What do you think of my system so far?

[new_united]

I recently bought 2 infinity perfect 12s and the Pioneer head set... i want to get the nicest sound quality so that's why i bought the perfect 12s.. I am now stuck on which amp to buy to power them.. the RMS is 350 on the perfect.. and keeping in mind that i do want really good sound quality i also want it fairly loud... can you recommend the best amp or amps i should use to produce this result.. i've herd good things about alpine...

thanks alot

i forgot to mention that my pioneer head set was a DEH-P8400MP

Go look at Memphis Car Audio. Thats what I run in my car and it works for SQ and SPL.

Cleanest sound you will find will be PPI Tube Amps...good bloody luck finding them. If you're really into clarity, you can settle for a good McIntosh or Phoenix Gold amp. Stay away from anything that sells for less that $1 per watt. Alpine makes some fine headunits but the amps are exactly what they say they are. McIntosh likes to underrate their amps If by some amazing miracle you can find a MC4000M for sale, grab it. They retailed for about $4,000 in 1997, look for $1,300 now. I ran an 18w3 and a set of Focals in my 300zx and it had no problem making itself known. It weighs about 75Lbs and you will have to work to make it fit. I floated the amp above my sub on plexi legs, the sub lived in the spare tire well. Anyway...that's where the money is.

well, no matter what kind of amp you buy, w/o a front set of components, and improper tuning, you will sound like , no offense , ghetto..... Tube drivers, mono amps, .......buy a good front stage, use one amp on them, and parallel the subs, on one other amp.

gl.....sorry ? is kind of vauge

you're not gonna hear a difference in sound quality on an amp pushing subs....my advice is to pick up any decent mono class d amp for your subs....

 

[new_united]

why a mono class anf not a multi channel one?? and what's a class d?

Sorry i don't know that much

 

[GovernorKC]

a mono amp is a single channel amp and a class D amp is a digital amp. they don't take as much power to produce power. if that makes sence.

 

[pensfan76]

I had a PPI that produced nice clean power,
till i fried it

 

[new_united]

GovernorKC i love the way your system looks man.. that's chill.. what exactly did you do and if you don't mind how much did it cost, not including the actual audio equipment... thanks man.. if i have two subs shouldn't i not have a mono amp? i'm still not sure what a channel is and what is the point of them if they take more power??

 

[new_united]

and this sounds really stupid but what's the difference between the # of ohms.. it gives different watts for different ohms

 

[GovernorKC]

hey thanks a lot New United, I basically took out the carpet in the trunk, then layed it on some 3'4" MDF and traced it. then cut it out for the base, i put 2x4s underneath to give it enought height for my amp to lay flush. i routered the 2x4s to allow a grove for the plexiglass to slide in. it was pretty simple. i just did it different things as i went, i didnt have any plans. the back side of the box is made of plexiglass with 2 neons in it. so with the rear seats down you can see the back of the subs. any other questions let me know. peace

Think of the Ohms like this. You have Power, but you have to move it in blocks. With a 1 Ohm set, you move power that's one block wide. If it's 8 Ohms you have to move it 8 blocks wide. If you're amp is only stable at 4 Ohms it can run 4 or more blocks wide. If you try and run a speaker or two that ask for double blocks, (2 Ohms) you get too many flowing out at a time and poof, fried amp. On the same token, if the speaker or speakers are asking for 8 Ohms and your system is capable of 4 Ohms, the blocks have to be broken down and you only get half the power. 200W at 4 Ohms = 400W at 2 Ohms = 100W at 8 Ohms - Now that doubling is not an absolute rule...but it's close.

well, you're dealing with subs.....with a mono class d, you're gonna get the most number of wiring possibilities ...which will allow you to get the most power out of the amp without frying it. plus, with a class d, you'll be able to run a high wattage amp with minimal draw on your car's electrical system. it's the way to go.

Maybe I'm old fashion but I still prefer the old syle Rockford Fostgate Punch amps to power subs (if you can get ahold of one). They just put out raw power and sound great. I have an old punch 250 and am going to use that to power my JL's. When I had this setup in my old car it was very clear and sounded great.

As far an amp to power the mids and highs I have always liked Xtant with Boston Aucoustic PRO Components, but that setup would be really expensive.

There are a couple of guys in my car club that are running Memphis Audio amps and componets and they have really impressed me. I think they sound as good as the Xtant and Boston setup so I might have to go with that when I upgrade. There is one guy in my club that is sponsored by Memphis and I have to say over all what I have seen of Memphis as a company has really impressed me. His car sound phenominal, it has the clarity of a system that would cost twice as much.

i have infinity kappa series 10's and i use a directed 600d amp it makes them 15's they sound great for some reason i keep having to buy new pairs every few months cause it just kills the subs but i know the perfects are better so theyu won't blow the directer amp is a mono class d amp a very good amp!

I must not be reading that right...makes them 15's? Please clarify your jumbled statement. It sounds to me that you bought a crappy amp that's pouring distortion onto the subs. The Infinity's are built to deliver crisp, tight sound, not deep rolling bass. They handle loads of clean power, obscene amounts in the thousands, but if you put a little distortion the into the mix, you lose your voicecoils. Even a little 200 watt amp will lock those speakers up with more than 2-5% THD. (Total Harmonic Distortion)

he said he's got a directed 600d amp...dei makes a very nice amp. so i don't think his subs are blowing because of that. prolly needs to set the crossover differently, turn down the gains, wire the subs differently, and/or not turn that volume knob all the way up. the sub's enclosure could also play a role in the actual sub not lasting (ie. a very large, ported box....which would cause the sub to over-extend)
