Need Some Advice about my future system

I need to know all you guys's input on my system that I am saving up for.My budget is only 1,000 buck so keep that in mind. So far this is what I am going to get. Oh, I almost forgot all of this stuff is going in my 1999 Ford F-150 XLT. I am getting (4) Pioneer TS-A6857 6x8's ($43.00) to put in the factory locations in the truck; they run att 200W each so I'm getting a Visonik 1,000W 4-channel Amp V4208 ($183.00) to give juice to those Pioneer's. While a Profile California Series 1,200 Watt ($165.00) gives juice to (2) Audiobahn ABP 10 Dual Sub Box w/10" Sub+Neon that run at 600W RMS (per box)($145.00 each). Also, for the head unit, I'm getting a Panasonic CD/MP3/WMA CQDF783U($187.00). I know that some of this stuff is crappy, but it's all that I can afford. Well, I mean when I get the money anyways. But feel free to offer your comments and suggestions. I would really appreciate any help. Thanks alot.

The Pioneers aren't bad. I'm running TS-A6867's (the 3-way version) in my Mustang. My next set of coaxial's will be 2-way's though. Just some food for thought, the TS-A6857's don't "run at 200 watts". They're 50RMS 200Peak. The Visonik amp you mentioned is 250 x 4 @ 4ohms. Unless you turn the gains down you'll end up shredding them.

I've never been a big fan of Audiobahn subs, but to each his own! If I read your post correctly, you're getting 2 Dual 10" sub boxes, totaling Four 10" subs? If that's the case then the Profile amp wont be strong enough. If the Profile amp you mentioned is the CA1200, then you get apx. 450 x 2 @ 4ohms, 900 x 2 @ 2ohms, or 900 x 1 @ 4ohms bridged. The 1200 watt rating is Max power, you'll never see it. Depending on which model bandpass you're getting will determine the total ohm load. Audiobahn lists their 10" bandpass enclosures at either "4ohms Mono" or "4ohms Stereo". I'd need the model number of the enclosure you're getting to determine a better amp.

Hey man, thanks....but what is a good amp for low budget for my subs. I mean I can find a little one for my Pioneer's since I know what the specs are.

Hey squirrel what about the Kicker KX300.4 KX-Series Multi-Channel Amplifier for my Pioneer's would that be okay?I still can find a budget (but good) amp for my subs. If anyone can help, feel free too.

The Kicker is a little on the low side. You want to find an amp that's around 50-100RMS x 4 @ 4ohms.

The Kicker KX300.4 might have mislead you because of the 75 x 4 rating. But that was the 2ohm stereo rating, your speakers are 4ohm's. The 4ohm rating for that amp is 38 watts per channel. Kicker also rates their equipment's RMS output based on a 13.8volt system. So now you're looking at around 30-35 watts per speaker. It's not too bad though if you really like it. I'm running a Kenwood KAC-649S and only pushing around 30 watts to my Pioneers, but I had another one laying around so I'm going to install it and bridge the front speakers to one, and the rears to the other for about 80 watts per speaker instead.

Keep in mind that unless they specifically say rated at 12volts, then they probably used 14.4 or 13.8 volts to rate their amps. You have to factor that in if you're running a 12 volt system (you end up wasting money otherwise!)

As for a sub amp, I think the
JBL BP1200.1 would do you nicely. It's a Class D mono amp designed for subs, and it is 1ohm stable. The power output is the same at 1 and 2ohms with this amp (which is why it's listed in the manual but not in the quick specs on the site). Its 1200 x 1 @ 1 and 2 ohms based on a 14.4volt system. On a 12volt system you should get at least 1000 x 1 @ 1 and 2 ohms, which should do you nicely. The JBL BP series is a good line, reliable and fairly inexpensive.

Hey thanks for the help, but I need a amp for my subs that is 2 channel because each box has one plug to it, but each box has 2 subs so I'm need something that will push 600RMS x   2 at 4 ohms. Because each sub box says 600RMS. sO fi you can think of any subs out there with these specs or better tell me about them but if not somebody please help me think of a better budget subwoofer plan.

You do not need a 2-channel amp! It's a common misconception that since a mono amp only has 1 channel that it can only run 1 sub. That's not true. You can wire as many sub as you want into a single channel as long as the total ohm load does not go below the stability of the amp. And in the case of the JBL BP1200.1, even though it is a single channel amp, it actually has 2 seperate sets of + and - for ease of wiring multiple subs. Both channels are identical, and wiring 2 subs to the BP1200.2 with 1 sub (or box) wired to one set of + and - and the other sub (or box) wired to the other set is actually the same as wiring both subs (or boxes) to only 1 set of + and - on any other mono amp.

Most of the pictures of Series and Parallel wiring of subs makes it look like you only have 1 wire per + and - and the subs are actually wired "together". But this isn't always true. Instead of using 1 wire from the + going to sub1+ and sub2+, can actually be done with 2 wires... where each sub+ has its own wire going to the same + on the amp. It's perfectly safe and is done all the time.

In your case, Audiobahn has tried to make it easier to figure out. And instead of worring about the wiring to the individual subs, they have only told you the ohm rating of the "entire box". Meaning that at the terminal connection for the box, there is already a 4ohm load. It's a little wierd to comprehend, but that's Audiobahn for you!

The reason I asked if your enclosures were the 4ohm mono or 4ohm stereo version is because the 4ohm mono version only has 1 set of external speaker connections (only 1 + and -). The stereo version has 2 sets (2 different sets of + and -).

If you have 2 of the 4ohm Mono enclosures, then with the BP1200.1 it would actually look like you were wiring each enclosure to it's own channel, since they provide 2 identical channels. see Figure 1. This will produce a 2ohm total load at the amp.

If you have 2 of the 4ohm Stereo enclosures, then with the BP1200.1 you would wire them like Figure 2. This will produce a 1ohm total load at the amp.

Either way, the BP1200.1 is stable at both ohm levels, and produces the same amount of power.



If each of your enclosures only has 1 set of terminals, then you have the 4ohm Mono version and would want to wire it to the BP1200.1 like in Figure 1

If you used a normal Class D mono amp that only had 1 physical channel, then you would wire you enclosures to it like this...



Remember, just because it is a 1-channel Mono amp DOES NOT mean that you can't wire multiple subs to it! It's the total ohm load that you have to worry about.

Hey, I would like to thank you for the info, but is there any good amps that you know of that would work good with those Audiobahn boxes that is just a little cheaper. I can't afford to pay 500bucks just for the amp when my budget is only 1000 for the complete system.

Hey, maybe you can help me out with another problem. How do I hook up two amps. I mean I am not going to use two amps to run one speaker, but you know my setup. One amp for door and rear speakers and one for subs. How do I hook to of them up?

Your headunit has 3 sets of RCA Pre-outs (Front, Rear, and Sub). Using RCA cables, connect the Front and Rear Pre-outs to the Front and Rear inputs on the amp for your front and rear speakers. Use RCA cables to connect the Sub Pre-out to the input on the sub amp.

Does every head unit have three pre-outs or just certain ones? If certain ones, then does the Panasonic CD/MP3/WMA CQDF783U have them?

Only certain ones. I looked up your headunit before my last post and from what I found it has 3. If you look on the back of it you should see a total of 6 round plugs, usually 3 white and 3 red. They should be marked Front, Rear, and Sub.

Okay, thanks man I really appreciate your help.

The JBL BP1200.1 can be found for well under $300 if you shop around. I've been running two of them for more than a year now and have not had any problems.

Cool, thanks everybody for the help.
