ok i have my subs and amp and aftermarket speakers but my subs way overpower my speakers and i dont really want to get a head unit because of all the issues with onstar and door chimes and getting it stolen so do yall think a 4 channel amp would get the job done for around $300

 

no doubt about it.

Matter of fact, you can get a pretty damn good amp to push your interior speakers for that much. What speakers are they and what are the specs? I'll make some suggestions for you

 

i just went threw tis on mine also i added a sub box in the trunk and a amp for them.then hooked up a amp just for them. I ended up turnning the amp way down for now so that i wont over power them but still sounds real nice. the factory amp is still hooked up and pshing the rest of the stok speakers.

i love mne and it was about that price but i had to get the install stuff for my car as i didnt have any amp in it already.

but you should look at the hiphonics nemesis amps. they have more the one wattage and they seem to be a solid amp.
ok ill get over the new puppy syndrome
