right now in my car i have 2 pioneer premier 6x9s in my rear deck, 85w rms each, powered by a 100w x2 amp. In the front i have 2 jbl gto 6.5s about 40w rms, cant remember for sure, powered by the deck, which is a blaupunkt mp3000 rated at 23w rms per channel. The deck will be replaced by an alpine cde-133bt i have ordered (should be here within the next week). Anyway there has ALWAYS been distortion with heavy bass notes unless i turn the bass down to around 0 or 1 (range is -5 to +5). I have hooked up the amp to the fronts to see if it just maybe wasnt enough for the pioneers but it will distort when hooked to the jbl 6.5's even sooner than the pioneer 6x9s!! So i really dont know if it is just the sh!!ty deck, or if i am asking too much of the speakers or what. But the pioneers are about the best non component 6x9s out there so they should go pretty **** loud i would think. If it is a song with very little bass like a zeppelin song or something like that i can listen to it as loud as i want, but a song like "hear me now" by hollywood undead i have to keep the volume way too low for my liking. So what would you guys recommend i do at this point? I know one thing you might say is also to amp the fronts only but the 6x9s really NEED an amp and the 6.5s do better on HU power than the 6x9's will.

What do you mean by distortion? Like the bass notes or like the vocals are crap? Distortion in general is probably due to the gain being too high on your amp. Where is it set? Try turning the gain down and see if it helps.

Other than that, my advice would be to lose the 6x9's altogether. You really don't need the higher frequencies coming from the rear. And if you're using the 6x9's for sub duty, you'd be waaaaay better off with even a crappy sub in a modest enclosure.

your asking too much out of mids.

what needs to be done is a small sub in the back for low end and set the low pass on the mids and highs.

sounds like you just need to set your gains, and cross overs right, there are threads under the search about setting gains, and all that jizzle jazzle.

we do have a bandpass box with 2 8 inch subs in it now but they are so crappy i dont even bother with them, should i maybe buy 2 more 8 inch subs for it?

his speakers are running off his deck....wtf are u talkin about


u need to buy a 4 channel for ur speakers...ur headunit cant supply the power they need so ur just sending the speakers a dirty signal

well i just did a little test and it looks like i just need more power, i bridged my amp and hooked it to one 6x9 only and i had no more distortion, and the one speaker was putting out more bass than the 2 of them combined before. So how about this amp?

well the rears are amped but they are using a small crappy old jensen, and i cant believe i was so stupid, but i think it may be 100w max per channel, it said 100w+100w or 250w bridged so i figured it was rms. But now i think it has to be max, because if it was 100w rms it would easily be able to push the 6x9s.

Check make sure the polarity is correct on the 6x9 speakers. If the bass sounds better with just one you make have the wires backwards.

yes, i know they are correct, the amp is in the trunk so the wires go directly from the amp to the speakers

Time to upgrade the amp(s) I suppose. Good luck, hope you get it sounding better.


yes, i know they are correct

He didn't say make sure they are connected. He said make sure the + is on the + and - on the - on both speakers correctly.

i should have worded that better, i was just saying there are only 2 connections and they are both visible in the trunk so i can see the positive and negative are hooked up correctly

so you guys think that infinity will be enough power? i will just get a mono block amp if i get a sub
