Since you used a LOC, the fade will play a key role in the signal to the amps. It's just like when you adjust the fade all the way forward, the front speakers get louder because you are increasing the signal to them while decreasing the signal to the rears. If you adjust the Fade more to the...

Class A/B amps are also multi-channel amps. These are generally used on non-subwoofer speakers (your regular internal speakers and tweeters) due to their low THD ratings. A THD rating is basically the distortion ratio, a low THD rating will produce a cleaner amplified signal. This is very...

No, you can still hook up multiple subs when an amp is rated x 1 channel. You just have more then one + and - wires connected to the same terminal. Either amp would work for your setup. Either way you would want to wire in Parallel (+ to + and - to -) to achieve the 1ohm total load required...

You're referring to Drag Pipes. They have no baffles (internal mufflers) and are illegal in just about every state except for racing applications (which is why you can still get them). If a cop can put his nightstick up the tailpipe (now there's a visual!) and not hit a baffle, then it's...

I know what you mean about hearing it inside houses. I just installed my latest system in my '97, and it will damn near blow your ear drums out from inside the cab, but outside it sounds like (2) 10's or something low powered. But I've had people sware that they could still "feel" the bass...

I just installed an Alpine CDA-7995 MP3 headunit in my '97. The adapter that came with it was very easy to install (it's the one with the pocket on top like RattleSnake96 mentioned). All you have to do is remove the factory headunit, then snap the new adapter in place. My adapter had 2 tabs...

Don't know about (2) 15's, but I'm running (2) 12" RF Punch HX2's that will rival most dual 15" setups. Should be hitting between 150 and 160 db's, but I haven't had it measured yet.

Mbrooks420, on that note I'll agree. I was referring more towards highway riding, not residential areas. I've been to a few ABATE meetings in my area (mostly older grumps), and have seen the same thing. The cops put a stop to the noise problem though by waiting outside the meeting area...

IZACKARY noted the best/easiest method going. "Popping" a speaker is a very common method of determining polarity. You can use a 9v battery as well, anything to send current to the speaker (I've even seen installers use a cordless drill's battery pack before). And don't worry, as long as you...

Honestly, I build systems to keep the sound in and vibrations out. Nothing's worse then having a punk kid pull up next to you and the only thing you can hear is their car vibrating and ratteling because they know nothing about sound/vibration dampening. That's what I find annoying. If someone...

Not too bad. Hopefully you ordered the 4ohm DVC model Comp VR's. You can wire each sub in parallel to it's own channel @ 2ohms and get 400 x 2 @ 2ohms. With the 4ohm DVC's you could also wire both subs in series/parallel and bridge the amp to get 600 x 1 @ 4ohms mono/bridged (breaks down to...

You also have to account for any internal bracing or port displacement as well. What subs are you running (because just about every manufacturer's "recommended internal volume" is different)

I haven't had any personal experience with Audiobahn amps, but their rep is excellent. I post on another forum for audio applications/questions, and the experts there all say that Audiobahn amps are well worth the money (IMO their subs lack the same quality, but that's just MO)

Clipping is usually caused by an impropper ohm load (applying an ohm load below what an amp is stable at). If you have a sponser then clipping can bring home trophies (since it wont be your money replacing the amp). But if you have to spend the money out of your own pocket to replace an amp...

I verified it's the 130a. And no, I ran new wires for the amps (I hate factory wires, I replaced everything for the stereo with upgraded wiring). And let me tell you what, running wires through the cannon plug on the drivers side door is a major pain in the a$$!. Eventually I'll mount the...

Actually it's quite common to over-drive a sub. You run a risk though. Quality subs should not have a problem running at RMS + (1/2 the difference of Peak-RMS). Meaning, if the subs RMS value is 700 and the Peak is 1400, then you could theoriticly run up to 1050 watts per sub. They wont last...

The JBL BP1200.1 is an excellent amp, and often overlooked. It's 1ohm stable and would drive those subs nicely (even though I'm not a fan of Audiobahn subs). Audiobahn amps I like, but not the subs. With the AW1200's being 700RMS, you could get around 600 watts a piece with a JBL BP1200.1...

Good morning everyone. I have a '97 4.0 SOHC 2-door Sport, and I've got a couple of questions for 'yall... 1) Is my stock alternator 130 amps? I've read some articles that say yes, and some that say no. 2) I'm getting ready to install a 120 amp isolator, and put a second battery (red...

If you bypass the factory amp then the sub is useless (unless you reconnect it to an aftermarket amp). I've never seen an OEM headunit with RCA pre-outs before. I'm not 100% familiar with the JBL premium system (as in how many OEM amps there are), but Ford seems to daisy chain all their amps...

You will probably need an OEM Amp adapter if you plan on interfacing an aftermarket amp with a factory amplifier. Scosche makes one. It allows you to change the output voltage of the aftermarket headunit to match what the OEM amplifier(s) need, you'll get a really muffled sound from the...

Actually, you can get a Line Out Converter (LOC) from just about anywhere. It converts a pre-amplified High Level signal back into a non-amplified Low Level RCA signal. I've never trusted the High Level inputs on any amp. By using a LOC, you allow the aftermarket amp to do just it's job...
