Worth getting a low power amp?

I've got an aftermarket HU which pushes 4x45w. My fronts can take 100rms and 300 peak. My rear can take 75rms 150 peak. Any affordable options worth buying that would make a difference?

Any power ratings given as "peak" are worthless, have no basis in reality. Most head units quote power output from internal amplification in "peak" figures as well, so depending on which head unit you have, when you examine the specs, that 4x45 watts may well be at fully clipped (distorted) output. There is no point in matching equipment based on any "peak" power ratings.

Which head unit are you running? Which exact speakers? Even if an amplifier has very modest RMS ratings, it will usually sound much better than relying on the tiny chip amp in even the best head unit money can buy. I'd take more power from a proper amplifier than what a head unit's internal amp can provide any day of the week.

Your Head unit RMS and peak are not that accurate. My Alpine and most Alpines claim 18W RMS/45W Peak and I can tell you its nowhere even close to the same 45W RMS that their KTP-44U/A puts out.

What speakers are you going to use? Whats the goal of the sound system? Remember, it's a Wrangler.
I have the Alpine KTA-30FW which is 75W RMS and the KTP 45W RMS before. BOTH are plenty of power to drive any speaker in a wrangler and sound amazing.

Do not rely on the headhunts power ratings if you want better sound, especially if you ride with the roof off/down.
Pioneer radios are even worse with RMS ratings.

I've got a MWAuto Android unit - I love it though I do wish I went with a larger screen. My soundbar speakers are the Mopar Kicker and my front speakers are Kicker 43CSS654. I also have the Kicker 11HS8 Hideaway Subwoofer to round it out (I wish I had something louder but I'd say it does pretty well).

My goal is just quality sound that I can play loudly when needed. I'm not an audiophile, but if I can toss $100 or so at my system for a quality low watt amp and get noticeable differences I'd say it's money well spent.



Maybe I'm mistaken but I think I remember that KTP-445 being straight plug and play, correct? It connects between the molex connectors of the speakers and HU? It's been a year since I've installed my HU...a bit foggy of what it looks like back there.



Are there any plans out there for making an under the seat sub box? I could buy one, but I like getting my hands dirty. I'm also a little skeptical of the neo-pod because it's just thin plastic.

^^ something like these should improve things for front and rear speakers without breaking the bank

Many amplifiers in the $100 range are overrated and tend to suck, with lots of brands to stay away from, but PPI and Soundstream (same parent company) from the last several years offer good bang per buck, close to rated power and relatively small footprint.

Certainly have greater power than the alpine, and rated quite well. They are a bit larger though. Do you have one? Where are you (or would you) mounting it?

I agree in general with everything that has been said but you really don't need to amp the soundbar speakers. The rear speakers are very close to your head and in general will run 6-10 db less than the front speakers. So if you are pumping 100 watts to the front speakers you will only need 10-25 watts for the rear speakers. In my setup I just let the head unit provide the power for the rears. I have Audison VOCE speakers up front which are rated at 125 W Continuous Power and use an amp capable of 200 watts x 2. So I only need 12.5 watts to the rear speakers which the head unit can handle with room to spare.

Terry,

I am thinking of going back to my HU running rear speakers.
Right now I have the Alpine i207 rated at 18w RMS, Alpine Power Pack 75w RMS amp and Alpine SPV-65X-WRA speakers rated at 75w RMS.
Also an Alpine PSW-8 sub.

Speakers faded +3 front and rear limited to 100 freq.
So question is fading more front similar to less power? Guess can always bring rear gain down as well. But easier to move speaker wires the way I made it Plug and Play.

Thoughts? Thanks!

I don't have one (yet), I am running an amplified OEM Alpine system.

When the time comes to upgrade audio in the Jeep, I have a few amplifiers that I will likely mount suspended under one of the seats..dry, out of sight.

I agree with comments about not amplifying rear speakers- I would concentrate on front speakers and subwoofer myself.

If youíre running a OEM alpine system, then youíre already amplified. Better speakers and a powered sub is all you need

The primary reason I set mine up the way I did is because I was running my amp to hard in the 5 channel mode. My front speakers want 125w and my sub wants 500w. It only puts out 100w x 4 plus 500w x 1. Once I dialed everything in my amp would over heat after about an hours worth of play. It was then I remembered that AutoEQ set the rear speaker level 6-10 db's less than the front. I changed the amp over to 3 channel mode bridging the front amps giving 200w possible for the front. I only need 125w so the amp runs cooler The 16-18W rms is more than I need or would ever use for the rear speakers.

If your not having a issue with overheating I am not sure I would change anything. You really can't use the extra power if you can bridge your amp though it might be cleaner power.

Oh and I thank you for asking the question. With trying to get moved into the new house I forgot I had a new H/U installed. I need to finish the setup but I have been so busy I totally forgot about it.

Thanks and youíre welcome. While you were in a lot of power to your speakers. I canít imagine how loud your jeep is and how deaf you really are, LOL.

I have the 430N head unit. As an experiment, I EQ'd signal before the head unit, and found the factory Alpine speakers actually aren't too bad, more capable than the 430N allows them to be. The 430N has a strange frequency response curve I am not fond of.

My plan? New Alpine head unit, more power to front speakers and possibly sub, and then re-assess before upgrading anything else. I have a 4 channel amp I intend to use to bi-amp front dash speakers with, and a mono amp to use on the factory subwoofer.

More/cleaner power to the speakers isn't always about SPL- it is also about more control over the speakers and sub in the volume range you listen at.

I had a very good system in my old XJ, totalling about 1400 watts RMS. While that setup could certainly move some air, it was designed for SQ and provided that very nicely. Yes, there was more clean power than my component speakers and subwoofer really required, but that was for headroom purposes- keeping distortion to a minimum while having enough clean output for proper dynamic range.

Yeah I get that and understand that. Still a Wrangler and acoustic suck. But yeah, that power its going to sound great at any level. But unless is all lossless music, not worth it.
Me its basically SiriusXM, Spotify and HD radio Talk shows .
So I donít need that power anymore.

Not really that loud and yes I am really deaf. Speaker design has more to do with loudness than power. All my speakers are SQ not SPL, it is very clean. Maybe wasted on a Jeep but I love it.

Ironically, 98% of my library is Lossless. It has been for years- my old system showcased Lossless formats nicely, so I re-ripped my entire music library into Apple Lossless, and play back in that format from my iPod. Large hard drive for archiving, large capacity playback source, and Lossless is tough to beat compared to carrying hundreds of CDs around. You can transcode back & forth from FLAC to Apple Lossless with no change in audio quality to suit your playback method of choice. I don't do much if any radio, and was disappointed with Sirius to the point I let it lapse, and never looked back.

My old Alpine DVA-9965 head unit was a great-sounding source unit, and could receive HD radio. While we didn't have any content in that format back home in Canada then, I did try it out on road trips through the US, and found it to have much better audio quality than standard FM broadcasts (at least when there was a solid HD signal- the digital HD signal is piggy-backed on the standard FM broadcast, and is designed to revert to standard FM when the HD signal weakens as you get farther away from the transmitting tower).

If it gets you clean output and high quality sound that overcomes the ambient noise in the vehicle, I would say "not wasted."

The Wrangler is the first vehicle I have owned where your front stage is truly in front of you, unlike door-mounted speakers that end up beside you (and showcasing path length differences). While there are some challenges to overcome in terms of where the factory mounts the OEM high frequency drivers, I do enjoy having the sound coming from up front rather than having to resort to digital trickery to get that effect.
