How much RMS power for my BA setup?

[Matthew]

Ok i dont care about fade and balance cause i never use those features, so could hook up my BA RC620s and BA NX67s to one 2 channel amp right?

What size amp would you recommend RMS power? like 140x2RMS etc.

I have done this in a few cars over the years, and honestly we only did that as a temp fix. Being able to set the soundstage to where you are at is pretty important, but it's something that I usually adjust at the get go and leave alone. If you are using the BA's spend the cash on a good four channel. But 140w amp should drive both sets pretty well for awhile. Another thought, I forgot did you pick up that sub amp? If not pick up a four channel and use two for your speakers and the other two for your sub.

 

[Matthew]

i dont have subs.

Bad idea in general...yes you don't like fade or what have you, but the easiest thing to do is this:

1 cheaper 2 channel amp with 45W-75W rms to the components (I recommend an Eclipse EA2212 or the Alpine MRP-T220, but lean more towards the Eclipse) and then run the rears off the deck power. It's actually easier and cheaper than doing what you just described. I also think it'd sound better.

 

[Matthew]

you really hate the rear speakers, huh? i guess i could get that amp...

A good rule of thumb... regular wattage is ABOUT double the RMS wattage... so if you have 140x2 = 280 RMS, and you wanna use the full speaker potential, get something around 600 Watts, but dont overpower it. It can blow it at full volume.

 

[servoeyes]

Well...it's not that I hate them, but with 50W vs 22W you'll still be able to hear them a bit. This way they won't be overpowering, and that's the real key.

See...everytime I get into other peoples' cars and they have rear deck mounted speakers, I cringe. I know my listening experience (especially if I'm in back) has just been ruined. Now I can't talk to them because I can't hear what they're saying, and all the music sounds like it's coming from behind me. And if I'm in the front and the fade isn't set like in my mom's car, then everything still comes from behind me and it's just annoying! This way people can hear you talking to them, and still hear the music.

 

[Matthew]

so should i take aikens advice and get a stronger amp?

 

[servoeyes]

I don't think you'll need a stronger amp with those components. The Eclipse would be perfect, I think or you'll over power the rears. Believe me, 50W is plenty good for those. Once you get a sub your system will be really balanced. If you do want more power step up to the PA4212 130x2 or the EA3422, which I have, (running bridged) for 120Wx2. I can't even get to 120W...it's wicked loud with my speakers!

 

[Matthew]

id like to keep it as much the same company as possible, is that stupid to do?

 

[RyanJayG]

take servoeyes' advice... I keep adjusting the fade till the rear speakers sound dissapers into the ambiance. if you do this then the rear passengers wont be dissapointed, they'll still hear the music, but it will sound TONS better in the front.

 

[servoeyes]

Unless you're going for a show car it's really unnecessary. Alpine does make amps which would be a good match, but their SN ratio isn't near Eclipse's. Here's how to make your decidion a little easier:

If you want maximum clarity of sound, a very transparent sound that stays very clean and bright get the Eclipse.
If you want a warmer sound that has good SQ and is clean and powerful get the Alpine (the MRV-T320).

The alpine will probably cost more, though...

 

[Matthew]

bah i was hoping to get the Eclipse EA2212 on ebay but no luck.

 

[Matthew]

bump

ok i bought the amp you suggested (alpine one, couldnt find the other on ebay and im impatient)

will this be all the stuff i need to install it - http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3075495648&category=14932

 

[servoeyes]

which alpine one...the MRV? You'll need the wiring kit with a fuse holder and fuse. Make sure you get something of decent quality...I suggest KnuKonceptz. Always been one of my favorites! Apart from that, just a wire cutter, knife, and some vise grips.

 

[Matthew]

got a link to the kit you suggest on ebay?

 

[servoeyes]

I haven't bought from ebay before so I don't know their quality. This is what I would buy in your case. Then, when you get a sub amp you'll be all set except for a distro block. and a little extra wire.

 

[Matthew]

thanks i dunno what id do without you

 

[RyanJayG]

damn, that is a nice kit for cheap... they use all oxygen free copper wireing.... nice

 

[Matthew]

how hard is it to hook up the amp and everything? ive only installed stereos on coupes, never sedans, so how hard is it to run through and extra set of doors? where does the power wire go into the battery (im assuming through the firewall, but if i remember we had a hard enough time getting a small ass wire through that hole)? how do you snatch the wires from the front doors to bring them back to the trunk for the amp? and one last question: how hard or expensive do you think it would be to cut a section of the rear plastic part of the trunk and mount an amp inside there with plexiglass covering it?
