- thats about 4kw. I'm sure there are plenty of 1kw amps you could get for a similar price, just throwing out what I had good experience with.

If you want one amp and have a local memphis dealer they told me they'd do $1200 w/ 1 year warranty for a memphis 4k-4kwatts at 1ohm, they don't sell online, so I'd check the shops. You could get a mm4000.1, that's 4k at 2 ohms.

Again, just depends on what kind of setup you're trying to get, and the coils on the subs.

if they didnt have to be brand new it would be easier as well.

a friend just found two modded memphis 2000d's for 500 bucks...

Yeah, used makes a huge difference, and when you can find an amp at half cost it makes it worth the lack of warranty imo. If an amp cost 2000 new, you buy one used for 1000, and 6 months later it craps out, spend the other 1000 and get a second, or try to repair what you have. My luck it's always right after the warranty goes up when you begin to have problems.

500 for 2 those memphis, is that used? Even so that's a killer deal.

and I heard the Hifonics BXIs are just cheap and mess up pretty easy.

Yeah, I myself have been looking for a decent 4k watt amp (well, 2 of them). I've sort of been beating the subject up trying to find something I'll like before spending so much cash to be dissapointed. I'm looking in the ~1300 dollar range each, but I know I'm looking for a single amp per sub. I'm also willing to take used/refurb as long as they look half decent and work properly.

If you search I started a thread about 2 btl 18s on 4k watts.

There are many 4kwrms + amps out there, but little that meet the budget.

I'd kill for some cactus 5ks, but they're about 2k each.

From every recommendation I've gotten (except those by memphis dealers) the rockford 4k is the best amp for the bill. I can get those refurb offline for 1300, or used for 1100. Warranty is not something I'm sure of with that.

I've owned many used amps, and never had any problems except where one was damaged because of physical abuse, and it was already close to 10 years old.

As far as hifonics, you get what you pay for. I've used 2 of them for months, 1 for almost a year, and they sounded great. With 2 of them on 2 18s I broke 150 tuned for daily, but under some extreme loads I have had them go into protect before I set the filters right.

The one I've had for a year I've cranked for some pretty extended periods w/o it heating up much at all to speak of, and I've put it at 1/2 ohm and cranked it up, forcing it into protect a half dozen times in a row just to see if it would hold up because I wanted an excuse to buy a new amp-and it still works perfectly. I've had a decent experience w/ these amps, and while there is better out there, it's a nice amp for the $.

I'm not familiar with their xx-goliath or more powerful amps- but I've heard mixed things about it.

Memphis seems to be great for the price, not sure if you can get a good price on a soundstream 6500, but I think your best bet is a few smaller amps to get in the price you want.

Realistically, if you can get 4 hifonics 1600ds for less than 300 each shipped w/o a warranty, you should have enough overhead to make sure you don't clip, even if they're over rated by hundreds of watts you'll easily have 4kwatts. If one of them does have a problem 6 months later, you might be able to get a warranty, but if not it'll only be a few hundred instead of $1k+ to replace it.

There are other comparable amps, these are just something I have personal experience with.

Check into the sundown audio 1500s, they're going to be a bit over your budget I think, but maybe denim could tell you a bit more about those.

Have you ordered the subs, and do you know if you want one beefy mama-jama of an amp, or several smaller amps?

theabunai made a good point- I'm looking for 4kwatts, so maybe you'll find something I have overlooked.

I have a guy today who wants me to put a single sub in his expedition. He was looking for a single amp able to put out about 1k watts for when he gets an ssd (he wants me to order his stuff for him). I priced a bxi1206d, and you can get one shipped for about $250- so 1k for 4. That's 200 under the limit, and if you're worried about one crappin' out, you could put an extra $50 in and get a replacement if it goes up.

I just feel that they put out decent power for the cash, and I like the ones I had. Maybe someone else can recommend another amp/company that has decent amps for similar prices.

Hey bud, theres a guy on termpro forum (classifieds) w/ 2 Soundsteam6500s for 1300. No warranty, but they're new. Just thought I'd throw that out there.
