I can't remember the model number, but I posted what I could remember about it above. You could do a search for my name as the poster, and audiobahn and you'll find it for sure.

They sound like they were designed for the rear of our car, no joke. I still want a couple of 10's, but I'm happy with where it is right now.

 

So I'm thinking audiobahn AS65V and AS69Q would be good choice, with an overall of about 400 rms, I would need an amp to output that amount, 4 channels, right? So something that says 4x 90-100Watt RMS at 4 Ohms...
As for my subs, I cant any information about the RMS of my subs, is there a way to calculate what I would need? And I'm pretty sure, that if I wire them in parallel, I would need a single channel 1200watt at how many ohms? Like the Nine.1 from elemental designs? Because thats 1200 at 1 ohm, and 400 at 4 ohms... even the 2 channel is 2 x 200 at 4 Ohm...

 

RMS is typically half of what the rated max power is. Your subs say max power is 600 watts max at 2 ohms. This is a little strange. Did you purchase the box pre-assembled with these subs already installed? Most subs will simply give you the RMS power that each coil can handle and the resistance of each coil.

For example: my Type R 12 is a dual 4 ohm voice coil sub with a max of 500 WRMS or 250 WRMS per coil. These two bits of information,resistance and max continuous power, allow me to build the rest of the system.

Your subs dont tell us what the reistance of each coil is and what the RMS rating is of each coil.

My best guess is either each sub is rated at 600 watts max at 2 ohms, OR......that the entire box is already wired parallel and will handle no more then 600 watts max and the resistence of the entire setup is 2 ohm. If its each sub, then yes, if you wire them parallel, they would basically be 1200 watts max (probably 600 WRMS) at a 1 ohm load. The NINe.1 is VERY capable of running a 1 ohm load. If its the latter, then the entire contents of that sub box is rated at 600 watts (300 watts RMS) with an amp capable of holding a 2 ohm load.

Here is another Q: is there only one place to connect your amp to the sub box? Or, is there two connection terminals, one for each sub? Grab a multimeter and find out the resistance yourself. That would be the next best thing to do.

LOL, you know what I would do, is get the NINe.1 It'll either be just the right amount of power, or you'll have so much power you wont know what to do with! Either way, your system should run very efficient. If I were you, I'd keep the enclosure and upgrade those subs. By the looks of them, they probably spent more money on the chrome electroplating of the basket then they did on the R&D of the motor!!! Since this is a multi-chamber and ported enclosure, I amend my recommendations earlier. Definitely look into Rockford Fosgate. Their sealed performance is wanting, but their ported enclosure performance is AMAZING! JL as well, but for the money, RF is the one to check out.

I would suggest the NINe.4 for the audiobahns. The put out 65 watts RMS at 12 volts! They put out closer to 85-90 watts at 14.4 volts when your car is running. Should be a perfect match for those Audiobahns.

 

http://www.trtheaterresearch.com/car/tr-9500.htm is the only info I could find on the subs online, and seeing as the whole thing is on sale for 1500, I doubt I could spend enough to get better speakers atm.
If it's about half, then each sub would be 300rms at 2 ohms, (there are terminals at each side) so if I wire both parallel, then connect it to lets say the nine.2, which gives 200rms at 2 ohms each, it would still be running weaker. I would need to get a stronger amp? Or should I rewire, and hook it up to the nine.1, having it all wired to one side, and it being all parallel, so it runs off the nine.1 at 1 ohm for 1200 watts? Which setup do you think would sound best?

Also, which model of optima yellowtop battery would I get? Is it a big difference? And how hard is it to mount it instead of your old battery?

 

REDZMAN has the bluetop marine optima. PM him and ask him which model he got. Fits great from what I saw.

I would go with the NINe.1. IMO, you should never underpower your speakers. Your amp should always put out more then your speakers can handle. Why you ask? Because most folks will try to use the gain to get the most out of their amps. 1st of all, this is not how you adjust your gain on the amps, the gain should simply be used to help match the voltage that your decks RCA's are putting out. But, by using an amp that puts out more power then you need, you dont have to drive the amp near as hard. Your system will run more efficient, your temps inside the amp will stay low, and you you have less of a chance of sending powerful DISTORTED signals to the subs. THIS is what causes subs and speakers to fail.

Yes, you have to be responsible with the extra power, but, if you are, I guarantee that you will have less blown apart subs and speakers by using a more powerful amp responsibly, rather then using an underpowered amp irresponsibly by trying to crank the gain too high.

 

I can't remember the model I have of the blue top, but it's the 6 cell one with dual posts. The stuff is mostly worn off the label I think, but I'll look.

If you search here, it may be listed.

Nevermind, went and did a search real quick, D34M.

Got it for $135 shipped on Ebay about 8 years ago. Still rocks.

 

So with the nine 1, 4 audiobahns, a capacitor, a bluetop, proper wiring, I should have a great setup for a sound system? And should I look into if my alternator can handle it?

 

My alternator handles it just fine, and its stock specs.
