Do amps and subs have to be the same brand?

I have 2 10" JL audio subs in a wedge box and I wanted to buy the JL 250/1 amp, but this amp is $450 and I don't want to spend that much just for a mono amp. Do I necessarily have to have a JL audio amp for these subs? I've been told by a couple shops the 250/1 is made for the box that I have but this amp is too expensive. Can you guys give me some suggestions on what other amps I could use? My price range is $200-250.

No you don't need to use the same brand of amp as you do subs. Contact Don aka Pearl96Max for a great deal on an amp. He will definitely point you in the right direction.

ditto to everything in the last post. I'd go further and say ABSOLUTELY not...you don't need to have the same brand. There's no advantage to it whatsoever unless you REALLY like JL the company, and you wont get too much support on this forum for doing that.....

Yeah Don has good stuff at good prices....plenty more options then good ole JL.

well if that sub is the w7 i would say yes get the JL amp because that thing has a weird impedence. Smart marketing by JL. Other wise not they do'nt have to be the same. You don't neccessarly have to have a mono amp either. You can also bridge a 2 channel.

just because the subs are 3ohms doesn't mean you can't use a different amp! As long as you can find an amp that is 2ohm stable with plenty of power, a 3ohm load will actually be better for the amp and actually draw more controll and dynamic headroom.

for 200$ look on ebay, Kicker's are fine amps... but if your subs are W7's, you're not going to find an amp that powerful for that cheap. Hifonics' new amps aren't bad <--very cheap so don't expect too much.

somewhat true...it's trial and error. I had an alpine amp that could do 2 ohms and 4 ohms.... It would go into protect mode because of the 3 ohms. It's just easiest to get a JL amp if you get a JLW7. Just speaking from my experience...if you search on the web you'll see other people had a similar problem.

if it's 2 ohm stable, i don't see how it won't support 3 ohms...

The subs I have are the 10wo's which produce about 125w each. The sticker on the prowedge says 2ohms.

it's dumb...but some amps can't do the weird 3ohm load.... Some amps can. That's why it's good marketing by JL..

guess what i'm getting at is how can an amp not handle 3 ohms when it can run normally at an even lower impedance.

Just some honest advise here... If your amp is 2ohm stable, and can't play a 3ohm speaker... it's a piece of crap!

Just because a speaker is rated at a certain impedance, doesn't mean it's operating at that impedance... Speakers flux at different frequencies so saying your amp can't handle a 3ohm load means at isn't going to play anything with a 2 ohm impedance either...

Check out <a href="http://www.tcsounds.com/index.htm">TC-Sounds</a> new website, they're the company that makes JL audio and some of their new subs are 3ohms, it has nothing to do w/marketing.

Hey no problem...I used to think that too. I understand that if it's 2 ohm stable, and 4 ohm stable..it should be running COOL at 3 ohms. It should work...but It didin't. maybe it's just alpines...maybe it's other ones too....I dont' know. I only know that the alpine amps dind't work. I have a friend, also with an ALPINE amp that had the same exact problem with a JLW7. Most people don't run into this problem cause they run JL SUB/JL AMP. No problems there.

yeah I totally understand that much... but it just didn't work. Amp played other subs fine...in fact someone on the .org has my old alpine amp. Works great.

I'm here for the gangbang.......


In all seriousness, I witnessed burnurass's problem. Notwithstanding that the Alpine amp *may* have been a POS, it did go into protect mode even when wired correctly.

Was it defective? Alpine amps are more pricey than I would've expected from an entry level company, however, their stuff should be required to WORK none-the-less. I looked at the alpine amps when I was looking for a good amp. I looked past them once I saw how expensive they got near the higher watt range. I stayed on the entry level and got a kenwood amp. I figured $280 was good for an amp that did 500w@4 ohms and 850w@2 ohms.

I would not call Alpine amps or the company entry level.


Is there better to be had, yes, it still does not make them that.

Well I get JL all around, some car specialist say its better to stay with the same brand you can buy and amp that is made for the sub. etc. But I think its better staying same brand for show's

NOpe..not defective. Worked GREAT with another set of subwoofers. Just the JL w7 giving it problems. I'm not saying you have to get a JL amp but if you want it to DEF. work w/o any surprises with the W7 then that's the way to go. First of all there are other better choices as everyone has said.

should have tried the phoenix gold the made an amp that supports all the ohm loads as well and cheaper than the jl but the jl amp 1000/1 sounds amazing sence it has a ridiculous eq on the amp itself.

Is it not just a one band parametric EQ?

sorry missed that
I am not sure on how many bads but I believe any time you state it is a parametric meaning it has more than one band that is what i was lead to believe.

Bassboost is a waste that should be left alone. SS filter only has certain applications where it would apply. LP is all you need if running subs.

What 3 bands does it have?
