Confused

The previous poster said that the only full range signal goes to the rear doors. You are saying that I need to tap into 4 channels in the front doors, and also the sub? That means I would need 4 channels of amplification for just the front doors? What about the rear doors? Do I need another 2 channel amp for that? (front doors: 2, front tweeters: 2, rear speakers: 2) And I will be using an LC7i

Will someone please CLARIFY once and for all? This is making me crazy!

That's the proper way. 6 channels total. Alpine PDX v5.

As the person above politely stated, if you want something good you need to shell out the dough for it. For me currently, for front components, rear doors, stealth box, amp, converter, wires, sound deadening, fuses etc, I'm about 3G total

Re: Simple Upgrade?

But the Alpine PDX-v5 or the PDX v9 are only 5 channels amps so how does that work for 6 channels?

How is that actually done? I must need a diagram or something... none of this makes sense. That way subbie99 explains it, you would need to go active for the front componets because you are not going to get a full signal from the front doors if you individually dont tap each woofer and tweeter output form the stock amp. Is this correct?

Re: Simple Upgrade?

A simple solution w/o spending hundreds/thousand$ on processors, etc., would be to buy an medium quality LOC and tap into the rear speakers for inputs into it. Run the RCAs to your amp (from LOC), and power a nice set of components in your front doors. These front door speakers will now fade with the rears, but you can compensate with amp gain. The front dash speaker would still fade separately.

Trying to sum all the front signals, etc. would require a pretty decent Processor -- at a pretty decent price.

This will improve your sound, but probably still won't be night&day difference. I plan to try this approach on my Ram (same system) this spring/summer. The only way to get a true audiophile system, would be to replace everything. I will never do that.

Chrysler and Alpine could team up to make a decent system. We know Alpine makes some quality gear. If I were Alpine, I'd be embarrassed to have my name on the current system.

Honestly, the simplest upgrade (title of thread), would be to replace the center 3.5" dash speaker with a good quality one. I've done this on 3 different Alpine systems. It does improve the highs, and makes them more crisp (instead of 'muddy'). Very simple, and will improve little. Once you get into the front doors, it's no longer simple (nor cheap).

This is good news. How hard is it to change the center speaker, and which one would you recommend? Thanks for helping answer my questions.

Just remember, you get what you pay for. If your looking a cheap solution, then the quality will not be what you expect.

Re: Simple Upgrade?

The Center dash speaker is a 10 min job. The long, center trim pops out of the dash. Be careful of the harness for the sensor. Any high-quality 3.5" will improve some. Don't expect a miracle. I actually found a New old stock Alpine set on ebay. Alpine no longer makes a 3.5. Polk, Kicker KS, etc. would be an improvement w/o hurting the bank.

Re: Simple Upgrade?

Hey! I replaced my factory 6x9 with a pair of Lanzar 6x9 sub-woofers and it is an earth to sky difference! That's the only audio upgrade I've done so far and now you can feel the deepest bass notes that were missing the factory set up. Do it! You won't regret it!

Re: Simple Upgrade?

If Lanzar > the supposed-OE Alpine, you know we have a problem.

Re: Simple Upgrade?

Has anyone ACTUALLY changed out their center dash speaker? If so, which one did you use?

Re: Simple Upgrade?

I don't really think Alpine makes those crappy OE speakers, as they looked to me is cheapo Chinese stuff!
