good amp for these speakers

[navarachi]

Hey guys,

Im looking for a good amp to power my alpine type r components and a good amp to power my alpine type e 12's. I would rather over power than underpower. Your suggestions are greatly appreciated. I just haven't had that many amps and would like to make a good investment.

Thanks

A few good matches would be:

JL / (Slash) series 450/4 (or 300/4 if you don't need that much power) and 500/1

Alpine MRV-F545 and MRD-M605

Audison LRx 4.300 and 1.400

All of the above would be very good matches for your setup. The JL will give the most output, the Audison will be the cleanest, and the Alpine will fall somewhere in-between at a pretty good balance.

Good luck,

-James

what do you think about this ? For 2 JL audio 10"

The absolute cleanest sound will come from Diamond Audio. It would work best if you have a deck that does not have an amp. An in deck amp will only degrade the signal. Here are the best signal to noise ratio amps available:

Im not trying to step on James's feet because he is the resident audio guru, but the best systems/amps/speakers/etc I have heard are Focal, followed by Diamond, followed by McIntosh. Jon.

I'd avoid the Boss Audio stuff... It's pretty commonly used in SPL comps and burping contests, but it ain't good for audio quality and every day usage...

Diamonds are great amplifiers, but as far as being the best goes I'd put Audison (and a few other series) up against them any day for flat out SQ performance... They will both do far beyond what most people would ever recognize or need (especially running low to mid end speakers, even many high end). Focal is actually about to launch their amp line-up in the US as well... that should be a very promising array.

There's really no reason to power subs with an amp that has a minimal S/N ratio or THD... it's more important to power them properly with efficient levels that are inaudible at the majority of the spectrum... Your mids and highs are where the THD and S/N ratio really come into play, and you will need to consider that when choosing the amp for those speakers. The Type Rs are a tight set of speakers, and I would definitely match them with a quality amp. Fortunately they are pretty versatile speakers, and aren't too finicky about the power they receive. If you're going for cost effective (which I assume you are since you inquired about Boss Audio), I'd go for the Alpine's I mentioned above... Of the three setups I listed, they are the least expensive and second most musical. Line for line, they don't quite match up with the JL or Audison for output... but that's why I listed the slightly higher rated amps (which should still run a bit less money). Their S/N ratio is not quite as good as either of the others I mentioned, however they are still very solid amps, and are more than sufficient for running the Type Rs and JL 10"s... Also, Alpine uses slightly different methodology in their rating schemes for S/N which portray lower #s, so don't be turned away by them.

I'd agree with much of what you are saying (with a few other lines added in, and slight ranking differences)...

What I disagree with, however, is matching a $1000 amp to a $150 set of speakers (or a $150 amp to a $1000 set of speakers for that matter)... In my experience, you will run into a concept referred to as "diminishing marginal returns" (yea, a big economic term) when powering unmatched sets... In this case, the speakers will become the bottle neck in the setup and you experience very little, if any difference in performance over running a slightly lesser amp that better matches the set of speakers. Likewise, you can keep a middle end amp and upgrade from a matched set of speakers to a top end set of speakers and experience very little gain in quality... As a matter of fact, if the amp isn't sufficient, you can LOSE quality...

He already has his mids and highs (Alpine Type Rs) and his subs (JL 10"s, I'm guessing W3s for middle ground)... Sure, you can push them with a Diamond or a McIntosh, however would the increase in SQ / Performance really justify the cost difference over an upper-middle end set of matched amps? I question the validity from a pro standpoint, let alone from a casual listner's...

The key is to be happy with the way your system sounds... Everyone has their own tastes, and there are setups that can appeal to anyone. My personal recommendation is to get the most of what you got, with the least amount of sacrifice (budget, space, weight, whatever other limits you may have). Considering the speakers he's running, and the fact that he just inquired about a $150 Boss amp, I ain't gonna try to shove a $800+ (each) Diamond or McIntosh down his throat... It's a balancing act, and there's really no need to over-do one end of the spectrum while leaving the other end behind.

Peace,

^^^I totally agree...

You want the cleaner amps to power the Tweeters and mids (your point sources coaxial or components). The amp that powers the Subs should only be clean enough to prevent distortion or clipping. It also depends on the application. For instance the type of enclosure your going to mount them in… A sealed box will require more power to get the same output as the ported or bandpass box. I prefer the sealed because it is more versatile to all types of music (tight bass/ long bass extensions). My choice would be a MONO D-class amp with at least a THD rating of .1... Now if your going to run some MTX Jack Hammer, I'd go with Hyfonics Goliath & Maxximus (money being no object and just SPLs and not sound quality):lol:

LMAO!!!

As you know, bro, I've always tended to lean toward Soundstream, especially for their Old Skool stuff... but their current line-up has taken home many SPL Competitions (and actually share a lot in common with the Hi-Fonics, considering they're both Power Acoustic products now)

Pair two of these bad boys up for an effective 20,000W RMS...





Then pop four of these 'little' beasts in the space you'd fit one Jackhammer (for about the same price, and you save around 60-80lbs in the process)...






And they'll slam all over the MTX any day (trust me, I've seen these things in action)

My brother in law said i need atleast 1,000 watt and it also needs to be one ohm stable. ??? I dont know what any of this means hehehe but is this right ? just 2 power my 2 10" JL audios ? And a 4 channel amp for my panel speakers. Keep in mind i have the stock JBL speakers.

Do you know what series the JL subs are? That would make all the difference in the world... You can EASILY power any 10" JL below the W7 series with less than 500W / Channel... That's a BIG load! The W6v.2s can take it, but they don't need it.

Get some more info on the subs and it'll be easier to help ya out.

[rec]

they are W4-4

[theprodigy79]

The W4-4 are Single Voice Coil (SVC), 4 Ohm subs... I have no idea why your bro in-law's telling you that you need a 1 Ohm stable amp to power them... Also, their continuous power handling is 200W a piece, so I'd use an amp that's capable of between 400-500W x 1 Channel RMS, 2 Ohm stable... You WILL fry those subs by pushing 500W to each... Maybe he was thinking you had W6s, which then would have been pretty accurate...

So, basically... for best results you need a 500W RMS (either 250x2 or 500x1) subwoofer amp and a reasonable 4 channel amp... If you're still running your stock JBLs (and you plan to keep them) I wouldn't go much over 45Wx4... That would power most after market speakers very efficiently as well if you planned to upgrade.

Lemme know if you have any other questions bro.

thanks that makes alot of sense to me now lol

[navarachi]

thanks for the replys, i would like to buy two great amps but money is an object at this point, but quality is too. I'm looking into the alpines, any other suggestions, i need a class A for the components and a class d for my type e subs.

Thanks so much
