Cassette HU

This is for another vehicle of mine (94 Previa) and not for the TL but I need to get a replacement HU because I just replaced all 4 speakers from factory to 5 1/4 Infinity Reference 5002i. I feel that the OEM factory paper cone speakers had better bass so I feel like my JVC HU is plain sh*tty.

Someone told me that Sony HU's are great for internal Bass, is this true? I'm pretty much game for all opinions, basically this is just a beater car so dont want to go too crazy with amps and subs, just a decent amount of bass, right now it sounds horrible (as if I have a bunch of tweeters hooked up).

I need cassette and CD so I'm going to just get a Cassette reciever and add a CD changer so please advise. Thanx!

The model I was told to get: Sony Xplod

And here is a Comparison Chart

After seeing the comparison chart, Sony seems to be the best, but from what I read here everyone hates Sony.. so I am confused now.

If you are wanting more bass out of your new speakers you could have some of the speakers wired out of phase or you could simply just need an outboard amp. First I would check to make sure that all the connections to the speakers are the same (Positive speaker wires from the head unit are going to the same positive input on the speakers, and the same for the negative wires).

Thanx for all the replies guys, someone else actually told me that my speakers might be out of phase.  And I know that I dont have cheap aftermarket speakers, they are decent, Infinity Reference 5002i's.  I went into the store and played with a couple of a headunits, and listened to the same music on 3 different HU's on the same 5.25 Pioneer 2 way speakers that the store had on the wall.  And it seemed that, the Pioneer sounded much cleaner and distinct in all (lows, mids, and highs) compared to Sony and JVC.  JVC was the worst and Sony was 2nd best.  And what is funny is that Sony had more watts going being put out.  So I think I'm going to try Pioneer now.

Hmmm, <looks at things backwards> was the JVC driving the factory speakers before? If so it is not a head unit issue that you have, it is a speaker issue. Some speakers just sound different than others and some paper cone stockers I would leave in the vehicle before buying the name brand 2 or 3 ways with blue mica filled superlightweight cones with glowing leds and supertweeters that are aluminum coated and rotational and handle 600000 watts. To me it sure sounds like a speaker issue.

I'm pretty sure its not the Speakers because these speakers aren't sh*tty.  They are Infinity 5002i at about $50 a pair.  And also, the JVC head unit, flickers like crazy when I push the volume up.

Your right, someone else told me to check this as well, so I'm going to go out tommorow and check that out.  Thanx.

I was looking at a Fit Guide for Toyota Previas.  It shows that it can accept up to a 7 inch cone for the rear speakers.  If your factory speaker was 7inches, and you replaced it with a 5.25 inch speaker, that could have an affect on your bass response. 

Another solution is buying some cheap 6x9 inch speakers and a Q-logic 6x9in box (about $30).  You can use the 6x9's in the back of the car as a replacement to the infinity's in the rear.  6x9's are pretty good at putting out low frequencies.   This solution allows you to keep the JVC (usually JVC has some decent products) head unit...

I think the Fit guide specifies the rear quarter panel in which there is a cut out for a subwoofer.  And that spot might handle that big of a speaker, cuz from what I recall, the fronts are 4 inch speakers and the rears were 5 inch speakers, and fitting these 5.25's was a pain as it is.  So I know anything bigger would not be possible.  The subwoofer compartment towards the lift gate however seems to have a cut out for a 6x9 and that is where I want to add a small sub if the change in Head Unit doesn't make things better. 

first and foremost, yes indeed check phase of your speakers... sweep the balance control all the way to one side... how does it sound? sweep it all the way to the other side, how does it sound? now put it back in the middle... how does it sound?  if it sounds like you are listening to it in a wind tunnel in the middle position you have a speaker out of phase...

if however, they are in phase you may want to consider that forbidden/Rob had a valid point.... how did the OEM speakers sound with the JVC HU?   good?    then why blame the HU?

many people when replacing speakers dont take into account the different efficiencies of the speakers... a factory (OEM) speaker as a rule tends to be very efficient whereas aftermarket speakers ( especially better quality ones ) tend not to be..... it sounds like you simply need more oomph to now power these Infinitys vs. your OEM speakers and now you are finding that the JVC doesnt have that oomph.... it's not a fault of the HU per se..... many people going from cheaper, efficient OEM speakers to an upgraded speaker find that deck power suddenly doesnt do it anymore..... which is why a simple upgrade often snowballs into adding an amp, then a battery, then an alternator to charge the battery, etc, etc.....

if your Infinity speakers need a little more power to make them shine i dont see what swapping head units will do unless you plan on adding a power amp to that new head unit....... regardless of brand i doubt if you'll be happy simply running deck power....
