i was wondering if 2 12" pioneer impp subs and a jensen 600watt amp would work in my 2001 es300. i was also wondering if it would work withougth me having to change my faceplate.
any info would help.
thanks

It will definitely work, you will need a converter it plugs right into the rear 6x9 speakers it won't really be loud but it will make a difference. The converter you splice into the rear speakers and your in business.

you also need to run power wire and a remote for the amp and as stated a line level convertor

get a bigger amp! i got 2 10's that are pioneer imp
i just wanted a lil bang in my lexus and i hae a 750 w jenson amp an they hit like 12's so a 600 watt amp not gonna do much
im gonna be gettin 12's pushing it with 1000 watts hopfully same 12's as yours
but idk about the connection in your lexus but i had to get a new faceplate and stuff

all that will work fine. you may not even need the line output convertor, as i believe the jensen amps have one built in. just splice speaker wire into the input "hi level" side. don't use the rca's. it will be pretty loud, you may want it louder at some point, but it will be fine for a while. i have those pioneers also and they are very good for the price.

^Only problem with that is that is puts more stress on the amp. Or so I've heard.

it really doesn't. that's what they were designed for; i'ts just an electrical circuit built into the amp, seperate from the amplifier portion.

Hmmm so I have an amp with the high level inputs on it. Will I notice better sound than with the line level conterter?

Slooooooow

Makes me kinda wonder too...I've only used a couple of line level converters in the past...I quit using them because of the inevitable noise that seems to come with them - mostly expressed as alternator whine.

I wonder if the "converter" in the amp would perform better?

The amps with the high-level inputs simply have a line-level converter built in to them. You shouldn't notice any diff between a separate converter and the one built into the amp. If you do, you either have a poor quality converter or have an install issue, such as a bad connection or ground loop issue.

Also keep in mind that the process of using speaker level signals for inputs into an amplifier is not going to produce audiophile level sound. It's probably not an issue to most people for subs and bass. When the OEM amplifier takes the input from the head unit and amplifies it, it also is amplifying any noise or unwanted sounds also. Thus when you take the speaker level signal that the amplifer has boosted, and convert it back to line level, you're also getting the unwanted artifacts that were amplified too. End result: more noise, lower sound quality. Now, for subs this is basically a non-issue. With 80hz (or even 120 hz) and below, it's pretty hard (if not impossible) to make out any unwanted sounds. Plus, most unwanted noises that find their way into the system are almost always above the 120hz range. So for subs, tapping into the speaker level leads is a reasonable method. But if you try to use speaker level inputs for mid and high frequencies, and if you have a good set of speakers, you'll notice a sound degradation.

^ WHAT HE said. you could always give it a try and hear how it works.

I'll give it a try this spring when it comes back on the road.

msa13623, that's an excellent description of what went on with my prior experiences with line-level converters. The line level converter was feeding tweets, mids, subs, etc. So I was hearing sub-par sound quality on a full range. The installers were top notch, but I'm VERY picky about my sound quality.

I'll give it at try even sooner. I've got a box with 2 12s and an amp I bought way back and have never used. It has two horn tweeters in there, so I've gotta re-wire the thing so that they're not wired up. Then the subs have the full undivided attention of the amp. I'll wire it in off of one of the 6x9s I guess. It's kind of a cheapish amp, as I recall, so we'll have to see.

Woot! A project for next weekend after the muffler swap Sat. AM.

^Talk about a cheap amp I've got one I took apart lost all the screws and put it back together with packing tape lol.
