Re: Some audio update questions..

Great choice on the HATs. I would use their cross-over, but they will be useless until you add your amp. If you run them off the OE amp, you will not obtain any decent sound. Don't worry about the 4 ohm vs. 2. Running 4 ohms instead of 2 will have less strain on the amp. You don't have to spend $600 on a DSP (although that would be best). You can get an Audiocontrol LC6i or LC8i. I have the 6i in my Ram -- and have some success. It's not a DSP, but it will sum your channels in order to produce a full-range signal to your aftermarket amp (which is what you need). It will also provide remote turn-on for your amp, and it itself does not need one (signal sensing turn on). I have 0 noise with the LC6i. Beyond summing, it won't level/EQ. For that being said, I'm very happy for the $102 spent. Trust me, I tried everything to avoid it. You won't be happy running your HATs off the OE amp, or off your amp -- unless you can SUM at least 6 channels first. I'd almost recommend summing 8 -- after playing with mine for weeks.

Re: Some audio update questions..

A 4ohms "motor" is bigger than a 2 ohms "motor" thus in theory the amp will have to work harder to move the new speakers, to a point where it may just overheat.

Like I stated above, it's useless to run them off the OE amp anyway. Try it. It will be marginally better than stock, but nowhere near the $400-500 paid for the speakers. Running 4 ohm speakers off the OE amp would be the least of my worries. I've played with my Ram system for months. I'm finally at a "somewhat happy" state. I

Re: Some audio update questions..

Ahhh thank you kkreit! $102 is alot better than $600+ Ok.. i was just looking at the lc6i. So i would want to sum my front tweeter/mid and send those to the 500/5

arn't the rear doors coax's? i havn't looked.. or does it count as the rear doors+those rear pillar tweeters for the rear channel?

And then the sub output? wouldn't a LC8i be needed? lc6i wouldn't have enough inputs for all that would it?

Re: Some audio update questions..

For my LC6i, I summed the front doors, dash speakers(door tweets in Jeep), and subwoofer. I tried the rear doors instead of front tweets. This produced too much treble. An LC8i may be better. The rear door speakers are not full-range either. Put your ears down there. In the Ram Alpine systems, the rear door speakers have treble boosted, and no lows (very stupid for a 6x9 speaker). The front door speakers (6x9) play mid-range only. I tried both (individually) before I bought the summing device. One produced ear-bleeding highs, and one produced no highs. The system really sucks to upgrade. I may just break down any buy the JBL MS-8. That wouldn't be much more than buying another amp, and a good EQ. You can pick them up on Amazon for $400-something, or slightly used for $300-something. In general, you'll want to summ your Front MIds, Front Tweets, and OE subwoofer. This should produce a near-full-range signal. To play it safe, you could get the LC8i, or Kicker Summ8 to also throw the rear door speakers in the mix (in case we may be missing some upper-range).

Correctamundo my friend, but technically it is the amp won't deliver its rated power if the speaker impedance is high. Reduction of maximum volume before distortion is what you'll probably notice as a result, however don't forget the speaker's efficiency in the overall "volume" equation. I didn't get any bites on this comment so I'll reiterate it is very important when trying to maximise output from a fixed power system. Often OEM speakers are chosen / specified to be very efficient, and high end replacement gear is typically far less efficient.

Watch those dB/W specs!

Cheers,
Steve

Re: Some audio update questions..

^ I feel your pain. It's very frustrating. I can tell you I already made a huge difference in my Ram, and I haven't spent a lot of money. I have spent countless hours (many experiments, tuning, etc.). I'm still not completely satisfied coming from my previous THXII Lincoln system, but I'd probably have to spend $thousands more to get at that level. Currently, my front stage sounds decent. The back still sounds horrible (stock speakers). It's only the kids back there, so they don't care.

I was also going to do my Jeep, but after this, I think I will just leave it. The wife doesn't really care anyway (the Jeep is her daily driver). If I do ever get a real DSP, I can swap the AC LC6i over to the Jeep.

But if you went with components in the front (6.5" mids and 1" high with crossover) wouldn't that free up the inputs you need on the LOC to allow for some rear coaxials?

EDIT: Sorry mistaken inputs for outputs.
