Subject: Amp Size
Date Posted: May 31, 2004 at 11:48 AM

I am getting 2 Mis Bass 5 1/4" Speakers 200w RMS, 2 ABF 6x9" 3 Way Speakers 250w RMS & 2 25mm Titanium Dome Tweeters 100w RMS for my setup.  What size amp would you recommend to run this and what OHM should I run at?

First of all, I assume all the speakers you are buying are 4-ohms?  Then your amp will "run at" 4-ohms.  Ohm loading depends on the speakers, not the amp.

Second, are you planning to set up the mid-bass and tweeters as a component set in the front of the car?  Do you have a proper 2-way passive crossover for them?  Do they match (are they from the same manufacturer or at least do they  have similar timbre?)

Assuming the RMS ratings on the speakers is accurate and you are not actually quoting peak ratings, get a good 4-channel amp that is rated at 150 to 200 watts RMS per channel.  Run the 6X9s off 2 channels and the mid-bass/tweet sets with proper crossovers off the other two.

I am going to run crossovers with all the speakers.  Everything I am getting is Audiobahn and the numbers I quoted are RMS and not peak, as described from them anyways.  You asked if I plan on runnging the front as a component set, what exactly do you mean by this?  I will be hooking everything up to the amps.  If I post the model numbers, would that help you?

The tweets and rears are 4 ohm but the mids are 3 ohm.

Crossovers with all the speakers?  What do you mean.

The midbass and tweets should be used together with a passive crossover between them.  Like this, at the very least:

OR you could get a good crossover like the Audio Control 6XS and a 6-channel amp (or a four channel for the mids and 6X9s and a second stereo amp for the tweets) and use all electronic crossovers before the amps.  It depends on how you'd like to set it up.

And don't take this the wrong way please, but if all of this is new to you, then I suggest you get some help from a professional install shop in your area.  The best way to learn is by being taught.

Ok, then here is a suggestion.  Don't buy seperate mid-bass and tweeters.  Get a component set designed to work together.  If you MUST stay with Audiobahn, look at their sets like the ABC525T or 5002Q.  This will make your choces easier.  There are far, far better brand choices than Audiobahn, by the way...

The main reason I was thinking of staying with Audiobahn is because the subs I currently have, they really take a pounding and I have had no problems with them.  Here is a list I came up with but if you can suggest something better, let me know.

Deck A3451D - $567.36

Screen AVM170TP

2 A1500HCT 2000W Mono Hi-Current Flame Amps

2 15" Subwoofers - 15" Flame Subwoofer 2000RMS AW1508T

2 Mis Bass 5 1/4" Speakers AMD50Q 200w RMS

2 ABF 6x9" 3 Way Speakers ABF39T 250w RMS

2 25mm Titanium Dome Tweeters AT69 100w RMS

Also, can a HU DVD play backup DVD's, if not, I will just get the MP3 HU and a PS2.

Again, I suggest you do not buy seperate mid-bass and tweeter components if you don't have experience setting these up.  Get a component SET already matched with a crossover.  Are you talking about burned DVD's? It depends on what system was used to encode them.  Not all DVD-R's are compatible with all DVD players.

You mentioned there are better products then Audiobahn though.  Do you mean for component sets or would you recommend I get HU, screen and speakers elsewhere?  Yes, burned DVD's is what I am referring to and what would I look for that would tell me a HU would play a burned DVD?

I am not trying to trash Audiobahn.  I for one simply do not like them.  And yes, there are many better quality manufacturers out there for every piece in your system, including Alpine, Eclipse, Nakamichi and many others.  But if you like them and want to buy Audiobahn, then by all means go for it.

I am suggesting, if you read my earlier posts, that you do not purchase unmatched component speakers unless you are advanced enough to understand how to build your own crossovers and/or you understand how to set up a bi-amped system.  Your questions indicate this is something you do not yet understand.

Buy matched component sets with crossovers included.  Audiobahn makes these, and I posted a couple of model number suggestions for you earlier.

There are several DVD formats, such as DVD-R, DVD+R, DVD-RW and others.  You need to make sure whatever player you get is compatible with whatever burner you use.
